summary: 'IntelligentCross versions its interfaces as dated specification documents rather than
  as URI or header API versions. The current market-data contract is Market Data Feed Specification
  v1.11 (2020-07-30) with a companion Rerequest Specification v1.08; the order-entry contract is
  FIX 4.2 and its specification is subscriber-gated. No status page, SLA page or written deprecation
  policy was found on any imperativex.com host. Operational continuity is published instead as an
  annual Business Continuity Plan summary.'

  docs: https://www.imperativex.com/market-data
  note: 'The FIX version supported is stated as "currently supports FIX 4.2" - the venue reserves
    the ability to change it and does not publish a version-support matrix.'
