Network Latency
Network latency is the time delay between the transmission of a data packet and its reception at the destination. In trading, this refers to the time it takes for an order to travel from the trader's server to the exchange's matching engine.
Even a few milliseconds of latency can mean the difference between a successful trade and a missed opportunity. This delay is influenced by physical distance, network congestion, and the quality of the communication infrastructure.
To combat this, traders invest in high-speed fiber optics and optimized network protocols. Reducing latency is a constant battle against the laws of physics and the limitations of existing telecommunications.
It is a defining characteristic of modern electronic trading and a major driver of infrastructure investment. Managing this variable is crucial for any strategy that relies on speed.
