It doesn’t even matter so much what the plan is. Just have one. Learn it, and stick to it.
NO PLAN, NO RULES, NO SUCCESS.

“Can you tell who will be a successful trader and who will not?”
“Yes, on a less technical level, I can say that after years of studying traders, the best predictor of success is simply whether the person is improving with time and experience. Many traders unconsciously acknowledge their lack of progress by continually jumping from one system or methodology to another, never gaining true proficiency in any.
As a result, these people end up with one year of experience, six times, instead of six years of experience. In contrast, the superior traders gravitate to a single approach — the specific approach is actually not important — and become extremely adept at it.”
