ADL

Further to the Release Note dated 07/28/2025 (with Ref 177412)

Addressed an issue within the existing MinVol algo logic that ensures upon recovery, the logic should never place a buy and sell child order in the same instance.

The fix has now been deployed to UAT and Production environments under its original name "MinVol". The amended version of this algo will be globally available to users within the "Shared with me" section of the algo list panes.

A copy of the MinVol ADL logic is also available from the ADL Canvas.

Options

We have now embedded the functionality previously available in the TT Uncovered .NET SDK application into the TT front end (aka TTW and TT Desktop), including the ability to create and execute CME Covered UDS instruments and automatically unwind allocated futures, as well as workflow integrations with existing TTW widgets. This feature is targeted towards buy-side traders trading CME options seeking large liquidity or price improvement opportunities, in particular those trading interest rate options, and sell-side (bank or agency) traders executing such trades on their clients behalf. Please see our documentation for full details.
