Market data requirements depend on the need for adaptation, latency sensitivity and market depth. Differences in data contracts around the world can be both significant and subtle. The impact on policies and licences may not be immediately clear. EMDA is Euronext`s main market licensing agreement. Initially, individual financial data providers provided data for software applications in financial institutions specifically designed for a data stream. to give this financial data provider control of this activity. Then, many large investment banks and asset management companies began to design systems that would integrate market data into a central memory. This has encouraged investments in large enterprise data management systems, which collect, standardize and integrate flows from multiple financial data providers, with the aim of creating a ”one-sided version of the truth” of the data repository that supports all types of transactions across the institution. Beyond the operational efficiency gained, this convergence of data has become increasingly necessary to enable compliance with regulatory requirements such as Sarbanes Oxley, Regulation NMS and the Basel 2 agreement.  Typical use can be a feed-handler solution. Applications (sources) receive data from a particular stream and establish a connection with a server (Authority) that accepts customer connections (targets) and redistributes data. If a customer (target) wants to subscribe to an instrument (to open an instrument), it sends a request to the server (Authority) and if the server does not have the information in its cache, it transmits the requirement to the source or sources.
Each time a server (Authority) receives updates for an instrument, it sends them to all customers (targets) that have been subscribed.

The example above is an aggregation of different data sources, as supply data (supply, demand, supply size, supply size) and business data (last sale, final size, volume) are often generated by different data streams. Not only is market price data used in real time to make buying or selling decisions on the spot, but historical market data can also be used to project price trends and calculate market risk for asset portfolios that may be held by an individual or institutional investor. This presentation of the enumeration points is intended to provide a quick checklist of important points to watch for when auditing a market data contract. You want real-time market data and/or deferred market data to be redistributed to a third party (customers) Market data is expensive (global spending of more than $50 billion per year) and complex (data diversity, functionality, technology, billing).
