Tape
Tape turns a plain-English trading idea into a backtested, deployed Polymarket bot in ~60 seconds.
Core trick
Compiles plain-English strategy into Python, backtests it on replayed CLOB fills, and deploys only after a rubric grader returns PASS.
Description
Tape turns a plain-English trading idea into a backtested, deployed Polymarket
bot in ~60 seconds. Active prediction-market traders have a discipline problem:
they know their strategy but can't code a bot, can't watch markets 24/7, and
panic-second-guess at the worst moment. With Tape you type a strategy in plain
English ("Buy NO on geopolitical markets above $0.92 that resolve within 14
days, skip anything under $50k liquidity"). Opus 4.8 compiles it into a runnable
Python strategy module, a backtester replays 90 days of real Polymarket CLOB
fills, a model-verifiable rubric (rubric.yaml) grades it PASS/FAIL with reasoning,
and on PASS it deploys to a budget-capped paper-trading sandbox whose first cycle
streams back live. The result: a trader locks discipline into code without
writing any code, and a hard budget cap means no strategy can risk more than its
allocation.
README excerpt
# Tape **Plain English → backtested → deployed Polymarket trading bot in 60 seconds.** Type a strategy. Watch Claude Opus 4.8 compile it to Python. See it backtested against 90 days of real market data. Deploy it as a live bot with a hard $25 budget cap. Built for [Claude Build Day](https://claude.com/build-day) hackathon. --- ## What problem does Tape solve? Active prediction-market traders have a **discipline problem**: they know what their strategy should be, but can't execute it consistently — because they can't code a bot, can't watch the markets 24/7, and panic-second-guess at the worst moments. Tape lets them lock a strategy into runnable code by typing it in plain English. Once compiled, the bot trades the strategy without them. Tape grew out of a personal Polymarket trading bot I've run on my own wallet for 80+ days — but it shares **no code** with that bot. Everything in this repo was written during Claude Build Day (see [CONTRIBUTIONS.md](CONTRIBUTIONS.md)). The prior bot is just the motivation: I wanted anyone to be able to deploy a disciplined strategy by typing a sentence, instead of writing the engine yourself. --- ## Demo ```text You type: "Buy NO on geopolitical conflict markets at >$0.92 that resolve within 14 days. Skip markets below $50k liquidity." Tape does (~60s): 1. Opus 4.8 compiles your sentence into a Python strategy module 2. Backtester replays 90 days of Polymarket fills → JSON metrics 3. Rubric grader applies rubric.yaml →
