Becoming a BOX Participant

All brokers-dealers seeking trading privileges with BOX must complete the following BOX Participant application documents:

• BOX Participant Application
• BOX Participant Agreement

Information about the membership application process can be found in the BOX Applications and Form Instructions document.

Each BOX Participant must ensure that a Clearing Guarantee document is completed by the clearing firm that will act as Clearing Agent at the Options Clearing Corporation (OCC) for all trade executions on BOX. This document must be completed and submitted by the BOX Participant prior to the debut of trading by the Participant. Two forms, listed below, are available depending on whether the BOX Participant is a market maker or a non-market maker; use the appropriate form.

• OCC Clearing Guarantee Form for Market Maker
• OCC Clearing Guarantee Form for Non-Market Maker
