Real-time Request for Quote (RFQ) and quote notifications. Requires authentication.
Requirements:
- Authentication required
- Market specification ignored
- RFQ events (RFQCreated, RFQDeleted) always sent
- Quote events (QuoteCreated, QuoteAccepted, QuoteExecuted) are only sent if you created the quote OR you created the RFQ
Use case: Tracking RFQs you create and quotes on your RFQs, or quotes you create on others’ RFQs. Use QuoteExecuted to correlate fill messages with quotes via client_order_id.
