How to Keep a Local Basis Log That Survives Contract Rolls and Missing Bids
A practical evergreen field note with United States context on how to keep a local basis log that survives contract rolls and missing bids: what to compare, which official sources to open, and which limits to keep visible.
The question
What belongs in a durable local grain basis history?
Begin with one dated worksheet and record location, commodity, delivery window, cash bid, futures contract, calculated basis, timestamp, source, and data-state flags. That makes assumptions visible before the next call or operating decision. Keep this limit in view: missing observations and futures rolls must remain visible rather than being filled as zero.
