SeriesInfoInteger error in backtests MT4 build 604 after successful compilation

 

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?


Thanks

You can access it from Meta Editor while you have a .mq4 file open press F1. The Online documentation was due to be updated this week.
