Subject: [amibroker] Saving Color Schemes
Hi,
I can't seem to figure out if it is possible to save different color
schemes. Saving Templates does not work for colors for me.
If this is not possible then I would be happy if I could control the
background color within AFL but can't find anything for that either.
This is unimportant but if anybody has any suggestions I would
appreciate it.
Thanks,
Anthony

Subject: Two separate installations (not instances) of AB?
Here is one for our esteemed leader and programmer and customer service
representative...
Tomasz: I have been told that older versions of AB (4.20 perhaps) might
optimize faster because of less program overhead. No charting, or
commentary, or other stuff needed...just basic optimization crunching.
I know AB is the fastest thing around, but could I get a faster
optimization run complete with an older version? Be candid!
If the answer is yes, is it possible to install an older version in a
separate directory than the current, uptodate version? Would there be
interferences in the Registry? Would the current version operate
independently from the older version?
I have also heard that breaking up complex single line coded statements
into components will enhance the speed of an optimization. Is this
true?
Ken

Subject: RE: How to duplicate AB setup between computers?
I think most of the settings are in the various broker.* charts found in
your AB directory (program files\amibroker. I would think you could simply
copy them all. I have not tried this but it seems logical. Note if you copy
to a CD you might want to use winZip to compress the files. This avoids
changing some of the file flags.

Subject: Re: The Watered Down Semi-Interesting System
Sid,
The ideas of asymmetrical long/short signals and exits is certainly
not new. Eons ago as a purist I for some reason thought this needed
to be the case, but that logic ?! has long since been discarded.
This watered down version is no where near as good as the full blown
version, but it's intreresting to see what simplistic little systems
like this can do.
If you are referring the the equity line graph, the code is in the
files section.

If I implement changes into AB I have always the speed in mind.
Therefore newer versions should perform at least that fast as old ones.
In fact some enhancements have been made so 4.xx versions are
faster than 3.xx versions.
As far as 4.20 vs 4.29 are considered there is no difference.

THe best way to increase speed is to use variables whenever you can.
Instead of calling for example Foreign("$INDU","c") many times in your
code call it once and assign result to the variable.

