This is an exercise recommended to a guy who applied for prop trading at a firm in Sydney. Get some charting with bar replay function. Pull up some futs or FX so you know there will be continual movement. Must be an instrument you haven't been tracking, so it's new to you.
You have to stay 100% in the market - no wait and see - you're either long or short on every bar. You can hold long/short as long as you like before flipping your position.
Mark your positions on the chart as the bars unfold. L, S, L, S...etc. The aim is to see how quickly you can run your account down to 10% of the initial equity. In other words, go long when you expect the market to tank, and short when yoou expect it to pump. Don't use a "method", just use your gut feel.
Then you go back and look at your trades. It's supposed to uncover something valuable about your trading method. I won't say what because it might ruin it.
