Volume confirmation when open interest disagrees
Commodity charts often show price breaking a level while open interest tells a quieter story.
Equity-trained readers lean hard on volume bars. Commodity markets add open interest — the count of open contracts — which can rise or fall while price prints a dramatic break.
In lessons we treat disagreement as a pause signal, not an automatic fade. A breakout on light volume with falling open interest may simply be short covering or thin liquidity into a holiday. A break on rising open interest and expanding volume earns more attention on the annotation sheet.
Students keep a two-column note beside the chart: “participation agrees” or “participation doubts.” The label does not dictate the trade; it dictates how large a claim they are allowed to write in the trade plan.
Case packs for copper and crude include sessions where price cleared congestion while open interest slipped. The exercise is to rewrite the plan’s confidence language without inventing a contrary prophecy.
