Here is one from me.
A big problem with moving average cross over is that the wip-saw almost eats away the profits of the last trend.
You get an edge by sizing up your position at approximately the wip-saw heights.
Now when a long trend comes in, it allows for a large number of size ups in position, as opposed to the wip-saws.
The 'where' and 'how' of sizing up has to be worked out and may well be different for each instrument.
Also worth noting is that this works better for tighter moving averages, again tighter is different for different instruments.
