15-Minute Up/Down Market Arbitrage with Configurable Hedge Thresholds

How It Works This bot continuously scans Polymarket's 15-minute directional crypto markets via the Gamma API, looking for mispricings where the combined YES+NO price deviates from fair value. When an arbitrage condition is detected (combined prices sum to less than 1.0 net of fees), the bot executes hedged trades to capture the discrepancy.

Entry / Exit Conditions Entry is based on configurable hedge thresholds — the bot only trades when the detected spread exceeds a user-set minimum to ensure profitability after fees. Risk management rules (likely position size limits and maximum concurrent positions) are described as 'integrated.' Exit is primarily at market resolution given the 15-minute duration.

Verification No backtested or live results are documented. The Gamma API integration is a verifiable technical detail, as Polymarket's Gamma API is the standard programmatic interface for market data and order execution.

Implementation Notes The repository has existed since March 2025, suggesting a longer development history than most bots in this report. Configurable thresholds imply parameter optimization is required by the user. Risk management integration is mentioned but not detailed.

Risks Same structural risks as other 15-minute arb strategies: execution latency, liquidity constraints, and slippage. The 'configurable hedge thresholds' require careful calibration — thresholds set too low will result in trades that are unprofitable after fees. Markets may update prices faster than the bot can execute.
