I've tried running with what I thought was a pretty simple strategy (1% gain on Aggressive, anywhere from 5-10 markets based on volume of trading). CAT has worked for hours or even days at a time, and then something will happen to cause a dramatic drop in the alt coin price and I'm left holding a bunch of devalued coins. At that point you have three choices:
1) Take the loss and move on
2) Wait it out but you can't trade any more on that pair in the meantime
3) Invest more and trade at the lower price while hoping it goes back up
So anything we can do to narrow down profitable settings is a good thing
