The Biology Behind FOMO in Trading

Hey {{first_name}},

Did you know that your brain is a prediction machine?

That's literally what it does. It's constantly trying to forecast what's going to happen next so it can keep you safe.

200,000 years ago, if you heard rustling in the bushes, your brain had to predict: Is that a snake or just the wind?

If you predicted wrong, you died.

So your ancestors who survived were the ones who couldn't tolerate the uncertainty of not knowing. The ones who erred on the side of caution and treated uncertainty as danger…

And you inherited that nervous system.

That's why trading feels so hard and FOMO feels impossible to ignore.

In daily life, your brain can usually tolerate uncertainty because the stakes are low.

You don't know if your friend will text back or if the restaurant will have what you want. Your brain handles that fine because neither of these are a big deal, right?

But trading is high-stakes uncertainty.

You don't know if price will keep moving.

You don't know if your setup will work.

You don't know if you'll make or lose money.

When stakes are high and uncertainty is high, your brain activates a threat response.

And when your nervous system is in threat mode, it wants to DO something to resolve the uncertainty.

That's when FOMO happens.

Here's how the FOMO pattern tends to play out:

You see a setup developing and you're not sure if it'll work.

That uncertainty creates discomfort. You start feeling tightness in your chest, a knot in your stomach, restless energy…

And you can’t get rid of the urge to make those feelings go away. Your brain starts saying: "I can make this stop. Just take the trade. Then you'll know."

So you take it.

And unfortunately, you aren’t focused on if it meets your criteria or not because taking the trade resolves the uncertainty and gives you an answer. More importantly, it stops the discomfort.

This is action as anxiety relief.

The problem with that? It works. Temporarily.

So what happens when you click that button is the anxiety disappears for a second and you get a hit of dopamine. This causes the discomfort to go away and your brain got what it wanted.

But then the trade starts moving and you have new uncertainties. How far will it go? Will it reverse? Should I move my stop?

And the cycle continues…

You can't eliminate uncertainty in trading.

Every trade has uncertainty. That's what creates the opportunity. If you knew what would happen, there'd be no trade, no edge, no profit.

Uncertainty is the cost of the opportunity.

So the question isn't "How do I eliminate uncertainty?"

It's "How do I tolerate uncertainty while I execute my process?"

By building tolerance the same way you build any capacity… Through practice.

Start small with micro-exposures to uncertainty in daily life.

You could start by not checking your phone for two hours. You'll feel uncertain about whether you got messages, it’ll feel uncomfortable not having that comfort of checking the screen constantly... Sit with those feelings and notice the discomfort. And then, notice you survive it.

Another thing you could try is ordering something new at a restaurant without asking what's in it or if it’s good. You'll feel uncertain about whether you'll like it or not, but sit with it and experience something new.

These small practices that don’t feel like a big deal actually train your nervous system that uncertainty isn't dangerous.

And when you can do this in low-stakes situations, you can build capacity for high-stakes ones.

So here’s the thing about the nervous system… it doesn’t work cognitively. Meaning that there is no logic involved because that part of the brain is offline. The nervous system works through your body.

So what do I mean that?

When you are activated, you need body-based practices that rewire your response to uncertainty at a physiological level. When that happens, then you can turn your logic back on.

So how do you do that?

Try this:

That's it. It's extremely uncomfortable and the first time is the worst time, but that's the point.

You're practicing tolerating discomfort without resolving it with action.

Do this daily for a week. Even if it’s just two minutes.

I can bet that just about anyone reading this has never actually sat through discomfort or an urge fully. You’ve always given into it to make it go away.

When that happens, your brain and body can never learn that urges and discomfort end. Right now it only knows that you have to give into the urge to make the discomfort go away.

And when you can repeatedly practice sitting in the discomfort without doing anything about it, your nervous system learns: "I can feel discomfort and survive it."

When your nervous system learns uncertainty isn't an emergency, FOMO loses its urgency.

When you can sit with uncertainty without immediately acting, you create a gap between the urge and the action.

That gap is where choice lives.

Not willpower or discipline. Choice.

Most traders try to build discipline by forcing themselves to stick to their plan. But when your nervous system is activated, your prefrontal cortex goes offline. That’s where willpower lives. But when that part of the brain is offline, you lose access to it. So no, you can't access willpower when your emotions have taken over.

Which means the work here isn't to have more discipline in your trading. It's to regulate your nervous system so discipline becomes possible. If you don’t regulate, you’ll never be able to “just be more disciplined.”

This practice helps do that though.

It teaches your body that uncertainty is tolerable. That discomfort doesn't require immediate action. That you can feel something without doing something.

You already know the practices… Micro-exposures in daily life and the two-minute body exercise.

Do those.

But here's the most important part: just notice when uncertainty triggers you. In trading and in life.

Don’t judge yourself for what comes up, just develop an awareness for it because you can’t change a pattern you don’t see.

Tuesday on the podcast, we're going much deeper.

Uncertainty intolerance is just one of three psychological structures that create FOMO.

The other two: control compensation (why you try to micromanage trades when you feel powerless) and worth-based trading (why losses feel like proof you're not good enough).

I'm breaking down all three, the somatic practices for each, the 7-Day FOMO Fast for when you're spiraling, and how to use FOMO as information instead of something to fight.

This is honestly probably one of the deepest episodes I’ve done yet.

Reply to this email if you have any questions about FOMO or the exercises, and we’ll see you on Tuesday!
