... So, what are your suggestions on the plan
Ignored
Your plan is based on making one trade per month, winning that trade and then calculating, in advance, your yearly return. I have no idea what your trade criteria would be, but one trade a month just won't cut it. You don't even know how to trade, (btw, Van Tharp always said that doctors and lawyers made the worst traders he had ever seen, no offense) and you think you can place 12 trades and come out winning? Come on, this is dreaming, nothing more.
As Jen mentioned, doubling up is not going to work for if you lose 4 trades in a row - the time frame has nothing to do with this - which is not hard to do, then you've damaged your account to the point that you won't recover from it, mainly due to the emotional blow of doing so.
