\"Tiingo<\/p>\n

Overnight U.S. equity data used to be institutional-only. Starting today, anyone can get it, for $9 a month over their plan, which is at our cost.<\/em><\/p>\n

Exciting news! Today we’re launching the real-time Blue Ocean ATS API on Tiingo (the BOATS API): overnight stock prices for up to 12,000+ U.S. equities, delivered over REST and WebSockets. We’re the first to make this overnight U.S. equity data broadly accessible, and the first to make it available to individuals at all. The add-on is $9 a month, which is our cost ($8\/month BOATS license fee + $1\/month compliance and processing cost).<\/p>\n

What Blue Ocean ATS is, and what we now deliver<\/h2>\n

Blue Ocean ATS<\/a> (a.k.a BOATS) runs during the overnight U.S. equity trading session, and it’s the most dominant, liquid overnight venue for U.S. stocks. The session runs from 8:00 PM to 4:00 AM ET, Sunday through Thursday.<\/p>\n

A quick overview on terminology: because “overnight” data is new, consider it a separate set of hours than what’s typically called “after-hours”. After-hours extends the U.S. trading day (considered 4am-9:30am and 4pm-8pm). The overnight session is the stretch between that – the overnight hours of 8pm-4am ET. And if you trade from Asia or Europe, “overnight” is your daytime – which is why BOATS is beloved by Asian and European traders in addition to US.<\/p>\n

Tiingo now delivers, in real time, top-of-book quotes (bid, ask, mid) and the last trade with its size. Overnight intraday OHLC too. Coverage spans up to 12,000+ U.S. NMS equities quotable on Blue Ocean ATS, over both REST and WebSockets, through the same real-time equity formats you used to with our IEX Endpoints. There is no new integration to build. Full specs live on the Blue Ocean ATS (BOATS) product page<\/a>.<\/p>\n

One request to get data – easy.<\/h2>\n

With a simple GET request to the Blue Ocean API, you can get the instant overnight quote for any symbol quoted. Here’s SPCX:<\/p>\n

Leave the tickers list out and you get everything trading overnight. Add a few symbols if you want to limit the output (it’s a ton of data). That’s the entire getting-started path for the Blue Ocean API.<\/p>\n
Where to read the full docs<\/h2>\n
The Blue Ocean ATS API is documented end to end. Every field and every message type lives in the BOATS REST API docs<\/a> and the BOATS WebSocket API docs<\/a>. Grab your API token from your account page, and you can pull your first overnight quote in about two minutes.<\/p>\n
How this became available to individuals<\/h2>\n
Until now, this data was effectively enterprise-only. If you had a licensing team and a compliance department, you could get it. Individuals were often priced out; overnight market data started as institutional agreements, and individual access was a category that hadn’t been catered to yet.<\/p>\n
We reached out to the BOATS team – and to their amazing credit, they retooled their market data agreements to make this possible. Really big thank you to their team for taking a modern approach to data.<\/p>\n
Historically, what makes market data expensive is the licensing and the rules around it, not the bytes, so a venue actually reworking those rules to reach retail is an awesome move. This launch exists because of their approach to market data rules – and modernizing them as more people are able to access and process this data. On our side, we built the compliance layer, so a solo developer doesn’t need a compliance department to subscribe. Once you answer a few questions, we automate compliance on our end for you.<\/p>\n
Real-time overnight data existed. Now made accessible to all.<\/p>\n
How liquid is Blue Ocean ATS?<\/h2>\n
Given it’s an overnight exchange, we were surprised by the liquidity. From Blue Ocean market-data statistics for the overnight session of June 22, 2026:<\/p>\n

$9 a month. At cost.<\/h2>\n
The Blue Ocean add-on is $9 a month: $8 is Blue Ocean’s license fee, and $1 covers compliance processing. No Tiingo markup. We make essentially nothing on this, and it was important to me we make it that.<\/p>\n
What you need to run it: individuals need a Power plan ($30\/month) plus the $9 add-on, which comes to about $39 a month all-in. Businesses need a Commercial plan ($50\/month) plus the same $9. Enterprise and redistribution is a separate conversation, a $500\/month Tiingo fee plus a Blue Ocean license fee (contact sales@tiingo.com and we can make the introduction to the BOATS team).<\/p>\n
We’ve been making financial data accessible since 2014, and we’re the oldest accessible retail market-data API still around. This launch is that mission, not a new revenue line. Consider it a give-back. Full details live on the product page<\/a>.<\/p>\n
How to turn it on<\/h2>\n
    \n
  1. Go to your Tiingo account page<\/li>\n
  2. Open the Entitlements page<\/a><\/li>\n
  3. Fill out the short questionnaire<\/li>\n
  4. Start the add-on<\/li>\n<\/ol>\n
    You’re enabled immediately, the same day.<\/p>\n
    What’s next<\/h2>\n
    This is the first article in a series on overnight data. Article 2 gets into the mechanics: how the overnight session actually works and where orders get routed. Today is just the announcement. If you want the full landscape now – every overnight venue and which data feeds carry the session – our overnight stock data API<\/a> guide breaks it all down.<\/p>\n
    The overnight U.S. equity session is no longer something you need an institution behind you to see. It streams on the API you already use, in real time, for $9 over your plan. At cost. Because that’s the version of this industry we’ve been trying to build since 2014.<\/p>\n","protected":false},"excerpt":{"rendered":"
