Good Luck
Stupidity, gut , emotion and demo accounts....to me these are all intertwined.

You may have gathered by now that what I offer is not a signal service that says "buy this here and sell this there". What I am is a service that offers you the opportunity to take advantage of data and experience crunching to free you up to make a calculated decision on every trade you make. Remember, on any given day, with a lackluster attitude even the smallest trade can wipe you out. Been there, done that, got the T-shirt, and don't want the same to happen to you.

Now back to my first line. There is a role for demo accounts, but I must stress that the one thing that a demo account does not provide for you is the true gut kick that you get when you take a huge loss, or the euphoria you feel with a windfall trade.
Yet these are the two emotions that kill you in the real world.

In my humble opinion you have to be clinical and machine like when trading. As soon as you can come to grips that you must lose sometimes, you will be freed up to take the emotionless, surgical approach to trading.

So where does the demo account come into play if it can't mimic the real world emotion. For me it is quite simple. Apart from being a strategy tester, it is an "emotionless" trainer. Although I try very hard to think of demo money as real money, it is very difficult to do. So if I feel I don't need emotion in the real world, then through practice in demos, I try and limit emotions so I can trade without them live.

Now gut and stupidity play a valid role in demo accounts also. Try not to make this a habit though. On the stupid side, I will often do what I feel is a stupid trade, just to get it out of my system. This could be not taking profit when I should, not stopping out when I should, trading more than I should etc. I need to see that on a turn of a dime the Forex can turn against you. And this reinforces itself and prepares me in my real trading.

Gut is a real problem for traders. How many times have you said, "oh, I knew it", or "I knew I should not have!'? However when you act on your gut 9 times out of 10 you are wrong. Remember you are always right when your gut tells you something and you don't act on it, and always wrong when your gut tells you something and you do act on it!

So what to do? Be disciplined, clinical, don't listen to your gut, do stupid things (only in demos), feel no emotion, and above all stick to your plan. This is what I use demos for.
