Decide your falling-market rule while markets are calm
The worst moment to decide what you think about a falling market is while you are watching one.
That is not a comment on anyone's discipline. It is a description of how people work. The conditions that make a decision urgent are the same conditions that make it hard to think clearly, and those two things arrive together every single time.
Calm and stress are not the same reader
Read about market falls on an ordinary afternoon and they seem manageable. They are historical, they are described in past tense, and the recovery is usually mentioned in the same paragraph as the fall.
Live through one and almost none of that context is available. The numbers are moving now, the coverage is loud, the outcome is genuinely unknown, and the money involved is yours. Nobody reasons the same way in both settings, and expecting otherwise is the actual mistake.
What a written rule is
A rule written in advance is a record of what you concluded when you could think properly. That is all it is. It is not a prediction, it does not make anybody braver, and it carries no claim about what markets will do next.
What it does is narrower and more useful. It turns a question you would otherwise face under pressure into one you have already answered, so the moment becomes about following a decision rather than making one.
What people usually settle in advance
Rules vary enormously, because circumstances do. Broadly, they tend to cover the same few questions.
What would have to happen for this rule to apply at all, described specifically enough that you can tell on the day. What you would actually do, and just as importantly what you would not. How much time would pass before you looked again. Whether anybody else needs to be told, which matters when money is shared and two people can panic on different schedules.
What belongs in yours depends on your timeline, your obligations, how much of the money you might need soon, and how you personally react when things move. None of that is general knowledge. It is not something a website can hand you, and this one is not trying to.
Writing it down is doing most of the work
The act of writing forces the vagueness out. Intentions can stay comfortably unfinished while they live in your head, and a sentence you have to complete cannot.
It also creates a record you can check afterwards. If the rule turns out to be badly judged, you can see exactly what you thought and why, and improve it. An unwritten intention offers nothing to review, because it quietly rewrites itself to match whatever you ended up doing.
The point is the timing, not the content
None of this says what your rule should be. There is no version of that sentence that would be education rather than advice, and it would be a poor rule anyway, since it would have been written by somebody who knows nothing about your situation.
The only claim here is about when. A decision made calmly and a decision made under pressure are different decisions, even when the person making them is the same. Choosing which one governs your money is something you can still do today, and only today, because the option disappears the moment you need it.
