I currently use NT's default VOL indicator for volume, and GomCD to see the per-bar delta because I like the wicks on the candles. However, I'd like to consolidate my screen space and instead use only GomDeltaVolume and show the total volume as shown in the screen shot. However, the GomDeltaVolume indicator relies on the recorded Gom data for not only the delta, but also the total volume. This means that if I lose my internet connection for a few minutes or do not have recorded data, I cannot see the total volume for the bar. I changed this bit of code, but the result is the same. Any ideas?
protected override void GomOnMarketData(Gom.MarketDataType e)
{
int delta = CalcDelta(e);
