While this FC's model has a great track record on futures for the ES and the YM. If i were to trade real money on it, I would strongly push and recommend trading options on it. Buying calls on this system allows you to have the unlimited profit of the futures contract, along with your risk being limited to only the premium. In a losing situation, the option is more likely to hold it's value because of the time left in the option, compared to the futures contract that could have much more heavy drawdown.
Even though the $ return is less on the options, it is my belief that because the risk is lower, you will be able to use more aggressive compounding to compensate for the lower returns as well as should have a smoother equity curve.
I'm still a novice to all the greek and complexity of options though, so take what i say with a grain of salt.