About box.
CHANGES FOR VERSION 4.29.5 (as compared to 4.29.1)
a.. fixed crash in AFL editor that occured when selecting all text and
choosing right mouse button -> copy
b.. auto-scaling changed slightly
c.. user-definable thousand separator (in Tools->Preferences->Misc)
applied automatically to all list views and indicators and WriteVal function
d.. definable number of decimal places in RT quote window
(Tools->Prefs->Misc)
e.. watch-list related functions: (available from context menu in tree and
Symbol->Watch list menu)
f.. quick type-in symbols into watch list
g.. import/export watch list from/to .LST file and from/to plugin (ext.
database only for plugins that support this feature. The first one will be
FT plugin)
h.. context menu is displayed over selected watch list (click with right
mouse button on the watch list name in the Workspace window)
i.. 'dirty' flag is set properly after moving/sizing the study
j.. Amibroker again displays message box asking to save changes. (this is
useful to undo some unwanted changes but it works only for most recent
'in-memory' symbols (see Tools->Preferernces->Data))
k.. fixed the case when Preferences has log scale switched OFF but
Indicator Builder has "log scale" turned ON for Price chart.
CHANGES FOR VERSION 4.29.1 (as compared to 4.29.0)
a.. data tooltips now show study ID and coordinates and point/percent
change from start to end when you hover the mouse pointer over the trend
line or other study
b.. from-to range selector implemented just double click on chart to mark
begin and then double click in other place to mark end of the range. > and <
markers will appear above date axis. To delete the markers double click
again in the same place where vertical line is positioned.
c.. From-to selected range can be referred from the AFL level via new
functions
BeginValue( ARRAY )
EndValue( ARRAY )
- these functions give the single value (number) of the ARRAY at the
beginning and end of the selected range. If no range is marked then they
return the value at the first bar and last bar respectively.
Example:
WriteVal( BeginValue( DateTime() ), formatDateTime );
WriteVal( EndValue( DateTime() ), formatDateTime );
"Precentage change of close is " +
WriteVal( 100 * (EndValue( Close ) - BeginValue( Close ))/BeginValue(
Close ) ) + "%";
d.. WriteVal function now handles formatDateTime
WriteVal( DateTime(), formatDateTime );
e.. Zoom to range implemented (View->Zoom->Range) or hold down both SHIFT
and CTRL and click on green zoom in toolbar button (zooms to selected
from-to range)
CHANGES FOR VERSION 4.29.0 (as compared to 4.28.1)
a.. context help in AFL editor - just press F1 when cursor is over AFL
reserved function name and it will display full information about that
function
b.. param info/fun reference available also from context menu
c.. fixed bug in Study function working improperly for trendlines with
right extend property
d.. tab order fixed in Study properties box
e.. usability: "Filter pre/after hours" is available now from
View->Intraday menu
f.. new AFL function:
Now( format = 0 ) returns current date / time in numerous of formats:
format = 0 - returns string containing current date/time formatted
according to system settings
format = 1 - returns string containing current date only formatted
according to system settings
format = 2 - returns string containing current time only formatted
according to system settings
format = 3 - returns DATENUM number with current date
format = 4 - returns TIMENUM number with current time
format = 5 - returns DATETIME number with current date/time
See: http://www.amibroker.com/guide/afl/afl_view.php?name=NOW
g.. new drawing tool: Triangle
h.. new drawing tool: Andrews' Pitchfork
i.. Gann Square tool does not draw controlling trenline during move/resize
j.. added check that prevents freeing memory by Equity(1) function when
this memory is referenced by other variables
k.. added Layer combo to the Text properties box
l.. added link to AFL on-line reference to the Help->AmiBroker on the Web
menu.
m.. switching layers does not cause unnecessary symbol tree refresh
n.. added switch to AA Settings->Report tab that allows to turn off optimi
zation warning (that is displayed if optimization requires more than 300
steps)
o.. other minor fixes.
CHANGES FOR VERSION 4.28.1 (as compared to 4.28.0)
a.. fixed problem with missing some short trades when new flag "Reverse
entry signal forces exit" was turned off
b.. Null is now highlighted and present in the auto-complete box.
c.. fixed numeric sorting of colorized columns
CHANGES FOR VERSION 4.28.0 (as compared to 4.27.1)
a.. ApplyStop has one more parameter
ApplyStop( Type, Mode, Amount, ExitAtStop, Volatile = False )
new Volatile parameters decides if amount (or distance) (3rd parameter) is
sampled at the trade entry and remains fixed during the trade (Volatile =
FALSE - old behaviour) or if can vary during the trade (Volatile = TRUE)
Allows single-line implementation of Chandeliers exit:
ApplyStop(stopTypeTrailing, stopModePoint, 3*ATR(14), True, True );
b.. ApplyStop handles new N-Bar stop - exits the trade after N bars.
Type = stopTypeNBar; /* = 3 */
Mode = stopModeBars; /* = 1 */
ApplyStop( stopTypeNBar, stopModeBars, 5 ); // exits trades on 5th bar
since entry
c.. added new "Reverse entry signal forces exit" check box to the
Backtester settings.
When it is ON (the default setting) - backtester works as in previous
versions and closes already open positon if new entry signal in reverse
direction is encountered. If this switch is OFF - even if reverse signal
occurs backtester maintains currently open trade and does not close positon
until regular exit (sell or cover) signal is generated.
In other words when this switch is OFF backtester ignores Short signals
during long trades and ignores Buy signals during short trades.
d.. added "Allow same bar exit (single bar trade)" option to the Settings
When it is ON (the default settings) - entry and exit at the very same bar
is allowed (as in previous versions)
if it is OFF - exit can happen starting from next bar only (this applies
to regular signals,there is a separate setting for ApplyStop-generated
exits). Switching it to OFF allows to reproduce the behaviour of MS
backtester that is not able to handle same day exits.
e.. long trades now take precedence over short trades so if signals happen
on the same bar in both directions only long trade is taken.
f.. new AFL functions:
DateTime() - returns array of encoded date/time values suitable for using
with
AddColumn and formatDateTime constant
to produce date time formated according to your system settings
AddColumn( DateTime(), "Date / Time", formatDateTime );
new formatChar constant allows outputting single ASCII character codes:
Example (produces signal file accepted by various other programs):
Buy=Cross(MACD(),Signal());
Sell=Cross(Signal(), MACD());
Filter=Buy OR Sell;
SetOption("NoDefaultColumns", True );
AddColumn( DateTime(), "Date", formatDateTime );
AddColumn( IIf( Buy, 66, 83 ), "Signal", formatChar );
g.. new AFL functions continued:
BarIndex() - returns zero-based bar number -
the same as Cum(1)-1 but it is much faster than Cum(1) when used in
Indicators
SetOption( "name", value )
- sets various options in automatic analysis settings currently available
options are
"NoDefaultColumns" - if set to True - exploration does not have default
Ticker and Date/Time columns
"InitialEquity"
"AllowSameBarExit"
"ActivateStopsImmediately"
"AllowPositionShrinking"
"FuturesMode"
"InterestRate"
h.. if you overwrite AA settings via SetTradeDelays/SetOption
backtest report gives these actual values instead of originaly set in the
settings
i.. new Null constant is equal to -1e10 (empty value) so you can use it
instead enigmatic -1e10
obsolete styleLog removed (logarithmic scale setting is not per-line but
per-pane and it is selectable from Indicator Builder)
j.. added PlotGrid( level, color = colorDefault ) function that plots grid
line using built-in dotted style.
k.. fixed problem with QuoteEditor that was introduced with adding color
support to the list view
l.. added support for Win XP common controls 6, which results in enhanced
XP-look (on WinXP only of course)
m.. fixed zero-size problem with floating control bars on Windows XP
n.. fixed some compatibility issues with common controls 6.
o.. added sound when plugin status changes
p.. fixed problems with Review window sometimes not showing the results
q.. value label drawing changed slightly
r.. status bar adjusted so plugin state is visible on smaller displays
s.. improved windows version checking for bug reports
CHANGES FOR VERSION 4.27.1 (as compared to 4.27.0)
a.. fixed problems with auto-complete and param info features appearing on
certain Windows versions
CHANGES FOR VERSION 4.27.0 (as compared to 4.26.0)
Intellisense-like functionality in AFL editor
a.. auto-completion feature in AFL editor type a few letters and press
Ctrl+SPACE and the number of matching functions / reserved words will be
displayed
b.. parameters-info tip, type function name and opening brace ( and you
will see the tip that shows information about required parameters
c.. two new checkboxes Preferences->Editor control Auto-completion /
parameter-info features
d.. fixed exception occuring when optimizing systems that generate zero
trades (very rare case)
e.. AlertIF called from the custom indicators sometimes displayed wrong
date/time - now it is fixed
f.. when fixup = 1 Foreign() is able to align array past the last foreign
bar. For example when using intraday data you can refer to imported EOD data
and it will fill intraday data with last value from previous day.
CHANGES FOR VERSION 4.26.0 (as compared to 4.25.0)
a.. List view sorting speed increased significantly:
a.. sorting of text columns is 2 times faster (on average)
b.. sorting of numeric column is 5-10 times faster ( sort 660'000 items
within 2-3 seconds on 1GHz machine)
b.. Explorations now support definable color of cell text and background
AddColumn and AddTextColumn functions extended to support this feature:
AddColumn( Array, "Title", format = 1.2, textColor = colorDefault,
bkgndColor = colorDefault );
AddTextColumn( "Text", "Title", format = 1.2, textColor = colorDefault,
bkgndColor = colorDefault );
New colorDefault constant (-1) defines default windows color for grid
cell.
Sample code:
Filter =1;
AddColumn( Close, "Close", 1.2 );
AddColumn( MACD(), "MACD", 1.4 , IIf( MACD() > 0, colorGreen,
colorRed ) );
AddTextColumn( FullName(), "Full name", 77 , colorDefault, IIf( Close <
10, colorLightBlue, colorDefault ) );
c.. custom indicators - anchors are not offset vertically from the ends of
the trend line when Draw dates is selected
d.. custom indicators with auto-scaling can be now dragged in Y-direction
like regular charts
e.. Foreign and RelStrength algorithm improved to allow more complex
alignment cases
f.. PlotShapes works even without any Plot statement (although it is
intended to use in conjunction with Plot)
g.. fixed line disappearing bug that occured when using text tool right
after trend line tool
h.. Dec is displayed again on date axis
CHANGES FOR VERSION 4.25.0 (as compared to 4.24.0)
a.. support user-definable parameters:
new AFL functions
Param( "name", default, min, max, step )
ParamStr( "name", "default" );
ParamColor( "name", defaultcolor );
new Parameters dialog : right click over chart pane and select
"Parameters" or press Ctrl+R
allows to change chart parameters - changes are reflected immediatelly
Sample code 1:
ticker = ParamStr( "Ticker", "MSFT" );
sp = Param( "MA Period", 12, 2, 100 );
PlotForeign( ticker, "Chart of "+ticker, ParamColor( "Price Color",
colorLightYellow ), styleCandle );
Plot( MA( Foreign( ticker, "C" ), sp ), "MA(" + WriteVal( sp, 1.0 ) + ")",
ParamColor( "MA Color", colorRed ) );
Sample code 2:
sp = Param( "RSI Period", 12, 2, 100 );
r = RSI( sp );
Plot( r, "RSI("+WriteVal(sp,1.0)+")", ParamColor("RSI Color",
colorRed ) );
Buy = Cross( r, 30 );
Sell = Cross( 70, r );
PlotShapes( shapeUpArrow * Buy + shapeDownArrow * Sell, IIf( Buy,
colorGreen, colorRed ) );
b.. added missing ':' and '"' characters to the forbidden characters set
in file names generated from ticker names. All file-system reserved
characters are converted to underscore.
c.. ticker symbol maximum length increased to 25 characters (from previous
15).
(these two fixes above solve problem with using very long symbols like
d.. default keyboard accelerators changed Ctrl+R is now for Parameters
dialog F5 is for Refresh
e.. fixed calculation bug occuring when drawing objects in the blank chart
area ("jumping" effect)
f.. new method in Quotations collection for faster retrieval of quotes
long Retrieve( long Count, Variant *Date, Variant *Open, Variant *High,

