Rejection of NewOrderCross Messages with Traders Containing more than Five Characters	FIX EntryPoint Gateway	No	Nov/2024	2nd quarter/2025	2nd quarter/2025	NewOrderCross (35=s) FIX message types will be rejected when the values given in PartyRoles EnteringTrader (452=7) and ExecutionTrader (452=36) have more than five characters.	This change takes into account the non-existence of operators registered on the platform containing more than 5 characters, thus limiting the size of the information present in this field to possibly valid values.
