d, sorry for the delay... This is not the best example but may
do for starters. I am still playing with it and the display varies
depending on the system's state. I set Blank Bars to the Right of the chart to 2
to give space for text beyond the last bar. Using "\n" I
concatenate various Status msgs I want to see, then display that with
one PlotText(). Typically i would like to know the states of my next trade or
the trade in progress: qualifiers, stops and limits, etc. Global system
status is displayed in the title, not shown here. I trade 1 minute RT.
I sure find it easier to trade having all relevant information
around the last bar...
best regards,
herman

Hi Chuck,
Normally i display Trading and System
stats (Recent Trades, Equity, Critical Param, etc. ) in table format in the
Chart Title. I also displayed there action information on the current trade,
such as various levels of Trade entry, partials fills, order status, etc. I know
you can use the interpretation screen for this but i prefer all the "action" in
one window. The problem is that in Real-Time trading the tile is far removed
from the action at the last bar and one tends to miss events because of the
continual refocusing that is required.
The new PlotText() allows me to
show all the "action" information right above/below the last bar in nice colors,
now I only have to pay attention to a few square inches of the chart during
trading, instead of two opposite corners of the monitor. Much more relaxing, no
more eye fatigue :-)
best regards,
herman

Thank
you Tomasz, some great new features!
I love the PlotText and i am already
working on code to move trade-stats from the Title to the RT bar. Also, now RT
trading information can be placed right at the last bar for easy viewing. Good
stuff!!!

CHANGE LOG
CHANGES FOR VERSION 4.77.0 (as
compared to 4.76.0)
styleDashed now uses correct background color when it is
modified using SetChartBkColor
AFL Editor: when there is nothing more
to undo/redo beep sound is produced
AFL: OBV() and AccDist() now work
correctly with TimeFrameSet (#26768)
AFL Editor: Edit->Replace
implemented (Ctrl+H shortcut)
CBT: AddCustomMetric now has new
parameter that controls number of decimal places used to display custom
metric
Trade.AddCustomMetric( "Name", value, [optional] decplaces = 2
);
Backtester.AddCustomMetric( "Name", Value, [optional] LongOnlyValue =
Null, [optional] ShortOnlyValue = Null, [optional] decplaces = 2
);
where
decplaces defines how many decimal places are used to display
given metric in the report.If not specified it defaults to 2 decimal
places.
Example code:
bo.AddCustomMetric( "Somestat", 100*kr,
Null, Null, 4 ); // 5th parameter controls number of decimal
places
Tooltip "value" field now uses Prefs setting
(Tools->Preferences->Misc: "Decimal places in chart titles/tools") + 1
digit decimal points
All Fibonbacci tools now use user-defined number
of decimal places (Tools->Preferences->Misc: "Decimal places in chart
titles/tools").
Note that this setting applies to NEWLY drawn or MODIFIED
fibonacci retracements. Already existing ones won't be affected until you
modify/move them.
Added new submenu under "Symbol": "Real Time Quote"
with 3 new options: Add selected symbol / Add watch list / Remove all
symbols
IMPORTANT NOTE: to see new menu you need to go to
Tools->Customize, select "MENU" bar and press "RESET" button
AFL:
PlotText("Text", x, y, color, bkcolor = colorDefault )
New AFL
function:
PlotText( "text", x, y, color, bkcolor = colorDefault
)
Writes text in specified co-ordinates
where
x - is
x-coordinate in bars (like in LineArray)
y - is y-coordinate in
dollars
color is text color
bkcolor is background color
If
bkcolor is NOT specified (or equal to colorDefault) text is written with
TRANSPARENT background
any other value causes solid background with specified
background color
Example:
Plot(C,"Price", colorBlack, styleLine
);
Plot(MA(C,20),"MA20", colorRed );
Buy=Cross( C, MA(C,20 )
);
Sell= Cross( MA( C, 20 ), C );
dist = 1.5*ATR(10);
for( i =
0; i < BarCount; i++ )
{
if( Buy[i] ) PlotText( "Buy\n@" + C[ i ], i,
L[ i ]-dist[i], colorGreen );
if( Sell[i] ) PlotText( "Sell\n@" + C[ i ], i,
H[ i ]+dist[i], colorRed, colorYellow );
}
PlotShapes( Buy *
shapeUpArrow + Sell * shapeDownArrow, IIf( Buy, colorGreen, colorRed )
);
AFL: VarGetText
New function
VarGetText( "varname"
)
the same as VarGet but always returns always string values
(if
underlying variable has different type it is converted to string)
Allows
for example appending to text variable no matter if it is defined earlier or
not:
Title = VarGetText("Title") + "something"; // this will work
correctly regardless of whenever title was defined earlier or
not]
VarSetText
New function
VarSetText( "varname", "value"
)
the same as VarSet but operates on string
values.
