Personally, I would never let a Robot trade for me unless I am constantly monitoring it. There are too many horror stories about Robots trading an account's equity away. If you do use a Robot, test it for at least 30 days against a trusted demo account. Then test it live but only with micro or mini contracts. Don't trust "Backtesting" statements about any Robot. Forward test it yourself. I have tested dozens of Robots that claimed enormous profits and in forward testing most failed to make a profit and rapidly lost money. An example, I tested one Robot where the claim was that it would make $1,000 per day. In forward testing on a demo account, it actually lost $1,000 per day. I tried it on multiple currency pairs and it consistently lost money contrary to the promoter's claims.
I always recommend that a person become their own financial expert because there are too many scammers and scams out there trying to divest you of your hard earned dollars. The best preventive to being a victim is to become an expert, do your due diligence, read, study, put the necessary time in to become knowledgeable. If you are not willing to put in the time and effort then you will certainly be more suseptabale to being victimized.
