Bob,
Parameter info is a tooltip that appears after you type
function name and opening
brace.
So this change means that MarketID param info now displays
MarketID( mode = 0 )
instead of MarketID( range = 0 ) and matches the reference
at:
<A
href="">http://www.amibroker.com/guide/afl/afl_view.php?name=MARKETID
The "misalignment" you mention is not related to / caused
by AmiBroker.
These assignments are build by QP2 plugin and if any
change
is necessary than it needs to be done inside QP2 PLUGIN,
therefore beta
could not address that.
Best regards,Tomasz

AmiBroker 4.29.8 Beta Read Me
March 4, 2003 21:57
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 4.29.8 beta" written in the
About box.
CHANGES FOR VERSION
4.29.8 (as compared to 4.29.7)
updated param info
for LastValue, MarketID, GroupID, SectorID, IndustryID to match the AFL
reference
decreased delay time
for baloon tooltip (status bar area)
fixed hang of
Windows XP when AmiBroker tried to display the tooltip while AB was
minimized. (cause of crash of WinXP when QT was closed before AB)
infinite numbers are
printed now as {INF}, not-a-numbers are printed as {NAN} by
WriteVal.For example:"1/0 =" + WriteVal((1/0));"0/0 =" +
WriteVal(0/0);"(1/0) / (1/0) =" + WriteVal((1/0)/(1/0));"1 / (1/0)
=" + WriteVal( 1 / ( 1 / 0 ) );"Null =" +WriteVal(Null);
3 new AFL
functions:a) IsNan( x ) - returns a nonzero value (1 or TRUE) if the
argument x is a NaN; otherwise it returns 0 (FALSE). A NaN is
generated when the result of a floating-point operation cannot be
represented in Institute of Electrical and Electronics Engineers (IEEE)
formatExample:IsNan( 0/0 );b) IsFinite( x ) -
IsFinite returns a nonzero value (1 or TRUE) if its argument x is not
infinite, that is, if –INF < x < +INF. It returns 0 (FALSE) if
the argument is infinite or a NaN.Example:IsFinite( 1/0
);c) Nz( x ) - Null (Null/Nan/Infinity) to zeroYou can use
the Nz function to return zero, or another specified value when argument x
is Null or Nan or Infinite. For example, you can use this function to
convert a Null (empty) value to another value and prevent it from
propagating through an expression. If the optional valueifnull argument is
included, then the Nz function will return the value specified by that
argument if the x argument is Null (or Nan or Infinity). You can
use the Nz function as an alternative to the IIf function. Instead
of:varTemp = IIf( IsFinite( (H-L)/(C-L) ), (H-L)/(C-L), 0
);You can write:varTemp = Nz( (H-L)/(C-L) );
added IsNull() function - it is the synonym to IsEmpty()
CHANGES FOR VERSION
4.29.7 (as compared to 4.29.6)
added "ask to save changed data" option to Prefs->Misc page (if it
is unchecked AmiBroker saves data without asking)
Symbol -> WatchList ->Import now accepts all formats of .LST
files from Quotes Plus
fixed crash when backward ref bar number was too high
date axis drawing modified (should address 'missing oct 2001' problem)
fixed crash when using extreme zoom in factors (via Zoom to range) and
scrolling max to the right so only blank area is visible.
added check for neg. # of contracts
Apply in Indicator Builder does not scroll to the top
other minor fixes:
CHANGES FOR VERSION
4.29.6 (as compared to 4.29.5)
WriteVal has now new
parameter 'separator' that controls if the numbershould be formatted
with thousand separator or not:WriteVal( ARRAY, format =
8.3, separator = True )WriteVal( Volume, 8.3, True ); // with
separatorsWriteVal( Volume, 8.3, False ); // without
separators
thousand separator is not added to numbers in AA->Export
thousand separator does not appear when usingAddColumn(
DateTime(), formatDateTime );
fixed inconsistency between AA result line (incorrect) and AA report
(correct) when formula was using SetOption("InitialEquity", nn) to
change the Init. equity set in the AA settings(thanks Herman)
fix: % change is displayed again in RT quote window.
fix: watch list dialog (watch list->remove) does not show lists
above > 32 if given symbol does not belong to given watch list.
new AFL function: GetChartID() allows to retrieve current indicator
chart ID. (returns 0 (zero) in AA window)
other minor fixes
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
functionsBeginValue( 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 formatDateTimeWriteVal( 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 settingsformat = 1 - returns
string containing current date only formatted according to system
settingsformat = 2 - returns string containing current time only
formatted according to system settingsformat = 3 - returns DATENUM
number with current dateformat = 4 - returns TIMENUM number with
current timeformat = 5 - returns DATETIME number with current
date/timeSee: <A
href="">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
SettingsWhen 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 withAddColumn and formatDateTime
constantto produce date time formated according to your system
settingsAddColumn( 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 -1e10obsolete 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:
sorting of text columns is 2 times faster (on average)
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
backgroundAddColumn 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 functionsParam(
"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+Rallows 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
quoteslong 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
4.23.0 (as compared to 4.22.1)
chart axis font can be defined by the user. The default is now 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)
Insert Indicator window (Ctrl+I) does not show empty indicator slots
anymore.
CHANGES FOR VERSION
4.22.1 (as compared to 4.22.0)
fixed overwrite problem occuring when deleting first indicator in the
list in Indicator Builder
fixed shortcut conflict &File and &Format. Now Format menu has

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
refreshExample 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:
shape defines type of the symbol. when shape is zero nothing
is plottedvalues other than zero cause plotting various pre-defined
shapes.Odd values plot shape BELOW indicator, even values plot shape
ABOVE indicator.
color defines color of shape
layer defines layer number on which shapes are plotted
yposition defines Y-position where shapes are plotted (by
default they are plotted 'around' graph0 (first indicator) line)
