Question: Why do EA produce different results from live accounts? Could EA be trusted?

 

Hello Everyone, Been testing many EA's and some give same results as live accounts and some are totally different. Here are the questions for those long time traders and coders.

Could EA here in MQL5 be trusted?If not, how do we avoid this? And why do MQL5 allow this?

Do MQL5 screen sellers and their products before release?

Please let me know as I am learning what MQL5 market place is all about.

Thanks in advance :)
