Walter,
I'm finding that using a multi day time frame.. even if its short like 1-5 days like i'm doing is a bit easier to profit than intraday. As I'm sure you know most of my automated trading strategies I have worked on in the past were all intraday strategies. This is really one of my first moves into a slightly longer time frame. I am not sure if its just the fact that this way slippage/commission is less of a factor... or if its related to I have a much larger pool of potential trades, so I can find the one matching what i'm looking for instead of being constrained to the specific stocks my intraday strategy is geared towards..Not sure which it is, just seems "easier"
