Advanced technology. Unmatched speed.
OUCH provides customers with a fast and highly efficient way to connect to NASDAQ and NASDAQ OMX BX. This protocol allows subscribers to quickly enter orders into and receive executions. OUCH was developed with simplicity in mind — subscribers and their software developers can integrate NASDAQ into their proprietary trading systems or build custom front-ends to NASDAQ systems.
OUCH accepts limit orders from system subscribers, and if there is a matching order, they will execute. Non-matching orders are added to the Limit Order Book, a database of available limit orders, where they are matched in price-time priority. OUCH only provides a method for subscribers to send orders and receive status updates on those orders.
