The +$25 stop brought in +$31.34 today while letting it ride lost -$33. That brings the 7 days since looking at this "system" to +$170 stopping at $25 (but just using $25 for the first 5 days when, in fact, some days would of made a bit over that) and +$43 with just letting it ride over the last 7 days.

I realize 7 days is nothing in the scheme of things. I also know this will more than likely fall over (maybe whether I just let it ride or stop at the $25/5 units level) but I've got to try something and I'd rather have 7/7 positive days than 4/7.
