Provider data

Give your traders charts and quotes without building a feed. Some providers license their market data to each user. When a trader links a login you issued them at one of those providers, trdrs builds their market-data connection from that login, so bars, history and quotes stream under the trader’s own subscription and entitlements. trdrs redistributes nothing, which is why no data-vendor agreement sits between your venue and a working chart. This page is for venues whose traders hold accounts at a provider whose market data is licensed to each user. Today that’s Rithmic, and Providers keeps the current list. The page explains what you do, what trdrs does with the login, and when to publish your own feed instead.

​

Set it up

1. Issue the login at the provider with the market-data entitlements your traders should have. It’s the same decision you already make there.
2. Pre-register the account so the trader finds it waiting in Connect when they sign in.

That’s the whole integration. The trader links the account with their own login, and their charts stream.

​

Know what trdrs does with the login

• One data connection per trader. trdrs builds it from the trader’s own stored login. A trader with accounts at several venues streams from one of their logins, and if that login is disconnected, the next request rebuilds from a login that remains.
• Bars and quotes kept apart. Bars and history use one connection and live quotes use a second, so a login without a quote entitlement still charts bars.
• The provider’s session rules hold. Where a provider allows one live session per login, the application that signs in last takes the session. trdrs reconnects once, and if the session is taken again it stops rather than fight the other application for it. Each provider’s entry on Providers states its own rule.

​

Choose a published feed instead

Provider data covers markets your traders already reach through their provider login. For data trdrs doesn’t connect to, such as your venue’s own index or a market trdrs doesn’t carry, run a small HTTP feed and register it with trdrs: Publish a datafeed. Start with provider data and reach for a published feed second. A published feed is a server your venue keeps running, while provider data rides on a decision you already make at your provider.
