Nasdaq’s first customer user acceptance test for the Nasdaq Options Market, or NOM, starts on Saturday, June 6, 2026. For most self-directed traders, this is not a trading signal. It is a market-structure and plumbing event. But it still matters because exchange technology changes can affect quote quality, order handling, and the data that brokers, charting platforms, and analytics vendors rely on.
The short version is that Nasdaq is moving NOM onto the same broad technology framework used across its other U.S. options venues. That brings renamed data feeds, two new proprietary feeds, more channel capacity, and new order-handling behavior for routed interest. The live symbol migration is scheduled to begin on July 27, 2026, not on June 6.

What is happening on June 6
June 6 is the first production-style customer UAT for the NOM re-platform. The deposited report cites Nasdaq Options Technical Update #2026-4, which says the test runs from 9:00 a.m. to 12:30 p.m. ET and makes all order-entry, quote, and market-data interfaces available in the re-platform environment.
The same update says Nasdaq planned test scenarios including:
- the opening process at 9:30 a.m. ET
- OPRA data updates for all test symbols
- a halt and re-open scenario in JD
- support for both legacy and re-platform connectivity during testing
That matters mostly for exchanges, market makers, brokers, vendors, and firms that consume proprietary feeds directly. For end traders, the significance is indirect: this is the test window for systems that shape displayed liquidity and downstream options analytics.
Confirmed changes in Nasdaq’s data-feed stack
Nasdaq Trader Data Technical News #2026-5 lays out the main feed changes tied to the re-platform.
Feed renames and content changes
The legacy BONO feed is being renamed the NOM Options Top of Market Feed. It will continue to provide best bid and offer information, but last-sale information is moving off that feed.
The legacy ITTO feed is being renamed the NOM Options Depth of Market Feed. Nasdaq says the updated version will provide full-depth, order-by-order messages, and subscribers will need to recreate the order book locally instead of relying on an exchange-built book.
Nasdaq is also adding two proprietary feeds, both pending SEC review:
- NOM Options Order Feed
- NOM Options Trade Feed
According to DTN #2026-5, the Order Feed will provide snapshots of resting orders plus auction notifications. The Trade Feed will carry last-sale information, cumulative volume, daily high and low data, and administrative or market-event messages.
More channels and higher bandwidth
Nasdaq says NOM currently distributes symbols across four multicast channels and will move to eight channels after the re-platform. The same notice gives projected peak bandwidth estimates of about:
- 2,114 Mb for the Top of Market Feed
- 2,324 Mb for the Depth of Market Feed
- 1,295 Mb for the Order Feed
- 1,076 Mb for the Trade Feed
These are exchange estimates, not guaranteed live rates, and they can vary with market conditions.
Protocol migration for participants
The deposited report cites Nasdaq’s FAQ and related technical updates showing that market participants are also dealing with protocol changes around the re-platform. In practical terms, firms that quote or enter orders directly on NOM may need to support newer OTTO, SQF, CTI, and FIX connections as symbols move over.
Nasdaq’s published migration materials also say legacy and new connections will overlap during the transition window, which reduces cutover risk but increases operational complexity.
Timeline traders should keep straight
The biggest date mistake to avoid is assuming June 6 is the live rollout. It is not.
Based on Nasdaq’s re-platform timeline and migration notices:
- June 6, 2026: first customer production test
- July 11, 2026: second customer production test
- July 25, 2026: final confidence test
- July 27, 2026: first symbol migration wave begins
- August 10, 2026: final symbol migration wave completes
The deposited report cites Options Trader Alert #2026-12 for the first migration wave. That notice lists 26 symbols for July 27, including AVGO, GOOG, HOOD, IWM, MSFT, SMCI, UBER, WMT, and XLE.
Why this matters for options traders
Most traders will never subscribe to a proprietary NOM feed directly. Even so, exchange feed changes can matter in three practical ways.
