Hello. In MT4 and MT5 in Tools\Options\tab Charts is information how many candles, regardless of used time frame and trading symbol, are on entire chart: as much as scroll bar can go to the left side. However I believe that MT4 and/or MT4 may very rarely (but it can happen!) have problems with loading entire chart history for years ago (larger time frames) IF user doesn’t manually open the chart. So this problem related to incomplete chart loading may happen at the background of MT functionality without user opening the actual chart. If there was a need in custom tool that it scans entire history, such incomplete historical loading problem could have serious negative consequence. I am wondering if there is any technical solution (or tool) which could either prevent described problem from happening (resulting that both MT4 and MT5 for 100% sure loads entire history of charts without user opening them) and/or solution that could at least report when such problem happened? Thank you in advance.
