TC, this is really excellent work. I have noticed on the version I've been collaborating with PT on that very small changes (.01) in some of the settings have a noticeable effect on the outcome. I suspect this is just an artifact of the data though, where just one or two trades are being executed or excluded that would not be with a slightly changed setting. In other words, going forward probably won't give you precisely the same results, and a sligthly modified setting might be better. And as I have mentioned before, in reality the trades will not be able to be executed to the precision that the program calculates them, since you will seldom if ever get the NDO price *exactly*. But, as a strategy for trading and timing, my feeling is that as a practical matter this is getting close to about as good as it gets for non-daytraders.
