If you already have a SFTI or a third-party extranet line and have certified your FIX/Binary application, you can request creation, modification or removal of Production Sessions by contacting our Production Support Group at the email link or phone number below.

Once a trade has been executed, trade details are transmitted to the Depository Trust and Clearing Corporation (DTCC®) / National Securities Clearing Corporation (NSCC®) for clearance and settlement via their Universal Trade Capture (UTC) processing stream. All trading transactions are transmitted to DTCC / NSCC electronically in real time matching the details of the trades from both the buyer and the seller into one deal record. These transactions are considered "locked in" executions.

Clearing firms must become NYSE Chicago Equity Trading Permit (ETP) holders to obtain direct access to NYSE Chicago and clear trades on behalf of exchange participants and be setup to participate on the NYSE Chicago RIO. Firms that are not self-clearing must have their NYSE Chicago clearing firm provide a Clearing Letter of Consent to the CRS / Membership acknowledging and accepting the financial responsibility for all of their correspondent’s transactions. To direct orders to NYSE Chicago, clearing firms must complete additional membership agreements.
