I think that keeping the cash in a dropping trend is a good thing. In HUSKY it does appear that for the test cases Huskey ends up with more shares at the bottom(or at least close to it after a dip) than Vortex does. That is good if the trend goes up up up, but less so if the trend goes down again, but then it may recover the cash via a stop/loss or so.
If I have a load of cash on hand I do not worry. I worry when I have lost it!
