When you say sample size is 400, and then 100 samples each, do you mean trades? I'm not really following the math there as if that's the case then you're nowhere near 10 trades per month. Over a 10 year period you have 120 months.
Also you're using four USD pairs, so if you have overlapping trades then you are creating a multiplicative risk problem where the dollar exposure is concerned.
