T7 Enhanced Market Data Interface (EMDI)
Quick definition
The T7 Enhanced Market Data Interface (EMDI) is a market data feed offered by Deutsche Börse on venues based on its T7 exchange trading platform, such as Xetra, Eurex, EEX, and the Nodal Exchange.
What is T7 Enhanced Market Data Interface (EMDI)?
EMDI is a market by price (MBP) feed, which exposes aggregated depth at limited price levels, providing lower granularity than EOBI.
Updates on EMDI are un-netted, meaning that they are provided for every order book change that affects the price levels in scope. This is unlike the T7 MDI feed, which is netted (conflated) and only publishes updates at regular intervals.
