That's my point. Using stops has nothing to do with martingale.Using or improperly using leverage may lead to blowing up an account but again has nothing to do with martingale. Martingale is doubling your bet when you lose until you finally win. It works fine if you have unlimited capital.
I would say it differently: martingale does not allow the use of stops at all. There is a simple build-up of positions against the trend in the hope that the trend will soon reverse and your orders will finally go into plus. But with a constantly increasing load on the deposit, the chance to wait for a reversal and save your deposit decreases exponentially.
