Fister, I kept spreadhseets on and off, I can give you relatively accurate info when my travels are over in october. If you want to play the game it sounds like, give binary options a shot. You have to be right something like 80% of the time to be profitable, but its definetly more of a straight gamble, extremely liquid, and allows you to act on intraday/week hunches.
I would never do it but that's just because I feel I can make better use of my money, once I have some again. I did a monte carlo analysis of binary options with current volatility ratings and depending on the day you havre to be right 15 to 30%more often then with straight shorting but its quick and easy and occasionally offers interesting opportunities for low dollar amt investments.
