CHANGE LOG
CHANGES FOR VERSION 4.54.0 (as compared to 4.53.1)
"Allow mixed EOD/intraday data" mode added (controllable from
File->Database Settings->Intraday, checkbox with the same name) it
allows to work with database that has a mixture of intraday and EOD data in
one data file. If this is turned on then in intraday modes EOD bars are
removed on-the-fly and in daily mode EOD bars are displayed instead of time
compressed intraday or if there is no EOD bar for corresponding day then
intraday bars are compressed as usual.
This mode works in conjunction with new versions of plugins that allow
mixed data. Mixed mode is now supported by MarketCast plugin (1.1 or
higher)(Australia) and eSignal plugin (1.7.0 or higher) only.
Mixed mode allows intraday plus very long daily histories in one
database.
Note that this is EXPERIMENTAL feature.
+ Real-Time quote window enhancedNow only fields that are changed
change the background to 'yellow' and if the value in given field increases
then it is displayed in green if decreases then is displayed in red. This
allows easy identification of movement.
+ all strings in the program moved to resources for easy localization
+ fixed problem with SetForeign()+FullName() returning symbol instead of
full name of foreign security.
+ added new AFL function IsContinuous() to check if "continuous" flag is
turned on in Symbol->Information window
+ OLE properties can be retrieved (DISPATCH_PROPERTYGET) directly from AFL
now using parameterless function syntax. This allows reading values exposed by
OLE automation directly from AFL code. Example:
AB = <FONT
color=#0000ff>CreateObject(<FONT
color=#ff00ff>"Broker.Application"); Stocks =
AB.Stocks(); // get collection<FONT
color=#000000> Stock = Stocks.Item( <FONT
color=#0000ff>Name() ); <FONT
color=#008000>// currently selected
"FullName : " +
Stock.FullName(); "Alias : "<FONT
color=#000000> + Stock.Alias(); "Address :
" + Stock.Address(); <FONT
color=#ff00ff>"Shares: " + Stock.Issue();
"Book value: " +
Stock.BookValue(); "Market : "<FONT
color=#000000> + Stock.MarketID(); "WebID :
" + Stock.WebID();
You can check if OLE object is valid by calling IsNull() function,
example:
AB = <FONT
color=#0000ff>CreateObject(<FONT
color=#ff00ff>"Broker.Application"); Stocks =
AB.Stocks(); // get collection<FONT
color=#000000> Stock = Stocks.Item( <FONT
color=#ff00ff>"INTC" ); <FONT
color=#800000>if( <FONT
color=#0000ff>IsNull( Stock ) ) {
printf<FONT
color=#000000>("COM object invalid (Null) - symbol
does not exist\n"); } <FONT
color=#800000>else {
printf<FONT
color=#000000>("COM object valid - you can access
its methods\n");
}
+ IsEmpty/IsNull and IsTrue functions operate with scalars and OLE
dispatches without upsizing them to array
CHANGES FOR VERSION 4.53.1 (as compared to 4.53.0)
addressed problem with broker.layers file. Now version 4.53.1 correctly
reads broker.layers file saved with older versions however note that old
versions are not compatible with new format.
layer properties dialog provides more comfortable setting of layer
visibility
other minor fixes
CHANGES FOR VERSION 4.53.0 (as compared to 4.52.0)
per-group intraday settings (filtering/daily compression) Use
Symbol->Categories: "GROUP" -> Use own intraday settings, clickon
"Intraday settings" button to define intraday settings specific to given
group.
intraday settings now allow to specify separate day (RTH) and night (ETH)
sessions
time filtering now allows to display:a) 24 hours trading (no
filtering)b) day session onlyc) night session onlyd) day and night
sessions only
new intraday time compression mode: Day/Night - shows two bars (day and
night) per day
daily compression can be now based ona) exchange time (available since
4.00)b) local time (available since 4.50)c) day/night session times
definable by the user (new)
when "activatestopsimmediately" is turned ON then cash from stopped out
positions is NOT available to enter trades the same day
easy access to selected category settings from Symbol->Information
window.
Workspace tree supports in-place editing of market, group, sector,
industry and watch list names. Single click on category name and just enter
the name
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("ActivateStopsImmediately") 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
format = 5 - returns DATETIME number with current date/time // new
formats available from version 4.51format = 6 - returns current DAY
(1..31) format = 7 - returns current MONTH (1..12)format = 8 - returns
current YEAR (four digit) format = 9 - returns current DAY OF WEEK (1..7,
where 1=Sunday, 2=Monday, and so on)format = 10 - returns current DAY OF
YEAR (1..366)
Custom indicators:If plot name is empty the value of such plot does not
appear in the titleand does not appear in the data tool tip
Plot( C, "Price", colorWhite, styleCandle );Plot( MA( C, 10 ), "",
colorRed ); // NOTE that this plot name/value will NOT appear in the
titlePlot( MA( C, 20 ), "MA20", colorGreen );
SetOption( "field", value )accepts new fields:"CommissionMode" -
0 - use portfolio manager commission table1 - percent of trade2 -
$ per trade3 - $ per share/contract
"CommissionAmount" - amount of commission in modes 1..3
"MarginRequirement" - account margin requirement (as in settings), 100 = no
margin
"ReverseSignalForcesExit" - reverse entry signal forces exit of existing
trade (default = True )
new AFL function: GetOption( "field" ) - retrieves the settings, accepted
fields the same as in SetOption.
Example:
PositionSize = -100 / GetOption("MaxOpenPositions");
new AFL function: GetRTData( "field" )- retrieves the LAST (the most
recent) value of the following fieldsreported by streaming real time data
source )(Note 1: this function is available ONLY in PROFESSIONAL
edition,calling it using Standard edition will give you NULL values for
all fields)(Note 2: works only if data source uses real time data source
(plugin) )(Note 3: availablity of data depends on underlying data
source- check the real-time quote window to see if given field is
available )(Note 4: function result represents the current value at the
time of the call/formula execution/, and they will be refreshed depending
on chart or commentary refresh interval/settable in preferences/. Built-in
real time quote window is refreshedway more often (at least 10 times per
second) )
