Can I assume you see the 5 and 10 cross then wait for them to cross both the 40 and 60 and then open a trade? And then exiting when the 5 and 10 cross again and then reentering the same direction if the higher ema's have not yet crossed for a change in the larger trend? What time frame have you chosen to trade of off? And what kind of stops are you using on that time frame? I have always enjoyed the use of ema's as part of my trading toolbox.
