Hey Mr. Paul. This is a really great question, since proper use of multiple time frames is the way to turn a winner into a windfall. Mult. time frame trade management is most appropriate for slightly longer term players (not intraday scalpers).
Personally - for my short term (1-5 day) trades, I look for daily signals, then use price action at the open and close of the day for
entries and exits. The day after entry I use 15 min. charts to identify locations to hedge a portion of my position. When the daily chart tells me to exit, then I close the position and the hedge.
