It's actually a simple mean reversion system that buys uptrending stocks that have dipped and shorts downtrending stocks that have rallied. You'd notice this from a short look at the charts of the stocks traded.
Thanks!
The system is a simple mean reversion system. Buy low, sell high. Short rallies, cover on dips.
I find that stocks provide enough trading opportunities for the system I trade so I haven't found the need to trade options.
