Risk
Root confusion
Using SPX and SPXW interchangeably can distort settlement assumptions.
The practical parsing rule
If a query names SPX but asks about a non-standard weekday date, the intent is often SPXW. A robust options tool should show the listed series and not only the broad index family.
For historical research, preserve root, expiration, settlement style, and timestamp. Those fields determine whether the data can be compared to another contract safely.
