Consolidated iLink Fill Messages - February 3

Starting Sunday, February 3 (trade date Monday, February 4), CME Group will launch consolidated iLink fill messages on CME Globex to reduce the number of iLink Execution Report - Fill messages.

The key client system impacts of consolidated iLink fill messages include:

• iLink Fill Behavior Change
• CME Group will not implement tag 9700-NumOrdersInMatchStep
• New repeating group for Fill Reason

New Functionality

3-Month SOFR Futures Exchange-Defined Spread   - March 10

Effective Sunday, March 10 (trade date Monday, March 11), a new exchange-defined Averaged Price Bundle futures spread (FIX tag 762-SecuritySubType=AB) for the 3 Month SOFR futures will launch on CME Globex. The AB spread type will allow customers to trade the 3-Month SOFR quarterly futures contracts with leg price sensitivity to the underlying market.

Averaged Price Bundle Futures Spread – 3 Month SOFR Futures
Product Name	MDP 3.0: tag 6937-Asset	iLink: tag 55-Symbol MDP 3.0: tag 1151 - Security Group	762-SecuritySubType
3-Month SOFR Futures	SR3	SS	AB

This strategy is available as a futures Exchange-Defined Spread only.

Averaged Price Bundle spread has:

• One product
• Minimum of four legs
• Maximum of 40 legs
• Expiration of all the legs must be consecutive quarterly outright futures
• Quantity/side ratio +1:+1:+1:+1:…+1

Example:

• Instrument Symbol = SR3: AB
• Leg1 fair market price = xxxx
• Leg2 fair market price = xxxx
• Leg3 fair market price = xxxx
• Leg4 fair market price = xxxx

Please Note:The fair market price can be either the most recent available prices from outright markets; trade, best bid/best offer, or Indicative Opening Price.

Pricing:

• The Averaged Price Bundle spread trade price is = (Leg1+Leg2+…LegN)/total number of legs
• Leg price assignment:
  • Any fair market eligible .25 tick legs are rounded up to .50 tick
  • The difference between the total spread trade price (multiplying the trade price by the number of legs) and the sum of the spread fair market price is calculated:
    • [(Trade price * number of legs) – (Sum of the legs’ fair market price)]
  • The average differential from step 2 is applied to each leg’s fair market price
    • Legs may be adjusted to equal spread trade price
• Any adjustment of the outright leg prices due to remainder will be assigned according to the Averaged Price Bundle leg pricing assignment rules.  The remainder will be applied in .50 increments starting with most deferred leg.

Pricing Example – Equal Distribution:

Averaged Price Bundle trades at 9705.0

• Leg1 fair market price = 9706.5
• Leg2 fair market price = 9705.5
• Leg3 fair market price = 9703.5
• Leg4 fair market price = 9702.5
• Total spread trade price – Sum of fair market price
  • 38820.0000 – 38818.0000 = 2
• Apply average differential to each leg:
  • Leg1 = 9707.0
  • Leg2 = 9706.0
  • Leg3 = 9704.0
  • Leg4 = 9703.0

Pricing Example – Unequal Distribution:

Averaged Price Bundle trades at 9700.0

• Leg1 fair market price = 9706.0
• Leg2 fair market price = 9705.5
• Leg3 fair market price = 9703.5
• Leg4 fair market price = 9702.5
• Total spread trade price – Sum of fair market price
  • 38800.0 – 38817.5 = -17.5
• Averaged Price Bundle remainder leg pricing assignment rules applied
• Apply average differential to each leg
• Apply remainder starting with most deferred leg
• The legs are adjusted as follows:
  • Leg1 = 9702.0
  • Leg2 = 9701.0
  • Leg3 = 9699.0
  • Leg4 = 9698.0

These contracts are listed with, and subject to, the rules and regulations of CME.

The spread will be available for customer testing in New Release on Monday, February 4.

CME FX Option Changes  - June 9

Effective with the listing of the September 2019 quarterly options, these CME FX options will reflect the following changes:

• Expiration time will be 9:00 am Central Time (CT). Currently, these options expire at 2:00 pm CT.
• Exercise will use the 9:00 am CT fixing price instead of the 2:00 pm fixing price.

These changes will be in effect for all option instruments that expire after Sunday, June 9, 2019. Currently listed instruments, and any instruments that expire before June 9, 2019, will continue to use the 2:00 pm expiration and 2:00 pm fixing price for exercise.

Additional information on these changes including a two minute overview video can be found at cmegroup.com/10am.

The instrument last trade date and time can be found by leveraging FIX tags 865=7 (Last eligible trade date) and 1145-EventTime in the Security Definition (tag 35-MsgType=d) message.

The Fixing Price data blocks are sent in the MDP 3.0 Market Data Incremental Refresh (tag 35-MsgType=X) with the following attributes:

• Tag 279- MDUpdateAction=0 (New)
• Tag 269-MDEntryType=W (Fixing Price)
• Tag 270-MDEntryPX = Price of the MD Entry (This value will contain the fixing price).
• Tag 5796-Trading Reference will display the date for which the fixing price was calculated.

This change is currently available for customer testing in New Release.

These contracts are listed with, and subject to, the rules and regulations of CME.
