openbb-hkex

OpenBB Platform provider extension for Hong Kong Exchange open data.

No API key needed — wraps the public hkexwidget JSONP endpoints, the daily ListOfSecurities.xlsx master file, and the hkexnews.hk disclosure search.

Every command lives under its own obb.hkex.* namespace. The extension never injects into the shared OpenBB namespaces (equity / index / derivatives), so installing it alongside other providers is safe and collision-free.

Install

pip install -e .
openbb-build   # only required for the Python `obb.` interface

What you get

All commands are under obb.hkex.*:

from openbb import obb

# Securities — reference, quote, profile, OHLCV (works for stocks, ETFs, REITs)
obb.hkex.search("tencent")                                   # search by name or code
obb.hkex.quote("00005")                                      # live quote (HSBC)
obb.hkex.info("00700")                                       # profile & listing details
obb.hkex.historical("00700", start_date="2026-04-01")        # daily OHLCV

# Indices — Hang Seng family + Stock Connect benchmarks
obb.hkex.index_snapshots(region="hk")                        # current index levels
obb.hkex.index_constituents("HSI")                           # constituents & weights

# Derivatives
obb.hkex.options_chains("HSI")                               # full chain, all expiries
obb.hkex.options_chains("TCH")                               # single-stock options (Tencent)
obb.hkex.futures_curve("HSI")                                # term structure
obb.hkex.futures_instruments("HSI")                          # listed contracts & metadata

# ETFs (use the HK-listed ETF code, e.g. 03037 = CSOP Hang Seng Index ETF)
obb.hkex.etf_holdings("03037")
obb.hkex.etf_nav("03037")
obb.hkex.etf_performance("03037")
obb.hkex.etf_tracking("03037")

# Reference & market structure
obb.hkex.securities_master(category="Real Estate Investment Trusts")
obb.hkex.securities_master(code="00700")
obb.hkex.derivative_products(category="Equity-Index")
obb.hkex.stock_derivatives(kind="options")                   # SSO ticker roster
obb.hkex.market_statistics(group_by="venue")                 # listed-universe aggregates

Symbol conventions

Run obb.hkex.derivative_products() or obb.hkex.stock_derivatives() to look up codes.

Why HKEX is awkward (gotchas the extension handles for you)

• Token: the widget endpoints 403 without a callback= param and a session token scraped from any market-data HTML page. The token rotates and arrives pre-URL-encoded. Cached for 1h, auto-refreshed.
• Option chains: the API only returns 11 ATM strikes unless you pass fr/to within each expiry's listed strike range. OptionsChains probes every listed expiry, discovers each range, then fetches the full chain.
• Disclosure search: hkexnews is JSF-driven and needs a session cookie jar. The included template (/search/titleSearchSearchPanel.html) defines the real POST field names; the inline form on the visible page does not.
• Stock options ≠ stock code: SSOs/SSFs use a 3-letter HKEX ticker (e.g. TCH for Tencent), not the 5-digit code. Use stock_derivatives to map.

OpenBB Workspace

The extension's router also serves the HKEX Workspace widgets (market statistics, securities lookup with intraday sparklines, ticker cards, a TradingView advanced chart over all equities/indices/futures, and the hkexnews filings viewer) and the bundled app layout. They are mounted under /hkex/* whenever the extension is served by openbb-api; no separate app process is required.
