Any reason why you believe the guy on the other side of your real trade is dumb like a piece of paper ?
As far as the mechanical piece I think it is exactly the same. The point I was trying to make is when real money is involved, the more psychology, emotions, and the "real risk" you are willing to accept change.
It is easy to accept risk on paper, and when those numbers change in a real account vs. a paper account, that is when you really start to learn how to trade, which is why for me I have strict entry and exit points on every trade I make. I don't second guess myself.
When I went from paper trading to real trading, I started to see some losses got nervous exited positions I shouldn't have, that turned out to be winners, so I took a winning trade and turned into a losing trade, and wouldn't have done that on the paper account.
I know better know, but that is just something I went through and had to learn on my own, that I overlooked when paper trading. I am just trying to help the guy out, from what I learned.
