Constructing auction fuel from volume and open interest

A three-input auction ledger

The archive workflow builds a three-input auction ledger. The first input is price direction. The second is volume magnitude. The third is the open-interest change, treated as sponsorship fuel.

Sponsorship fuel is an open-interest change read as added or withdrawn participation that either sustains a price direction or strips it of follow-through. Total volume is the contracts traded in a session across every listed contract month combined. Total open interest is the outstanding long and short positions across all months that have not yet been offset.

How the inputs are read

Volume-price analysis combines the session's price direction with volume magnitude to turn a chart condition into a checkable hypothesis about whether the move is sponsored.

Open-interest analysis then reads whether outstanding positions expand, contract, or stay flat as the test of whether new sponsorship entered or left the auction.

Volume confirmation uses heavy versus light volume as a filter that either accepts a price and open-interest reading or marks the move as thin and likely short-lived.

How an advance is graded

An advance on low volume with unchanged open interest is treated as only slightly stronger, and thin volume is taken to mean the rally attempt may not last. Volume confirmation marks that construction as thin.

An advance on high volume with unchanged open interest is read as large-scale new buying that replaces old longs, remaining strong until prices are high enough to attract a new group of short sellers.

An advance on high volume with rising open interest is presented as the strongest bullish construction, confirmed further when price closes toward the high of the session range.

An advance on high volume with falling open interest is treated as forced short covering that leaves the auction weak after a brief lift, generally lasting one to three days. That pattern is a short-covering lift: an advance driven by forced short liquidation and falling open interest rather than by new long sponsorship.

How a decline is graded

A decline on low volume with unchanged open interest is treated as slightly strong because the markdown lacks follow-through and selling is viewed as having climaxed.

A decline on high volume with unchanged open interest is associated with concentrated, fund-style transfer of contracts and bargain hunting that can reverse into a sharper drop if prices then move against those buyers. That reading is a bargain-hunting transfer: concentrated buying on a high-volume pullback with unchanged open interest, often associated with large-account activity that can exit quickly if prices then turn against those buyers.

A decline on high volume with rising open interest is presented as the most bearish construction, with new sellers adding at any price and losing longs delaying exit.

A decline on high volume with falling open interest can mark a temporary or double bottom because long liquidation and short profit-taking remove immediate downside pressure, even though the larger trend is still down.

Editorial reading of the next order

Editorial interpretation: fill the three inputs first, then ask only whether the next order would join sponsored participation or step into a move that has already lost it.

A TradersWeek editorial reading treats the strongest bullish construction, an advance on high volume with rising open interest, as a refueled auction. It treats the most bearish construction, a decline on high volume with rising open interest, the same way in the opposite direction.

The same editorial reading treats a short-covering lift and a thin, unchanged-open-interest rally as exhausted participation on the upside. A low-volume decline with unchanged open interest is read as selling that has already climaxed. A bargain-hunting transfer is read as a temporary bid that can leave quickly if price turns against those buyers.
