When you notice you are about to override your own rule, what is the first thing you see?

A lot of traders describe the moment a rule starts to feel negotiable. It rarely arrives as a clear thought. It is more often a small story: this setup is different, the rule was written for a calmer market, just this once. Those stories tend to show up before the order is placed, which makes them easy to miss if you only review trades afterwards. One idea that comes up often in discussions of trading psychology is that the rule itself can be less important than the signal that warns you it is under pressure. Some people write down their own warning phrases in advance and read them when they feel rushed. Others notice a physical cue first, such as a faster pulse or a tighter jaw, and treat that as the trigger to pause. It is also worth saying that noticing the urge does not mean it was wrong. Sometimes the rule really does need revisiting, and the best place to do that is away from the screen, not in the middle of a session. What is the first sign, whether a thought, a feeling or a physical cue, that tells you a rule is starting to bend?
