I did some back-testing with George’s 9-36-15 strategy using SPY and SH, and it is definitely a technique you want use. Believe it or not, bears could have shorted this historic rally by trading SH (the inverse S&P 500 ETF) and lived to tell about it.
Since the rally began in September, if you had gone long SH on every 9-36-15 cross-up, and gotten out before the bell, you would have only lost 2%. That’s pretty miraculous, and way better than having your face completely ripped off. Of course, trading SPY would have made profits instead, showing that it’s always a good idea to trade in the direction of the primary trend no matter how good your techniques are.
I used a longer 1,000 day period for the results that you can see on the 9-36-15 Cross page.
The rules that I used were suitable for a computerized strategy. For example, after a cross, it just goes long. In reality, you could probably get better entry points by waiting for a dip on the 1-minute chart, or using additional signals from the stochastic, MACD, etc.
