Why implied volatility by expiry is empty?
The input data (bid/ask) across strikes and expiration dates form the basis of our implied volatility (IV) estimates. If the input data is inconsistent or sporadic, it negatively impacts the quality of the IV estimates we produce.

In these cases, we stop producing estimates rather than produce numbers we have low confidence in. When this happens, you may not see any data presented on this screen…
