The collectionID is composed of two parts using ’=’12 as a separator. The first part is a free text field with an indicative name for the type of a collection when the second part is an identifier for individual collections which must be unique on each trading day. Examples of the collectionID field value are ’basket=BSK123’, ’wave=20181011-123’ and ’tmc=TMC_HSI/123’. In case an order is part of multiple collections (i.e. an order may appear in multiple groupings), the In-Scope Broker should use ’|’ as delimiter to concatenate them, e.g., ’basket=BSK123|tmc=TMC_HSI/123’.
