what is consistency rule in prop firm?

By checking how consistent your profits/losses are the prop firm aims to see if you have a strategy you are following or if you keep trying new things every day. When you follow a fixed strategy and risk management plan it shows in your profits/losses because they will always be within the same range.

But when you do not have a risk management plan in place today you will make 20% profit/loss and tomorrow you will make 1% profit/loss so there will be no consistency and this will lead you to have a low consistency score. usually, a consistency score of above 80% is considered good by prop firms.