Auto-analysis backtest result summary modified (added row
count and removed wordwrap)
Enlarged "Additional commands" field in
ASCII Import Wizard
CBT: Fixed "Out of range" message generated by
OLE wrappers when GetValue method of CBT Metrics object returned infinite value
(for example as result of division by zero)
Fixed handling of CLICK -
DRAW - CLICK drawing mode (#26994) during RT refresh
Fixed incorrect
candle color occuring sometimes when candle body was only 1-pixel
high
Fixed potential crash occuring sometimes when RTQ window was
never shown but RT update arrived
Fixed problem with double arrows
appearing on chart with ID == 1
Fixed problem with selected date in
Print/PrintPreview/Image copy
RTQ context menu "Delete symbol"
renamed to "Remove symbol"
UI: simplification, Removed (default) from
File->Database Settings Base Time interval Combo and "(default)" from local
data storage and removed "IMPORTANT ..." static
CHANGES FOR VERSION
4.76.0 (as compared to 4.75.2)
Renamed "Number of bars to load" to just
"Number of bars"
Fixed problem with weird Time&sales background
colors (bug introduced in 4.75.x)
Fixed 1.#INF in P/E colum (RT quote
window)
Editor: fixed actionBacktest / actionExplore mix in
auto-complete dropdown
Chart Y-axis can now be displayed as fractions
(1/4, 1/8, 1/16, 1/32, 1/64, 1/128) - to switch this use Parameters -> GRID
-> FORMAT
CBT: Trade object has now "Handle" property that can be
passed to ExitTrade and ScaleTrade methods instead of symbol to allow control
over exiting/scaling multiple positions of the same symbol
// This is
sample formula that allows
// to open multiple, separate positions on the
same symbol
// without averaging effect (i.e. each position on the same
//
symbol is completely independent).
//
// Sample code is provided for
trading one symbol
// Enter symbol you want to trade below
Symbol =
"MSFT";
Buy=Sell=Short=Cover=0; // real rules are defined inside custom
backtest proc
SetCustomBacktestProc(""); // enable custom
backtest
if( Status("action") == actionPortfolio )
{
// actual backtest routine
// (low-level)
bo
= GetBacktesterObject();
SetForeign( Symbol
);
// make sure to calculate actual buy and buyprice arrays for
symbol we need to backtest
Buy = 1; // For testing purposes just
enter new position every bar
BuyPrice = Open;
RestorePriceArrays();
// actual backtest
loop
bo.PreProcess();
for( i = 1; i <
BarCount; i++ )
{
// first
update backtest stats and handle stops
bo.UpdateStats( i, 0 );
bo.HandleStops(
i );
bo.RawTextOutput("Bar " + i );
if( Buy[ i - 1
] ) // if buy signal in previous bar
{
bo.EnterTrade( i, Symbol,
True, BuyPrice[ i ], 500 /* $5000 into one trade
*/);
}
for( OpenPos =
bo.GetFirstOpenPos(); OpenPos; OpenPos = bo.GetNextOpenPos()
)
{
// exit
positions if their age is > 5 bars and they are
profitable
if(
OpenPos.BarsInTrade > 5 AND OpenPos.GetProfit() > 0
)
{
// HERE
IS A NEW PART
!!!