/* create AB object */
AB = new ActiveXObject("Broker.Application");
/* retrieve automatic analysis object */
AA = AB.Analysis;
/* load formula from external file */
AA.LoadFormula("afl\\macd_c.afl");
/* optional: load settings */
// AA.LoadSettings("the_path_to_the_settings_file.abs");
/* setup filters */
/* backtest over symbols present in market 0 only (zero-based number) */
AA.ClearFilters();
AA.Filter( 0, "market" ) = 0;
/* set apply to and range */
AA.ApplyTo = 2; // use filters
AA.RangeMode = 0; // use all available quotes
/* run backtest and display report */
AA.Backtest();
AA.Report(""); // empty file name means display report
CHANGES FOR VERSION 4.23.0 (as compared to 4.22.1)
a.. chart axis font can be defined by the user. The default is now Arial,
9pt.
(Tools->Preferences->Miscellaneous: "Axis font")
b.. Undo feature added to AFL editor.
c.. PlotShapes now supports offset (or distance) parameter (by
default -12 ), Offset is expressed in SCREEN pixels.
Negative offsets shift symbols down, positive offsets shift symbol up. To
place the shape exactly at ypostion, specify 0 as offset.
PlotShapes( shape, color, layer = 0, yposition = graph0, offset = -12 );
d.. yet another bug fixed that caused problems with drawing lines when
multiple windows were showing same symbol but different intervals.
e.. if Y-value is less than 1000 the status bar displays four decimal
places , also bar number is displayed in the status bar (next to date/time)
f.. Insert Indicator window (Ctrl+I) does not show empty indicator slots
anymore.
CHANGES FOR VERSION 4.22.1 (as compared to 4.22.0)
a.. fixed overwrite problem occuring when deleting first indicator in the
list in Indicator Builder
b.. fixed shortcut conflict &File and &Format. Now Format menu has Alt+o
shortcut
c.. other minor fixes
d.. added constants for shapes
"shapeNone", 0
"shapeUpArrow", 1
"shapeDownArrow", 2
"shapeHollowUpArrow", 3
"shapeHollowDownArrow", 4
"shapeSmallUpTriangle", 5
"shapeSmallDownTriangle", 6

