I'm not an expert too, but i can say that 2000USD is not enough, especially with 0.1 lotsize. I used 0.4 multipiler which lead me to 0.01 starter lot size with a 2500USD account. Everything went fine for 2-3 days but last Friday my account has evaporated thanks to EUR/USD has just went to South unstoppable. The copier started with 0.01 lot and went until 2.56 what -it's not surprise- my account didn't survive.
So, the main concept is quite good, but martingale kills your account sooner or later if you don't have insufficient money on it. Martingale doesn't work in casino games(Blackjack, Roulette etc...) neither in long term.
