Cboe Closing Cross (3C)

Close the day at your chosen price

Cboe Closing Cross (3C) is a new post close trading service designed to provide a simple, cost-effective way for market participants to execute their end of day trading activities. 3C gives market participants the opportunity to choose the price they wish to trade at after the continuous trading session has ended.

3C functions independently from the listing exchange and does not depend on their closing auction price. With 3C, participants enter orders, set their “at limit” price and the 3C formulates a volume maximising cross every 15 seconds throughout the 25-minute session.

Cost Effective, One-Stop Shop

  • With Cboe Europe’s pan-European coverage, 3C is a cost-effective, one-stop solution for customers looking to execute their post close trading activities across 18 European markets.

A Better Alternative

  • Avoid the complexity and cost of other end of day trading sessions
  • Easily navigate risk with no order lock-ins to allow cancellation at any point
  • Seamless implementation simply use 9303=BU FIX tag to turn a normal limit order into an “at limit” order during the 3C trading phase.
  • Technology you can trust when other auctions fail or get delayed
  • Larger order size encouraged with minimum quantity feature
  • Full pre-trade transparency in data feed and indicative crossing summaries
