Market Data Feeds
Market data feeds are the continuous streams of electronic information that provide real-time or delayed pricing, volume, and trade details for financial instruments. In the context of cryptocurrency and derivatives, these feeds aggregate raw data from exchanges, decentralized liquidity pools, and order books to facilitate price discovery.
They serve as the foundational infrastructure for algorithmic trading, risk management, and portfolio valuation. Without these feeds, traders would lack the visibility necessary to execute orders or monitor the value of their positions.
These systems must prioritize low latency to ensure that the data reflects the most current market state, especially in volatile conditions. Market data feeds often include Level 1 data, which provides the best bid and ask prices, and Level 2 data, which offers deeper insight into the order book depth.
They are essential for calculating the Greeks in options trading and maintaining the integrity of margin engines. By consolidating information from fragmented global markets, they allow participants to make informed decisions based on accurate, up-to-the-second market conditions.
