Description
Expected Behavior
The Exercise-Settlement Function uses the "opening sales price" for SPX.
https://cdn.cboe.com/resources/spx/spx-fact-sheet.pdf
Actual Behavior
All options use the close of the underlying.
Potential Solution
Review implementation.
Reproducing the Problem
I suggest placing the orders to Interactive Brokers manually (for SPX, VIX, NDX) on Feb 16th to observe the result. We have verified for SPY and SPXW
to confirm that "opening sales price" is the open value (since it's not tradable) of SPX

Research direction
Start by reviewing the exercise-settlement implementation and the SPX fact sheet linked in the issue. Compare the current use of the underlying close with the SPX opening sales price, using the reported SPX, SPXW, SPY, VIX, and NDX behavior as context. Done means SPX exercise-settlement values use the opening sales price while other instruments retain their appropriate behavior.
