hi there
There is no Set Color Option for "open = close"
open 200 close 300 = (body and line) color is red (OK)
open 200 close 100 = (body and line) color is blue (OK)
open 200 close 200 = (body and line) color is black <-- How to ???
thx |

Hi cha,
In ChartDirector, "close >= open" is an "up day", otherwise it is a down day.
if open 200 close 200, the candlestick body will be filled with the "red color". However, the candlestick body is zero in height, so you cannot see the fill color. Instead, you see the border color, which by default is black for all the candlesticks.
You can use CandleStickLayer.setColors to modify the color of the border. See:
http://www.advsofteng.com/doc/cdcpp.htm#CandleStickLayer.setColors.htm
An example in C++ is like:
myCandleStickLayer->setColors(0x00ff00, 0x00ff00, 0xff0000, 0xff0000);
Hope this can help.
Regards

hi Peter
Is it impossible to set the color to black if the open and the close price are the same?
thx |

Hi cha,
Yes, I think the default in ChartDirector is to set the color to black when the open and close price are the same. See:
The image below is from the "Candlestick Chart" sample code included in ChartDirector. Note the last candlestick in the above chart. It is black.
