## Market Data Feed Latency

Market data feed latency is the time gap between an event occurring on an exchange and the trader receiving the corresponding data update. This delay can be caused by the exchange's internal processing, the network transmission, or the client's own data parsing speed.

In high-speed trading, even a few milliseconds of latency can make a data feed obsolete. Traders must use efficient data protocols and optimized software to minimize this delay.

Some firms use dedicated, direct feeds from exchanges to avoid the congestion and overhead of public APIs. Monitoring and minimizing this latency is a continuous process of technical optimization.

It is a vital aspect of market microstructure that determines the quality of a trader's decision-making. If a trader's data is slower than the market, they are effectively trading on outdated information, which is a recipe for losses.

It is a core technical challenge in the digital asset domain.
