Blocksize’s Real-Time Bid/Ask Feed provides an accurate and continuously updated view of market liquidity, aggregating the best bid and ask prices across a broad selection of centralized and decentralized exchanges as well as producing the mid price. Designed for trading platforms, institutional desks, data vendors, and DeFi applications, this feed offers critical insight into price discovery, market depth, and spread dynamics with sub-second latency — all through unlimited WebSocket access.

Each data point is calculated by collecting order book updates across multiple exchanges and applying a volume-weighted averaging algorithm for both bid and ask sides. This ensures the most liquid venues exert greater influence on the final price, providing a more reliable indication of market value than single-source quotes. The resulting feed not only shows top-of-book prices but also reflects the effective trading cost (via spread width) and execution quality available across markets.

To guarantee data quality, Blocksize applies a statistical anomaly filter that dynamically adapts to trading activity. Using a liquidity-adjusted window, the system filters out sudden outliers that could otherwise distort bid or ask prices. In addition, if a significant price jump is detected, a built-in correction mechanism recalibrates the data window to ensure the feed remains responsive without misclassifying valid moves as anomalies.

This product is particularly valuable in low-liquidity markets where last-traded prices may not represent current market value. Traders can use the feed to price assets, optimize order routing, and assess volatility. Meanwhile, oracles, analytics platforms, and institutional clients benefit from clean, real-time insights into the most executable price levels in the market — with guaranteed uptime and consistent update frequency.
