When: - there is partial execution in the maturity that is giving rise to the synthetic order and there is not enough quantity to maintain the synthetic order; - there is full execution in maturity that is giving rise to synthetic order; - there is a change in the best price in maturity that is giving rise to the synthetic order, because of the trade result (for example: reopening of the apparent lot and triggering of a Stop order); - if an auction occurs in any of the maturities that give rise to the synthetic order, this synthetic order will be canceled. However, after the auction ends, the synthetic order will be reestablished if new orders are submitted with the best price in the maturities that give rise to the implied.

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.
