If you lose money trading the SIM, well, good luck. I made soo much on the SIM, I think I broke the software. LOL. With no emotions behind your trades, what good is SIM besides learning the platform? Maybe use SIM to test a system, experiment with placing stops, etc.... However, my point is that the profits you make in SIM might actually HURT you when you trade Live. I'm sure there are plenty of "Gurus" out there that use SIM and you wonder why they are soo composed.
