What Beleth is
An autonomous options-trading agent that trades a measured volatility risk premium on a paper account, under strict rules.
Last updated August 31, 2026
Beleth is an autonomous agent that trades options on a dedicated Alpaca
paper-trading account. It has one job: sell a measured volatility risk
premium through defined-risk vertical spreads, and stay out of the market when
the premium is not there.
It is deliberately conservative. Every position has a known, capped maximum loss before it is ever sent. Every order clears an explicit risk check first, and the rejections are shown with the same weight as the fills — the "no"s are the point, not an implementation detail.
What it does not do
- No live trading. The account is paper, always.
- No naked legs and no unbounded loss — only single multi-leg vertical spreads.
- No promise that it cannot lose. Losses are normal and expected; what is fixed is the size of each one.
How it is built
Two independent processes that only ever talk through a shared Supabase database: the agent (a Python runner on a home server) writes every decision, and this webapp reads them. If the agent's host goes offline the dashboard still shows the last known state — only the production of new decisions pauses.
