After months of live deployment with real pUSD, here’s the exact architecture behind a consistently profitable 5-minute prediction-market bot on Polymarket.
Core Alpha: Chainlink-Aware Dual-Phase Probability Edge
Every 5-minute Up/Down contract prices in crowd-implied probability (0–100¢).
Each YES share pays exactly $1 if the final Chainlink BTC/USD price ≥ starting price at expiry.
The edge is simple in theory, brutal in practice:
edge = p_model(true Up) − p_market
Trade only when edge exceeds threshold after spread + expected slippage.
One model cannot dominate both legs, so the system runs two surgically separated calibrated classifiers.
Phase 1 — Momentum Scalp (T-35s → T-6s)
Continuation regime.
Features (real-time):
- 1s / 3s / 10s BTC returns
- Full order-book imbalance & microprice
- Realized volatility
- Coinbase ↔ Chainlink price gap
Model: Logistic regression + calibrated tree ensemble → well-calibrated p_up.
Entry only on fat edge that survives early mean-reversion risk.
Exits are deliberately brutal:
- ~10¢ take-profit
- Hard stop-loss
- Mandatory flatten at T-6s (no hero holds)
Phase 2 — Last-Second Reversal Sniper (T-5s → T-0.5s)
Completely different regime: exhaustion + oracle dislocation.
Signals:
- Reversal probability
- Widening Coinbase–Chainlink gap
- Book thinning + aggressor flow
- Quote pressure
Strict execution rules:
- IOC only
- Smaller size
- Zero resting orders
- No last-tick prayers
Shared Production Infrastructure
- Polymarket CLOB + trades (new unified SDK)
- Coinbase WebSocket (price + full imbalance)
- Live oracle-gap monitor (RTDS vs proxy)
- Risk engine: per-trade caps, PnL stops, time-kill switches, one-click global kill-switch
- Smart order router: GTC in Phase 1 → IOC/FOK in Phase 2
- Tick-by-tick logger → perfect replay/backtest loop
Models are two independent calibrated classifiers:
- Phase 1 loves momentum + vol
- Phase 2 loves spreads + gaps
Both output clean probabilities you can subtract directly from market price — no accuracy cope, only edge.
Build Order That Actually Worked
- Ingestion + nanosecond timestamp sync
- Feature pipeline (BTC + book + oracle)
- Dual probability models
- Risk + forced exits
- Phase-aware order router
- Replay → paper → live (with alerts + kill-switch)
Result: consistent small edges compounded across dozens of 5-minute cycles per day.
The crowd treats these markets like coin flips.
The oracle + phase split + surgical exits turn them into high-frequency statistical arbitrage with deterministic settlement.
This isn’t “trading crypto.”
This is HFT-style microstructure arbitrage on the cleanest prediction market on the internet right now.
