So, get online. Run your forex trading platform.
Get yourself ready by reviewing your trading system and your trading strategy.
Have your trading plan prepared for all the eventualities.
And trust your system to work.
You have tested that system over and over again.
And you know that there is no perfect system that would never lose.
So what if you lose in your first trade?
The important thing is you trust your system enough that in the long-run, it would produce profitable results for you.
