What Data Is Included in the OPRA Feed?
Nowadays, running the Options Price Reporting Authority (OPRA) reliably has become an operational challenge. OPRA is a consolidated SIP-style feed of U.S.-listed options quotes and trades across participant options exchanges. The problem in 2026 isn’t that firms can’t access the OPRA feed—it’s that bursty message rates are capable of overwhelming networks, processors, and downstream applications in milliseconds.
Think of OPRA as a firehose of information—an unpredictable, rushing flood of raw, unfiltered data that requires processing. Our previous article, “Options Market Data Costs: The Real Price of Running OPRA at Scale,” summarizes this concept fittingly:
“In options, every underlying expands into an entire surface of strikes, expirations, and calls/puts, and liquidity providers continuously update quotes across that surface as the underlying moves. With dense strike listings and frequent expirations, even modest moves can trigger a large number of quote updates across many related contracts. That is why options feeds—especially OPRA—behave like a firehose under volatility.”
This article breaks down what data is included in the OPRA feed: quotes, trades, and supporting administrative and summary data.
What Options Does OPRA Cover?
OPRA covers U.S.-listed equity options (e.g., single stocks, ETFs, index options) and can include more than a million active option series at a time. It’s the common, consolidated reference point for listed options activity—the standard reference point many firms use for pricing, monitoring, risk, and surveillance. OPRA remains the most widely used consolidated view of U.S.-listed options.
OPRA isn’t just one exchange’s data; it’s the market-wide framework that standardizes how consolidated options quotes and trades are collected from participating U.S. options exchanges and distributed to firms. At the application level, that information is often displayed in options chains.
What Core Data Elements Are Included in the OPRA Feed?
At a high level, OPRA delivers two things across the U.S.-listed options markets: quotes (bids/offers) and trades (last-sale reports). Most OPRA traffic is quoting, not trades, offering top-of-book visibility as opposed to full depth.
OPRA consolidates and disseminates exchange quotes—Best Bid and Offer (BBO), National Best Bid and Offer (NBBO), and last-sale information—across U.S.-listed options exchanges, including the best bid and best offer for a series, or what most teams think of as top of book/Level 1.
In practical terms, each quote update provides some combination of:
- Bid and offer price levels
- Size at those prices
- Venue attribution (which exchange the quote came from)
The core data elements of OPRA include:
- Last-sale reports, or prints that show that an option series traded, at what price, and in what size (with trade-related flags/conditions, depending on the message)
- Quotation information, such as NBBO
- Additional OPRA information, such as administrative and control messages, reference-style messages and end-of-day or summary-style information, and open interest
What Information Isn’t Included?
OPRA is meant to provide a consolidated baseline, not a full reconstruction of everything happening inside every exchange, meaning you won’t get the depth of book and venue-specific detail you would see in proprietary direct feeds. If a workflow depends on deeper order book detail or complex order visibility, firms often need direct exchange feeds in addition to OPRA.
Why is Access to OPRA Options Important Now?
Today’s financial markets are facing increasingly high message volume, volatility, and fragmentation—and OPRA is no exception. For firms consuming raw OPRA, processing the feed can require handling every update, whether or not every downstream system needs full tick-by-tick fidelity. Plus, as OPRA message volumes surge and rack space and power costs escalate across major data centers, raw OPRA access alone is no longer enough.
Plus, when markets move, options quote activity accelerates across an entire surface of strikes and expirations—so bursts are more common, not exceptional. Meanwhile, if your OPRA feed goes down, it’s a compliance issue because degradation can impact surveillance, monitoring, and best-execution controls across the firm.
On top of these shifts, OPRA’s 96-line symbol distribution schema became effective March 2, 2026, following industry testing and redistribution of traffic across the output lines. Redundancy amplifies the capacity problem because many firms take redundant production paths for fault tolerance, effectively increasing bandwidth and downstream handling requirements during peak conditions. The move to 96 lines did not reduce the underlying traffic burden, but it changed the delivery shape and forced firms to revalidate ingestion, processing, and downstream stability at peak rates.
In short, the challenge for firms today is staying stable when bursts hit and when OPRA changes its distribution rules. In fact, OPRA’s Dynamic Symbol Load Balancing is targeting Q4 2026 for launch, at which point firms will need to prove they can track distribution changes cleanly and stay stable when distribution shifts.
Which Options Market Data Feed Does Your Firm Need?
These updates may have you wondering which options market data feed your firm needs. Do you have the reliable connectivity and infrastructure to support and maintain necessary OPRA coverage? This decision will depend on whether you need proprietary direct feeds or OPRA.
Realistically, most firms don’t make a single, one-time choice for options market data—they build a feed set and decide how to deliver it by workflow. Though some systems truly need tick-by-tick updates, many don’t. The objective is to keep fidelity where it matters while keeping everything else stable during bursts. That is also the core framing of Exegy’s existing guidance on selecting options market data feeds.
A sensible way to decide between feeds is to evaluate the following four factors, then map each requirement to the workflows that actually use it.
- Latency sensitivity
- Cost (total cost, not just fees)
- Depth/granularity
- Complex order visibility
While OPRA remains a practical baseline for broad market visibility, ensuring fit-for-purpose workflows now matter more than ever.
How Can Firms Ensure Reliable OPRA Feed Access?
OPRA itself frames capacity planning around bursts, which means the “stress case” isn’t rare; it’s the design point. Connectivity needs and demands depend on a number of factors and vary widely by firm. Gaining adequate control over the firehose often necessitates working with a vendor to determine these requirements and implement infrastructure to support them. Exegy’s current options-feed guidance similarly emphasizes designing around bursts, not averages.
To process OPRA reliably, firms need a resilient, high-capacity platform built to withstand volume spikes. Exegy’s Axiom for OPRA helps firms shape and deliver data based on workflow needs, whether that means full-fidelity delivery for workflows that need every consolidated update or conflated and filtered views for systems that don’t need every tick. This fit-for-purpose approach can reduce downstream processing, rack space, and power costs while helping firms stay stable under peak message bursts.