// WE
ARE PASSING HANDLE instead of ticker
symbol
//
THIS ENSURES PROPER OPERATION even if we have multiple positions of the
same
//
stock
bo.ExitTrade( i, OpenPos.Handle, OpenPos.GetPrice( i, "O" )
);
}
}
bo.RawTextOutput("Number of open
positions: " + bo.GetOpenPosQty()
);
bo.UpdateStats( i, 2
);
}
bo.PostProcess();
}
CBT: Small fix for low-level CBT backtest -
internal current bar counter is set now via UpdateStats
ASCII import
wizard: Additional commands field accepts "ENTER" key alone (previously one
needed CTRL+ENTER to create new line)
ASCII importer limits the
volume to 2147483647 so after convertion to 32bit integer it never becomes
negative
Added parameter list to backtest report (Settings
page)
CHANGES FOR VERSION 4.75.2 (as compared to 4.75.1)
when no data
we available chart background is correct now (it was black instead of one
choosen in prefs in 4.75.x)
Added ability to disable fixed ruin
stop
When you add
SetOption("DisableRuinStop", True);
to your
formula the backtester will not use built in 99.96% loss stop (ruin) Note: it is
recommended NOT to use it unless you really have to.
added new option
to SetOption:
SetOption("EveryBarNullCheck",
True)
SetOption("EveryBarNullCheck", True)- allows to turn on checking
for Nulls in arithmetic operations on every bar in the array(by default it is
OFF - i.e. AmiBroker checks for nulls that appear in the beginning of the
arrayand in the end of the array and once non-null value is detected it assumes
no further holes (nulls) in the middle). Turning "EveryBarNullCheck" to True
allows to extend these checks to each and every barwhich is the way 4.74.x and
earlier versions worked.
Note however that turning it on gives huge
performance penalty (arithmetic operations are performed even 4x slower when
this option is ON, so don't use it unless you really have to).
Added
small result summary after backtest in the status line
Fixed problem
with plotting xshifted charts occuring when formula referenced future
bars
logical (boolean) operators check for nulls on every bar and
treat null as "false" to maintain backward compatibility with formulas written
for previous versions
Modified file dialog buffer size from 262144
(0x40000) bytes to 262143 (0x3FFFF) to workaround 16 bit (64KB) buffer limit of
Windows 95/98/NT4 (yes surprisingly NT4 is limited to 64K buffer in file
dialogs)
16-bit windows (95/98) and NT4 were treating 0x40000 as 0 (zero)
because only lower 16 bits were interpreted. Thanks to move to 0x3FFFF it is now
interpreted as 0xFFFF on 16 bit windows.
Potential crash fixed when
formula using AddToComposite atcEnableInBacktest is verified in the AFL
editor
Added XShift parameter to PlotOHLC and PlotForeign
functions
fixed re-mapping of built-in and custom colors in grid
color picker
CHANGES FOR VERSION 4.75.1 (as compared to
4.75.0)
ParamColor now accepts 24 bit colors without crashing
Null
values appearing at the end of data series (array) are handled appropriately
(propagate through arithmetic operators)
This fixes problem that 4.75.0 had
with "trendline" formulas that used Null values put into the array at the end of
the data series.
Most recently picked drawing tool color is preserved
between runs
EncodeColor was not handling all 24 bit color
combinations correctly. Fixed now.
Chart tree fix: Moving or renaming
formula in charts tree now updates all paths in indicators that use this
formula
CHANGES FOR VERSION 4.75.0 (as compared to 4.74.6)
New
chart style (styleCloud) to be used to create "cloud" chart as in Ichimoku
charts. Also useful for indicator charts like MACD.
