I am looking for an automated strategy to maximize profit by trading the smaller intraday swing while using the longer term price action to specify the direction the short term trades should be taken in (including position sizing, etc.). Position sizing and PA analysis would take place in the higher TFs and would be set on a discretionary basis. Would would be the best automated intraday strategy for this? An MA cross-over?
Look at http://www.robotictradingsystems.com I am not associated with the company though, but I believe it does what you want.
