CHANGES FOR VERSION 5.54.0 (as compared to 5.53.1)

• New Analysis: "Sync chart on select" did not respect linked charts and symbol lock. Fixed.
• AFL: new function XYChartSetAxis( "chartname", "x-axis name", "y-axis name" )
• AFL: new function XYChartAddPoint( "chartname", "text", x, y, color )
• New Analysis: Implemented XY (scatter) charts in Explorations
  Example:
  
  // XY chart coding example
// This formula generates 2 X-Y scatter charts that display relationship between
// final trade profit and MFE and MAE

Buy = Cross( MACD(), Signal());
Sell = Cross( Signal(), MACD() );
Short = False;
Cover = False;

Eq = Equity( 1 ); // single-security equity  this evaluates stops (if you use them) and removes extra signals

Entry = Buy OR Short;
EqAtEntry = ValueWhen( Entry, Eq );
Profit = 100 * ( Eq - EqAtEntry ) / EqAtEntry; // percent profit

// MAE and MFE below use CLOSING equity, MAE and MFE in the report use high/low price
MAE = 100 * ( LowestSince( Entry, Eq ) - EqAtEntry ) / EqAtEntry; // percent MAE
MFE = 100 * ( HighestSince( Entry, Eq ) - EqAtEntry ) / EqAtEntry; // percent MAE

bi = BarIndex();

Len = bi - ValueWhen( Entry, bi );

EntryPrice = ValueWhen( Entry, BuyPrice );
// if you prefer MAE/MFE using high/low price
// uncomment the lines below (long only Version)
MAE = 100 * ( LowestSince( Entry, Low ) - EntryPrice ) / EntryPrice ; // percent MAE using low
MFE = 100 * ( HighestSince( Entry, High ) - EntryPrice ) / EntryPrice ; // percent MAE using high

Exit = Sell OR Cover;
dt = DateTime();
Clr = ColorHSB( Status("stocknum"), 255, 255 );
for( bar = 0; bar < BarCount; bar++ )
{
   if( Exit[ bar ] )
   {
      // item text consists of two parts
      // first part (before \t) is a item name displayed immediatelly on XY chart
      // second part (after \t) is a tooltip hint text that is displayed in the tooltip
      // when you hover on given item
      // here we will only use hint text
       HintText = "\t" + Name()+"@"+ DateTimeToStr( dt[ bar ] );

       XYChartAddPoint( "Profit vs MAE", HintText, MAE[ bar ], Profit[ bar ],Clr );
       XYChartAddPoint( "Profit vs MFE", HintText, MFE[ bar ], Profit[ bar ], Clr );
       XYChartAddPoint( "Profit vs trade length", HintText, Len[ bar ], Profit[ bar ], Clr );
    }
}

XYChartSetAxis( "Profit vs MAE", "[MAE]", "[Profit]" );
XYChartSetAxis( "Profit vs MFE", "[MFE]", "[Profit]" );
XYChartSetAxis( "Profit vs trade length", "[Length]", "[Profit]"  );


Filter = Exit;
AddColumn( Eq, "Equity" );
AddColumn( Profit, "Profit" );
AddColumn( MAE, "MAE" );
AddColumn( MFE, "MFE" );
AddColumn( Len, "trade length" );
  
• {{INTERVAL}} gave incorrect (unstable) results in custom n-tick/n-range/n-volume charts when used with multithreading. Fixed.
• Interval(2) returned incorrect (unstable) results in custom n-tick/n-range/n-volume charts when used with multithreading. Fixed.
• Preferences: Currency page was not working properly. Fixed.
• Status bar look matches now appearance settings (esp. visible in VS2012 style)
• Parameter window now allows to select combined styles (like styleHidden) as well as their components styleNoRescale+styleNoDraw independently
• User setting for minimum pixel spacing in X grid (Tools->Preferences, "Axes / Grids") - it is recommended to keep it at default value (60 pixels), for denser grid use less spacing (minimum 30 pixels), for wider grid use more x spacing (maximum 120 pixels)
• Sometimes panes did not refresh to final size when chart sheets are switched (for example - one tab has only one pane second tab has two panes). Fixed.
  

CHANGES FOR VERSION 5.53.1 (as compared to 5.53.0)

• Trend lines and other drawing tools sometimes were blinking or disappeared in 5.53.0. Fixed
• Plots with styleDashed mixed with plots using other styles could cause continuous growth of rendering time in 5.52/5.53. Fixed.
  