This style fills
non-rectangular (free shaped) area between HIGH and LOW arrays provided
by
PlotOHLC function. Open and Close arrays are not relevant for plotting however
Close
is used as usual to display value label and title. So recommended use
is to use "upper" bounding value
in Open and High arrays and "lower" bounding
value in "Low" and "Close" arrays
Sample Ichimoku cloud:
SL = ( HHV( H, 26
) + LLV( L, 26) )/2;
TL = ( HHV( H, 9 ) + LLV( L, 9 ) )/2;
DL = Ref( C, 25
);
Span1 = Ref( ( SL + TL )/2, -25 );
Span2 = Ref( (HHV( H, 52) + LLV(L,
52))/2, -25);
Plot( C, "Price", colorBlack, styleCandle );
Plot(
SL, "SL", colorRed, styleThick );
Plot( TL, "TL", colorGreen, styleThick
);
PlotOHLC( 0, span1, span2, span2, "Cloud", colorLightOrange, styleCloud
);
Simple MACD cloud:
m = MACD();
Plot( Signal(), "Signal", colorBlue,
styleThick );
PlotOHLC( m,m,0,m, "MACD", IIf( m > 0, colorGreen, colorRed
), styleCloud );
Another MACD cloud (difference):
m = MACD();
s =
Signal();
Plot( s, "Signal", colorBlue);
Plot( m, "MACD", colorRed
);
PlotOHLC( m,m,s,m, "MACD", IIf( m > s, colorLime, colorLightOrange),
styleCloud );
when File->Open database or MRU list is choosen then old
database is saved first
When default database is deleted, AB now asks
for new default database folder, instead of re-creating it
when
database is deleted from the outside and user picks it via MRU list -then gets
removed from MRU list and is not recreated anymore
When AmiBroker is
launched with incorrect "Start in" (working directory) then it automatically
switches to "last good" path
" Last good" path is saved in the registry
HKEY_CURRENT_USER\TJP\Broker\Defaults\LastGoodPath, during successful launch in
correct directory (whenever working directory is correct or not it is determined
by checking for presence of Broker.chm file (help file))
Using correct
working directory is important because AmiBroker uses relative paths to most
components.
AFL: new function:
StaticVarRemove()
StaticVarRemove("varname")
removes static variable
and releases associated memory
Start-up time decreased significantly
by implementation of on-demand loading of formulas
(on slow, low-end
machines loading time decreases from 10 seconds to just 0.5
second)
printf/StrFormat/SelectedValue functions no longer affect
number of extra future bars calculated by QuickAFL
Minor plugin
status change (as in IB backfill) does not cause sound (only tooltip is
displayed)
Increased the limit of files that can be selected using
Windows file dialog
Now import wizard and ascii importer file dialogs use
256KB buffer for file names that on average should allow 20000 files to be
selected at once.
Further speed improvements by rewriting chart ID
lookup routine (GetChartInfoByID)
Chart title string is clipped so Y
axis is never obscured
Chart title can be automatically wrapped
now
Use 'Parameters' window,
" Axes & Grid"
tab,
Miscellaneous->Wrap title: YES
If you want to set it
programmatically from the formula use
SetChartOptions( 2, chartWrapTitle
);
Auto-hide panes slide slightly faster
All basic array
arithmetic and logical operators inlined and hand optimized on assembly level
for speed, gives upto 450% speed increase in basic array
calculations
Example speed increases:
a) purely "theoretical"
example
million iterations of array addition
for( i = 0; i < 1000; i++
)
for( k = 0; k < 1000; k++ )
Sumh = H +
L;
runs 4.8 times (+480%) faster (5 seconds in 4.75 compared to 24
seconds in 4.74 and older, Athlon64@xxxx)
2000 data bars.
This gives (
2000 * 1000000 additions ) / 5 sec = 400 MEGAFLOPS (millions of floating point
operations per second) AFL array-based AFL execution speed.
b)
"real-world" examples:
" Projection Oscillator"
http://www.amibroker.com/library/detail.php?id=344
single
security optimization runs 85% faster
(13 seconds (4.75) compared to 24
seconds (4.74 or older) )
" RSIS"
http://www.amibroker.com/library/detail.php?id=153
single-security
optimization 5000 iterations runs 21% faster
(28 seconds (4.75) compared to
34 seconds (4.74 or older))
NOTE: Performance increase depends on
complexity of the formula. Biggest gains can be observed for formula doing LOTS
of mathematical calculations on arrays (using lots of +, -, *, /, ^, %,
comparisions <, >, ==, !=, <=, >=, etc).
