A strategy that goes long or short QM doesn't have an asymetrical return profile. I.e., it isn't "picking up pennies". An example of that is selling options.
I think you misunderstand, what you're doing is even worse than picking up pennies, your strategy just boils down to punting futures with no hedge or any form risk management to your open position. You're just gambling on coinflips. If you backtest your "model" you'll find that external macro event induced crude oil moves will completely wipe you out because you have no hedge against them.
Your are correct about no hedge agains outlying macro events. But I'm not suggesting using this without any other variables in your trading decision. It may help make a trading decision.
