Description SHIN Nara 2014-04-14 05:54:06 EDT

Series.AddCandle(0, 0, 2, -1 ,1) should make a candle body but should not.

TeeChart .NET does it correctly.

Source code users can fix it implementing TCandleSeries.CalcItem method like this:

procedure TCandleSeries.CalcItem(ValueIndex:Integer; out AItem:TCandleItem);
begin
  with AItem do
  begin
    tmpX:=CalcXPos(ValueIndex);

    { Vertical positions of Open, High, Low & Close values for this point }
    YOpen :=CalcYPosValue(OpenValues.Value[ValueIndex]);
    YHigh :=CalcYPosValue(HighValues.Value[ValueIndex]);
    YLow  :=CalcYPosValue(LowValues.Value[ValueIndex]);
    YClose:=CalcYPosValue(CloseValues.Value[ValueIndex]);

    Left:=CandleWidth div 2; { calc half Candle Width }
    Right:=CandleWidth-Left;
  end;
end;
