What the estimate captures
Close-location logic: a candle closing high in its range with strong volume probably contained net buying pressure. Aggregated and smoothed, this yields a serviceable lean gauge, quick context for which side has been winning the recent auctions. On markets without classified tape, spot gold included, it is the only pressure read available, which is a fine reason to use it and no reason to oversell it.
The failure modes
The estimate misfires exactly where precision matters most: absorption candles, where heavy selling met a wall and price closed high, read as buying pressure while the real story was the wall; and thin-market wicks, where close location reflects vacuum, not victory. These are precisely the moments real tape data disagrees with the estimate, and the disagreement is the information.
Labels as ethics
Our chart carries such a gauge, permanently labelled an estimate, alongside genuinely classified tape tools labelled as tape. The rule generalises: any tool's trustworthiness starts with whether it admits its data class. A mislabelled estimate is not a weak tool, it is a confident wrong answer waiting for the moment you rely on it, the theme running through all our volume honesty notes.
FAQ
Are pressure oscillators useless then?
No, they are quick, universal context for recent auction lean. They earn distrust only when promoted from estimate to measurement.
When do estimates and real tape disagree most?
At absorption events and thin-market extremes, which is unfortunate, since those are the highest-value moments. Where both exist, tape outranks estimate.
How should I weight a pressure gauge in decisions?
As minor corroboration after structure and levels: agreement adds a little confidence; disagreement warns you to look closer at the tape or the level.
