Delta1 is the exchange's proprietary electronic trading platform. The trading platform facilitates competitive matching of bids and offers through a central limit order book, as well as reporting of bilaterally negotiated block, spread, and Exchange of Future for Physical (EFP) transactions. All transactions matched or reported through Delta1 are centrally cleared at the Options Clearing Corporation (OCC).

The trading platform's basic function:

  • Electronic central limit order book for price-time priority matching of bids and offers
  • Dedicated trade reporting engine for clearing off-exchange bilaterally negotiated security future block, spread, and EFP transactions
