This topic includes release notes about enhancements and updates to CME Optimizer Software versions.  

...

1.2. Enhancements

1.2.1.     PLN and MXN

CME will support MXN Overnight TIIE Funding Rate (F-TIIE) and PLN Warsaw Interest Rate Overnight (WIRON) swap clearing in the New Release environment on Wednesday, November 01, 2023 - please see the advisory here for more details. The Production support date is early 2024, please see CME's production advisories for more details. The New

Optimizer version 19 supports the curve data necessary for trading these new contracts. Users who do not trade these contracts are also required to support Optimizer version 19.

1.3. Fixes

1.3.1.     Treasury Rules-based Offset Engine (CME/FICC Cross Margin Program) Logic

...

1.5. Testing Considerations

As with all Optimizer test periods, it is recommended to test using a combination of input files:

...

This section illustrates changes to specific sections of the Optimizer’s configuration.json file to support treasury and SOFR option exclusions. Please see

See also: configuration.json file specifications here.

Option Lifecycle Exclusions

...

• The "cme_optimizer_marketdata . . ." file from the new release (NR) test environment.
• A positions.csv file generated in the test environment (unless SOFR and Treasury options are already in your production file, in which case, use production).
• All other input files from the production environment.

1.6. Out of Scope

 Treasury and SOFR options not in 1.2.1 above, including:

...

• Optimizer version 17 adds validation logic for invalid dates in the position.csv input file TradeDate field. Prior Optimizer versions defaulted transfer output to an un-tradable 1/1/0001 date when an improper TradeDate format was supplied. The TradeDate field is now expected to be in date format: yyyymmdd, mm/dd/yyyy, or m/d/yyyy. Optimizer version 17 produces an error at the portfolio level if the TradeDate field is not in these formats. The new expected error is:

  Invalid trade date format detected: '<<invalid format>>'. Expected yyyyMMdd or MM/dd/yyyy or M/d/yyyy

...

{
  "Enabled": true,
  "Name": "First Position Date - Treasury Roll",
  "BeginEventType": 17,
  "DaysBefore": 0,
  "EndEventType": 7,
  "DaysAfter": 0,
  "Type": "FUT",
  "Exchange": "CBT",
  "Codes": [ "17", "21", "25", "26", "TN", "UBE" ]
  },

• For MAC swap futures products:
  • Changes the BeginEventType exclusion attribute to be last trade date (enum = 7) and the EndEventType to be last delivery date (enum=14).
  • This was previously beginning at First Intent Date, which is about a week prior to delivery for these products.

  • Example updated config:

{
  "Enabled": true,
  "Name": "Last Intent Date - MAC DSF",
  "BeginEventType": 7,
  "DaysBefore": 0,
  "EndEventType": 14,
  "DaysAfter": 0,
  "Type": "FUT",
  "Exchange": "CBT",
  "Codes": [ "F1U", "B1U", "T1U", "N1U" ]
  },

• For Eurodollar options:
  • Changes the DaysBefore exclusion attribute to be 1 day.
  • This was previously 0 days before LTD which was identified as too close to E&A.
  • Example updated config:

{
  "Enabled": true,
  "Name": "Last Trade Date - ED Option Expiration",
  "BeginEventType": 7,
  "DaysBefore": 1,
  "EndEventType": 999,
  "DaysAfter": 0,
  "Type": "OOF",
  "Exchange": "CME",
  "Codes": [ "ED", "E0", "E2", "E3", "E4", "E5" ]
  }

...

• Optimizer v15.1 adds a new configuration property to control net option value capping/SPAN flooring in the Optimizer solution decision. 
  • Property Name: FloorSpanForFinalMarginCheck
  • Type: Boolean
  • Default Value: True
  • A value of "true" means that Optimizer caps NOV.

A value of "false" means that Optimizer does not cap NOV (same behavior as prior builds)

"FloorSpanForFinalMarginCheck": true

• • Background: 
    • Optimizer iterates through multiple solution states to find the best account savings. At the end of the Optimizer software workflow, it reviews possible solutions and selects one based on the lowest margin.
    • Net Option Value can act as a credit against computed market risk, and can lead to a SPAN Margin less than 0.
    • During margin settlement, total available net option value for a given portfolio is capped at the total Risk Maintenance Requirement using this formula:
      • If Risk Maintenance Requirement (RRM) is > or = total Net Option Value, then Total Requirement = RRM – NOV
      • If Risk Maintenance Requirement (RRM) < total Net Option Value, then Total Requirement = 0 due to NOV capping
      • For example, if an account’s computed risk factors are:
        • RRM = $1,000,000
        • NOV = $1,200,000
        • Then total requirement = $0, ANOV was capped to $1,000,000
  • Optimizer v15.1 allows users to specify whether the Optimizer should cap the net option value similar to the above when it makes its solution state decision.
    • For a given account, example 1: "FloorSpanForFinalMarginCheck": true
      
      • Optimized solution 1: IRS margin: 5,000,000; SPAN margin: 0 (capped); Total margin: 5,000,000
      • Optimized solution 2: IRS margin: 0; SPAN margin: 0 (capped); Total margin: 0
      • Optimizer chooses solution 2 with capping logic on
    • For the same account example 2: "FloorSpanForFinalMarginCheck": false
      
      • Optimized solution 1: IRS margin: 5,000,000; SPAN margin: -15,000,000 (uncapped); Total margin: -10,000,000
      • Optimized solution 2: IRS margin: 0; SPAN margin: -9,000,000 (uncapped); total margin: -9,000,000
      • Optimizer chooses solution 1 with capping logic off
      • Prior versions of Optimizer also choose this solution

Optimizer Version 15.0 Release Notes

...

