Subject | Allocate And Claim System (ACS) -- Update - Enhancement To API Message Function.
Effective Date | 12/20/02
Notice Number | CMO#0325
Effective with the launch of the new ACS system on January 10, 2003, we will be implementing a new give-up API message type designation of �GUC� to accommodate sub-allocations and third-party give-ups. The examples below help to illustrate when the new message will be created: Marking an accepted give-up for sub-allocation When the carry firm marks an accepted give-up trade for sub-allocation or to be given up to another firm, the following message types are created: � GUC: sent to carrying firm, confirming the intent to sub-allocate � GSA: sent to carrying firm, acknowledging creation of the order GUS-API can now receive a GA message, allowing the carry firm (now executing firm) to allocate. Sub-allocating accepted give-ups and specifying sub-allocation accounts When the carry firm (now executing firm) accepts a give-up and allocates part or all of the accepted give-up to a different account within the same firm, the following messages are created: � GUC: sent to carrying firm (now executing firm), confirming the intent to sub-allocate � GSA: sent to carrying firm (now executing firm), acknowledging creation of the order � GAC: sent to carrying firm (now executing firm), informing of allocation � GAA: sent to carrying firm (now executing firm), shows new allocation account GUS-API can now receive a GC message to accept a sub-allocated give-up. Message types created when using the auto-accept rule When the Carry firm (now executing firm) allocates part or all of accepted give-up to different accounts, and auto-accept rules are in place, the following messages are created. � GUC: sent to carrying firm (now executing firm), confirming the intent to sub-allocate � GSA: sent to carrying firm (now executing firm), acknowledging creation of the order � GAC: sent to carrying firm (now executing firm), informing of the allocation � GAA: sent to carrying firm (now executing firm), showing the new allocation account � GCA: sent to carrying firm (now executing firm), showing the allocation acceptance � GCC: sent to carrying firm (now executing firm), showing the allocation acceptance Marking an accepted give-up for third-party Give-up When the carry firm (now executing firm) accepts a give-up, and allocates part or all of the accepted give-up to a different firm and account, the following message types are created: � GUC: sent to carrying firm (now executing firm), confirming the intent to sub-allocate � GSA: sent to carrying firm (now executing firm), acknowledging creation of the order � GAC: sent to carrying firm (now executing firm), informing of allocation � GAA: sent to new carrying firm (third-party firm), shows new allocation firm and account GUS-API can now receive a GC message to accept sub-allocated give-up. Message types created when using the auto-accept rule When carry firm (now executing firm) allocates part or all of an accepted give-up to a different firm and account, and auto-accept rule in place, the following messages are created: � GUC: sent to carrying firm (now executing firm), confirming the intent to sub-allocate � GSA: sent to carrying firm (now executing firm), acknowledging creation of the order � GAC: sent to carrying firm (now executing firm), informing of allocation � GAA: sent to new carrying firm (third-party firm), shows new allocation firm and account � GCA: sent to carrying firm (now executing firm), shows allocation acceptance � GCC: sent to new carrying firm (third-party firm), shows new allocation firm and account To view a flow chart of the above examples, click on the following link: ACS Sub-allocation/Third-party Give-up Message Function.
