I get the impression you don't do charts, and I can't fathom how anyone can trade successfully without them. Take some time to learn the patterns, how to draw trendlines, and how to read the indicators. Next, limit yourself to set-ups that are clearly one sided in your favor, even if you have to wait days for that to happen, as your account leaves you very little margin for error. Maybe paper trade a bit to get a handle on things and steel your nerves.
Most people who trade successfully use charts. Zeev talks fundamentals, but he buys and sells his intra-day and swing positions based upon the charts.
I would take this opportunity to learn as much as you can about charts and technical analysis in order to improve your odds trading charts and futures.
Furthermore, if you want to trade futures, I'd avoid days where there's a lot of news (like econ stuff and earnings) initially to steer clear of getting stopped out on some stupid spike.
I'm always happy to share what I've learned, and many here are the same.
