Before using an EA on a real account, should it be reliable in 1 month backtesting, a year backtesting or all history chart backtesting ?
It's up to you.
As to me so I am using EA by trading (not backtesting) on demo for few weeks or for 3 months before using it live (on real account).
I am backtesting just to see how EA is working (lot size, MM etc). And I am optimizing with cloud to find good settings for the pairs. After that - I am attaching EA to the charts (demo account) to let it run with trading (just to see how it is traded).
After that - I am making the decision about to use this EA for trading live, or not.
newdigital, with MT4 what can you use to optimize or backtesting without cloud? I mean, is there some quicker/eficient tool to do it in Mt4 like mt5? I'm using the tools that mt4 have, but I don't know if there is some way to do it like mt5.....let me know please!
MT4? No, I do not know .... May be you know that I do not like backtesting in general :)
I am backtesting for MT4 just for 2 purposes:
if I understand the system and can trade it manually so I am not backtesting for MT4. Besides, I will never use any EA without any understanding about the system based, how it works and when I can lose the money with it (and how much).
As I know - some traders/coders are converting their EAs from MT4 to MT5 just to optimize the settings with cloud to find good settings for the pairs.
