This article explains the types of market data solutions we can provide. Read the companion article to find out why a company would want to partner with us to license market data.  

Who is Intrinio?

We’re a full-service financial data and data technology partner for businesses. We offer solutions across numerous providers, delivery mechanisms, and data types with world-class technology and support.  

What is market data?

Market data includes prices and trade-related data for securities. Stock prices are the most common form of market data; however, even basic stock prices can come from exchanges across the globe in real-time, end of day, delayed, and other formats. Market data also includes options.

Our Market Data

Here are the types of data we can provide through our platform:

Real-Time Snap and Streaming Equity Prices

Real-time snap and streaming equity prices are essential for driving trading decisions, creating buy and sell sentiment, and powering trade execution platforms.

What’s included:

  • Bid price and size
  • Ask price and size
  • Timestamp
  • Last sale
  • Market volume
  • Open, high, and low

Delivery methods: WebSocket API, Web API

What to know: Data from a single exchange will have “drift” from the National Best Bid and Offer (NBBO) across all exchanges. A higher-volume exchange, such as NASDAQ, has less drift than a lower-volume exchange like IEX.

How Intrinio helps: Intrinio's new real-time Multi-Exchange equity feed combines data from the IEX and MEMX exchanges for higher liquidity (6%+) and better accuracy. This feed also has no exchange fees, no per-user fees, and little to no paperwork.

Integrating real-time data is also a serious challenge for businesses. We provide SDKs, technical consulting and implementation help, third-party coordination, a built-in ticketing system for technical and data quality issues, and account management to simplify the process.

15-Minute Delayed Snap Equity Prices

Businesses that need to display pricing data on their platform or website can gain huge cost savings by using 15-minute delayed pricing data.

What’s included:

  • Bid price and size
  • Ask price and size
  • Timestamp
  • Last sale
  • Market volume
  • Open, high, and low

Delivery method: Web API

What to know: Unless your company requires real-time data, we recommend a delayed feed as it is less expensive. For most delayed datasets, there are also no exchange reporting requirements or variable per-user fees associated, which require sophisticated entitlement systems to maintain.

How Intrinio helps: We’ll recommend the best 15-minute delayed solution based on your specifications and help you navigate the process of working with different exchanges.

Real-Time and Delayed Options Prices

Our filtered US options feed provides NBBO quotes and all trades from the Options Price Reporting Authority (OPRA) without sacrificing data quality.

What’s included:

  • Greeks (delta, gamma, theta, and vega)
  • Implied volatility
  • Unusual options activity (blocks and sweeps)
  • Last trade price, size, and timestamp
  • Total trade volume
  • Last ask/bid price, size, and timestamp
  • Underlying symbol
  • Put or call
  • Expiration date
  • Strike price
  • Exercise style
  • Open interest

Delivery methods: Web API

History: None

What to know: We recommend starting with a 15-minute delayed trial feed. This option has no exchange fees for internal use, and we waive any licensing fees during the testing period. Upgrading to real-time options from the delayed feed is simple; the connection to the OPRA exchange is identical and our experts will help facilitate all exchange paperwork.  

How Intrinio helps: Options are complex with hundreds – or even thousands – of contracts and expiration dates for a given security. Our filtered options feed reduces bandwidth up to 80% by eliminating unactionable data while still delivering all trades and NBBO quotes.
