Constructing weekly participant positioning ledgers

What the weekly snapshot records

A weekly positioning report records net open interest, overnight longs minus overnight shorts, on most U.S.-listed futures. Open interest is the count of futures contracts still held after the close, so trades that are flattened in the same session do not appear.

The underlying count is taken at Tuesday's close even when the public figures appear later in the week, typically Friday afternoon. That weekly snapshot is a commitment of traders record of who is net long or net short overnight futures and options.

How the three buckets are assigned

In its simplest construction the report splits interest into reportable and nonreportable groups, then splits reportable accounts into commercial hedgers and large speculators. That split is market participant analysis: traders are grouped by economic role so a single trade can be read against who is already positioned and by how much.

A reportable position is a holding large enough that a single person or fund exceeds preset, market-specific size thresholds. After that threshold is crossed, the associated firm sends a daily tally of those oversized accounts. A nonreportable position sits below those thresholds and is typically associated with smaller speculative accounts.

Commercial hedgers are end-users or producers whose futures offset commodity-price, interest-rate, or exchange-rate exposure rather than express a standalone directional bet. The large-speculator bucket holds high-capital, large-size reportable directional accounts, often a fund or advisor. The nonreportable bucket is described as smaller speculative accounts typical of most retail readers.

How net position is built

For each of the three participant groups, net positioning is built by subtracting short open interest from long open interest. The resulting net position shows both direction and magnitude.

The degree of bullish or bearish net positioning in each group is presented as a construction input for judging whether a trend looks like it is forming or wearing out.

Using the ledger as regime context

Editorial reading: once each bucket has a signed net position, the commitment of traders snapshot becomes a constructed overlay beside the trade. It shows how commercial hedges, large reportable speculation, and smaller nonreportable accounts are already set.
