why getting a volume repeats itself
I tried with giving a variable and using extern variable. I tried to make it wait like 10 seconds after each request. Same thing.

You should issue RefreshRates() after the Sleep(), but anyway, this is not quite the best design how to use the EA.

Predefined Variables - MQL4 Reference do not update during a single OnTick unless you explicitly use RefreshRates - Timeseries and Indicators Access - MQL4 Reference

I encountered with this error in pretty complex scripts. In some scripts it worked okay, but in the some scripts even the simple one like this one, it just repeats itself. Same volume is shown constantly.