AFL: new
function: SetChartBkColor( color )
sets chart background to user-specified
color
Added View->Time & Sales menu back
Added
chart timing display (you can turn it on via Tools->Preferences->Display
chart timing)
when turned on, in the bottom of each chart the following
information is displayed:
Total time X sec, AFL exec time Y sec (Z %), #
extra bars back Q, fwd R
where
X - is total time in second spent
during chart refresh ( this includes AFL execution and actual screen
painting/drawing, grid / scale calculations, etc)
Y - is time spent in chart
AFL execution only (without any actual screen painting, grid / scale calcs)
Z
- is percentage of time that AFL execution takes compared to total time required
for refresh
Q - is a number of previous bars (before first visible bar) that
are needed to calculate the indicator (QuickAFL estimation)
R - is the number
of future bars (after last visible bar) that are needed to calculate the
indicator (QuickAFL estimation)
Added asin/acos to the AFL function
reference
AFL: 24-bit (16 million) truecolor support for indicators
and exploration output.
new ColorRGB() and ColorHSB functions to
access full 24 bit palette
ColorRGB( red, green, blue )
returns
color value to be used in Plot/PlotOHLC/AddColumn/AddTextColumn
red, green,
blue - represent color component values in range 0..255 each
For more
information about RGB color model please read:
http://en.wikipedia.org/wiki/RGB_color_model
ColorHSB(
hue, saturation, brightness )
returns color value to be used in
Plot/PlotOHLC/AddColumn/AddTextColumn
hue - represents gradation of color
within the optical spectrum (as in rainbow)
saturation represents "vibrancy"
of the color
brightness represents brightness.
Each parameter ranges
from 0 to 255, where 0 represents 0% saturation/brightness
or 0 degree hue in
HSV color wheel,
and 255 represents 100% saturation/brightness or 360degrees
hue in HSV color wheel
When you modify hue from 0 to 255 you will see
consecutive
rainbow colors starting from red, through yellow and green to
blue and violet.
For more information about HSB color space please
read:
http://en.wikipedia.org/wiki/HSB_color_space

customizations made in old versions need to be re-done because they can not be
imported by new system due to fundamental differences (I am sorry about
that)]
GroupID(), IndustryID(), SectorID, MarketID(), InWatchList(),
IsIndex() and IsContinuous() functions are now affected by
SetForeign
Removed debug messages cluttering DebugView output (that
appeared in 4.73)
Changed the way drawing color picker is working:
now it works like in Word (or other text editor) - keeps selected color even if
drawing with different color is clicke
Fixed false message "The note
has been modified outside the notepad editor." occuring when file did not
exist
OLE: Changed Window.LoadTemplate to return FALSE when file can
not be found
OLE: Window.LoadTemplate now refreshes display so it is
not necessary to use SelectedTab = 0
Removed constant RT refreshes in
interpretation window when text does not change
ZoomToRange: last
selected bar in range is visible after zooming now
CHANGES FOR VERSION 4.73.0
(as compared to 4.72.1)
OLE: Window object, new method ZoomToRange( From, To
)
ZoomToRange( From, To )
From and To parameters are of any type that can
be converted to date(you can use string or OLE date for example).
Example
code (JScript):
AB=new ActiveXObject("Broker.Application");
AW =
AB.ActiveWindow;
if( AW.ZoomToRange( "2005-04-01", "2005-08-01" )
)
{
WScript.Echo("Zoom successfull" );
}
Fixed:
Chart got shrinked a bit with each overlaid plot, now the Y scale does not
change (unless really needed)
Fixed: XShift now works correctly with
styleOwnScale and styleLeftScale
Fixed: Volume chart overlaid on
price chart in log scale (overlay) was compressed to flat line, now it is fixed
(volume chart overlay uses linear scale always)
[#22262]
AFL:
Added AlmostEqual function (completed: 2005-09-16)
AlmostEqual( x, y,
ulps = 5 )
this is a helper function for comparing floating point
numbers.It returns True if x and y are equal or almost equal upto defined
accurracy (ulps).It is recommended to use this function instead of equality
check (==) as itleads to more reliable comparisons and less headache caused by
IEEE floating pointacurracy issues.
