Orders

We now support "Soft Limit" pre-trade risk thresholds that can be set locally by users in TTW Order Profiles. These limits provide notifications when certain risk levels are approached, but they do not automatically prevent trades. The ability to set these by administrators in Setup will be released in the near future. See our documentation for more details.

As part of the BIST's 3.12 release, BIST has made changes to the format of one of the reference data messages - BasicDataTradable (BDt). TT has released changes in it's software to handle these changes. There is no direct impact to any customers due to this change, and this change is expected to be transparent to the customers. Customers are still encouraged to perform testing in TT UAT, to avoid any adverse impact in Production.

Improvements

General

Previously, we implemented the “autoroll” feature to help maintain workspaces with minimal manual intervention and avoid manual addition and removal of instruments as they expire. However, this feature only covered outright futures instruments. We have now extended autoroll to cover exchange-listed spread instruments that are composed of monthly legs. With autoroll applied, when a spread leg expires, the spread instrument is automatically updated and replaced with the next available spread that maintains the monthly spread leg relationships. Note, this feature does not support exchange-listed strategies and spreads composed of non-monthly expirations.

Order Entry

When creating a manual fill on a care order for instruments that normally display as fractional formats (e.g., ZB as 115’08), you can now enable the ‘Price off tick’ checkbox to switch the price input control to accept decimal prices (such as 115.12345678) and create the fill with up to eight (8) digits of decimal precision.

FIX Services

FIX Market Data Request (V) and Snapshot (W) messages may now include tag 1, Account, for use in subscribing to different price streams on supported markets.
The TT account specified in tag 1 can only have a single stream configured, but a user may have multiple accounts configured each with a connection to an FX market that supports price streams. This will allow users to see/use different books for the same instrument.

The below features are not yet supported on this market, and will be added in a subsequent release - - Implied Prices - Settle Prices are not received everyday, and this is being worked out with the exchange - Exchange clears all the spreads every day in their test environment, even though they have not yet reached their expiry. While this will not happen in Production, TT is still adding a fix to clear such inactive spreads from the TT environments too. - TT features of TTW Charts, ASE, Aggregator and .NETSDK
