Today I neither made nor lost money, or you could say I both made and lost money - a 0R day.
I have noticed that I do my best when I start off strong. If I lose with my first trade I am more prone to overtrading, trying to dig myself out of a hole that can get deeper and deeper. A solution may be to try to be especially careful with the first trade. Also, perhaps I need to work on accepting a loss. I thought I was okay with a loss, but the first one to start off the day may have a more lasting effect than I thought.
When you break your own rules, it is a difficult process to understand why you continue to do something you do not want to do and how to stop. You have to look deep inside. Not just in trading, but in life.
