Market Data Feed
Real-time Market Data Distribution
Electronic systems delivering real-time price, volume, and trade information from exchanges to market participants.
Market data feeds provide continuous streams of trading information including bid/offer prices, trade executions, volume statistics, and market status updates. Feeds use various protocols including multicast UDP for high-speed distribution and TCP for reliable delivery. Different feed types serve varying needs from ultra-low latency feeds for high-frequency trading to delayed feeds for retail applications. Major exchanges operate proprietary feeds while vendors aggregate data from multiple sources. Feed processing requires sophisticated technology to handle massive data volumes, ensure data quality, and provide timely distribution. Regulatory requirements mandate fair access to market data while exchanges balance revenue generation with market access needs.
