I fount out that ArrayCopySeries and ArrayCopyRates are 2 useful functions in MQL4. It does not really copy anything except when you call it first time. That saves some manual labour when I work in multiple timeframes.
And since it does not actually copy the whole array every time I call, It make program run faster.
Problem is these 2 functions does not exist in MQL5, only in MQL4.
Any one have same idea?
Do you use ArrayCopySeries and ArrayCopyRates in MQL4 and found disappointed when they are not available in MQL5?
