Almost everyone makes huge profits during simulated trading, but when it comes to real trading, they often struggle and blame their poor performance on having a good mindset during simulation. The reason is that simulated trading feels faster because the money isn't real and time seems to pass quickly, so there's no market noise. When you're focused solely on your own domain, if you can filter out all the noise in real trading, you definitely won't do too badly. Give it a try, but filtering out noise is not an easy task.
