Re: Sequence Channel Reset
Date: May 30, 2018

OneChicago, LLC (“OneChicago”) is issuing this Notice to Members (“NTM”) 2018-23 as a courtesy to inform market participants that due to a technical issue, OneChicago has reset sequence numbers on all A and B feed channels via the OneChicago Ticker Plant (OCTP).

Consistent with OCTP protocol the receipt of a Good Morning serves to indicate a channel sequence reset.
