Stop-losses vs. mental stops: why the rule needs teeth
A risk rule only works if it executes without your permission in the moment. Mental stops fail exactly when they're needed.

"I'll get out if it drops to X." Almost everyone has a number in their head. Almost no one honors it under pressure.
The problem with mental stops
A mental stop relies on you making the right decision at the worst possible moment — when the position is already against you, loss aversion is screaming, and "give it a little more room" sounds perfectly reasonable. That's not a risk control. It's an intention, and intentions evaporate under stress.
The research on loss aversion predicts exactly this: realizing a loss feels bad enough that we'll take more risk to avoid it. The mental stop quietly becomes "I'll get out at X… or maybe X minus a bit… or when it comes back."
What makes a stop real
A real stop has teeth — it executes whether or not you feel like letting it. That can mean a resting order with the broker, or a rule in an automated system that closes the position on your pre-set terms without asking.
The difference isn't discipline; it's architecture. You move the decision out of the panicked moment and into a calm one, then make it self-executing.
The principle generalizes
This is the same logic behind a maximum daily loss, position-size rules, and defined-risk structures: decide the limit when you're rational, and arrange for it to enforce itself when you're not. A rule that depends on your willpower at the moment of maximum temptation isn't a rule. It's a wish with a number attached.
