Here is a monthly chart of GBP/USD since 1982 (24 years). It is pretty obvious that no matter how bad drawdown periods could have been a Net end result is still very green. I've done a very basic calculation and the succession of drawdowns doesn't look too bad, yes there are very large losses of up to 1500+ pips involved, but gains offset any consecutive historical drawdowns/realised losses. But I know you will say that all that can change and when does one establish that fact? The answer is I don't know, but than again nobody does until PF starts declining to 1 or less, I guess that would be the time to realise that it does not work any more. When you run any other business you keep using same old formula year in year out, until the time profits start slipping away. But if one was to trust historical performance based on this monthly chart, then there is positive expectancy present, for sure. Ball in your court![]()
I think as B1S2 pointed out and Illiquid, that basically it works, but by no way represents a solid way to make trade decisions. I agree.
