OUCH To Trade Options (OTTO)

Overview

OTTO provides customers with a fast and highly efficient way to connect to NASDAQ for trading options.

This protocol allows subscribers to efficiently enter options orders into and receive executions from NASDAQ. OTTO, like 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.

OTTO accepts limit orders from system subscribers, and if there is a matching order, the orders 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. OTTO only provides a method for subscribers to send orders and receive status updates on those orders.

Technical Specifications can be accessed on the Options Specifications page.
