Revenge trading and the cost of immediacy

Q: What is the sharpest single test for a revenge trade?

Would I be taking this trade if the previous one had won? — The others are symptoms and can be absent. The counterfactual goes directly at the cause: whether the previous trade, rather than the market, is the reason this one exists.

Revenge trading is the specific case of tilt where the next trade exists because of the last one. The tell is simple: if the previous trade had won, would you be taking this one? If the honest answer is no, the market is not the reason you are here.

What makes it so costly is timing. The re-entry usually comes fast — often within minutes — and speed removes the only thing that would have stopped it, which is the gap where you check the setup against your rules. A trade taken in ninety seconds has not been checked. It has been felt.

The size usually rises too, and for a reason that sounds rational: to recover the loss in one trade rather than three. But raising size after a loss is exactly backwards relative to the risk. You are increasing exposure at the moment your judgement is measurably worse, which turns a normal losing streak into a serious drawdown.

The standard countermeasure is a cooldown — a fixed period after a loss during which you do not enter. Fifteen minutes is a common choice and there is nothing magic about the number; the mechanism is that it forces the gap back in. It works because it is mechanical. A cooldown you can waive when the setup "is really good" is not a cooldown.

One thing worth being clear about: a loss is not evidence that you did anything wrong. If you followed the method, the loss was part of it. Treating every loss as a mistake to be corrected is itself a cause of revenge trading, because it creates a debt that feels like it needs settling.

What to take away

The test: would you take this trade if the last one had won?
Speed is the mechanism — a fast re-entry has skipped the check against your rules.
Raising size after a loss increases exposure exactly when judgement is worst.
A loss by the rules is not a mistake, and treating it as one creates the debt that drives revenge.

In the app the same chapter ends in your figures rather than an example: how often you did the thing it describes, over your last ninety days. You pick one change to make, and Evidence checks afterwards whether it actually changed — from your journal, arithmetic, no opinion involved. Questions you get wrong come back a week later and again a month after that.

What is the sharpest single test for a revenge trade?

Would I be taking this trade if the previous one had won? — The others are symptoms and can be absent. The counterfactual goes directly at the cause: whether the previous trade, rather than the market, is the reason this one exists.

Why does raising size after a loss make things worse than the maths alone suggests?

It increases exposure at the moment judgement is measurably worse — The two effects compound: a bigger position and a worse decision at the same time. That combination is what turns an ordinary losing streak into a drawdown that is hard to recover.

A cooldown rule works mainly because…

it is mechanical and forces back the gap in which you would check your rules — The duration is arbitrary; the mechanism is not. Anything you can waive in the moment provides no protection, which is why it has to act without your agreement.
