About

Automatically generate Polymarket trading volume by placing offsetting BUY orders on both outcomes of balanced markets every 15 minutes. The bot searches for liquid, non-negRisk markets with balanced prices (YES between 15-85%), validates orderbook spreads are tight (<$0.10 combined), and places GTC limit orders on both sides. Risk-neutral by design — you hold both outcomes.

Quick Setup:

Choose the wallet to trade with (must have pUSD on Polygon)
Set your trade amount per side (default: $10)
Select a notification channel for trade confirmations
Test and publish!

Risk Controls:

Limit orders only (GTC, post-only) — won't fill at bad prices
Spread gate: skips if combined spread > $0.10
Price balance filter: only trades markets with YES price 15-85%
Minimum order size: 5 shares per side
Liquidity floor: $10k minimum on-book liquidity
