As we continue to be whipsawed by the fickle markets here's a study model that has some attractive features including little time in the market, minimal drawdowns and a nice linearity. The model buys the 3 day low in SPY within the constraints of the M3 momentum/ relative strength algorithm. In order words the M3 modeling creates a momentum model and based on that ranking the 3 day low filter either stands back or signals a trade. You're only in it for a day or 2 so exposure time is limited and we have a .5% limit stop to further reduce risk. I'll post the 3 day low model signal henceforth in the daily pre-close update FYI since, like all the other models , based on buying or closing pre-close.
