11 - ClOrdID
string
required
Unique identifier of the order. The ID can be one of the following formats:
  • Ever-Increasing Positive Numbers: Ever-increasing positive numbers, such as microsecond timestamps, to ensure the uniqueness and sequential nature of the identifiers. Example: Using the current microsecond timestamp as the ClOrdID, such as 1623448294234000 (Max 18 characters)
  • Timestamp-First v4 UUIDs: A timestamp-first v4 UUID might look like 1b4e28ba-2fa1-11d2-883f-0016d3cca427, where the initial part (1b4e28ba-2fa1) of the UUID represents the timestamp. The timestamp granularity to generate the first part needs to be 10 microseconds maximum such as 162344829423400.
