Getting Started

The AutoCert+ tool is an automated testing tool for validating application functionality. It provides an easy-to-use web interface for walking through CME Group certification scenarios.

To facilitate the process of connecting a customer application to CME Globex, CME Group provides a dedicated certification environment to allow customers to test their systems before they complete certification.

The following apply to each iLink test case:

  • The book is clear at the beginning of each test.
  • AutoCert+ selects dummy instruments based on the product type selected from the Select a Contract field drop-down list.
  • After the instrument is selected, the instrument is locked until the test is completed.
  • If you submit an incorrect response to any question in a test case, you must repeat the test case from the beginning.
  • For partial or complete fills, assume CME Group creates the appropriate orders in the book.
  • For all inbound messages, tag 60-TransactTime must include milliseconds in the following format: HH:MM:SS.sss, such as 10:00:29.714.
  • AutoCert+ validates tag 167-SecurityType on inbound messages where it is required.
  • AutoCert+ requires that tag 1-Account be included in all Order Cancel Request Tag 35-MsgType=F messages.
