Built by a trader for traders who are tired of losing to themselves.

I started building Pendulum Trader after one too many sessions where I watched myself click a trade I swore I wouldn't take, and a funded account I'd worked months to pass evaporated in a forty-five minute window I couldn't explain. I had read the books. I had journaled. I had rules taped to the monitor. None of it mattered in the moment it needed to. The part of me making the decision at 10:18 on a Wednesday was not the part of me that read the books on a Sunday night.

The turning point was realizing that revenge trading, FOMO entries, and blown accounts are not discipline failures — they are nervous system events. By the time you're clicking, the autonomic decision has already been made, thirty to ninety seconds earlier, in a part of you that doesn't read trading books and doesn't speak in language at all. Every piece of trading-psychology advice I'd ever read was aimed at the wrong layer. It was trying to lecture a prefrontal cortex that, in the exact moment it mattered, was no longer in the room.

Pendulum Trader exists to close that gap. The trade journal tells you what happened. Pendulum tells you why — by tracking the layer underneath the trades: your nervous system state, your emotional incidents, your shadow trader personas, and the exact pattern of your tilt events. The AI coach reads your real data, not hypothetical scenarios, and runs guided sessions when you need them. It's the tool I needed and couldn't find, so I built it.

What Pendulum Trader is

Pendulum is a trading psychology operating system. It sits on top of your trade journal and tracks the layer underneath the trades — your nervous system state, emotional incidents, body check-ins, shadow trader personas, and the exact pattern of your tilt events. The AI coach reads your real data (not hypothetical scenarios) and runs guided sessions in five modes. The goal is not to replace the journal. The goal is to make the journal finally useful.

What Pendulum Trader is not

It is not financial advice. It is not a signal service. It is not a trading room. It is not an alpha generator. We do not tell you what to buy, when to buy, or how much to risk. Those decisions are yours alone — and we take the risk disclaimer seriously enough to put a link to it in every marketing email we send.

If you are looking for someone to hand you a setup, Pendulum is not for you. If you already have the setups and the edge and you are still blowing up your account to the same psychological pattern every month, Pendulum is built for you.

The stack underneath

Pendulum runs on Next.js and Postgres, uses Anthropic's Claude for the coach, Stripe for billing, and a small set of purpose-built features: polyvagal-based nervous system tracking, an 8-persona shadow trader model, CBT-based dangerous-word detection in journal entries, and 11 somatic regulation exercises drawn from trauma-informed therapy research. The Hermetic Principles library and the Polyvagal Theory for Traders long-read go deeper into the framework if you want the background reading.
