How it works

A book you can keep, and a place for your code.

Prediction-market crypto UP/DOWN windows are public books. Fathom Terminal is software for watching those books, keeping a tape, playing the tape back, and attaching your own plugin to an execution framework. It ships in paper mode. Live order placement is not included.

Feed and book

A feed is a sequence of prints: a time, a bid and ask on each token, and the sizes shown at those prices. The desk reads the top of the book. Incomplete quotes are skipped or carried forward; they are not invented.

Recorder and replay

A recorder writes the prints you saw. Replay walks the same prints later, at a speed you choose, including a delayed desk like the one on the homepage. Nothing is invented on replay, and replay is not a live order path.

The plugin slot

Buyers add a module under strategies/ that exposes a Plugin class. The engine ships with strategies/stub.py only. The stub follows the book, writes a status line, and places no orders. There is no included trading method.

License

After payment, you receive a per-buyer zip and a signed FT1 token. At startup the engine verifies the token offline with a bundled public key. There is no phone-home. The copy is watermarked so a leak can be traced to an order.

Payment

Request an order code, then send the exact tier amount to the published TON or Solana address with memo FT-XXXXXX. Official USDT-on-TON must match the dollar amount exactly. Native TON is accepted within 5% of the equivalent. Wrong amounts and missing memos go to the operator for review; they are not auto-issued. Details are on the license page.

This is not financial advice and not a recommendation to trade.
