I never look at $$$$$ as money, “its time” I loose it ? how much “Time” will it take take to recove? Put some real $$$$$$$ in a sub-acc. and let it “MARGIN CALL” make it amount that will cause some anxietiy. then test your reactions, and how you control your emotions. if you come out of it reasonabely unscathed, you have done well. After all, it's is only paying for you Education I only trade “Time” And I have been full on Margin Called 3 times. So far my Education has cost over $50K. But boy I'm a better trader.
