CHANGE LOG
CHANGES FOR VERSION 4.55.1 (as compared to 4.55.0)
  implemented workaround to Windows XP status bar display problem causing 
  plugin status indicator not 'disappearing' sometimes
  fixed problem with crash sometimes occuring when calling Import() OLE 
  automation methodwhen AB was not running.Versions 4.54-4.55 are 
  localization-enabled and month names are localized too, localized strings have 
  to be setup at the start of the program, but this was working correctly only 
  if GUI was launched. When creating AB OLE object without GUI month name string 
  were notset-up correctly and this caused problems. (This fixes problems 
  with CSI/UA export as well as AQ trying to import to non-existing instance of 
  AB)
  fputs/fgets/fclose/feof file functions are now protected against using 
  null file handle(common coding error among AFL users)
  Parameter names are not truncated in the parameter list 
CHANGES FOR VERSION 4.55.0 (as compared to 4.54.0)
  Median and Percentile calculations include current bar 
  new symbols added via CategoryAddSymbol trigger workspace ticker list 
  refresh
  calling COM methods returning nothing (void) does not cause "type 
  mismatch" message
  duplicate parameters are no longer produced when user specifies parameter 
  names with trailing/leading spaces in Param()/ParamStr()/ParamColor() 
  now it is safe to call AB.RefreshAll() from inside of AmiBroker because 
  this method is protected against locking up / looping by not allowing 
  consequent refresh if previous refresh occured in less than one second 
  Parameters window now is resizable 
  Parameters window now support date and time parameters.Corresponding 
  new AFL functions are:ParamDate( "Name", "Default date", format = 0 ); 
  where:"Name" is a string holding parameter name"Default date" 
  is a string holding date in any any 
  format:YYYY-MM-DDMM/DD/YYDD-MM-YYetc, etc.format - 
  defines return value format, allowable values are:0 - return value is a 
  NUMBER and holds DateNum. Ie: 990503 for May 3, 1999,1 - return value is a 
  STRING formatted holding date according to your windows regional 
  settingsParamTime( "Name", "Default time", format = 0 
  );where:"Name" is a string holding parameter name"Default time" is 
  a string holding date in any of the following 
  formats:HH:MM:SSHH:MMformat - defines return value format, 
  allowable values are:0 - return value is a NUMBER and holds TimeNum. Ie: 
  133515 for 13:35:15 1 - return value is a STRING formatted holding time 
  according to your windows regional 
  settingsExamples:Title = WriteVal( 
  ParamDate("ParamDateAsDateNum","2004-05-14"), 7.0 );Title = 
  ParamDate("ParamDateAsString","2004-05-17",1); 
  portfolio/individual backtester/optimizer, new setting in 
  AA->Settings->Portfolio:"Limit trade size as % of entry bar volume" 
  (default = 10%)This prevents from entering the trades greater than 
  given percentage of entry bar's volume.For example if backtesting daily 
  data and today's volume for thinly traded stock is 177,000 shares, setting 
  this to 10% will limit the maximum trade size to 17,700 shares (10% of total 
  daily volume). This prevents from 'affecting the market'by huge orders. 
  IMPORTANT NOTE:Some instruments like MUTUAL FUNDS come without 
  VOLUME data. To backtest such instruments please set this field to ZERO (0). 
  This effectively turns OFF this feature. Otherwise you won't be able to enter 
  any trade at all. Suggestions are welcome how to handle this problem 
  automatically (maybe just detect if bar's volume is ZERO and then allow 
  entering any size?)
  K-ratio calculation changed following the change made by its creator, Mr. 
  Lars Kestner.Quoting from the book "Quantitative Trading Strategies" 
  from 2003 by Lars Kestner:[ - - - ]" The K-ratio is a unitless 
  measure of performance that can be compared across markets and time periods. [ 
  - - - ] Traders should search for strategies yielding K-ratios greater 
  than +0.50. Together, the Sharpe ratio and K-ratio are the most 
  importantmeasures when evaluating trading strategy performance. Note: When 
  I created the K-ratio in 1996, I thought I had created a robust measure to 
  evaluate performance. In mid-2000, trader Bob Fuchs brought a small error to 
  my attention regarding the scaling of the K-ratio. He was correct in his 
  critique and I have corrected the error in this text. Publications prior to 
  2002 will show a different formula for the K-ratio. The updated formula in 
  this book is correct." 
  Mr Lars Kestner has corrected his formula based on this 
  critique:K-ratio = slope / ( sterr * per ) 
  slope: Linear regression slope of equity line sterr: Standard error of 
  slopeper: Number of periods in the performance test
  Special thanks to Jeremy Berkovits who brought that to my 
  attention.
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) ) 
  Supported fields:"Ask" - current best ask price "AskSize " -
