Market data latency refers to the time delay between a trade or price change occurring on an exchange and the corresponding data being received by a trading system. In high-frequency trading, minimizing latency is paramount for maintaining a competitive edge. Low latency enables algorithms to react faster to market movements, capturing fleeting arbitrage opportunities before other participants.
Impact
The impact of latency on derivatives trading is significant, particularly in options pricing and risk management. High latency can lead to stale price feeds, causing pricing models to generate inaccurate valuations. This discrepancy creates risk for market makers and can result in adverse selection when executing trades.
Execution
Latency directly affects trade execution quality, especially for automated strategies operating in fragmented cryptocurrency markets. A delay in receiving market data can cause orders to be filled at prices different from the intended entry point, resulting in slippage. Efficient execution requires robust infrastructure designed to minimize data transmission time.
