Polymarket BTC 5m Hedge Ladder Bot is an open-source Polymarket trading bot for BTC Up/Down 5-minute prediction markets. It is a Python algorithmic trading bot that reads live CLOB orderbooks, runs a gradient-boost orderbook predictor to forecast ask moves 10–15 seconds ahead, and executes a hedge ladder strategy — buying UP and DOWN tokens for a combined cost below $1.00 to lock direction-independent profit at settlement.
If you searched for a Polymarket bot, Polymarket CLOB bot, BTC 5m trading bot, prediction market trading bot, orderbook trading bot, Polymarket arbitrage bot, or live Polymarket trading strategy — this repo is the full implementation: strategy code, predictor weights, paper dashboard, dry-run mode, and live execution via py-clob-client.
Built for live trading. This bot runs against real Polymarket CLOB books — sub-millisecond
inference, 200ms poll cadence, and a hedge ladder that locks edge before the 5-minute
window closes. Paper metrics translate to live execution: the same predictor, the same
pair-cost ceiling, the same fill logic. When you flip DRY_RUN=false, you run the same
engine validated on live microstructure, not a demo fork.
It is not a hype dump of screenshots. It is the actual strategy skeleton:
- how the orderbook is read under time pressure
- how a gradient-boost predictor forecasts ask moves 10–15 seconds ahead
- how a hedge ladder turns a rising token + a dipping token into a pair that costs less than $1
- why that pair prints stable profit at resolution — win or lose on BTC direction
If you came here to understand how someone actually thinks about short-horizon Polymarket microstructure, you are in the right place.
See SEO Keywords at the bottom of this README for the full list of search terms this repo targets.
In a BTC 5m binary market there are two tokens: UP and DOWN.
| Outcome | UP pays | DOWN pays |
|---|---|---|
| BTC finishes higher | $1.00 | $0.00 |
| BTC finishes lower | $0.00 | $1.00 |
Hold one of each and settlement always returns $1.00.
┌─────────────────────────────────────┐
buy UP @ 0.46 │ │
buy DOWN @ 0.48 │ pair cost = 0.94 │
│ redemption = 1.00 │
│ locked edge = 6.0% │
└─────────────────────────────────────┘
Direction does not matter. The only thing that matters is assembling the pair
for a combined cost strictly below $1.00 before the window ends.
That sounds trivial until you watch a live book: the cheap pair appears for seconds, then vanishes. The bot exists to detect, predict, and ladder that moment.
| Metric | Value | Notes |
|---|---|---|
| Directional accuracy | 76.8% | 12s forward ask direction |
| Qualified signal accuracy | 78.4% | only when confidence ≥ 72% |
| Hedge completion rate | 91.2% | Leg 2 filled before window end |
| Average locked edge | 5.6% | mean 1 − pair_cost on hedges |
These are the same numbers the paper dashboard surfaces from apps/paper-dashboard/src/lib/metrics.ts.

-
Detect pressure — stream both orderbooks. Compute microstructure features (imbalance, microprice, mid/spread/imbalance velocity, depth ratio, tick intensity).
-
Predict 10–15s ahead — a compact gradient-boost ensemble forecasts the next ask move. Validated directional accuracy is 76.8% overall and 78.4% on qualified signals (confidence ≥ 72%). Inference is designed for speed: sub-millisecond on CPU, no neural net, no GPU.
-
Buy the rising token first — when the model says a side is about to rip, take Leg 1 immediately at the ask. Waiting here is how edge dies.
-
Ladder the dipping token — the opposite token is usually selling off. Place / wait for Leg 2 at a target price such that:
price_leg1 + price_leg2 ≤ max_pair_cost (default 0.97) -
Lock the hedge — once both legs fill, you hold a full pair. Profit at resolution ≈
1.00 − pair_cost(net of fees).
The art is not “predicting Bitcoin.”
The art is predicting the book long enough to buy both sides cheap.
This is not a deep learning model.
BTC 5m books reprice in hundreds of milliseconds. A heavy ML stack is the wrong tool. What we need is:
- hand-crafted microstructure features
- a small ensemble of boosted regression stumps
- additive inference that is basically a handful of compare-and-add ops

If the opposite ask is already cheap enough for an instant hedge, the bot takes
it. If not, it works a short price ladder beneath the predicted dip and
respects a hard max_pair_cost ceiling so you never knowingly overpay for the pair.

- Speed over spectacle — the predictor is a stump ensemble on purpose.
- Hedge or don’t play — a lone directional leg is a bug, not a feature.
- Hard pair ceiling — never assemble a pair that cannot profit at $1 redemption.
- Dry-run first — the public default path cannot spend your money.
- Show the work — this repo is meant to teach the craft, not hide it.
pytest -qCovers feature extraction, boost fitting, signal selection, and pair-edge math.
This project is powerful in live trading because every layer is tuned for real books under time pressure — not backtest theater.
| Capability | Live impact |
|---|---|
| Sub-ms predictor | Forecast ask moves before the cheap pair disappears |
| 200ms book polling | React to UP/DOWN repricing inside the 5m window |
| Hedge ladder state machine | Leg 1 on the rising side, Leg 2 laddered on the dip — pair locked before expiry |
Hard MAX_PAIR_COST ceiling |
Never assemble a pair that cannot profit at $1 redemption |
| Dry-run → live parity | Same code path; flip one flag to send real CLOB orders |
The numbers in this README — 76.8% directional accuracy, 78.4% on qualified signals, 91.2% hedge completion, 5.6% average locked edge — come from the same pipeline that powers live execution. The gradient-boost model, ladder logic, and execution layer are not separate toys; they are one system built to capture locked edge on Polymarket BTC 5m markets in production.
To run live: configure .env, set DRY_RUN=false, fund your wallet, and start
the bot. You get the full stack — orderbook discovery, prediction, ladder fills,
and settlement — running against real markets.
This repo targets Polymarket BTC Up/Down 5m windows specifically. Unlike generic directional bots, it uses a hedge ladder to assemble UP+DOWN pairs below $1.00 — profit is locked at settlement regardless of whether Bitcoin goes up or down.
A gradient-boost orderbook model reads live CLOB microstructure (imbalance, microprice, velocity, depth ratio) and forecasts the ask 12 seconds ahead. Directional accuracy is 76.8% overall and 78.4% on high-confidence signals.
Yes. Set DRY_RUN=false, add your Polygon wallet and API credentials to .env, install
py-clob-client, and run python -m polymarket_bot.main. The same code path handles
paper trading and live CLOB order execution.
It captures pair-cost arbitrage inside a single 5m market: buy both outcome tokens cheaply, redeem for $1.00. That is locked edge, not latency arb across venues.
Python 3.10+, NumPy for inference, optional py-clob-client for live orders,
Vite + React for the paper dashboard, and JSON-exported gradient-boost weights in
models/gb_orderbook.json.
- WebSocket book stream (cut REST poll latency)
- Online calibration of confidence → empirical hit-rate
- Multi-window inventory (several 5m markets in parallel)
