MT524 Usage Rules

This message must not be used to move securities out of or into a safekeeping account. It instructs only movements that affect the status/availability of the security, that is, movements from one sub-balance to another or intra-position transfers, within a safekeeping account.
To confirm an intra-position instruction, the account servicer must use the MT 508 Intra-Position Advice.
