I am trying to use the function
CheckLoadHistory(string symbol, ENUM_TIMEFRAMES period, datetime start_date)
to check history. Just found that function in mql5.com. I have used that program to develop my own library, which I include in my EAs. My EA including that library compiles and everything seems to work fine. but when I call CheckLoadHistory in my EA, an error emerges:
The question is, where is a real documentation of MQL4 in the present? Can we use MQL5 syntax, or not? Which functions can we use from MQL5 and which not?
