Deribit has moved publication of open-interest figures for all futures and options instruments to an eight-hour delay.
The exchange says the lag applies to all futures and options instruments. Deribit defines open interest as the number of outstanding contracts; a figure alone cannot show activity that changes those positions during the eight-hour gap. The exchange’s educational material says max-pain calculations use open-interest figures, so those calculations will also rely on delayed data.
Deribit says execution and margin and equity updates remain real time under the publication policy; that statement does not establish uninterrupted client access during maintenance. Its maintenance notice said scheduled work on Tuesday, Nov. 10, would prevent client systems from communicating with the exchange. The window was due to start at 4 a.m. ET (09:00 UTC) and was expected to last about 45 minutes.
Deribit also offers delayed publication for qualifying large Block Request-for-Quote (RFQ) trades when enabled on request. The exchange says the option is intended to reduce front-running as later portions of a large order are completed, and cites MiFID II large-in-scale rules as a similar approach. That option gives large-order traders more time to complete an order before qualifying RFQ trades are disclosed publicly.
