The purpose of demo accounts is to prepare you for this. Demo accounts are not only for traders to try out their forex trading strategies, but they are also dry-runs for the real trading execution. You should have gotten a feel of how the market moves and how it can affect your decision-making in your trading. Of course, a demo account does not involve real money. And sometimes, that may make all the difference in clouding your judgment. But you should trust your judgment and how you have developed and fine-tuned your trading strategy. Your trading system should be the solid foundation to back you up in every move. It would be better if you have it all written down so that you can easily go back to them whenever you feel having any doubts or confusion.
