Lake,
If that’s the math, then that’s the math, and I’m too lazy to challenge it.
I will say this though. I think SMAs and EMAs are all but useless except for very limited purposes and are inferior to weighted MAs (which Schwab’s charts will plot.) But all of them are beat by ‘triangular’ in terms of the crispness of the crossovers they create while not getting yanked around frantically by what amounts to just noise in the signal.
I’ll freely admit that’s more of an aesthetic judgment on my part than the product of backtesting. But in the course of a day, I’m easily looking at a couple hundred charts, and I don’t want to waste my time with ugly ones.
Maybe it’s my boat-building background stepping into the foreground. I want charts that look good and speak clearly, not the jumble of lines others tolerate.
