Top of PHLX Options - TOPO

Is a speed advantage important to you when trading options? Take Top of PHLX Options and be faster than your competition!

Overview

Top of PHLX Options (TOPO) is designed to provide Nasdaq PHLX (PHLX) Best Bid and Offer and last sale information directly to PHLX market participant firms - the same information PHLX provides to the Options Price Reporting Authority (OPRA) for inclusion in the consolidated market feed. However, by subscribing to TOPO directly from PHLX, market participants can eliminate any extra transmission and processing latencies and be able to process the information faster, giving them an additional tool to compete with those taking the data from OPRA.

Firms also interested in simple and complex order data should refer to the TOPO Plus Orders data product.
