Data partner or data vendor
What separates the data partner from the data vendor
Most vendors sample or compress the OPRA feed before you ever see it. algoseek captures every message and maps every contract through its corporate actions, so your history holds.

Questions teams ask before switching
-
What is the 60+ field minute bar?
Over 60 analytical fields per bar, derived from both trades and quotes: OHLC, underlying data, and volume analytics. The most comprehensive options minute bar available.
-
Does the data include Global Trading Hours?
Yes. SPX, VIX, and XSP options trade outside regular hours; algoseek captures those GTH sessions with dedicated datasets and the same normalization.
-
What does real-time streaming cost?
Real-time is $3,000 per month, delayed is $1,500, and package subscribers get 50% off. OPRA exchange licensing fees are separate.
-
Is the options security master proprietary?
Yes. Built and quality-controlled entirely in-house, mapping every OPRA contract through its full lifecycle. Most vendors do not have one.
-
How large is the OPRA feed?
Roughly 30 terabytes per day uncompressed. algoseek is one of the very few vendors that captures the full feed losslessly.
-
What is the difference between a dataset and a package?
A dataset is a single product; a package is every dataset for an asset class at one price. The US Options Package includes market data, reference data, and analytics, with new datasets added at no extra cost.
-
How far back does the US options data go?
Back to 2014, covering the full OPRA feed. Every expiration cycle and market stress period since, with expired contracts preserved.
-
Can I try the data before committing?
Yes. The Sandbox gives you up to a year of data via notebooks, SQL, Python, Excel, or download. No credit card required.
-
What delivery methods are available?
Historical: AWS S3 flat files, RESTful API, ArdaDB cloud SQL, notebooks, and Python. Streaming: TCP/IP to co-location, cloud, or over the internet.
One license, every OPRA dataset
The US Options Package
