tar,
The nature of barjon's opening premise indicates to me (although I accept I may have misinterpreted his intentions) that he wants us to think in terms of generalizations - broad brushstroke stuff - all other things being equal etc. - and not get bogged down in nitty-gritty detail. Hence the sparse nature of his OP. That being the case, it's reasonable to state (as I did in my previous post) that drawdowns tend to be larger with lower success ratios and smaller with higher success ratios. For traders executing thoroughly researched and tested trading plans, there's nothing very controversial about that. Of course, there will always be exceptions. You have made a point on other threads of highlighting Myfxbook traders who have a 90%+ win rate and then blow up quite spectacularly. IMO, that's the drawback with Myfxbook and sites like it. Namely, prior to the account blow up, it gives the false impression to those who know no better that the trader concerned is God's gift to the markets.
If executed properly, a thoroughly researched and tested trading plan with a higher win rate (e.g 70% in barjon's example) will, by and large, broadly speaking, in most cases etc. etc., enjoy lower drawdowns than a methodology that has a win rate of 30%. Needless to say, this does not apply to the charlatans, ne'er-do-wells, scammers and braggarts that you are so adept at highlighting on sites like Myfxbook.
