Quote from Maverick74:
There are no "truths" in trading. What people do with statistical analysis in regards to trading is to try to figure out how much of their result is just plain luck. Or put another way, how much of that "profit factor" is due strictly to variance.
In trading you cannot simply take 53 trades and call them independent. They are anything but. Almost all his trades are correlated which means he probably has maybe 3 or 4 data points. It's the reason why when they take polls to see who everyone is going to vote for President they don't just take 50 people who all live in hippyville and ask them. Or 50 people who only watch Fox news. They make sure their sample is legitimately random. You need to have men, women, republicans, democrats, independents, gays, war hawks, tree huggers and people who can't spell their own last name. You need to have a sample that actually resembles the voting public. Same with trading. The closest thing you can get to that in trading is a LOT of time. You need to trades across every type of market, different trade durations, different products and different correlations. And that ain't going to happen in a week or a month or even a year. Personally I think you need decades of data to "truly" get an idea. And that obviously is not feasible. So while there is no "correct" answer, I am pretty certain 53 trades is the wrong answer.