1. Quote quality and displayed depth may look different
When an exchange shifts to order-by-order depth and pushes more book reconstruction onto downstream consumers, vendors and brokers have to process that data correctly. If they do it well, nothing obvious changes for you. If they do not, book depth, last-sale display, or auction-related analytics can lag or appear inconsistent across platforms.
That is one reason understanding options volume vs open interest and what open interest means still matters: a platform display is only as good as the market-data pipeline behind it.
2. Order handling is becoming more harmonized across Nasdaq options venues
Nasdaq’s FAQ says re-platformed NOM symbols will introduce a 100 millisecond route timer for orders that would otherwise lock or cross away markets. The exchange describes this as order exposure before routing.
That does not mean every retail order is delayed by 100 milliseconds. It means certain routable orders may be exposed briefly on NOM before being sent away, giving local participants a chance to interact first. For traders, the important takeaway is not to over-read one print or one quote flicker during the transition. Execution quality should be judged over a broader sample, not from a single anecdote.
If you want a refresher on how venue mechanics affect fills, common options trading mistakes and how to avoid them is the relevant internal primer.
3. Migration periods can create temporary monitoring risk
During the July to August symbol migration window, firms may need to watch both legacy and new connectivity paths. The deposited report cites Nasdaq materials saying proprietary market data for migrated symbols will only be available on the new platform interfaces, while non-migrated symbols remain on legacy paths until their turn.
For traders, that creates more chance of platform-side hiccups than thesis-side opportunity. The higher risk is operational noise, not some automatic bullish or bearish signal from options flow.
Confirmed facts vs interpretation
Confirmed facts
- Nasdaq scheduled the first NOM re-platform customer production test for June 6, 2026.
- Nasdaq says BONO becomes the NOM Top of Market Feed and ITTO becomes the NOM Depth of Market Feed.
- Nasdaq says the Depth feed will include full-depth, order-by-order messages and subscribers will need to build the book locally.
- Nasdaq plans to add separate Order and Trade feeds, pending SEC review.
- Nasdaq says symbols will move from four multicast channels to eight.
- Nasdaq’s public migration timeline says live symbol migration starts on July 27, 2026 and completes on August 10, 2026.
Interpretation
- The main near-term impact for self-directed traders is better understood as operational and data-quality risk than as directional market insight.
- Larger firms are generally better positioned to absorb added feed, bandwidth, and testing complexity than smaller vendors or independent infrastructure users.
- If brokers or analytics tools handle the migration cleanly, many retail traders may notice little or nothing at all.
Common misunderstandings and caveats
One common mistake is treating exchange-technology upgrades as if they directly predict where a stock or ETF will trade next. They do not. A feed migration can affect how liquidity is displayed or how routing is processed, but it does not tell you whether a name is bullish or bearish.
Another mistake is assuming a UAT date equals a production launch date. In this case, June 6 is a test date. The live migration starts later, with the first symbol wave on July 27.
A third mistake is reading more into proprietary feed changes than is warranted. For most traders, the practical question is whether their broker or analytics platform continues to show clean quotes, prints, and volume data during the cutover window.
What to watch into the live migration
Between now and the July 27 first migration wave, the useful checkpoints are straightforward:
- whether Nasdaq updates any bandwidth, IP, or testing details
- whether the SEC review changes the proposed Order Feed or Trade Feed terms
- whether brokers or data vendors communicate platform-specific readiness for NOM changes
- whether quote, depth, or last-sale displays look inconsistent across platforms during migrated symbols’ early days
That is a monitoring checklist, not a trade setup.
Bottom line
Nasdaq’s June 6 NOM re-platform UAT is a meaningful infrastructure milestone for the options ecosystem, especially for firms that rely on direct proprietary data and exchange connectivity. For self-directed traders, the event matters less as an alpha signal and more as a reminder to treat options market data as market infrastructure that can change underneath the screen.
If the transition is smooth, the change may be barely visible from a retail front end. If it is messy, the first signs are more likely to show up in quote consistency, depth displays, and execution monitoring than in any clean directional read from options activity.
