SGX: Cobalt and Lithium Contracts

September 26

SGX has announced the introduction of SGX FM Cobalt and Lithium Contracts with a launch date of September 26, 2022. The products are available for testing in UAT now. Please note the following two points for UAT testing: (1) TTW traders testing Cobalt and Lithium Contracts will see incorrect Profit and Loss calculations in the TTW Positions Widget. (2) The Product Names will not appear in TTW Widgets or in Product/Instrument downloads of other applications. These two issues will be corrected during the week of September 19 or earlier. These two issues are specific to UAT testing only and will never impact Production.

FIX: Logon Tag Validation

September 30

TT FIX has introduced a new feature that will enable FIX sessions in UAT and Production to be routed to a specific host in the environment rather than being randomly assigned a host by the HA Proxy load balancer during Logon. The new feature will give customers and TT greater flexibility in routing sessions for the purposes of testing, diagnosis, early access to new features or roll-back to older versions of the TT FIX servers.

When the new feature is enabled, HA Proxy performs tag validation on the FIX Logon (35=A) message to ensure that the FIX message is well formed. The Logon message may only contain standard tags for that FIX Version, or custom tags in the range 10,000 to 19,999. If the logon contains tags that are outside the permitted range for that version (for example, a FIX 4.2 logon containing FIX 4.4 tags 553 and 554), that logon will be rejected. 

The TT FIX Integration team has performed an analysis of current production Logon messages and is contacting customers directly to request removal of any non-standard tags from their FIX 4.2 or 4.4 logons. Customers that connect to dedicated FIX servers bypass the HA Proxy load balancer and are not impacted.

The new feature is currently enabled in UAT only. Production deployment will begin on September 30 and take 3 to 4 weeks to fully deploy to production. Customers must remove any non-standard FIX tags from their Logon messages prior to September 30. 

For questions regarding FIX Logon, please contact TT FIX Integration at For information on configuring the new feature in TT Setup, please contact TT Onboading at

ICE: Mandatory Requirement of Manual Order Indicator (“Tag 1028”)

From the exchange:

In March 2022, ICE Futures U.S. (“IFUS” or the “Exchange”) issued a notice detailing the mandatory inclusion of a Manual Order Indicator on order messages in FIX Tag 1028 effective October 3, 2022.

ASX: 3 Year Bond Futures Minimum Price Increment Changes

October 17

In response to current market conditions of the 3 Year Bond Futures contracts, ASX has announced plans to make a change to the minimum price increment to improve market quality and liquidity.

Starting from October 17, 2022, ASX will change the 3 Year Bond Futures minimum price increment from 0.005 to 0.002 during the non-roll period, which is from 17:10 on the 8th of the expiry month (or next business day if the 8th is not a business day) until 16:30 on expiry day.

At the time of the price increment change from 0.002 back to 0.005 (16:30 on expiry day), ASX will purge all working orders that do not conform to the standard 0.005 price increment. All such orders will be removed from the TT system via order expiration update.

TT has verified that the current Production Release version of the TT Platform correctly supports ASX’s improvement with no need for changes. Please note that TT has identified a rare situation in which TTW MD Trader failed to reflect the price increment change. This issue is under low-priority investigation, but TTW Users who encounter the problem can correct it immediately by right-clicking MD_Trader and selecting “Refresh Instrument Definition.”

October 30

On Sunday, October 30 (trade date Monday, October 31), to streamline the dissemination of CME FX market data offerings, CME FX futures and options instruments will be migrated onto distinct existing market segments and their MDP 3.0 market data channels consolidated on CME Globex as follows:

  • Migrate all CME FX futures and FX Link instruments to a single market segment (MDP 3.0: Tag 1300-MarketSegmentID=52) from the current two market segments.
  • Migrate all CME FX options instruments to a single existing market segment (MDP 3.0: Tag 1300-MarketSegmentID=88) from the current two market segments.
  • Consolidate the CME FX futures market data channels to a single market data channel (MDP 3.0: TAG ApplID-1180=314) from the current two market data channels
  • Consolidate the CME FX Options market data channels to a single market data channel (MDP 3.0: TAG ApplID-1180=321) from the current two market data channels

While the migration and consolidation will be handled by TT, customers must cancel any GTC/GTD orders on existing segments 52 and 88 before the close on Friday, October 28th. CME will not be cancelling these orders, and if remaining they will be visible but unmanaged through the TT platform. If customers do not cancel GTC/GTD orders by the close on Friday, October 28th, they will need to work with the exchange for further actions.

