Okay I'm following you now.  So you never act on a signal until after a full 24 hour bar has posted, and then you just take the current price as the exit price? 

I'd call that 'swing trading'; I'm using similar averages as well, with MACD sometimes for confirmation, to add size, or anticipate signals.

When I see these averages cross over it can happen during the day or during the night, and by the time I catch the signal the price can be 10+ points off from where it was when the averages crossed.  Typically I'm more concerned about exiting  long trades. For example if the crossover happens when price falls to 96 I'd rather take that exit than 8 hours later when it's already down to 86 by the time I notice the event.   

It'd be nice to get a text alert or something as soon as the signal is detected, instead of waiting until I check the charts.... I think this would have saved me few points by timing better.
