    Actually, there is nothing stupid about this example. Over time, the only thing that matters is the statistical expectation. I have several strategies that buy under-priced convexity and the win rates per trades are as low as 10%. If your trade is positively convex you can get away with a pretty low win rate (though it feels very unpleasant at times and you want to pull the plug).

    So it's not MC but re-sampling. Your inputs are not random, you just re-shuffling actual data to provide stress scenarios.

    PS. pretty incredible how a fairly intelligent discussion has turned into a penis fencing contest

    I don't agree. It is stupid as you can name any winning rate from 1% to 100%. And theoretically any of these percentages can be profitable or just the opposite. It just depends of how big the profits and losses are. So winning rate on itself says nothing.

    This table shows that from 5% to 50% you always make money.

    So winning rate on it's own says nothing.
    And that's what you proof too with your 10% winning rate. So you did not understand my previous post.

    Ok, what was the actual statement you where trying to make? I understood it as "high winning rate is the only way to go". My point (regardless of what you said) was that what really matters is the overall statistical expectation (which is not completely true either, since other risk metrics matter as much, especially in a stand-alone strategy).

    My point is that winning rate on its own is irrelevant. You need additional info like average win or average loss.
    In short: the title of this thread makes no sense.

    Low winning rate is very possible too.So "high winning rate is the only way to go" is wrong.