"shapeDigit8", 49
"shapeDigit9", 51
"shapePositionAbove", 1
Example:
PlotShapes( IIF( buy, shapeDigit9 + shapePositonAbove, shapeNone ),
colorGreen );
CHANGES FOR VERSION 4.22.0 (as compared to 4.21.1)
a.. changes made in Indicator Builder are not lost if formula is
incorrect - instead error message is displayed and formula is saved even if
it has a syntax error
b.. if currently displayed indicator formula has an error - the error
message does not pop up in a separate window but is displayed in the
indicator pane.
c.. empty indicators are not displayed in the Indicator Builder and new
buttons "Add", "Delete" are provided to add new indicator and remove
existing
d.. when drawing or moving drawing objects the auto-refresh of the chart
is temporarily held to solve problems with drawing on RT charts.
e.. Symbol->Information window is not reset every 3 sec when working with
RT data.
f.. interval between chart updates is now configurable
(Preferences->Intraday)
g.. Random( seed = none ); function takes new parameter seed.
If seed is defined it initializes the seed of random number generator this
allows to produce repetitive series of pseudo-random series. If seed is not
specified - random number generator continues generation.
To reinitialize the generator, use 1 as the seed argument. Any other value
for seed sets the generator to a random starting point.
Example 1:
Graph0 = Random(); // generates different sequence with each refresh
Example 2:
Graph0 = Random(1); // generates the same sequence with each refresh
h.. new AFL function
PlotShapes( shape, color, layer = 0, yposition = graph0 );
that allows to plot arrows and other shapes on any chart.
Parameters:
a.. shape defines type of the symbol. when shape is zero nothing is
plotted
values other than zero cause plotting various pre-defined shapes.
Odd values plot shape BELOW indicator, even values plot shape ABOVE
indicator.
b.. color defines color of shape
c.. layer defines layer number on which shapes are plotted
d.. yposition defines Y-position where shapes are plotted (by default
they are plotted 'around' graph0 (first indicator) line)
Currently defined shapes are
UP ARROW = 1, (below indicator)

