The International Securities Exchange (ISE) announced today that its Depth of Market Feed for options is now available through PrecISE Trade™, its proprietary front-end trading application. ISE’s Depth of Market Feed is a real-time data feed that provides the aggregated volume of all quotes and orders available at each of the top five price levels for options that trade on ISE.
With ISE’s Depth of Market Feed, PrecISE users will now have market transparency for ISE’s options exchange beyond the Best Bid and Offer (BBO) to enhance their trading efficiency. The Depth of Market Feed will also enable PrecISE users to view the size of customer orders at all price levels. All PrecISE users will immediately have trial access to the Depth of Market Feed through their existing subscriptions.

Launched in October 2007, the Depth of Market feed is delivered using the FIX FAST protocol. In addition to being available through PrecISE Trade, the feed is currently distributed from a number of connectivity providers including BT Radianz via its Radianz Shared Market Infrastructure and by NYSE TransactTools Secure Financial Transaction Infrastructure (SFTI®) on a subscription basis.
