Revenge trading starts before the next trade.
The next order is only the visible part. The sequence usually begins when a loss creates an urgent need to feel back in control.
A loss changes more than the account balance. It can change the purpose of the next decision. Instead of evaluating a setup, the trader starts evaluating whether the next action can erase discomfort.
The hidden switch
The plan asks: is this setup valid? Revenge asks: can this make the last loss feel less final? Those questions can produce the same click for completely different reasons.
Interrupt the sequence
A useful counter-rule must be observable. After a stop, close the execution window for a fixed review interval. Write the reason for the next trade in one sentence. If that sentence refers to recovery, frustration or urgency, the decision is not ready.
