At the moment, practically every my month ends with losses, but I only practice on a demo and sometimes with a small lot on a real account, so is normal situation that first we loss.
I do not know if there is a possible consistent profit from forex, my beginnings are not the best and you can only see losses, sometimes I can make a small profit.
Interesting question, but with such a large amount of transactions on the Forex market, it is rather unlikely that a 50 lots transaction could change anything, maybe with a small broker.
I have reviewed a few copy trading websites, although I am not sure that it is profitable for my account, so I think it's better to learn the trade and discipline yourself. Demo account with virtual money for my is the best solutions and later with small lots try in real.
