I spent a bunch of time this weekend making a minor tweak to the model to incorporate what I'll call a "thrust" component. In a nutshell, when there is a significant drop in the VIX in a "healthy" market, the model will go with the flow as opposed to selling into it. This generates fewer sell/short signals (again, only in a "healthy" market) which is generally what one would expect.
That said, even after the tweak, a short signal was generated on Friday afternoon. This gives me more confidence and I may add to my short position early Monday if we see some strength in the morning.
Good luck all... and go Browns!
