I had the EA running on my live account
it works really well for a while. But at some point there will be a crash.
The goal should be to make enough profit by then and pull out the stake. there is NO EA that will profitably run forever. so i think 600% in 7 month is really good. after 3 months you have reached 100%. after a further 6 weeks 100% again. 3 more weeks 100% again ... Expotential growth
