Revenge Trading and Overconfidence

The revenge sequence

A loss, then a feeling that the market owes it back, then a trade taken without a setup at double size to get even faster, then a larger loss, then the same again. Accounts that took months to build are emptied in an afternoon this way. The sequence is predictable, which means it can be interrupted with a rule: after two consecutive losses, or a loss larger than planned, stop for the day. No exceptions, because the exception is the point at which the sequence begins.

Overconfidence

Five wins in a row at a 50 percent win rate happen one time in thirty-two, which is to say often. A trader who reads them as proof of skill increases size, relaxes filters, and trades more. The sixth trade, sized for a hero, loses more than the five won. The rule is the same as for revenge: risk per trade is fixed and does not rise with mood, and a run of wins is a reason to check the journal, not to change the plan.

Variance

Any strategy with a positive expectancy produces streaks of losses and streaks of wins as a matter of arithmetic. Neither streak tells you anything about the next trade. Accepting that in advance, and writing it into the plan, is what allows the same rules to be followed through both. Course 8's performance lessons put numbers on it.

Interrupts

• Daily loss limit: stop for the day at a set loss.
• Consecutive-loss rule: stop for the day after two or three.
• Cooling-off: no trade for one full bar after any rule break.
• Post-streak review: after five wins or five losses, reread the plan before the next trade.
• Fixed risk: the percentage per trade does not change with results.

Key takeaways

• Revenge trading is a predictable sequence and a rule interrupts it.
• Overconfidence after wins produces the same oversizing.
• Streaks are variance, not information about the next trade.
• Fixed risk, daily limits and cooling-off periods are the defences.