Demo formula:
Graph0=MACD();
Graph1=Signal();
Buy=Cross(Graph0, Graph1);
Sell=Cross(Graph1, Graph0);
PlotShapes( ( Buy OR Sell ) * ( 1 + Cum( Buy OR Sell ) % 52 ), IIf( Buy,
colorGreen, colorRed ), 5 );
GraphXSpace = 5;

I'm not sure if I'm better described as a "dimmer bulb" or a "dimmer blob".
Either way, I am trying to make the transition. I still use MS to post
"charts" (like some of the more astute players at this forum). It still
makes pretty pictures.
To dissemenate my daily institutional recommendations, I had to bypass MS
and pull the esignal feed into Excel (for compliance reasons).
Take care...dimmer and slimmer,

Yes, that is what I was looking for...thanks.
For others wanting to use these indicators it looks like you need to add
them to the bottom of your AA system test and then copy the whole thing
over to a new custom indicator to make all the parameters available to the
plots.

Sid,
You only need to replace the AB built in equity line indicator with
this code. (SAVE THE ORIGINAL FIRST under another name). Then by
just clicking the equity button in any AA window after doing a
backtest will plot it.

Al,
No. In the formula
the numbers have to be typed like in any programming language without
thousand separators.

Thanks so much, TJ, for the thousands separator for large numbers. This
will be a big help. Question: when inputting a large number in the AA
window, can you use the thousands separator in formulas? Like in:
PositionSize = 100,000;

Thanks Jayson,
I thought that was the case but I wanted to check with someone more
knowledgeable. I was just trying to have a different background color
for a particular indicator window.
Cheers,

