Everything is possible in forex, so you are asking the wrong question. The correct quesiton would be:is it sustainable? and the answer is NO. It is not sustenaible in the long term to make 50-120% a week without going broke. So my gues is: 1) you are gambling or, 2) you have been on an incredible good streak. either way, expect a brutal drawdown any time soon. Sorry to dissapoint you , but I am here to give realistic answers. If I were you, I would review some basic money management rules. Good luck