Parameters:x, y - the numbers or
arrays to be compared,Ulps stands for "units in last place" and represents
maximum relative error of the comparison. Since 32 bit IEEE floating point
numbers have accurracy of 7 significant digits, 1 unit in last place(ulp)
represents relative error of 0.00001 %. The default value of ulps parameter is 5
which gives roughtly 0.00005% "comparison sensitivity".
Example
code:
if( 1/3 == 0.3333333 )
{
printf("32-bit Floating point
IEEE exact equality\n");
}
if( AlmostEqual( 1/3, 0.3333333 )
)
{
printf("Numbers are almost equal\n");
}
Thanks to
Bruce Dawson for his fast routine.
Optimize() function now checks if
min < max, step > 0 and checks if parameter name is not
empty
Made Time&Sales case insensitive (when "case sensitive
tickers" option is turned off")
OBV/AccDist/Chaikin functions
adjusted to be SetForeign-aware
OLE: Application object new
methods
BOOL LoadLayout( filename )
BOOL SaveLayout( filename )
AB
= new ActiveXObject("Broker.Application");
AB.LoadLayout("C:\\Program
Files\\AmiBroker\\Data\\Layouts\\Default.awl");
OLE: Window object
new property: SelectedTab
AB = new
ActiveXObject("Broker.Application");
AW = AB.ActiveWindow;
tabindex =
AW.SelectedTab; // read selected tab
AW.SelectedTab = 3; //switch to tab
3
AW.SelectedTab = tabindex; // restore originally selected
tab
Fixed: Exception was generated when GetRTDataForeign was called
with non-existing ticker
OLE: Window object new methods:
LoadTemplate, SaveTemplate
AB = new
ActiveXObject("Broker.Application");
AW =
AB.ActiveWindow;
AW.SaveTemplate("Test.abt");
AW.LoadTemplate("Test.abt");
CHANGES
FOR VERSION 4.72.1 (as compared to 4.72.0)
fixed out-of-memory problem
sometimes occuring during scan of large (>512MB) databases
CHANGES FOR
VERSION 4.72.0 (as compared to 4.71.1)
" Currency" field support in ASCII
importer
added command:
$CURRENCY USD
and field:
$FORMAT
Name,Currency$OVERWRITE 1$AUTOADD 1]
Added "Additional commands"
field in the Import wizard for typing any extra $- commands that are not
available via checkboxes
Added parameter to AddColumn/AddTextColumn
to control column width
AddColumn( ARRAY, "Caption", format = 1.2, color
= colorDefault, bgcolor = colorDefault, width = -1);
AddTextColumn( "Text",
"Caption", format = 1.2, color = colorDefault, bgcolor = colorDefault, width =
-1 );
AddToComposte new flag to work when Status("action")==
actionPortfolio (completed: 2005-09-09)
new flag is called
atcEnableInPortfolio
Example:
if( Status("action" ) ==
actionPortfolio )
{
... Custom backtest mode here
....
AddToComposite( some_array, "~COMPOSITE", "X", atcFlagEnableInPortfolio
| atcFlagDefaults );
}
AFL added: tanh(), sinh(), cosh()
functions
Hyperbolic tangent, sine and cosine function
AFL
functions: StrToUpper and StrToLower
Fixed: Tick ASCII import: last
tick of previous import was deleted on subsequent import, now it is
corrected
Function to detect mouse button
state
GetCursorMouseButtons() returns mouse button state at the time when
chart formula is executed
0 - if no mouse button is pressed
1 - if
left mouse button is pressed
2 - if right mouse button is pressed
4 - if
middle mouse button is pressed
plus combinations:3 - left + right5 - left
+ middle6 - right + middle 7 - left + right +
middle]
GetRTDataForeign (retrieving values for other
symbols)
GetRTDataForeign( "field", "symbol")
Pane is not deleted
if shrinked down to zero (prevents from accidential deletion of
panes)
Plot function now has xshift parameter that allows to visually
shift the chart past the last bar
Example 20-bar Moving average shifted 10
bars into the future past the last
bar:
Plot(Close,"Close",colorBlack,styleCandle);Plot(MA(Close,20),
"Shifted MA", colorRed, styleLine, Null, Null, 10 );
Note that shift
occurs during plotting and does not affect source array
Removed data
source selection from preferences because it caused user confusion way too
often
Stock.Currency available via OLE
Title variable now
supports new special token {{OHLCX}} which is replaced at runtime by string
"Open ..., Hi .... Lo ... Close (...%)" showing current price
This way it
is possible to implement formula that will show OHLC prices with number of
decimal places set in the
preferences.
