Stock delisting date or futures contract expiration date
Notes
When using CSI Futures continuous contract data, InfoExpiry returns the expiration date of the individual contract that would be held on the date of the current bar for which the formula is being evaluated.
When using Norgatefutures data, InfoExpiry is only provided for individual contract symbols.
With Norgate stock data, InfoDelist shows the delisting date for delisted symbols.
To provide this field in your own SymInfoFile, use the DelistDate column.
