DislikedIf your system is a winner it will make you quicker money if it is a loser then it will blow your account quicker.I calculated that if you have a constant 1:1 RR then you need at least 51% win rate to be always winner with a martingaleIgnored
If a system has positive expectancy, then applying martingale is about the silliest thing anybody can do, since martingale does not alter long term expectancy, but merely increases the risk of ruin.
MM in itself can never provide an edge; all it does is alter the size/frequency distribution of wins and losses. Martingale provides an exchange of guaranteed recovery in the short term for guaranteed eventual ruin in the long term.
