Market data

Market dataRelevance for the financial market and the economy

How are market data generated and who uses them for which purpose? Find out how market data are generated by means of an elaborate process that is organised, operated and monitored by exchanges.


We live in a data age. This development also holds true for financial markets: every day, exchanges provide billions of pieces of information. Deutsche Börse Group alone makes up to 4 billion pieces of information available worldwide in real time every day – and counting.
The high quality and reliability of these market data are particularly important for customers. Reliable and valid market data form the very basis of a transparent, informed decision-making process and are decisive for fair competition in financial markets.  

Market data and its generation and publication by stock exchanges are subject to a legal framework and oversight by supervisory authorities. This is regulated uniformly in the EU in accordance with the European financial market regulation MiFID II/MiFIR.
A key objective of these regulations is to promote transparency of the financial markets and competition.
