OneChicago – Getting Started

Thank you for interest in trading OneChicago markets.  OneChicago operates the only U.S. based securities futures marketplace.  Our primary match engine is the CBOEdirect platform, a state of the art high throughput matching engine.  OneChicago also provides OCX.delta1, an electronic marketplace for transacting and reporting block, block rolls and Exchange Future for Physicals (“EFP”) in OneChicago products.

Firms must be Option Clearing Corporation (“OCC”) Members approved for single stock futures.  Non-member firms and individuals should arrange access through these firms.

Getting Started
Firms interested in trading OneChicago need to complete two parallel paths, one covering registration and authorization, the other covering technology access.

Registration and Authorization
