Weather Trading Bot v3 — Polymarket
Auto-cycle + Forecast Monitoring + Kelly + EV
Two threads running in parallel:
- Entry thread: scans for new trades every 60 minutes
- Monitor thread: checks forecasts every 10 minutes, closes if EV goes negative
Usage:
python bot_v3.py # Start both threads (paper mode)
python bot_v3.py --live # Start both threads (live simulation)
python bot_v3.py --once # Run one scan and exit (no loop)
python bot_v3.py --positions
python bot_v3.py --reset
