Testing Strategy

Then you can test your trading strategy, modify it and hone it. The likelihood that your initial trading strategy is going to work is very slim.

Good, successful, money making currency trading strategies are developed over time. It's a complicated process. There are a million variables that go into which currency pair you will pick.
Then there are a million more variables in when you are going to buy, sell, and what you expect that currency pair to do.
Everyone needs a trading strategy when they begin and know the basics. But many traders jump from the learning straight to the doing, with real money.
It's like if a pilot who finished all of his classroom ours were immediately put in a real cockpit to fly a plane without any practical practice.
Pilots have to log a designated number of hours practicing flying in a flight simulator. Not only that, they have to exhibit a certain competency level before they are allowed to fly a real plane. You would never take a pilot out of the classroom straight into flying a real plane.
But that's what so many new traders do. They do a few trades on a and then jump the gun to trade right away.
The same impatience that leads them prematurely to trade the wild jungle of the forex currency market is the same impatience that will kill them and their bank account. Practice makes money, and there is no other way to start.