Example:
SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title
= "{{NAME}} - {{INTERVAL}} {{DATE}} {{OHLCX}} {{VALUES}}" );
Plot( C,
"Close", ParamColor("Color", colorBlack ), styleNoTitle | ParamStyle("Style") |
GetPriceStyle() );
user-definable number of decimal places in chart
titles (completed: 2005-09-09)
Number of decimal places displayed in default
chart title is now user-definable
inTools->Preferences->Miscellaneous"Decimal places in chart
titles".
Allowable values:
-1 - dynamic mode (number of decimal places
automatically adjusted)
0..6 - fixed number of decimal
places
QuoteArray resizing now uses heuristic algorithm to minimize
memory fragmentation and increase performance
atcFlagDeleteValues now
highlighted properly in the AFL editor
CHANGES FOR VERSION 4.71.1 (as
compared to 4.71.0)
fixed compatibility problem with AmiQuote (due to changed
order of OLE properties/method while AmiQuote was using old ones)
now ASCII
importer in $TICKMODE does not delete quotes older than oldest (first) record in
the imported file, so you can safely import tick data from subsequent files
(older first, newest later)
CHANGES FOR VERSION 4.71.0 (as compared to
4.70.5)
AFL: added GetCursorXPosition() and GetCursorYPosition()
functions
Functions return current mouse cursor position.
Values
returned are equal to those visible in the status bar, and these functions
require status bar to be visible. Returned values represent cursor position at
the formula execution time (or few milliseconds before it) and accurracy is
subject to pixel resolution of the screen (first cursor position is read in
screen pixels (integer) and then converted to actual value therefore for example
when screen resolution is 1024x768 maximum obtainable resolution in X direction
is 0.1% and in Y direction 0.13%), also X values are snap to datetime of nearest
data bar.
It only makes sense to use these functions in
indicator/interpretation code.
Using them in AA window may yield random
values.GetCursorXPosition() function returns X position in DateTime format (the
same as used by DateTime() function).You can convert it to string using
DateTimeToStr() function.GetCursorYPosition() returns Y position (as displayed
in Y axis of the
chart).
Example:
ToolTip="X="+DateTimeToStr(GetCursorXPosition())
+"\nY="+GetCursorYPosition();
AFL: added DateTimeToStr() and StrToDateTime()
functions
These functions allow to convert string to datetime format and
vice
versa.
Example:
ToolTip="X="+DateTimeToStr(GetCursorXPosition())
+"\nY="+GetCursorYPosition();]
Added ability to store charts as .GIF (in
addition to PNG)
ASCII importer maximum supported line length is increased to
2048 characters
Fixed: .aflsafe files didn't get deleted
automatically
Added N-volume bars charts and timeframe support.
Custom
N-volume bar intervals are definable (as usual) in
Tools->Preferences->Intraday.
TimeFrame functions were also
extended to support N-volume bars using new TimeFrameMode() function
calling
TimeFrameMode( 0 );
- switches time frame functions to
time-based operation (the default)
TimeFrameMode( 1 );
- switches
time frame functions to N-tick operation (positive values passed to TimeFrameSet
are treated now as N-tick)
TimeFrameMode( 2 );
- switches time
frame functions to N-volume bar operation (positive values passed to
TimeFrameSet are treated nowas N-volme
bars)
Example:
TimeFrameMode( 2 );
TimeFrameSet( 50000 ); //
50'000 share bars..
...do something ...
