MD-doc Excellent post and excellent advice. To add to it I'll point out that the old mariners didn't have the advantage of paper-sailing. If they got in over their heads it was curtains. They had real courage. We can paper-trade, which is a real advantage, a valuable one that I'd recommend to anyone. Develop a system that contains entry criteria, exit criteria, risk and position size management. If it's profitable, then start trading it with real money, and NEVER violate your system rules.
