Open Interest
Open interest is the total of all futures and/or option contracts en-
tered into and not yet offset by a transaction, by delivery, by exercise,
etc. The aggregate of all long open interest is equal to the aggregate of
all short open interest.
Commercial and Non-Commercial Traders

mission, the trader is classified either as “commercial” or “non-
commercial.” All of a trader’s reported futures positions in a com-

contracts in that particular commodity for hedging. To ensure
that traders are classified with accuracy and consistency, Com-
mission staff may exercise judgment in re-classifying a trader
if it has additional information about the trader’s use of the
markets.
