modbender Polymarket AutoTrader (Premium)
BTC 5-minute prediction auto-trading bot — 92%+ historical win rate, 5-8% profit per trade, fully automated.
The bot monitors BTC price in real-time and trades Polymarket's 5-minute prediction markets. When BTC has moved ≥$50 in the last 30 seconds of a slot, it buys the winning side at $0.92-0.95. Winning shares pay $1.00 — that's 5-8% profit per correct trade. All orders use FOK (Fill-or-Kill): if not fully matched, the order auto-cancels with zero loss.
| Metric | Value |
|---|---|
| Historical win rate | >92% (with $50+ signal) |
| Profit per trade | 5.3-8.7% ($0.92-0.95 entry → $1.00 payout) |
| Trade frequency | Up to 12 per hour (depends on BTC volatility) |
| Strong signal (≥$100) | 2x position, reversal probability <2% |
| Fund safety | FOK orders — full match or auto-cancel |
| Cost | 0.001 USDT per trade (built-in billing) |
⚠️ Security Notice
- Use a DEDICATED Polygon wallet with limited funds. Do NOT use your main wallet.
- Run in an isolated environment (Docker/VM recommended).
- Review the source code (
scripts/bot.js) before running. - The bot writes
.poly-creds.json(derived API credentials, sensitive) andtrades.json(trade log) locally.

How It Works
- Monitor (0–270s): Track BTC price vs. 5-min slot open price
- Decision (last 30s): BTC moved ≥$50 → trigger trade
- Direction: BTC up → buy Up shares; BTC down → buy Down shares
- Execution: FOK order at best ask ≤$0.95
- Settlement: Polymarket auto-settles — winners get $1.00/share
Why it works: When BTC already moved $50+ with only 30 seconds left, full reversal probability is <5%. We buy at $0.92-0.95, win pays $1.00.
