The key principle of High Probability Trading Strategies is to identify conditions with a high probability outcome and acceptable capital exposure. You can never know the outcome. You can never control the outcome.
You do control what information you will use to make a trading decision, and you do control the activity of trading, to buy, sell or do nothing. To improve as a trader, only focus on what you can control. Learn to only focus on information that is relevant to your trading plan to make a trading decision. Focus on implementing your trading plan.
If you focus on the trade outcome, your attention will be on something that doesn’t exist and you cannot control. You will waste energy, attention and your results will suffer, regardless of how good your trading plan is.
Master what you can control.
