Module 5 · Trade Management · Lesson 3

When a trade moves against you fast

Every options trader eventually has a position move against them faster than expected. A short-dated, near-the-money spread can gain value quickly on a sharp move in the underlying, a direct consequence of the gamma behaviour covered earlier in the curriculum. The move itself isn't unusual. What matters is having a clear-headed plan for it before it happens.

When it happens, there are really only three honest options in front of you: close the position and take the loss, roll it, or let it run.

A simple example. You're short an NDX put spread and the index drops sharply in the first hour of trading. Your spread, which was comfortably out of the money the day before, is now much closer to being tested. You have a decision to make, and you have it whether you're ready or not.

Option one: close it

Closing the position locks in a known, defined loss right now, rather than an unknown one later. It's often the simplest and calmest choice precisely because it ends the uncertainty. The loss is already known because it's a defined-risk spread: the maximum you could lose was fixed the moment you opened it, as covered in the lesson on position sizing.

Option two: roll it

Rolling the position, covered in the previous lesson on rolling a position, gives it more time and sometimes better strikes. It's a legitimate response to a fast move, but only when it's a deliberate choice rather than a way to avoid facing the loss. Rolling on impulse, in the middle of a fast move, is a very different thing from rolling as part of a plan you set out calmly beforehand.

Option three: let it run

If the position is still within its planned max loss and your original thesis for the trade still holds, doing nothing and letting the trade play out is also a legitimate choice. This is different from freezing. It's an active decision that the situation hasn't actually changed the case for the trade, made with the same clarity you'd want for the other two options.

The option that isn't really an option

The one response that tends to cause the most damage is freezing, or worse, adding more size to a losing position to try to "fix" it or bring down the average price. This is the same mistake covered in the earlier lesson on risk management: don't add to a losing trade. Adding size to a position that's already moving against you increases exposure to the same risk that's already hurting you, at the exact moment your judgement is least reliable.

Rule of thumb. Decide your reaction to a fast move in advance, while calm, because a fast market doesn't leave time to think clearly in the moment. If a plan already exists, you're executing it. If it doesn't, you're improvising with real money on the line.
