Improvements

ADL

This is to address logic improvements within our Market Making Algo (MMA) suite, specific to the following globally deployed algos:

Bid Ask Theo
Direct Entry
Reference Market
Single Theo

Improvements within these MMA's are to address the following:
- Addressed a situation where initial cover orders were not sent out unless the Net Pos was >=1. Re-sequenced the "Quote Order" fills such they update the net pos block before they hit the branch block
- Improved the "fill throttle" logic to ensure "Order:price requote" discrete message is kept instead of circumventing the fill throttle.

Primary issues were within the SafeToPlace orders group block. Qty increases would set all checks true and generate a message that would ultimately place an order even when "Manual Requote" was enabled or if a fill was being throttled. Addressing these led to a number of obstacles which led to the following necessities.
- For on start generator, one path needed to have only an initial on start while another path required all subsequent starts (resumes) but must exclude the initial start message.
- This was achieved by using Value extractor "Initial start tracker" in tandem with branch block "Initial start?"
- Initial start message needed to be tagged so logic within virtualization could differentiate between initial start and subsequent start messages.
- This was achieved with value injector "Initial start tracker" injecting "1" into userfield1 and value extractor "Initial start marker" placed just inside the virtualized block.

An indication of active fill throttling was required to stop qty increases from triggering a new order.
- "fill throttled" value accumulator was added in the previous change and used in this change as well to determine whether or not there is active fill throttling.
- Logic was added to clear it when the fill throttle time elapsed, or if throttling was active when the user pauses the algo, to clear it on resume.

Within the "SafeToPlaceOrder" group the following was added:
- A formula block with the following equation to check manual requote setting, intial start marker and active fill throttle.
(!Manual Requote OR Initial start marker =1) AND fill throttled !=1
- If the above evaluates to true, then the a message that would ultimately place an order is sent.
- If the above evaluates to false, the message that would place an order will not be generated until the user hit the manual requote button.

Improvements

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.
