Disciplined trader is successful trader. Maintaining control and discipline in trading is the key to successful trading. Successful traders have a trading strategy and trading plan which they follow regardless of developments. How long did it take you to become a disciplined trader or are you still in the process?
Though easier said than done, nothing beats a disciplined trader. I know some retail trader who have employed a guy to make sure that they stick to their trading plan and don’t break any rules.
Bitter pill, but the patient needs it.
