Schema: ParentOrderGateway (ID: 5180)

Records inserted, updated, or replaced into the ParentOrderGateway table are validated and then converted to SpdrParentOrder records and forwarded to the appropriate execution engine for futher processing. Parent orders can be inserted as either active/ready or in a wait start mode that requires subsequent release.

See the SpiderRock Execution Engine concept guide for more details.
