Although it has been talked about but briefly in the thread, the old IF1/IF2 really is a good way to force you not to hold past a very well-defined point when you have one of those "Great Moments in Live Trading" experiences.
It's one thing to go for a ride on a sim, but when the market goes against you for real, where for real = an IF1/IF2 scenario with your money on the table, then it means you made a mistake. What you thought was an FTT (SOC) wasn't and now you're in an FBO and you know where that's going to take you.
I got to experience this last Friday and to further abuse myself after taking 10 ticks, I've been eating tofurkey and drinking goat's milk all weekend.
I will not do this again. I will not do ..., etc.
