Not really sure yet how to get this to work. If I try this ON CONFLICT clause, I get a db error
[ERR] MKT: Error updating API data collector: pq: there is no unique or exclusion constraint matching the ON CONFLICT specification
Or maybe the two-column index isn't worth it. The PostgreSQL docs say to use multi-column indexes sparingly.

Why not just have three tables, one for each candle duration?
