Myst, you say:
X_DEV is designed to capitalize on a stocks weakness and strength by selling at average extreme highs and buying at average extreme lows within it's trend. Therefore, it can not have a "losing trade". We might be able to have an argument over this if a restriction to a certain time frame was a critical component to your case, but I don't think it is.
I don't think this is correct, and that X_DEV can have losing trades, and moreover should be able to have them. When a stock drops out of a range and starts trading in a lower range, that may be the only way to raise cash for new buys. I have heard this mentioned as a feature over AIM, that insists on selling at a sell price over the last buy price.
Now when this feauture hits you repeatedly, you get hurt badly. This is not to blame X_DEV: you might have picked the wrong stock, or didn't get the bands right. And every once in a while you are bound to get the bands wrong.
