I too noticed that Matt's system uses simple MA instead of
exponential MA. Simple moving averages are more lagging, which is
probably what's needed for something as fickle as XLF. If there is
any other rational behind choosing simple moving averages, I would
like to know that.
Using a fast MA with a whippy stock is not necessarily the best
idea. You can just get whipped more. Sometimes an SMA is better
because it smooths out the price action.
This is why exotic MAs like the Hull, Kalman, Jurik etc don't
necessarily make better systems on their own. A plain Kalman
crossing system will get whipped six ways to sunday. You have to
combine them with something that reduces whipsaws like a hysteresis
channel or a trend filter.
When I was using plain MA crossings I often found the SMA gave
better results.
