Electronic Communication Networks
Electronic Communication Networks (ECNs) are automated trading systems that match buy and sell orders for securities electronically without a traditional broker-dealer intermediary. They provide direct access to market participants, enabling faster and more efficient execution of trades, often with lower transaction costs. ECNs are widely used in financial markets, particularly for equities, options, and foreign exchange.
Developers should learn about ECNs when working on financial technology (fintech) applications, algorithmic trading systems, or market data platforms, as they are critical for high-frequency trading and real-time order matching. Understanding ECNs is essential for building low-latency trading engines, implementing order routing logic, and ensuring regulatory compliance in electronic markets.
