Build high probability profitable forex robot

Would like a high probability profiting Forex robot, one that works same way as back test, a robot that is not public and is not shared with others. Would like to see two year back tests (2012 to 2015) and live results if possible. I am not interested in account management, so please do not bid if that is what you are going to suggest.. Would also like to know brief description of the strategy upon bidding.
