Thanks for the useful information and the timely response. I've been overwhelmed by all the interfaces and objects in TeeChart and blew right past the simple solution to try vastly more complicated ones that didn't work.

I'm using a candle series. Given a valid date for one of the candles, how do I get a percentage of where it is on the horizontal axis to pass to the ColorBand tool? What I am really trying to do is put vertical bands on the candle chart to show when in market positions.
Thanks in advance.
