Cboe Options Exchange (C1) has issued a notice about its plans to decommission the PULSe Trader Workstation platform with effect from January 4, 2021.

Upon the effective date, users will no longer be able to log into the PULSe Trader Workstation application. They will also not be able to route order into PULSe or connect to any PULSe Drop Copy session.

C1 encourages users of the system to download their historical data before the effective date. Firms that utilize PULSe must cancel any open GTC orders entered via PULSe Trader Workstation prior to the close of business on December 31, 2020. Any remaining GTC orders entered via PULSe will be cancelled by the Operations Support Center at the close of business on December 31, 2020.

Firms may cancel PULSe related FIX ports via the customer portal at their discretion. After the close of business on January 29, 2021, C1 will cancel any remaining PULSe FIX ports on behalf of the firms.

Questions about the decommissioning of the PULSe Trader Workstation can be directed to the CBOE Operations Support Center at osc@cboe.com.
