Differences between MQL4 and MQL5

 

Both of them are OOP. As far as I see, the main difference is that MQL4 does not have a standard library.

What else?

Is there any other big difference between those two?

mql4 actually has a standard library. It's not documented, as, I guess, it's not yet fixed.

There are many topics about the difference between mql4 and mql5 on this site, please do some research.

The main difference is in "position" concept, which don't exist in MT4/MQL4. Seems like MetaQuotes will eliminate all other differences in the nearest future
