How do you clear orderbook before new session for MBO

I am working on TREP FH as provider for Market By order domain. My question is how does the TREP FH notify downstream clients to clear the orderbook before start of new trading day? Now I know we can use status message with Clear Cache flag, but wouldn't that also remove the summary data (reference data) with the associated RIC together with the orderbook? And should the TREP FH use RSSL_STREAM_CLOSED_RECOVER with dataState as suspect to let ADH query for the RICs later?

@vishal.anand

Thank you for reaching out to us.

It will not send RSSL_STREAM_CLOSED_RECOVER to clear the order book.

It should use CLEAR_CACHE.