These changes will be available in the UAT environment on Monday, October 3rd.

Additional information

ICE: Mandatory Migration from LMA to IM-SMA

December 31

ICE has started the process of phasing out Locally Managed Accounts (LMAs) by introducing a new set-up feature, called Independently-Managed System Managed Account (IM SMA) in the ICE Clearing Admin tool which is designed to replace LMAs. The timeline for the migration has been set to year-end.

The new ICE IM SMA feature is available within the SMA functionality and is replacing the legacy LMA, which will be phased out completely by December 31, 2022. The new IM SMA feature offers Clearing Members more control over accounts than is available with LMA. 

With IM SMA set-up, it is mandatory to send in tags 439 (Clearing Firm) and 440 (Clearing Account) to the exchange. The customer could continue using tag 9207 (CustAccountRefID field) as an optional field to distinguish the customer business. ICE is targeting December 31, 2022, as the end date for LMA access. In line with this milestone, ICE will not support the creation of any new LMA access starting August 1, 2022.

The TT platform already supports the required tags for IM SMA as required by ICE. Below are the mappings between the required tags and the respective fields in the TT user setup.

  • Tag 439 – Clearing Firm ID
  • Tag 440 – Exchange Account

Customers are requested to get in touch with TT onboarding team in case any assistance is needed for setup.

Eurex: Next Generation ETD Contracts

February 6, 2023

Eurex is aiming to introduce a more flexible set-up of Exchange Traded Derivatives (ETD) products by implementing an enhanced contract identification concept in February 2023 allowing more than one expiration per month on product level (sub-monthly contracts).

New features, changes and improvements:

  • Integration of Weekly Expiring Instruments on Product Level
  • Volatility Strategies in Single Stock Options
  • Market-On-Close Futures T+X (Basis Trading in Equity Index Futures)

Weekly contracts will follow the new format of DDMMYYYY (current format: MMYYY), and will be listed under the same Product symbol as the Monthly contracts. 

Example: OEB1, OEB2, OEB4, OEB5 will be listed under the OESB Product Symbol, and will be sequentially integrated into the following month as they expire. 

Currently, the Weekly options are:





Current Monthly Option:

OESB Oct22

At the end of the integration process, the October contracts will be the following:

OESB Oct22-W1Fr

OESB Oct22-W2Fr

OESB Oct22

OESB Oct22-W4Fr

OESB Oct22-W5Fr

It is important to note that the Weekly Options will sequentially migrate after each weekly option expires.

For example, in the third week in October,  OEB1 and OEB2 have already migrated to their OESB November Week 1 and Week November 2 display names, while weeks 4 and 5 have not migrated yet.

Here is another example with a visual aid:

Market on Close T+X will be eligible for MSCI Futures. An example is the following:

On T, Client trades the calendar between the daily future (T+1) and the standard future. After the T+1 session, the index close of T+1 is published by MSCI. On T+2, the T+1 index close is entered as the Final Settlement Price for the daily future. At the end, the Client has paid basis + index close for the standard future. 

Eurex Next Generation ETD contracts are now available in UAT for customer testing. The following products are now available, please see the product symbols below and use those for testing purposes:

Active as of July 2022:

T+X MSCI Futures and Spreads (FMEA, FMWN)

Integration of sub-monthly options (NOA3, OGBL, AXA, BAY, CSGN, ROG, ODAX (including end of month contracts), OSMI)

Daily expiring single stock futures (AXAP, BAYP, NO3P, ROGP)

Activation Date in Simulation: September 23, 2022 (integration period until October 18, 2022):

Starting 23 September 2022, Eurex will gradually integrate all weekly expiring contracts OES1/OES2/OES4/OMSX into the standard option OESX. Please find below the detailed migration schedule:

Activation Date September 30, 2022:

Daily expiring contracts in MSCI Futures FMWO, FMJP, FMEF

Activation Date October 6, 2022:

Daily expiring contracts in single stock futures in ADSP, BMWP, UBSP

Please refer to the attached Eurex Simulation Calendar, as the 3-day rolling contracts will follow the Business Day rather than Calendar day.
