You set a stop when you were calm and objective. Then price approaches it, and a voice says “just move it a little, give it room, it'll come back.” Obeying that voice — overriding your stop — is the single most expensive habit in trading, and nearly every blown account has it at the center.
Why the urge is so strong
Taking a loss means admitting you were wrong and feeling the pain now; moving the stop defers both. The brain strongly prefers the possibility of avoiding pain (“it might come back”) over the certainty of a small loss — even though that trade is exactly the math that turns small manageable losses into account-ending ones. The urge is loss aversion, and it's wired deep.
Why it's almost always wrong
Your stop marked the level where your idea is invalid. Price reaching it means the trade is wrong, by your own prior definition. Moving it doesn't make the trade right — it just increases the loss on a trade you've already been told is broken, and on a leveraged 0DTE option that loss can balloon fast. “It came back” the one time you remember; the times it didn't are what drain accounts.
Moving a stop swaps a certain small loss for a chance at a bigger one. Do it enough times and the bigger one arrives — that's not bad luck, it's the math.
Making override impossible
Willpower fails in the moment, so remove the moment: place a hard, protective stop when you enter and don't touch it. Once it's resting at the exchange, overriding takes a deliberate action, not just inaction — friction on exactly the wrong impulse. This is why automated exits matter and why NoVo places the stop by default the instant you fill. The expected cost of moving stops is measurably negative; the discipline is simply to leave it where your calm self put it.
