Improved Model

The "Gold Model" was stopped out twice in a row on Thursday and Friday when the market was more than 1% down and it was long. So I now took another of my old models that uses a different approach entirely but only gives rare signals. Those signals over-ride the "Gold Model" signals. The combination enhances return. It would have been short Thursday and long Friday. It signals short for Monday. In simulation, it's average win is 1.3% a day and average loss 0.36% with a 62% probability of winning.  The Sharpe ratio is 0.52. This is only based on data since January 1st. Trading 1 NQ contract the biggest drawdown since January 1st is USD 3852.

I ended up USD 200 down on the month in trading at the end of Friday after being USD 700 up on Wednesday. Plan is to switch to trading NQ contracts with a stop loss next week. I am a bit wary of taking the signal from the new model for my first larger trades and so maybe will wait till Tuesday.

I made decision trees in Powerpoint for using the model in each of the 4 possible states where yesterday's trade was: long, short, long but stopped out, and short but stopped out. There is then no discretion over putting on trades. Here is one of the four decision trees, to give you an idea:
