How Spread Detection Works
CLOB Orderbook Scanning
We fetch real best-ask prices from Polymarket's CLOB API for both YES and NO tokens of every active binary market.
Spread Calculation
Spread = YES_best_ask + NO_best_ask - 1.00. Any positive spread represents a market inefficiency. We flag spreads > 1%.
Edge Estimation
Estimated edge = spread minus ~2% fees. Positive edge after fees means the opportunity may be profitable to execute.
