What this video covers

  • When the Don't Know (DK) procedure applies: only to member-to-member trades outside a registered clearing organization
  • The correct chronological trigger for starting a DK sequence (after comparison, never after missed delivery) and why sequence matters
  • The confirming member's role: sending the notice claims the trade, so the sender has not DK'd anything
  • How silence from the contra-member constitutes a DK under the alternative form
  • Why a DK issue and a delivery fail live at completely different stages of the trade lifecycle
  • The exact three-step path from confirmed trade to delivery fail, and why confirmation must precede any fail
  • How aged securities fails are a separate topic from DKs, require their own confirmation, and lead to the buy-ins and close-outs lesson
