Quote from volente_00:
And that battle is only won once you have your psychology straight
No.
First you backtest your trading system in bear, bull and flat markets.
If the system is profitable and the drawdown is reasonable THEN you can trade with absolute confidence and discipline, what you call having "your psychology straight".
Trading with discipline and confidence is much, much more easier to do if the trader knows his system will make him money in the long run.
Psychology will get you nowhere if you are not sure about your system. Even the most disciplined trader cannot make money if his system has no statistical edge to begin with.
