These are martingale EA. i personally used this EA. with 1000 USD real account.. yes it earned me quiet a lot for few days more then i expected. but suddenly with market move 1 side it started to show 30-60% Draw down. i was scared. then i backtested it and i saw many times in last few years this ea have wiped out account even with lowest settings..
Like all martingale EA this has no special or anything.
