    tks, got it. Found an example that adds in a delay check so the CPU does not spin out of control

    if (lastRefresh.AddMilliseconds(refreash_delay) < DateTime.Now){
    ChartControl.Refresh();
    lastRefresh = DateTime.Now;
    }

    Thus far I am able to set the value to at 500 (ms) and all seems ok, but it's not a busy time for the market right now either...well see in the AM

    thanks for the reply

    It's late, but isn't there a ChartControl.Refresh()?


    There's probably a good reason nothing happens in OnMarketData with respect to your drawtext. I'm sure you are about to find out.
