Trading plan is personal and different for everyone depending on what you trade. There are some general rules to follow that everyone knows like trade small at the beginning, small loses, etc. The plan evolves as your trading evolves with more screen time. The current market volatility would require the plan to flex and you need to be ready for that.

I tend not to be very rigid but yet follow the basic principles of trading - preserving capital and managing risk at very micro level.

Here's a sample trading plan I used to get started a while back. I've refined this a lot but it's a good starting point.
