This is possible if your offline chart receives live tick updates and your offline chart generator names the offline chart properly. Regarding the latter, the name can't include a strange prefix like "RenkoEURUSD,M2" or "RenkoEURUSDm,M2." Having said that, EURUSD,M2 will work if you create your EA to run on the current time frame (0). Also, I once deleted all of my M5 history and set my offline chart generator to name as M5 just to see what would happen. The M5 button grayed out but was still able to be toggled. The offline chart was fully functional. I never actually tested it with an EA created to run on the M5 time frame, but I bet it would work. The pic is a current timeframe EA running on my offline Range Bars chart.
