If you want to be pro, be like a robot do not trade with emotions , easier said than done i know , but success lies in conquering your emotions totally, become a Forex terminator. Trade goes against you , proceed to next trade.
If you going to get a developer to code you an EA Robot , its not smart to give them your strategy idea especially if it works and makes money, best thing is to learn how to code your EA yourself keep it private. I have personally started making my own EA by learning processes it least that way the developer can not steal your strategy. Its worth the learning process.
