if your system is good, then I am willing to implement it. Questions about the quality of your system:
* Was it just ONE lucky trade of 3500 pips, or were there 100 trades with 35 pips each ?
* Do you have only 1 open position at the time, or how many ?
* What is the biggest draw-down inside one round-turn ?
* What is the maximum number of consecutive losses ?
* What is the the recovery period ?

Also, "visual backtesting" is dangerous because you see the result already and tend to think: "yes, here, of course, I would have bought" (You might have cheated yourself). - Summary: please post the list of trades you believe you would have done. Even better would be if you open a demo account and make a forward test during at least 1 week. It is worth it, else the programmer spends one week on a system which proofs to not work.
