if you trade FX with a Bank you will need to invest at least 10 000 £$. so i decided to make my EAs work on cent accounts. if someone has only 100 Euros to trade with and convert that into a cent account. Thats also 10 000 cent and you will have a bigger back up in your margin. That way you run the Robot and makes money. Little profit here is better then no profit at your Bank savings.
