In the FIX (Financial Information eXchange) protocol, the Market Data Incremental Refresh message (MsgType = X) is used to provide incremental updates to a subscriber in response to a Market Data Request (35=V) message. This message is typically used in real-time market data feeds to relay changes in market prices, trade volumes, and other relevant information for subscribed financial instruments.

Usage

The Market Data Incremental Refresh message is used by market data providers to send incremental updates for subscribed financial instruments in response to a Market Data Request message. It allows subscribers to receive real-time updates on changes in market prices, trade volumes, and other relevant information.

Market data providers send Market Data Incremental Refresh messages continuously or periodically as new market data becomes available. Subscribers use these updates to maintain an accurate view of the market and make informed trading decisions.

Market Data Incremental Refresh messages are essential components of real-time market data feeds used by trading platforms, algorithmic trading systems, risk management tools, and other financial applications.
