market data licensing
market data licensing is exchange market data is contract-licensed per client category rather than sold off-the-shelf: Euronext orders products through MyMarketData under EMDA/EDSA agreements with unit-of-count limits and audits. In Datadory's catalog of 1,744 datasets, Euronext - and LSEG - are working examples.
What is market data licensing?
Exchange market data is contract-licensed per client category rather than sold off-the-shelf: Euronext orders products through MyMarketData under EMDA/EDSA agreements with unit-of-count limits and audits.
From 1 October 2026 its pricing moves to ESMA's Reasonable Commercial Basis cost-based rates.
In this catalog it appears concretely: - Euronext - — "All Euronext market data is licence-based". - LSEG - — "Proprietary LSEG commercial licence agreements (exchange and vendor data entitlements)".
LSEG - is the second reference point worth knowing: "Proprietary LSEG commercial licence agreements (exchange and vendor data entitlements)". Reading the two together shows how much variation sits underneath one shared label.
Why does market data licensing matter when choosing a dataset?
License language decides what you may ship to customers. Misreading it has ended product launches, and the gap between free to view and free to redistribute is where most of those failures begin.
The failure mode is concrete: a source can carry the market data licensing label while differing from what you need on exactly the dimension that matters — From 1 October 2026 pricing moves to RCB cost-based rates with a reasonable margin, client-category assignment, limits on units of count and audit policies. Comparing two sources on that line usually settles the choice faster than any feature matrix.
You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and Euronext - lets you inspect the real artifact before any budget is committed.
How do you evaluate market data licensing in a data source?
Treat every claim of this attribute as testable:
- Open Euronext - and confirm its record — "All Euronext market data is licence-based" — against the files you actually receive.
- Open LSEG - and confirm its record — "Proprietary LSEG commercial licence agreements (exchange and vendor data entitlements)" — against the files you actually receive.

Frequently asked questions
What is an example of market data licensing?
Euronext - is the clearest example in this catalog. Its record states: "All Euronext market data is licence-based". Across all 1,744 datasets Datadory averages a quality score of 7.81 out of 10, so a named example can be weighed rather than trusted blindly.
Is data described as "market data licensing" free to use?
Treat access and permission separately. 82.4% of the 1,744 datasets in this catalog are free to access, but 235 are freemium and 61 are paid outright, so confirm both the price and the license on the exact distribution before building on it.
How do I verify a source really provides market data licensing?
Open Euronext - next to LSEG - and compare the promise with the download. Field definitions are verified for 1495 of 1,744 datasets (85.7%), which makes that check fast inside the catalog and manual outside it.