This version of Optimizer support listed options in portfolio margining.

1. Updates to System Requirement (see User Guide)

2. Updates to Optimizer input files

   • Input File Contents/Number of Required Files
     • Optimizer version 15 requires 9 input files to run
       • All inputs will be required
     • Updated input file set is larger in size than prior versions of Optimizer
       • Version 15 input file set is ~ 700 MB in size, including one compressed file containing both existing and new input (details in grid below)
         • Uncompressed size is ~2.2 GB
       • Optimizer software will decompress the new zip automatically - not user intervention will be required.
       • Optimizer v14 previously required 13 files to run with a much smaller file size footprint
       • Firms with good network connectivity (dedicated circuits, 10 MB/s or higher) should expect reasonable (observed ~1 minute) transfer duration from FTP whereas firms connecting via internet should consider direct connectivity
   • There are no impacts to the firm-produced Positions.csv input file
     • Firms should continue to include options in the positions.csv file as normal. Firms not included options in the input file should add options.
   • Input File Publishing Timeline
     • New Optimizer input zip file will be published by 6 pm CT. The file latency is driven by increased computation load when CME Clearing produces options market data.
     • Timeline details for both ITD and EOD files is in the grid below.

Optimizer 15 Input File Impacts (all times CT)

...

***All test region (NR) file names are the same but include “.nr” at the end.

  3. Updates to Optimizer

...

Output Files 

• Optimizer will produce options transfer records in both Optimizer transfer output file formats (.csv and .txt)
• Options will be transferred at 0 price to mitigate movement of premium for Optimizer’s post-trade allocations.
• Output impact detail:
  • csvTransfersyyyymmdd_[run number].csv
    • File describes Optimizer transfer records in csv format
    • File will be updated to include options transferred at 0 price.
    • Similar to futures transfer records, options transfer records can generate with TransferOrigin = Optimizer, Netting, or Exclusion
    • Please note there are no new fields in the report
    • Sample:
  • fixmlTransfersyyyymmdd_[run number].txt
    • File describes Optimizer transfer records in fixml format. Firms typically use this file to transmit transfer records to CME via standard message queue channels.
    • File will be updated to include options transferred at 0 price.
    • Sample updated transfer record with highlighted additional fields for options:

...

Optimizer version 15 re-imagines the Optimizer’s existing exclusion configurations. Please note technical details about the new configurations can be found in the Optimizer User Guide.

Optimizer’s standard exclusion logic will be updated to include:

• Exclusions by performance bond account (PBAccount / margin account):
  • When Enabled = true, Optimizer users can specify an account identifier or a string of identifiers as well as a product type (i.e. options) from the positions.csv which Optimizer will exclude from Optimization.
  • To be used when a specific account owner would like to limit Optimization, for instance to prevent options from Optimizing. Users can simply remove an account from the positions.csv input file if no Optimization should occur.
  • The default is Enabled = false
  • See more in Optimizer User Guide

• Exclusions by product exchange:
  • When Enabled = true, Users can specify a product exchange (CME, CBT, etc.) or a string of product exchanges and Optimizer will exclude all line items in the positions.csv file which contain products found in that product exchange from Optimization.
  • The default is Enabled = false
  • See more in Optimizer User Guide

• Exclusions by product type alone or product type and product code:
  • When Enabled = true, Users can specify a product type (FUT, OOF, etc.) or a string of product types and Optimizer will exclude all line items in the positions.csv file with that product type from Optimization.
  • Users can specify a product type and a product code (41, TN, etc.) or a string of product codes and Optimizer will exclude all line items in the positions.csv file with that product type and product code from Optimization.
  • The default is Enabled = true and excluded products = OOF
    • Note: options in portfolio margining is pending regulatory approval, hence options will be disabled by this flag by default. 
  • See more in Optimizer User Guide

• Exclusions by trade event:
  • When Enabled = true, users can specify a trade lifecycle event (First Intent Date, Option Expiration date, etc.) and a window of days prior to that trade lifecycle event to establish an exclusion window for a product or string of products and Optimizer will exclude all products inside the exclusion window specified for that product.
  • The default is Enabled = true
  • See more in Optimizer User Guide

In addition to the standard exclusion logic above, Optimizer version 15 supports exclusion of options undergoing early exercise and assignment. Please note technical details about this configuration can be found in the Optimizer User Guide.

•  Non-standard exclusion logic: early exercise

  • When Enabled = true, Optimizer will exclude any options strikes which experienced an early exercise based on the clearing POS699C file (option exception summary report)
  • POS699C is included in the new cme_optimizer_marketdata zip file
  • Exclusion impacts short and long options positions and for excluded strikes, including those which are not assigned in the random assignment process
  • CME expects clearing firms to use this exclusion logic for the day 1 go live only. This exclusion logic should be turned off when firms are ready to go live with performing exercise and assignment in OTC accounts.
  • Firms not using this flag should make sure to be familiar with the other standard exclusion flags, described previously in this document.
  • The default is Enabled = true (v15 only)
