Last few months blow up most Forex accounts

I agree with the theory behind this thread however even for the most experienced traders,the experience is actually a continual process and getting left behind leaves the best of traders in problem.Having been an active trader for the past 4 years i believe the uneasiness in forex is best dealt with by understanding your money management principles,unless a trader has a settled MM principle that deals with draw downs extensively while making profit,it's only a matter of time before a margin call occurs.Personally i've resolved maintaining for long term transactions flexible trade-able loss that accommodates continuous losses and still keeping the account intact otherwise the trade-able size is bogus.If you can loose 200pips 20times without a sngle profit and the account is still in good shape then you're using good trading lot that accommodates bad storms.The past 2 months have been here and there..but who know?The market goes up down or stays sideways for sometime just 3 possible directions then why the sporadic loss in FX ?
