Rolling Volume Delta
█ OVERVIEW
Rolling Volume Delta (RVD) estimates net buying vs. selling pressure per bar, then weights that pressure by how much price actually moved — so a strong directional bar counts for more than a quiet, indecisive one. The result is summed over a rolling window, smoothed, and normalized against total volume so it reads consistently across different instruments and volume regimes.
█ CONCEPT
Most volume delta tools estimate buy/sell pressure and stop there. RVD adds one more step: it multiplies each bar's estimated delta by the magnitude of that bar's price change. The logic is that a bar where buyers dominate AND price actually moved higher represents more conviction than a bar with the same buy/sell split during a flat, choppy stretch. That weighted delta is then summed over a rolling window and smoothed, so the final line reflects sustained pressure rather than single-bar noise.
█ HOW IT WORKS
1. Buy/sell split: each bar's volume is divided between buy and sell based on where the close landed within that bar's high-low range (close near the high = buy-weighted, close near the low = sell-weighted).
2. Price weighting: that delta is multiplied by the percentage price change over a configurable lookback, so bars with bigger moves are weighted more heavily.
3. Rolling sum: the weighted delta is summed over a configurable lookback window.
4. Smoothing: an EMA is applied to reduce noise.
5. Normalization: the smoothed result is divided by total volume over the same window and expressed as a percentage, keeping the scale comparable across tickers and sessions.
█ HOW IT DIFFERS FROM OTHER VOLUME DELTA SCRIPTS
Other delta oscillators calculate buy/sell pressure and smooth it directly. RVD's price-weighting step means the indicator isn't just "how much delta happened" but "how much delta happened relative to how much the market actually moved" — filtering out high-volume, low-conviction chop from the signal.
█ SETTINGS
- Lookback Length — bars summed together for the rolling delta. Longer = smoother, slower.
- Smoothing — EMA length applied to the rolling sum.
- Momentum Lookback — bars back used to measure price change for weighting. Higher values emphasize sustained moves over single-bar spikes.
As bars carry more information on their own (higher timeframes), less summing and smoothing is needed for a clean read. Within any timeframe, trending conditions benefit from longer/smoother settings that confirm sustained pressure and filter chop, while ranging conditions benefit from shorter/quicker settings that catch reversals near the extremes at the cost of more false flips in the middle of the range.
Suggested starting points:
Timeframe | Condition | Length | Smoothing | Momentum Lookback
5-30 min | Trend / Price Discovery | 14-20 | 3-5 | 1-2
5-30 min | Range / Accumulation | 8-10 | 1-2 | 1
1-4 hour | Trend / Price Discovery | 10-14 | 2-3 | 2-4
1-4 hour | Range / Accumulation | 6-8 | 1-2 | 1-2
Daily+ | Trend / Price Discovery | 8-10 | 2 | 3-5
Daily+ | Range / Accumulation | 5-6 | 1 | 2
These are included in each input's tooltip in the settings popup as well.
█ NOTES
This is a volume-estimation tool based on standard OHLCV data (bar range and close position), not true tick-level buy/sell data — most retail data feeds don't provide that, so this is the same practical tradeoff most public volume delta scripts make. It's intended as a context tool for reading order flow alongside price action, not a standalone signal generator.
