Polymarket Analyzer
Scans Polymarket prediction markets for trading edges using their public APIs. The four scripts cover the basics: finding arbitrage (when YES + NO prices don't sum to $1), analyzing order book depth to see if an edge is actually tradable, detecting volume and price momentum, and tracking correlated exposure across your positions. No authentication needed since it's all read-only analysis. The fee awareness is solid, especially the note about dynamic fees on crypto short-term markets. Honest about limitations and includes a reference doc on strategies that still work. If you're actively trading prediction markets or just curious about market inefficiencies, this gives you the scanning infrastructure without having to write it yourself.

Available Scripts
1. Find Arbitrage Edges (scripts/find_edges.py)
Scans all active markets for pricing inefficiencies:
- Underpriced: YES + NO < $1.00 (guaranteed profit if you buy both sides)
- Overpriced: YES + NO > $1.02 (sell opportunity)
- Calculates profit after fees for each opportunity
- Outputs market name, prices, sum, potential profit, and fee impact
python scripts/find_edges.py
python scripts/find_edges.py --min-edge 0.02 --limit 500
2. Analyze Order Book (scripts/analyze_orderbook.py)
Deep analysis of a single market's order book:
- Spread, mid-price, bid/ask depth (top N levels)
- Bid-ask imbalance ratio (signals directional pressure)
- Thin vs thick book classification
- Liquidity concentration analysis
python scripts/analyze_orderbook.py --token-id <TOKEN_ID>
python scripts/analyze_orderbook.py --token-id <TOKEN_ID> --depth 10
3. Momentum Scanner (scripts/momentum_scanner.py)