AmiBroker 4.29.5 Beta Read Me
February 20, 2003 18:06
THIS IS A BETA VERSION OF THE SOFTWARE. EXPECT BUGS.
Backup your data files and entire AmiBroker folder first!
INSTALLATION INSTRUCTIONS
IMPORTANT: This archive is update-only. You have to install full version
4.20 first.
Just run the installer and follow the instructions.
Then run AmiBroker. You should see "AmiBroker 4.29.5 beta" written in
the About box.
CHANGES FOR VERSION 4.29.5 (as compared to 4.29.1)
* fixed crash in AFL editor that occured when selecting all text
and choosing right mouse button -> copy
* auto-scaling changed slightly
* user-definable thousand separator (in
Tools->Preferences->Misc) applied automatically to all list views and
indicators and WriteVal function
* definable number of decimal places in RT quote window
(Tools->Prefs->Misc)
* watch-list related functions: (available from context menu in
tree and Symbol->Watch list menu)
* quick type-in symbols into watch list
* import/export watch list from/to .LST file and from/to plugin
(ext. database only for plugins that support this feature. The first one
will be FT plugin)
* context menu is displayed over selected watch list (click with
right mouse button on the watch list name in the Workspace window)
* 'dirty' flag is set properly after moving/sizing the study
* Amibroker again displays message box asking to save changes.
(this is useful to undo some unwanted changes but it works only for most
recent 'in-memory' symbols (see Tools->Preferernces->Data))
* fixed the case when Preferences has log scale switched OFF but
Indicator Builder has "log scale" turned ON for Price chart.
CHANGES FOR VERSION 4.29.1 (as compared to 4.29.0)
* data tooltips now show study ID and coordinates and
point/percent change from start to end when you hover the mouse pointer
over the trend line or other study
* from-to range selector implemented just double click on chart
to mark begin and then double click in other place to mark end of the
range. > and < markers will appear above date axis. To delete the
markers double click again in the same place where vertical line is
positioned.
* From-to selected range can be referred from the AFL level via
new functions
BeginValue( ARRAY )
EndValue( ARRAY )
- these functions give the single value (number) of the ARRAY at the
beginning and end of the selected range. If no range is marked then they
return the value at the first bar and last bar respectively.
Example:
WriteVal( BeginValue( DateTime() ), formatDateTime );
WriteVal( EndValue( DateTime() ), formatDateTime );
"Precentage change of close is " +
WriteVal( 100 * (EndValue( Close ) - BeginValue( Close ))/BeginValue(
Close ) ) + "%";
* WriteVal function now handles formatDateTime
WriteVal( DateTime(), formatDateTime );
* Zoom to range implemented (View->Zoom->Range) or hold down
both SHIFT and CTRL and click on green zoom in toolbar button (zooms to
selected from-to range)
CHANGES FOR VERSION 4.29.0 (as compared to 4.28.1)
* context help in AFL editor - just press F1 when cursor is over
AFL reserved function name and it will display full information about
that function
* param info/fun reference available also from context menu
* fixed bug in Study function working improperly for trendlines
with right extend property
* tab order fixed in Study properties box
* usability: "Filter pre/after hours" is available now from
View->Intraday menu
* new AFL function:
Now( format = 0 ) returns current date / time in numerous of formats:
format = 0 - returns string containing current date/time formatted
according to system settings
format = 1 - returns string containing current date only formatted
according to system settings
format = 2 - returns string containing current time only formatted
according to system settings
format = 3 - returns DATENUM number with current date
format = 4 - returns TIMENUM number with current time
format = 5 - returns DATETIME number with current date/time
See: http://www.amibroker.com/guide/afl/afl_view.php?name=NOW
* new drawing tool: Triangle
* new drawing tool: Andrews' Pitchfork
* Gann Square tool does not draw controlling trenline during
move/resize
* added check that prevents freeing memory by Equity(1) function
when this memory is referenced by other variables
* added Layer combo to the Text properties box
* added link to AFL on-line reference to the Help->AmiBroker on
the Web menu.
* switching layers does not cause unnecessary symbol tree
refresh
* added switch to AA Settings->Report tab that allows to turn
off optimization warning (that is displayed if optimization requires
more than 300 steps)
* other minor fixes.
CHANGES FOR VERSION 4.28.1 (as compared to 4.28.0)
* fixed problem with missing some short trades when new flag
"Reverse entry signal forces exit" was turned off
* Null is now highlighted and present in the auto-complete box.
* fixed numeric sorting of colorized columns
CHANGES FOR VERSION 4.28.0 (as compared to 4.27.1)
* ApplyStop has one more parameter
ApplyStop( Type, Mode, Amount, ExitAtStop, Volatile = False )
new Volatile parameters decides if amount (or distance) (3rd parameter)
is sampled at the trade entry and remains fixed during the trade
(Volatile = FALSE - old behaviour) or if can vary during the trade
(Volatile = TRUE)
Allows single-line implementation of Chandeliers exit:
ApplyStop(stopTypeTrailing, stopModePoint, 3*ATR(14), True, True );
* ApplyStop handles new N-Bar stop - exits the trade after N
bars.
Type = stopTypeNBar; /* = 3 */
Mode = stopModeBars; /* = 1 */
ApplyStop( stopTypeNBar, stopModeBars, 5 ); // exits trades on 5th bar
since entry
* added new "Reverse entry signal forces exit" check box to the
Backtester settings.
When it is ON (the default setting) - backtester works as in previous
versions and closes already open positon if new entry signal in reverse
direction is encountered. If this switch is OFF - even if reverse signal
occurs backtester maintains currently open trade and does not close
positon until regular exit (sell or cover) signal is generated.
In other words when this switch is OFF backtester ignores Short signals
during long trades and ignores Buy signals during short trades.
* added "Allow same bar exit (single bar trade)" option to the
Settings
When it is ON (the default settings) - entry and exit at the very same
bar is allowed (as in previous versions)
if it is OFF - exit can happen starting from next bar only (this applies
to regular signals,there is a separate setting for ApplyStop-generated
exits). Switching it to OFF allows to reproduce the behaviour of MS
backtester that is not able to handle same day exits.
* long trades now take precedence over short trades so if
signals happen on the same bar in both directions only long trade is
taken.
* new AFL functions:
DateTime() - returns array of encoded date/time values suitable for
