Note that we may also need some indication of whether or not the exchange itself publishes standardized terms for an option or other contract that are included by reference in all of those contracts that we should have a reference for.
From the CFI standard:
Standardized/non-standardized (indicates whether the terms of the contract
are standardized or not):
- S Standardized (the underlying instruments, exercise price, expiration date and contract size of the options are standardized; these options are traded on special option
exchanges)
- Non-standardized (options traded on option exchanges which have non-standard delivery or expiry terms)
