Issue with resolve_chain Returning Malformed RICs for Heating Oil Futures

Siva

Hello All,

I'm using the TRTH API "Search/HistoricalChainResolution" to retrieve resolved RICs for the Heating Oil futures chain (0#HO-1M:). However, I'm noticing that the resolved RICs sometimes appear incorrectly formatted.

Query Details:

• Chain RIC: 0#HO-1M:
• Start Time: datetime(1996, 1, 1, 0, 0, 0, 0, tzinfo=None)
• End Time: datetime.now()
• Issue: Instead of returning expected RICs like HOU7-V7, the API is returning malformed RICs such as HOU7-HOV7.

Questions:

1. Why is the API returning incorrect RIC formats for this chain?
2. Have there been any changes in the way Heating Oil futures chains were structured historically that could explain this behavior?
3. Is there a recommended way to ensure correct resolution of RICs for historical futures data?

Any insights would be appreciated!

Thank you for reaching out to us.

I used the Historical Search on the DSS Web GUI to resolve the 0#HO-1M: chain RIC.

The results don't have the HOU7-HOV7 RIC.
