The Rule Added After a Single Bad Session

A rule does one job: it applies a decision made calmly to a situation that is not calm. Every teardown orb trading rules lalinetlasiren has logged of a bloated plan finds the same origin, which is that a rule written the evening after a loss is fitted to that loss and to nothing else. Never trade this name on a Tuesday after a gap up sounds like discipline and is a description of one intraday session. A set of trading rules assembled that way slowly narrows until the opening range breakout it was built to trade is refused most mornings for reasons nobody can defend.

One Session Is One Observation

A single bad outcome carries almost no information about which of its features mattered. The gap, the day of the week, the volume, the news, the size, the timeframe and the entry all coincided, and the loss cannot tell you which one caused it. Writing a rule against any of them is picking a suspect from a lineup of seven with no evidence.

The Emotional Timing Is the Problem

Rules written within hours of a loss are aimed at the feeling rather than at the mechanism. They tend to be prohibitions, they tend to be specific, and they tend to be added rather than replacing anything. The same person a week later, looking at forty sessions, usually writes something quite different and much shorter.

Wait for the Third Instance

A workable convention is that nothing becomes a rule until the same pattern has appeared three times in the log, from three separate sessions, with the common feature written down before the third one occurred. Until then it is a note, not a rule. That single delay removes most of the accumulation without removing anything that was ever going to generalise.

Count What the New Rule Would Have Refused

Before adding a line, run it backwards over the last three months. A rule that would have prevented one loss and also blocked eleven winning trades is easy to reject once that number exists, and impossible to argue about while it does not. Most one incident rules fail this test badly, and the test takes about ten minutes on a decent log.

Notes Are the Right Container

The instinct after a bad session is a real one and it should not be suppressed, just directed somewhere useful. Write the observation in full, with the date, the instrument, what the 15 minute range looked like and what the mistake felt like at the time. Notes cost nothing, they accumulate into evidence, and they can become a rule later when there is something more than one morning behind them.
