Is there a FID that represents the 'period' of an option - i.e. weekly/monthly/quarterly?

For context:

Corn early expiry options come in weekly and monthly flavours:

Corn Weekly Options Contract Specs - CME Group

The RIC is the only way that I can see to determine whether the option is monthly or weekly - i.e. for a call with strike 235 for corn:

C235F24 is monthly

C1W235F24 is weekly

The expiration date isn't always enough, especially when handling ~100,000s RIC subscriptions.

Ideally, there would be a specific FID that would state whether the option was monthly, weekly, quarterly etc.

Hi @matthew.walmsley

You can use refinitiv-data library to get the expected results like below:

import refinitiv.data as rd
rd.open_session()

rd.discovery.search(
filter = "RIC in ('C235F24' 'C1W235F24')",
select="RIC, PeriodicityCode")