using with
AddColumn and formatDateTime constant
to produce date time formated according to your system settings
AddColumn( DateTime(), "Date / Time", formatDateTime );
new formatChar constant allows outputting single ASCII character codes:
Example (produces signal file accepted by various other programs):
Buy=Cross(MACD(),Signal());
Sell=Cross(Signal(), MACD());
Filter=Buy OR Sell;
SetOption("NoDefaultColumns", True );
AddColumn( DateTime(), "Date", formatDateTime );
AddColumn( IIf( Buy, 66, 83 ), "Signal", formatChar );
* new AFL functions continued:
BarIndex() - returns zero-based bar number -
the same as Cum(1)-1 but it is much faster than Cum(1) when used in
Indicators
SetOption( "name", value )
- sets various options in automatic analysis settings currently
available options are
"NoDefaultColumns" - if set to True - exploration does not have default
Ticker and Date/Time columns
"InitialEquity"
"AllowSameBarExit"
"ActivateStopsImmediately"
"AllowPositionShrinking"
"FuturesMode"
"InterestRate"
* if you overwrite AA settings via SetTradeDelays/SetOption
backtest report gives these actual values instead of originaly set in
the settings
* new Null constant is equal to -1e10 (empty value) so you can
use it instead enigmatic -1e10
obsolete styleLog removed (logarithmic scale setting is not per-line but
per-pane and it is selectable from Indicator Builder)
* added PlotGrid( level, color = colorDefault ) function that
plots grid line using built-in dotted style.
* fixed problem with QuoteEditor that was introduced with adding
color support to the list view
* added support for Win XP common controls 6, which results in
enhanced XP-look (on WinXP only of course)
* fixed zero-size problem with floating control bars on Windows
XP
* fixed some compatibility issues with common controls 6.
* added sound when plugin status changes
* fixed problems with Review window sometimes not showing the
results
* value label drawing changed slightly
* status bar adjusted so plugin state is visible on smaller
displays
* improved windows version checking for bug reports
CHANGES FOR VERSION 4.27.1 (as compared to 4.27.0)
* fixed problems with auto-complete and param info features
appearing on certain Windows versions
CHANGES FOR VERSION 4.27.0 (as compared to 4.26.0)
Intellisense-like functionality in AFL editor
* auto-completion feature in AFL editor type a few letters and
press Ctrl+SPACE and the number of matching functions / reserved words
will be displayed
* parameters-info tip, type function name and opening brace (
and you will see the tip that shows information about required
parameters
* two new checkboxes Preferences->Editor control Auto-completion
/ parameter-info features
* fixed exception occuring when optimizing systems that generate
zero trades (very rare case)
* AlertIF called from the custom indicators sometimes displayed
wrong date/time - now it is fixed
* when fixup = 1 Foreign() is able to align array past the last
foreign bar. For example when using intraday data you can refer to
imported EOD data and it will fill intraday data with last value from
previous day.
CHANGES FOR VERSION 4.26.0 (as compared to 4.25.0)
* List view sorting speed increased significantly:
o sorting of text columns is 2 times faster (on average)
o sorting of numeric column is 5-10 times faster ( sort 660'000
items within 2-3 seconds on 1GHz machine)
* Explorations now support definable color of cell text and
background
AddColumn and AddTextColumn functions extended to support this feature:
AddColumn( Array, "Title", format = 1.2, textColor = colorDefault,
bkgndColor = colorDefault );
AddTextColumn( "Text", "Title", format = 1.2, textColor = colorDefault,
bkgndColor = colorDefault );
New colorDefault constant (-1) defines default windows color for grid
cell.
Sample code:
Filter =1;
AddColumn( Close, "Close", 1.2 );
AddColumn( MACD(), "MACD", 1.4 , IIf( MACD() > 0, colorGreen, colorRed )
);
AddTextColumn( FullName(), "Full name", 77 , colorDefault, IIf( Close <
10, colorLightBlue, colorDefault ) );
* custom indicators - anchors are not offset vertically from the
ends of the trend line when Draw dates is selected
* custom indicators with auto-scaling can be now dragged in
Y-direction like regular charts
* Foreign and RelStrength algorithm improved to allow more
complex alignment cases
* PlotShapes works even without any Plot statement (although it
is intended to use in conjunction with Plot)
* fixed line disappearing bug that occured when using text tool
right after trend line tool
* Dec is displayed again on date axis
CHANGES FOR VERSION 4.25.0 (as compared to 4.24.0)
* support user-definable parameters:
new AFL functions
Param( "name", default, min, max, step )
ParamStr( "name", "default" );
ParamColor( "name", defaultcolor );
new Parameters dialog : right click over chart pane and select
"Parameters" or press Ctrl+R
allows to change chart parameters - changes are reflected immediatelly
Sample code 1:
ticker = ParamStr( "Ticker", "MSFT" );
sp = Param( "MA Period", 12, 2, 100 );
PlotForeign( ticker, "Chart of "+ticker, ParamColor( "Price Color",
colorLightYellow ), styleCandle );
Plot( MA( Foreign( ticker, "C" ), sp ), "MA(" + WriteVal( sp, 1.0 ) +
")", ParamColor( "MA Color", colorRed ) );
Sample code 2:
sp = Param( "RSI Period", 12, 2, 100 );
r = RSI( sp );
Plot( r, "RSI("+WriteVal(sp,1.0)+")", ParamColor("RSI Color", colorRed )
);
Buy = Cross( r, 30 );
Sell = Cross( 70, r );
PlotShapes( shapeUpArrow * Buy + shapeDownArrow * Sell, IIf( Buy,
colorGreen, colorRed ) );
* added missing ':' and '"' characters to the forbidden
characters set in file names generated from ticker names. All
file-system reserved characters are converted to underscore.
* ticker symbol maximum length increased to 25 characters (from
previous 15).
(these two fixes above solve problem with using very long symbols like
* default keyboard accelerators changed Ctrl+R is now for
Parameters dialog F5 is for Refresh
* fixed calculation bug occuring when drawing objects in the
blank chart area ("jumping" effect)
* new method in Quotations collection for faster retrieval of
quotes
long Retrieve( long Count, Variant *Date, Variant *Open, Variant *High,
Variant *Low, Variant *Close, Variant *Volume, Variant *OpenInt );
* on Windows Me, 2000 and XP all file dialogs now feature
"Places" bar and allows to select few recent file names from the combo
* date axis display modified slightly (3 letter month abbrev.
used more often
* changed resizing algorithm so if "no min size for resizing
dialog" option is selected the scroll bar of list / edit is always
visible. Also the option is active from the start without need to go to
Preferences.
* other minor improvements
CHANGES FOR VERSION 4.24.0 (as compared to 4.23.0)
* saving/loading Automatic Analysis settings to/from the file