TimeFrameRestore();
Note:
N-volume bars are somewhat weird (compression of data to N-volume bar may
actually deliver MORE output bars - for example if one tick is 1000 shares and
you have specified 100V bars then single tick will be expanded to TEN 100V bars
- ten times original size)
TimeFrame functions are protected against array
overrun and will not decompress beyond original array size (you will get an
"Error 47. N-volume bar compressed data longer than base time frame").
Also
switching main time frame to some weird N-volume bar value will result in
limiting the output to maximum twice original data size(without error
message).
You should keep that in mind and avoid using too small N-volume bar
intervals that could lead to such condition.
Also due to the nature of
N-volume bars the only TimeFrameSet() function will yield correct N-volume bar
values, TimeFrameGetPrice() may give slightly distorted results.
It is also
possible to use n-volume bars in TimeFrame functions without calling
TimeFrameMode() - it is then necessary to specify n-volume bars as negative
number offset by -1000000 (minus one million):
TimeFrameSet( -1000000 -
2000 );
// gives 2000V barsSimilarly formatted negative numbers will be
reported by Interval() function when n-volume bars are selected.
OLE:
Save As PNG / GIF callable from automation
Example script:
AB =
new
ActiveXObject("Broker.Application");
AB.ActiveWindow.ExportImage("Test.png");
Plugin
is not called when GetExtraData is used for symbol that has "use only local
database" flag turned on, and NULL is returned instead of an error
Protected
against changing application's current working directory by printing to
file
Toolbar does not get wrapped when main frame window is resized
OLE:
Analysis object has new method MoveWindow( x, y, width, height) that allows to
control position and size of automatic analysis window
AB = new
ActiveXObject("Broker.Application");
AB.Analysis.MoveWindow( 10, 10, 200, 200
);
It has some restrictions on size: specified size can not besmaller
than 10x10 pixels and can not be bigger than entire screen dimensions.
Also
when "No minimum size for resizing dialogs" box in UNCHECKED in
Tools->Prefs->Misc it won't shink AA window below default size necessary
to fully display all controls.
ASCII importer: added ability to import tick
data from text files
ASCII importer now allows tick data files to be
imported.
Tick data files consist of several records having the same
timestamp.This makes it impossible to use normal import mode which assumes
different (unique) timestampsfor each data row (when same timestamp is found
then new data overwrites old).
To turn on TICK mode you need to add
manually
$TICKMODE 1
line to ASCII importer definition
file.
$TICKMODE is a special mode of importer that allows to import
quotes that haveduplicate time stamps.
It makes two assumptions:
a)
input data should come in the ascending time order (i.e. OLDER records first,
LATEST records last)
b) input data should consist of entire tick history
because importer will DELETE any existing quotes (to avoid creating multiple
copies of the same ticks).
Once again: Turning on
$TICKMODE 1
will
DELETE ANY QUOTES that already exist in the database and then will import all
ticks from input data file.
You have been warned.
For example data
files like
this:
MOL,0,20050606,162959,16400.0000,16400.0000,16400.0000,16400.0000,2MOL,0,20050606,162959,16400.0000,16400.0000,16400.0000,16400.0000,11MOL,0,20050606,162959,16400.0000,16400.0000,16400.0000,16400.0000,40
Can
be imported using the following definition file:
$FORMAT Ticker, Skip,
Date_YMD, Time, Open, High, Low, Close, Volume
$SKIPLINES 1
$SEPARATOR
,
$CONT 1
$GROUP 255
$AUTOADD 1
$DEBUG 1
$TICKMODE
1
Sometimes it happens that input files have invalid timestamps (seconds
> 59).
For
example:
MOL,0,20050606,162970,16400.0000,16400.0000,16400.0000,16400.0000,2
Please
take a closer look at first line shown in this example it has time:16:29:70 (you
see 70 seconds !)
So I had to add a special flag to the importer that works
around such data errors.
It is called $ALLOW99SECONDS 1 and will convert
all records with invalid seconds (i.e greater than 59)to 59s.
So record
stamped 16:29:70 will be treated as 16:29:59
Now for tick mode to work with
such incorrect records you would need to add two lines to ASCII importer
definition:
$TICKMODE 1
$ALLOW99SECONDS 1
