demo trade for at least a year.
This will give you time to learn, practice and improve your skills. You will also get a chance to see different market environments. Every day is different, and the wild volatility that we've seen the past few weeks probably won't last forever. There will be periods where the markets barely move at all. Would your system and strategy work then? Would you be able to recognize a shift in trading environments and make adjustments? That ability and experience probably won't develop in only 30 days of demoing. Actually, I'll guarantee that.
There's a lot to learn, so don't be in a rush. Take the time to learn it right and make small improvements every day. Unless we go to a one world currency, there will always be opportunities to be there...k?

Why is it that you can only see things in hindsight??
I hope this helps!
