Hello,
Does any different of MT5 EA code structure compare with MT4 EA code structure? So, does all EA which running in MT4 can use into coming MT5?

The short answer: No.

The long answer: Stuff coded in MT4 needs to be tweaked to run in MT5

Unfortunately, there is no easy way. The problem is because the position/order/deal structure in MT5 is way different from the one of MT4. And while MT5 is currently still in beta, they haven't implemented some important functions yet (like OnTrade()).

The link below takes you to some MT4 scripts that help you convert your MQ4 code to MQ5 code. Nowhere near perfect but it is a start.

Much thanks. More useful information. :-)
I am in enhance my MQ4 ea. Usually, the first & end of year, EA must run very poor result.

MQ5 lanuage is ok, but if Metatrade can backward run MQ4 or MQ5 in optional installation. It is fine for many many EA programmer or EA user. Just only my opinion. ;-)

No problem at all!!!

I believe that metaquotes could have easily done a good version of this themselves, but because they are there for the broker as opposed to the trader, it wasn't in their financial interests.

Therefore the more programmers who know about these INCOMPLETE but hopefully helpful scripts the better the FF trading community will be.
