Critical System Updates

iLink Convenience Gateways Behavior Harmonization - January 6, 2019

To simplify the iLink session behavior, effective Sunday, January 6, 2019 (trade date Monday, January 7), all Convenience Gateway (CGW) iLink sessions will move to MSGW-style Session Connection and Resend Request. The following CGW features will as a result match the MSGW current state.

Please note that certification is required for all CGW customer systems via AutoCert+ by end of day Friday, January 4, 2019, for continued access to the production environment. Customer systems that trigger port closures due to resend requests or other issues will not be allowed to reopen ports and access the market until certification is complete.

iLink Convenience Gateways Behavior Harmonizations
Functionality	Current Behavior	New Behavior	Certification Required
Duplicate Session Connection Attempts	Accepted, then disconnected	Ignored	No
Resend behavior from CME Globex to Client System	No real-time messages are published until the customer’s resend request is satisfied	Real-time messages will be interleaved with resend responses CGW customers must be able to receive out-of-sequence during a resend response without triggering another resend request	Yes Please Note - A new CGW Resend Request certification test is currently available in Autocert+. Certification via AutoCert+ is mandatory for all iLink CGW customers.

These changes are currently available in New Release for customer testing.

Drop Copy is not impacted by this change.

Price Precision Extension - January 13, 2019

CME Group is implementing end-to-end technology changes to support increased price granularity. Currently, CME Group systems support a maximum of 7 decimals. With this initiative, products with up to 9 decimals may be listed and traded. On Sunday, January 13, 2019 (trade date Monday, January 14), pending regulatory approval, the 2-Year Treasury Note futures, all 2-Year Treasury Future Spreads (including Calendar Spreads, Tail Spreads and Inter-Commodity Spreads with a 2-Year Treasury Future) along with the futures portion of covered options UDS, will move from 7 decimals to 8 to support trading at 1/8 of 1/32.

A production test instrument for the 2-Year Treasury Note futures is currently available on CME Globex to give customers the ability to confirm system readiness for the introduction of 8-digit decimal price precision. Clients systems that are not prepared to handle 8 decimal precision must ensure their systems have the ability to ignore market data and iLink/Drop Copy execution reports on the new test instrument.

Customers are encouraged to move to support 9 decimals now; but there are no plans to list a product that uses the 9th decimal at this time.

Customer certification is required for MDP 3.0 and Streamlined SBE. The new Market Data templates are currently available in New Release, AutoCert+, and in production.

The Client Impact Assessment includes additional information on the following:

• CME Globex iLink
• CME Globex MDP3 and Mandatory Certification
• Streamlined MDP and Mandatory Certification
• ITC
• CME Globex Drop Copy
• Referential Data
• Production Globex Test Instrument

Month SOFR Futures Exchange-Defined Spread   - Q1 2019

In Q1 2019, 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 in Q1 2019.
