Yes sir deaddog, You got that part right.Sound like the other reason traders fail. Not having a trading plan or not following the plan.
If you do not know how and why and when to Enter and Exit a trade day-to-day, everyday of the year, trading will be very complex for you.
Before I take a trade, I know my risk and I know where I my stop loss will be. And I know how to exit for a profit.
Yes, it is alot of work knowing all that before entry in the heat of the moment. But its better than the Shoulda Coulda Woulda after making a mistake starring at loss too.
