CHANGE LOG
CHANGES FOR VERSION 4.52.0 (as compared to 4.51.1)
fixed problem with fixup=0 and handling multiple data holes in a row
added new commands to ASCII format definitions:$MINTICKERLEN
<number> - defines minimum accepted length of the ticker
symbol$MAXTICKERLEN <number> - defines maximum accepted length of
the ticker symbol For example ASX users may wish to use$MAXTICKERLEN
3to make sure that ASCII importer accepts only symbols that have no more
than 3 characters (this excludes ASX options and warrants)
fixed problem with incorrect very first value of the array returned by
variable-period version of HHV/LLV
fixed Procedure/function parameter overwrite issue when using built-in
price arrays and variable overwrite issue
memory allocated for return value is marked for earlier freeing so calling
user-defined functions inside loops should consume less memory
Interval() function enhanced. Now accepts format parameter:Interval(
format = 0 );possible values:format = 0 - returns bar interval in
secondsformat = 1 - as above plus TICK bar intervals are returned with
negative signso Interval() function applied to 10 tick chart will return
-10format = 2 - returns STRING with name of interval such as
"weekly/monthly/daily/hourly/15-minute/5-tick"
vertical quote selection line in linked windows is now independent
changing "same day stops" via SetOption("SameDayStops") in portfolio
backtest mode has an effect now (previously reacted only on manual
settings)
SetOption("CommissionMode", mode ) works now in portfolio mode too
(previously workedin old backtest mode only)
SetOption("CommissionAmount", amount ) works now in portfolio mode too
(previously workedin old backtest mode only)
$SEPARATOR command in ASCII importer definitions now allows to import
files that have fields separated by more than one separator characters
Separator string (array of characters) must be enclosed in quotation marks. If
there is only one separator character (as in old versions) then quotation
marks are needed.For example files with joined date and
time$SEPARATOR ", "$FORMAT
DATE_YMD,TIME,OPEN,HIGH,LOW,CLOSEwill be able to import file like
this:2004-02-04 12:30,3.41,3.44,3.40,3.42 (note date and time field
are separated by space not by comma)
Import wizard now supports new separators 'comma or space', 'semicolon or
space' and 'tab or space'
ASCII importer and Quote Editor properly distinguish records with time
specified as 00:00:00 from EOD records (without time)
CHANGES FOR VERSION 4.51.1 (as compared to 4.51.0)
OLE interface methods numbering adjusted to maintain backward
compatibility with previous versions and other programs referring to old OLE
interface
CHANGES FOR VERSION 4.51.0 (as compared to 4.50.10)
OLE automation interface changes:
Analysis.Backtest and Analysis.Optimize now support new "Type"
parameter.Type can be one of the following values:0 : portfolio
backtest/optimize1 : individual backtest/optimize2 : old
backtest/optimizeFor backward compatibility Type parameter is optional
and defaults to 2(old backtest/optimize)
Example code:AB = new
ActiveXObject("Broker.Application");AB.Analysis.Backtest( 0 ); // perform
portfolio backtestAB.Analysis.Optimize( 0 ); // perform portfolio
optimize
OLE automation interface new object: "Commentary"This object has 5
methods:- BOOL LoadFormula( STRING pszFileName ) - loads the formula-
BOOL SaveFormula( STRING pszFileName ) - saves the formula- void Apply() -
displays the commentary - BOOL Save( STRING pszFileName ); - saves
commentary output (result) to the file (use after call to Apply())- void
Close() - closes the commentary window
Commentary object is accessible from Broker.Application object via
Commentary property:
Example code:AB = new
ActiveXObject("Broker.Application");AB.Commentary.LoadFormula("C:\\Program
Files\\AmiBroker\\AFL\\MACD_c.afl");AB.Commentary.Apply();AB.Commentary.Save("Test.txt");AB.Commentary.SaveFormula("MACDTest.afl");//AB.Commentary.Close();
AFL function Now( format = 0 ) accepts new parameter values
Returns current date / time in numerous of formats: // formats
supported by old versionsformat = 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

colorRed ); // NOTE that this plot name/value will NOT appear in the
titlePlot( MA( C, 20 ), "MA20", colorGreen );
