  Request throttling of the HKEX FINI API Gateway, from the public FINI API
  User Guide. Throttles refresh every 60 seconds; each company registered on
  the HKEX Access Management Portal has a 480-requests-per-60-seconds
  threshold, and a global per-endpoint throttle sized to expected peak traffic
  means HKEX recommends API machines stay at or under 60 requests per 60
  seconds. Throttled requests receive HTTP 429.
