sma seems unbelivable in backtesting. It never quite works out in real trading. Try papertrading this system before trading. With SMA crossover on a daily chart you will get clobbered.
Not to mention if you try to go long/short with a SAR type of system with this approach you will NEVER find any stock to short since better informed traders that use more advanced indicators on shorter time frames are lightyears ahead of you. They are taking their profits as you are just getting the signal.
