Schema: SpdrParentLimit (ID: 4090)

SpdrParentLimit records are supplied by clients (via SRSE) for use with parent orders having orderLimitType=Aux. This table can be updated either before or after a parent order begins working and will influence the limit(s) used when working child orders. Updates to this table do not constitute cancel/replace operations for the parent order.
