The bot is a focused directional player on Polymarket’s BTC 5-minute Up/Down markets.
Unlike convergence farmers who snipe 94–99¢ near-certain outcomes, this system operates in the coin-flip band (~45–55¢) with a calibrated edge that pushes resolved win rate to ~60.7%.
Here’s a technical breakdown based on the public README and observable behavior.
Core Strategy
For each active BTC 5m Up/Down slot:
- Generate a directional read using CEX lead-lag, flow, momentum, and time-in-slot signals (private alpha).
- If the edge clears threshold and ask is in the fair ~50¢ zone → taker buy the favored side in $50–$175 clips.
- Monitor conviction throughout the slot.
- Scratch (sell ~breakeven) low-conviction positions.
- Hold to resolution only high-conviction legs.
This hybrid of directional forecasting + active risk culling turns a near-50/50 market into a positive expectancy book.
Measured Performance (Public Sample)
| Metric | Value |
|---|---|
| Held-side win rate (resolved) | 60.7% |
| ROI on staked capital (sample) | ~+24.5% |
| Avg entry on held legs | ~0.50 |
| Trades in sample | ~5,000 |
| Buy:Sell ratio | ~73:27 (active scratches) |
The system spreads entries across the slot (median ~47s after open) to source liquidity without lifting the book too aggressively.
System Pipeline
The logical flow per slot:
- Signal Layer — Private micro-forecast for P(Up) over the next 5 minutes.
- Entry Layer — If |P(Up) - 0.5| clears threshold and ask is attractive → accumulate.
- Conviction Cull Layer — Re-score every 10–30s. Scratch decaying signals at ~breakeven.
- Resolution Layer — Redeem winning shares only.
This architecture avoids the fee drag of pure convergence farming while maintaining a real edge through better-than-random directional accuracy.
Key Technical Considerations for Implementation
- Latency & Fill Quality — Early-slot liquidity at ~50¢ is key. Aggressive caching and reactive WebSocket handling are essential.
- Scratch Logic — Implementing reliable breakeven exits requires deep order books and careful timing.
- Risk Management — Per-slot caps, global exposure limits, and drawdown circuit breakers are non-negotiable.
- Data Feeds — CEX tickers, Polymarket CLOB, Gamma API for slot metadata, and oracle resolution events.
Why This Archetype is Interesting
Most short-horizon crypto prediction markets are treated as noise. A well-calibrated directional system that can consistently beat 50/50 on the held side (while scratching weak tickets) represents a different — and potentially more sustainable — approach than pure volume farming.
The repo itself serves as proof of authorship and strategy documentation rather than a full open-source drop, which makes sense given the alpha in the signal.
Takeaways for Bot Builders
- Focus on signal quality over execution complexity.
- Active conviction management (scratching) can dramatically improve outcomes.
- Mid-band directional trading (~50¢) can be less fee-sensitive than late-game convergence.
- Public API samples + profile data provide enough transparency for verification without revealing core IP.
If you’re building prediction market automation, studying focused directional systems like this one is well worth your time.
