Effective June 19, 2023, Cboe SEF will require Participants to provide an Order Entry Operator ID (OEOID) when registering an Authorized Trader with Cboe Member Services. OEOIDs should correspond to a unique Participant Authorized Trader. That is, each Authorized Trader should have a unique OEOID and an Authorized Trader may not use the OEOID of any other natural person or entity. Participants will also be required to submit an OEOID with all Order entry and quote messages no later than December 15, 2023.
FIX API
A new custom field OEOID will be introduced:
| TAG | Field Name | Requirement | Description |
|---|---|---|---|
| 5004 | OEOID | Y Effective December | Identifies the Order Entry Operator responsible for this message. Alphanumeric only. OEOID should correspond to a unique Participant Authorized Trader. |
OEOID will be required for the following messages:
Cboe SEF ECN
Cboe SEF Full Amount
Cboe SEF will not validate the content of the field and will not echo back the value in any outbound messages.
For each Price Feed session, a default OEOID (corresponding to an Authorized Trader registered with Cboe SEF) agreed upon with the Participant will be configured. Cboe SEF would associate all quote messages with such OEOID.
Alternatively, Participants can enhance their proprietary API to provide Cboe SEF with the OEOID value for quote messages.
If you have any questions regarding this Notice to Participants, please contact the Trade Desk at [email protected].
