Dear Monirbd, which EA are you requesting ? This current last EA, I'am nor sure if it will good back test result as it is not based on signal generating EA. Its a kind of EA which you trade manually by help of any default indicator in MT4, I just put some calculation and strategy of flexible martingale in it so when you are trading with it, better watch it after sometime as any martingale is not good for 24 hours, once you notice you have picked enough trades so wait for them to be close or increase time frame specially in this EA as it will pick new trade only on new candle and as per the time frame you adjusted also it will calculate PIP distance, when all these 3 settings matched, then it will pick a trade unlike other martingales. I hope you get my point.