CHANGES FOR VERSION 5.53.0 (as compared to 5.52.0)

• Triangle drawing tool now supports filled interiors
• Vertical selector line was flicerking with RT update when more than one chart window was open. Fixed
• SetChartGradientFill renamed to SetGradientFill
• SetGradientFill now has 2 more arguments: baseline and baselinecolor. Allows reverse gradient chart (such as underwater equity) and 3 color gradients top->baseline->bottom
• Added 2-year and 5-year x grid spacing
• Gradient chart sometimes disappeared when null values were in the data set and chart was zoomed out to the maximum. Fixed.
• GUI: Preferences dialog adjustments (moved "bold" checkbox in color page, removed obsolete "show vertical line" boxes in charting page, moved candlestick outline color settings from charting to color page )
• styleClipMinMax interferred with styleGradient in 5.52.0. Fixed (both styles can now be used independently as well as combined together)
  

CHANGES FOR VERSION 5.52.0 (as compared to 5.51.2)

• Chart themes implemented, featuring new look, new grid settings, new background gradient fills, predefined themes for more details see: http://www.amibroker.com/guide/h_themes.html
• Charts: X-axis algorithm rewritten (now it is clearer and prevents overcrowded/unreadable X labels)
• Charts: added native gradient area charts. Gradient chart is obtained using styleGradient. Upper gradient color is specified by color parameter in Plot() function, bottom gradient color is either background color or can be defined using SetChartGradientFill function. styleGradient can be combined with styleLine
  
  Example
  SetChartGradientFill( colorLightOrange, colorPaleGreen );
Plot( C, "Close", ColorBlend( colorPaleGreen, colorBlack ), styleGradient | styleLine, Null, Null, 0, -1 );
  
• Charts: Plot/PlotForeign/PlotOHLC now adds extra parameter "width" that controls the width of the line. Positive values specify PIXEL width, negative values specify width in percent of current bar width. So for example -20 will give you dynamic width that is 20% of bar width. Example:
  Plot( C, "Close", colorBlack, styleBar, Null, Null, 0, 1, -20 /* line width as percent of bar */ );

• Eliminated build-up of rendering times caused by growing of MFC temporary GDI object maps in non-UI threads. Now rendering engine uses direct WINAPI calls without MFC
• View->Filtering menu was disabled in 5.51.x. Fixed
• Data window was not working in 5.51.x. Fixed
• " Show middle lines" = "NO" causes date axis to be moved down outside visible area. Fixed.
• Selector line was not working correctly in 5.51. Fixed.
• Bold dotted trendline did not work in 5.51 BETA. Fixed
• AFL: LinearReg/LinRegSlope/LinRegIntercept/TSF/StdError display proper error message when user passes negative (wrong) parameter
• Study tooltip information now includes also number of bars between start and end of the trendline
• New Analysis: saving last column layout works better
• Account manager: Edit->Undo menu was missing. Fixed.
• GetFnData() now supports retrieving "Address" field too
• On Win98 and above drawing engine uses DC_PEN/DC_BRUSH for speed
• Optimize() reduced possibility of IEEE floating point accumulation errors with steps < 1 (such as 0.01)
• PlotShapes() does not plot multiple times in same x/y pos anymore - it results in faster rendering when shapes overlap (large zoom outs)
  

CHANGES FOR VERSION 5.51.2 (as compared to 5.51.1)

• PlotShapes() rendering was slower in 5.51 than in 5.50. Fixed.
• Interpretation was blank with new rendering engine. Fixed.
• Charts: Quick AFL was disabled in new rendering engine causing slowdowns with > 100K bars. Fixed
  

CHANGES FOR VERSION 5.51.1 (as compared to 5.51.0)

• fix for low-level Gfx* functions causing crash when multithreaded GDI was enabled

CHANGES FOR VERSION 5.51.0 (as compared to 5.50.5)

• Charts: Multithreaded GDI implemented for super-smooth UI response and preventing GDI-intensive charts from detoriating entire UI responsiveness
• Maximum rendering time limit increased to 1000ms (1sec) when multithreaded charts + GDI are enabled (allowing 2 times more complex plots without Warning 901)
• 64-bit only: eSignal plugin - first BETA version of 64-bit eSignal plugin (3.0.0)