Filter( 1, "market" ) = 2; // exclude 2nd market
Full Example for Windows Scripting Host:
========================================
/* create AB object */
AB = new ActiveXObject("Broker.Application");
/* retrieve automatic analysis object */
AA = AB.Analysis;
/* load formula from external file */
AA.LoadFormula("afl\\macd_c.afl");
/* optional: load settings */
// AA.LoadSettings("the_path_to_the_settings_file.abs");
/* setup filters */
/* backtest over symbols present in market 0 only (zero-based number) */
AA.ClearFilters();
AA.Filter( 0, "market" ) = 0;
/* set apply to and range */
AA.ApplyTo = 2; // use filters
AA.RangeMode = 0; // use all available quotes

Arial, 9pt.
(Tools->Preferences->Miscellaneous: "Axis font")
* Undo feature added to AFL editor.
* PlotShapes now supports offset (or distance) parameter (by
default -12 ), Offset is expressed in SCREEN pixels.
Negative offsets shift symbols down, positive offsets shift symbol up.
To place the shape exactly at ypostion, specify 0 as offset.
PlotShapes( shape, color, layer = 0, yposition = graph0, offset = -12 );
* yet another bug fixed that caused problems with drawing lines
when multiple windows were showing same symbol but different intervals.
* if Y-value is less than 1000 the status bar displays four
decimal places , also bar number is displayed in the status bar (next to
date/time)

colorGreen );
CHANGES FOR VERSION 4.22.0 (as compared to 4.21.1)
* changes made in Indicator Builder are not lost if formula is
incorrect - instead error message is displayed and formula is saved even
if it has a syntax error
* if currently displayed indicator formula has an error - the
error message does not pop up in a separate window but is displayed in
the indicator pane.
* empty indicators are not displayed in the Indicator Builder
and new buttons "Add", "Delete" are provided to add new indicator and
remove existing
* when drawing or moving drawing objects the auto-refresh of the
chart is temporarily held to solve problems with drawing on RT charts.
* Symbol->Information window is not reset every 3 sec when
working with RT data.
* interval between chart updates is now configurable
(Preferences->Intraday)
* Random( seed = none ); function takes new parameter seed.
If seed is defined it initializes the seed of random number generator
this allows to produce repetitive series of pseudo-random series. If
seed is not specified - random number generator continues generation.
To reinitialize the generator, use 1 as the seed argument. Any other
value for seed sets the generator to a random starting point.
Example 1:
Graph0 = Random(); // generates different sequence with each refresh
Example 2:
Graph0 = Random(1); // generates the same sequence with each refresh
* new AFL function
PlotShapes( shape, color, layer = 0, yposition = graph0 );
that allows to plot arrows and other shapes on any chart.
Parameters:
o shape defines type of the symbol. when shape is zero nothing is
plotted
values other than zero cause plotting various pre-defined shapes.
Odd values plot shape BELOW indicator, even values plot shape ABOVE
indicator.
o color defines color of shape
o layer defines layer number on which shapes are plotted
o yposition defines Y-position where shapes are plotted (by
default they are plotted 'around' graph0 (first indicator) line)
Currently defined shapes are

)/ref( array, -periods )
if absmode = True the value returned is array - ref( array, -periods
)/abs( ref( array, -periods ) )
* QuoteTracker plugin now accepts also . (dot) as a date
separator

On second thought there is probably a way, though not particularly
elegant..... :)

Thanks Jayson,
I thought that was the case but I wanted to check with someone more
knowledgeable. I was just trying to have a different background color
for a particular indicator window.
Cheers,
Anthony

Subject: TJ - Charting (PLEASE)
Have tried this a couple of times. Can you please reply..
Ta

Few questions re charting please:
When I switch from daily to weekly view, I only get date markers for APR and
JUL. OCT pops in and out at the right edge as I scroll. Can this be improved
so that for eg, OCT is displayed consistently?
Currently I cannot place default dotted line as vertical month marker
(grid). Are you planning to add this feature?
Also the vertical year markers (grid) plot OVER the 'stylebar' bars which
gives the coincident bar a strange dotted appearance and makes it hard to
see. Can this be fixed so bars plot over the marker (grid)?
Thanks
tL
