I have been simulated trading in Ninja Trader for a while. I had a good strategy that makes $ based on order flow. I went to trade it real time (actual $) and it blew up. Is simulated so much different from actual that simulated can't be acted upon? I mean what's the point of back-testing or simulated trading when it gives a false sense of trading? Is the order flow from actual/live trades that different from simulation? How can I debug why my live trading blew up compared to simulation based on order flow? Thanks.
