Market Data Refresh Rates

Market data refresh rates dictate how often the exchange updates the price information sent to traders. High refresh rates provide a more accurate and current view of the market, which is crucial for algorithmic trading and risk management.

However, high rates also increase the amount of data transmitted, which can strain both the exchange's servers and the trader's network connection. If the refresh rate is too slow, traders are operating on stale data, which increases the risk of adverse selection and slippage.

Finding the optimal balance between data granularity and system performance is a constant trade-off in the design of financial exchange interfaces.
