Volume Bubble Map [Herman]

9 saat önce

Volume Bubble Map [Herman] visualizes relative volume strength directly on the price chart.

Each candle gets a bubble at its average price (hlc3).
Bubble size and intensity reflect how unusual that bar’s volume is compared to recent history, helping you spot activity clusters, spikes, droughts, and tempo shifts at a glance.

What it shows:

σ -scaled bubbles: The script normalizes volume with a 200-bar standard deviation and classifies each bar into five bands:
-Tiny < 1σ
-Small 1–2σ
-Normal 2–3σ
-Large 3–4σ

Huge ≥ 4σ
Bullish bars use the “Up Color,” bearish bars the “Down Color.” A gradient is applied so higher n_vol appears more intense.

On-chart stats table:

-Selected LookBack window
-Average and Maximum volume (+ price at max)
-Count and percentage of bars in each σ bucket (Tiny → Huge)
-Light/Dark theme and position controls for readability

Optional labels for extremes: If a bar is ≥ 4σ, the indicator can print its exact volume value above the bubble (color of the text is configurable).

Inputs & UI

-LookBack (default 250): number of most recent bars considered in stats and display.
-Display Volume Bubbles: global toggle to show/hide all bubbles.
-Volume Bubbles Size Control: enable/disable each σ band (Tiny/Small/Normal/Large/Huge).
-Up/Down Color: base colors for bullish/bearish bubbles.
-Bubble Label Text Color: text color for ≥4σ volume labels.
-Show Stats Table / Table Position / Table Theme: control the on-chart table’s visibility, corner placement, and theme (Dark/Light).

How it works (method)

-Computes stdev(volume, 200) and creates a normalized volume metric:
n_vol = volume / stdev(volume, 200).
-Restricts drawing to the LookBack window for clarity and performance.
-Draws one bubble per bar at hlc3 with size determined by the σ band and color by bar direction.

Updates the stats table on candle close (non-repainting): averages, maxima, and σ-bucket counts/percentages are recalculated for the current LookBack window.

Typical use cases

-Spot high-activity nodes: quickly see where the market concentrated participation within your session.
-Confirm momentum bursts: clusters of Large/Huge bubbles often mark acceleration phases.
-Context for reversals/sweeps: unusual volume near key levels can add confluence to price action reads.
-Session studies: combine with your session overlays.

Notes & limitations

Works on any symbol/timeframe that provides OHLCV.

Uses only bar volume available in TradingView; it does not access Level-2, DOM, or tick-by-tick executions.

Non-repainting: statistics update on confirmed bars.


Summary: This indicator provides a statistical visualization of bar volume, not live order-book data. Use it to contextualize activity and spot volume anomalies within TradingView’s dataset; use specialized orderflow tools if you need actual order executions and depth.
