Data licence and redistribution

A data licence is the agreement under which an exchange or vendor lets a subscriber receive market data for a defined use, on defined terms. Redistribution, the act of passing that data on to other people or products, is a separate right that a standard subscriber licence usually does not include.

What a licence actually grants

Exchange data is owned by the exchange. A vendor such as a broker or a data provider holds a distribution agreement and passes data to subscribers under an entitlement that names the exchange, the product group, the depth level and the subscriber category. Historical data is often a separate entitlement, and depth history is distinct from trade history. The application displaying the data is not the licensor; it consumes what the subscriber's own entitlement allows.

  • Non-professional versus professional status changes the fee and sometimes the permitted use.
  • Real-time, delayed and end-of-day data are separately priced.
  • A licence for display does not permit feeding the data to other users, publishing it or selling derived products.
  • Crypto exchanges publish public trade feeds, but their terms still govern commercial reuse and geographic access.

Why free footprint charts are not free data

A software vendor can offer a free tier or a demonstration, but it cannot include an exchange entitlement that the subscriber has not paid for. A website demonstration built on recorded or generated data teaches the notation without redistributing anything licensed. When a tool shows live futures for free, check whether the data is delayed, sampled, or coming through an account the user already pays for.

In Senzoukria

Market data is billed by the provider, not by the software. The Broker Connections screen measures the Databento licence on the user's own key and reports "Needs a live {dataset} licence on your Databento plan" when a dataset is not covered; the Databento source is described as market data only, no orders. The Binance Spot public feed is labelled as needing no account, no credentials and no data subscription, and crypto stays in analysis mode. Rithmic data depends on the market-data entitlement of the plant the account is on. None of these sources are redistributed by Senzoukria to other users; each subscriber connects with their own credentials, stored in the operating-system keychain.

Questions to ask before relying on a feed

  • Which exchange and product groups does my entitlement cover, and at what depth?
  • Am I classified as professional or non-professional, and does that change what I may do with the data?
  • Is historical trade data included, and is historical depth a separate item?
  • May I export the data, and under what conditions may I share exports?
  • Does a public API's terms of use allow the intended commercial use?

Frequently asked questions

Can I share exported tick data with another trader?
Usually not without a redistribution right. A subscriber licence typically covers your own display and analysis. Sharing raw exchange data with other people is a different category of use; check the exchange policy and the vendor agreement before doing so.
Does Senzoukria include market data in its subscription?
No. The software subscription and the market data are separate costs. Rithmic, Databento and exchange entitlements are billed by their providers under the subscriber's own account. Public crypto feeds need no subscription but remain subject to the exchange's terms.
Is delayed data free of licensing?
Delayed data is often cheaper or free to receive, but it is still licensed. Redistribution and commercial use remain governed by the exchange's policy. A delayed feed also changes what a footprint shows, so label it as delayed rather than live.
