I have try your EA and it seems the lot multiply is too risky. It is martingale system. You need to search broker that can offer maybe infinity leverage, if not, your account will blown away. Maybe you can add some function which user can choose what kind of multiply they want. e.g. 1.2x, 1.3x, 1.5x, 2.0x. Just my 2 cents.
If it is not martingale system, then at least show your history to other.
