summary: 'IntelligentCross publishes a UAT (user acceptance test) environment for its
  IQX market data feed alongside production, with its own multicast groups, ports and
  feed identifiers, all documented in the public Market Data Feed Specification v1.11.
  It also publishes downloadable sample data - a full-day PCAP capture of the feed and
  the daily pipe-delimited symbol mapping file - so a consumer can build and validate
  a decoder before requesting connectivity. There is no public self-service sandbox
  for order entry: FIX access requires a subscriber agreement and a cross-connect.'

test_data:
- name: Sample IQX PCAP capture
  description: Full-day capture of the IQX feed (mdA), gzipped PCAP, published for decoder
    development and validation.

- name: Daily symbol mapping file
  description: Static pipe-delimited Symbol ID to Symbol mapping file, published daily.
    Symbol ID to Symbol mapping may change from day to day, so consumers using Symbol
    ID must refresh this file daily.
  url: https://s3.amazonaws.com/iqx.imperativex.com/Symbol-Mapping.txt
  format: pipe-delimited text
example_values:
  note: The Market Data Feed Specification Appendix A works its examples with the fictitious
    stock symbol ACME and the imagined IntelligentCross Symbol ID 31999. These are illustrative
    values from the provider's own documentation, not live identifiers.
  example_symbol: ACME
  example_symbol_id: 31999
order_entry_sandbox:
  available: false
  note: There is no public self-service test environment for order entry. FIX access
    requires a subscriber agreement (registered US broker-dealers only) and NY4 connectivity;
    the FIX specification and onboarding materials are requested from ops@intelligentcross.com.
