Wow.. simply incredible to read that what you did so diligently in SIM you didn't carry over into trading live. Don't get me wrong though, I completely respect you sharing this, and my experience is exactly the same. I simply could not take the same trades when trading live that I took trading SIM. I would hesitate on entries, and ended up taking trades much later, which always stopped out given a tight stop since the entry wasn't in an ideal place.
If you look over your trades, would they have been taken the same way as if you were SIM trading them? I know its hard to play the "what if" game, but is this just a case of you starting to trade live during a string of losses that would have naturally happened even in your SIM trading, or would these trades have actually gone better if you managed them the same way as you did your SIM trades? It sounds like you didn't honor a trade that should have been closed sooner, which you would have closed in SIM, but didn't in the real account. So is your account down simply because of this one trade that you let go against you too far?
