What a positive or negative reading means
A positive Net/OI means the cohort holds more long contracts than short; negative means the opposite. The magnitude shows how concentrated the position is relative to the market's total open interest. Because the series is normalized by open interest, it stays comparable as the contract grows or shrinks over the full history. Extremity is judged against the cohort's own historical range (see the percentile cell), not against a universal threshold. Observed ranges differ sharply between contracts.
