    AmiBroker 4.29.9 Beta Read Me
    March 7, 2003 20:47 
    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 4.29.9 beta" written in the 
    About box.
    CHANGES FOR VERSION 
    4.29.9 (as compared to 4.29.8)
    
      added key shortcuts for range mark begin (F12), end (Shift+F12), hide 
      (Ctrl+F12) (they are also available in Keyboard editor so assignments can 
      be changed) 
      chart scroll left/right are now accessible from keyboard editor 
      (ChartScrollLeft, ChartScrollRight) 
      if type-in is selected from the main menu then watch list selector 
      dialog is displayed. 
      fixed sometimes wrong sort when many explorations were run one after 
      another with some non-numeric columns. 
      Study() works correctly even when trendline is drawn past the last 
      available data bar.
    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.

    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 
      Alt+o shortcut

    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) 
      Currently defined shapes areUP ARROW = 1, (below
