But the problem is they still trade with fear and emotions because 1) they don't have a trading system/plan and 2) they don't backtest the trading system/plan to confirm that it's consistently profitable. Until you have a proven trading system/plan to be profitable, you are ALWAYS going to trade with fear and emotions. Even when you have a proven trading system/plan, you will still trade with some fear and emotions because the trading system is only backtested and never forward tested enough and since the market is dynamic that it constantly changes, you never how well your trading system will fare in the future.
