OpenBB Nasdaq Provider

This extension integrates the Nasdaq data into the OpenBB Platform.

Every dataset is read from the public Nasdaq website API. No API key or account is required.

This extension is not affiliated with, endorsed by, or authorized by Nasdaq, Inc.

Installation

Install from PyPI:

pip install openbb-nasdaq

Or from the source tree:

uv pip install -e openbb_platform/providers/nasdaq

Then rebuild the Python interface:

import openbb

openbb.build()

Coverage

Nasdaq publishes far more than US equities. This extension covers the US market activity API, the Nasdaq Nordic and Baltic markets, and the Morningstar fundamentals Nasdaq co-brands for Nordic listings.

Notes on the data

Asset classes are resolved behind the scenes. Nasdaq keys most endpoints by an asset class (stocks, etf, index, mutualfunds, crypto). You pass a symbol; the extension resolves the class from the listing directory, falling back to a probe only for symbols the directory does not carry.

The same applies to Nasdaq Nordic, where instruments are keyed by an opaque orderbook ID and an asset class. Every listing is indexed once per process into a single directory of roughly 17,800 instruments, so the symbol alone resolves both. Nasdaq refuses pages under load by returning them empty rather than erroring, so a page that comes back empty when the listing claims more is retried - otherwise the directory would silently come up short.

etf.holdings covers mutual funds too. ETFs are served from the company holdings endpoint and mutual funds from the fund profile.

Options chains carry the full detail. Nasdaq's chain endpoint publishes only last, change, bid, ask, volume, and open interest, and its greeks endpoint is locked to the front expiration. The remaining fields - open, high, low, previous close, sizes, contract high and low, tick, market, and the greeks for every expiration - come from the per-strike contract endpoint, which is fanned out with bounded concurrency and retried on refusal.

Some Nordic data is only on the page. The trading hours and the exchange holiday calendar are published as server-rendered tables, not through an API, so they are read out of the markup.

Nordic fundamentals come from a PDF. The JSON sections Nasdaq exposes for Morningstar fundamentals return empty. The data is published only in the co-branded fact sheet, which this extension parses from glyph positions - the two-column layout interleaves the reading order, so plain text extraction is unusable.

Responses are cached on disk. A SQLite-backed HTTP cache holds responses with a TTL per endpoint family - sixty seconds for quotes and movers, up to a day for statements and filings - so a repeat options chain does not re-fetch thousands of unchanged contracts.

Standalone usage

The extension registers its own router, so installing openbb-nasdaq alone still exposes every dataset under /nasdaq. Each namespace registers its model-backed commands only when the OpenBB extension that normally owns those standard models is absent; when openbb-equity is installed, for example, the equity models are served through it instead and Nasdaq's own routes step aside.

The fetchers can also be used directly, independent of the Python and API interfaces:

from openbb_nasdaq import nasdaq_provider

nasdaq_provider.fetcher_dict

OpenBB Workspace

A bundled dashboard is served at /api/v1/nasdaq/apps.json, with the widget IDs resolved against whichever extensions are installed. Start the API and add it as a Workspace backend:

openbb-api

The app carries tabs for earnings, dividends, calendars, the economy, screeners, options, funds, indexes, and the Nordic markets. Clicking a symbol in a screener, mover, or snapshot table drives the linked widgets in that tab.

Development

uv pip install -e '.'
uv pip install --group dev
pytest tests --cov=openbb_nasdaq --cov-report=term-missing

The unit suite runs entirely offline - no cassettes and no network. Integration tests hit the live endpoints and are excluded by default:

pytest integration -m integration
