Could a system that works for EOD trading also be used in daytrading? For example if I have a 20 day MA and a 5 day MA and a cross gives a buy signal. Could this also be applied in daytrading, like a 20 hour MA and a 5 hour MA, or a 20 minute MA and a 5 minute MA? And also a 20 week MA and a 5 week MA? I have never ever tried daytrading, but I have done some initial tests with weekly data and my system also seem to give good signals for weekly data, but slightly worse results. This idicates that the shorter the timeframe, the better the results (That is a generalization). Could this also mean, that my system would give even better results for daytrading? Have any one of you noticed something like this? Of course commissions and slippage plays a much larger role there... Thanks!
