Using this idea you only bet when your batteries are charged, you have two hours guarenteed before your next crisis, you know the market is moving (almost every day something is moving), you feel good, you got enough sleep, you've already been to the bathroom, your favorite Starbucks/McDonald's/$WIFI-HOTSPOT is open, etc. Make sure you're ready to bet, watch the market, bet, go eat lunch.

I've been playing with this very idea. I've had to mentally hold one position over night. I don't like holding a position. I want to be in and out in two hours.

Gambling on the stock market is risky. I think lots of people, maybe most of the people that gamble this way, want to be rich. Well, I don't. As the OP asked the question, I only want to make enough to comfortably get by so I can spend the rest of my time living and learning.
