Price and Volume Trend (PVT) — a running sum of the close's percent change times volume, starting at 0 (the absolute level is meaningless, as for OBV — only the shape matters). A bar contributes when it has volume and a previous close; a bar with volume but no previous close reads the sum so far (0 on the first bar). A bar without volume, one whose previous close is 0, or one whose contribution or resulting sum leaves the double range or lands on its largest value is null and the sum stays where it was, resuming on the next bar — against the previous bar's close, gap or not, as OBV does. The sum is compensated (Neumaier): contributions are fractional and the history is unbounded, so a naive sum would drop small terms next to large ones. The running sum has no bounded lookback, so this declares no head door.
