In r46244 the TOpenHighLowCloseSeries has a new property "Mode": selection "mOHLC" does the standard painting as before while "mChandleStick" paints the candlesticks that you requested. Since your code was mostly a copy of existing code I decided to stick to the old series type, but just add the painting modes. There are also properties "CandleStickUpBrush", "CandleStickDownBrush" and "CandleStickLinePen" to control painting of the up and down bars and the border and shadow line. I also added a little demo "financial" to the "demo" folder of the TAChart installation which demonstrates both modes. It would be nice if you could have a look if everything is fine - I'm not an expert in financial charts.

I also fixed the bug which ignored the true minimum of the data - therefore, it is no longer necessary to calculate the minimum by yourself, just have a look at the code in the demo project. And, finally, I modified the AddXOHLC method such that it automatically initializes the size of the YCount of the chart source if the current size would not be enough.
