Hi guys, I am sure many of you have had an automated strategy that looked really good on Market Replay or Live Simulation with Ninjatrader or other platform, but then you test it in the live dynamic crazy market and it fails to achieve the same results. If this has happened to you at some stage, can you please share why the strategy ended up not working when you went live with real money? Was it worse fills? Did you interfere with your strategy and let your emotions get the best of you? Would be good to hear and learn from others experiences. Thanks.
