Buy/Sell Pressure Meter [AGPro Series]Buy/Sell Pressure Meter
🔹 Overview
Buy/Sell Pressure Meter is a volume-flow analytics tool that quantifies the tug-of-war between buyers and sellers on every bar and on a rolling basis. Unlike traditional volume delta indicators that only plot raw bar-level buy minus sell, this tool layers four complementary lenses into a single oscillator: rolling pressure trend, imbalance streak tracking, intraday pressure shift count, and session-accumulated dominance. A subtle price-pane background tint gives a Bookmap-light read on intraday participation that works across crypto, futures, and liquid equities — without requiring tick-level order flow data.
🔹 Unique Edge
Most volume-delta scripts answer the question "which side was bigger on this bar?" This one answers a different, more useful question for intraday traders: "who has been in control, and how stable is that control?"
• Rolling Pressure Trend — a moving average of buy and sell pressure separately (dual histogram), so you see structural bias, not just bar-to-bar noise.
• Imbalance Streak Tracking — counts consecutive same-side dominant bars and labels only the final length of each significant streak at the moment the streak breaks. No per-bar label spam, one clean marker per event.
• Intraday Pressure Shift Count — how many times the rolling dominant side has flipped since session open. High shift count = rotational day. Low shift count = trending day.
• Session-Accumulated Net Delta — cumulative bull vs bear contribution since the day began, independent of the rolling window.
• Price-Pane Bookmap-Light Tint — a very high-transparency background tint paints the main chart pane when one side is rolling-dominant, so you see control visually without leaving the price chart.
These five lenses together are deliberately designed not to overlap with raw volume-delta or cumulative-volume-delta indicators. They describe the character of participation, not just its magnitude.
🔹 Methodology
Because standard chart data does not include true tick-level order flow, this script uses a widely-accepted proxy: up-bar volume is attributed to buy pressure, down-bar volume to sell pressure, and doji volume is split evenly. This is explicitly a simulated bias — not real bid/ask flow — and the script labels it as such in the panel.
From that proxy:
1. Current-bar bull pressure percentage = buyPressure / (buyPressure + sellPressure) × 100.
2. Rolling pressure = SMA of buy and sell pressure over the user-defined window (default 20 bars).
3. A bar is classified bull-dominant when its bull pressure percent exceeds the dominance threshold (default 55%), and bear-dominant at the mirror level.
4. Streaks count consecutive bars of the same classification and reset when a neutral or opposite bar prints. Peak length is captured at the moment of reset and optionally labelled on chart.
5. Pressure shifts compare the current rolling dominant side against the last confirmed non-neutral dominant side; a change increments the intraday shift counter (only on intraday timeframes).
6. Session delta is the cumulative net delta since the last daily rollover.
🔹 Signals & States
• Dual histogram — buy pressure (teal, upward) and sell pressure (pink, downward) plotted as rolling averages.
• Net delta center line — accent-colored line showing rolling buy minus sell.
• Price-pane background tint — subtle teal or pink when one side is rolling-dominant, gives a Bookmap-light feel without obscuring candles.
• Oscillator-pane echo tint — even more subtle tint mirroring the dominant side in the indicator pane.
• Shift markers — triangles on the pane when the dominant side flips.
• Streak peak labels — plotted only at streak termination, showing final length (e.g. "Bull 7").
• Alerts — pressure shift to bull, pressure shift to bear, bull imbalance streak, bear imbalance streak.
🔹 Key Inputs
Calculation:
• Rolling Pressure Length — default 20. Higher = smoother, slower reaction.
• Minimum Streak To Highlight — default 3. Used for alerts.
• Dominance Threshold — default 55%. Share of total pressure needed to classify a bar as dominant.
Visuals:
• Tint Price Pane On Dominance — toggles the Bookmap-light effect on the main chart.
• Show Streak Peak Labels + Minimum Streak Length To Label (default 5) — controls chart cleanliness.
• Show Pressure Shift Events — triangle markers on shifts.
• Background Tint Transparency — default 94, adjustable 80-99.
Panel:
• Panel Location, Theme (Dark / Light), Font Size, Label Font Size — all default to Normal and fully configurable.
🔹 How To Use
This is an analytical tool, not a standalone trading system. Typical use cases:
• Confirmation — when price breaks a structure level while the rolling net delta is strongly in the break direction and a streak is in progress, the break has participation behind it.
• Exhaustion — a long bull streak peak followed by a rolling shift to bear, or vice versa, often marks the end of the current impulse.
• Regime read — a day with many intraday pressure shifts is rotational; a day with 0-1 shifts is directional. Adjust your playbook accordingly.
• Companion to S/R, supply/demand, and volume profile tools — use the streak peak and shift events as a participation filter when price interacts with a zone.
Best results on liquid instruments with meaningful bar-to-bar volume variation. Low-volume illiquid tickers produce noisier readings.
🔹 Limitations & Transparency
• The buy vs sell attribution is a proxy derived from bar direction and bar volume. It is not real order flow, Level 2, or tick data. Bookmap, CVD from exchange feeds, and footprint tools access information that bar-level scripts structurally cannot replicate.
• On instruments or timeframes where many bars close near their open (doji-heavy regimes), proxy-based attribution becomes less informative.
• The intraday shift counter is only meaningful on intraday timeframes; on daily-and-above timeframes the panel explicitly shows this as n/a.
• The script is non-repainting on closed bars. Intrabar values update in real time and may change until the bar confirms.
• Pressure shifts and streaks describe past and current state. They are not predictions of future price.
🔹 Risk Disclosure
This script is provided as an analytical tool for educational and research purposes. It does not constitute financial advice, a trading signal, or a recommendation to buy or sell any asset. Past performance of any pattern, streak, or shift event does not guarantee future results. Users are solely responsible for their own trading decisions and risk management. Always combine any indicator with broader market context, position sizing discipline, and your own due diligence.
