ToolTack Heat Map & Volume Scanner
Liquidity Heatmap & Real-Time Volume Surge Detection for TradingView
See where liquidity is parked and when it’s being hit. Heat Map & Volume Scanner overlays a 31-level thermal map of historical volume on your chart, marks live volume surges, and tracks buy / sell imbalance in a single dashboard — so you can read where the market is most likely to react.
01 Quick Summary
Heat Map & Volume Scanner is an invite-only TradingView indicator built around two ideas: where has volume actually traded, and when is current volume blowing out the average? It builds a 31-level liquidity heatmap from historical close-by-volume data, projects a thermal profile on the right of the chart, and overlays real-time volume surge markers wherever volume breaks above your chosen multiple of average.
02 Overview
Most volume profiles show you bars on the side. Heat Map & Volume Scanner paints volume directly onto price space as a heatmap, with green zones flagging support (volume below current price) and red zones flagging overhead resistance (volume above current price). Brighter bands are where the most volume has traded — the levels markets care about most. A high-volume node (HVN) box is auto-pinned to the right with the exact volume figure.
How it supports your process: The heatmap shows you where the market has built liquidity. The scanner shows you when participants are stepping in. Used together, they help you separate routine bars from the moments when size is hitting a level — whether absorption, breakout, or capitulation.
Three depth profiles let you choose between short-term structure (100 bars) and broader distribution (600 bars). Three sensitivity modes adjust contrast for clean read in any chart background. Add the Volume Momentum Scanner on top to mark every bar that prints 2x (or more) the recent average volume — with bullish surges marked below the candle and bearish surges marked above.
03 Key Features
Splits the chart range into 31 horizontal bins and shades each by historical volume. The brighter the band, the more activity has traded at that price — a visual map of liquidity built directly into the candles.
Bands below current price render in ToolTack green (support liquidity, buy-side). Bands above render in red (overhead resistance, sell-side). Direction is recalculated as price moves.
The single price level with the most concentrated volume is auto-tagged on the right of the chart with its volume figure — the strongest gravitational level in your lookback window.
A vertical 31-band profile is rendered to the right of the latest bar so you can read the full liquidity distribution at a glance — fading further from the current price.
Shallow (100 bars) for short-term structure, Balanced (300 bars) for medium-term context, Deep (600 bars) for broader historical distribution.
High Contrast for crisp visual separation, Balanced for default rendering, Smooth for softer gradient blending on busy charts.
Marks every bar where volume exceeds the average by your chosen multiple (default 2.0x over 20 bars). Bullish surges are tagged below the candle, bearish surges above — both with strength tooltips.
Top-right table breaks down total buy liquidity vs sell liquidity, the dollar / unit imbalance, and labels the broader bias as SUPPORT or RESISTANCE based on where volume has concentrated.
Cumulative count of every bullish and bearish volume surge in view, with an at-a-glance dominance read (BULLS / BEARS / NEUTRAL) so you don’t have to count markers yourself.
Optional toggle removes the heatmap colouring around the current candle so live price action stays visible. Toggle off if you prefer a fully-painted background.
Re-colour support, resistance, bullish surge and bearish surge markers from the inputs panel — useful for matching your chart theme or for colour-vision accessibility.
04 How to Use Heat Map & Volume Scanner
Add it to TradingView
Open the Indicators menu → Invite-Only Scripts → select Heat Map & Volume Scanner [ToolTack] and apply it to your chart.
Choose a Profile Depth
Balanced (300 bars) is the recommended default. Switch to Shallow for scalping or intraday session focus, Deep for swing trading and broader structural context.
Set the Thermal Sensitivity
Balanced works on most charts. Use High Contrast if zones look washed out, or Smooth if the bands are too “loud” over your candles.
Read the Heatmap
Green = liquidity below price (potential support / buy-side). Red = liquidity above price (potential resistance / sell-side). The brighter the band, the more volume traded there. The labelled HVN box is the gravitational anchor.
Tune the Volume Surge Threshold
Default is 2.0x the 20-bar average volume. Raise it (e.g. 3.0x) to filter for only the most extreme surges, or lower it (e.g. 1.5x) to track all elevated activity.
Watch the Dashboard
The top-right table summarises everything: BUY LIQ vs SELL LIQ totals and percentages, the net IMBALANCE labelled SUPPORT or RESISTANCE, and the Bull / Bear surge counts with the dominant side called out.
Combine with your own analysis
Use bright heatmap bands as objective S/R levels. Use surge markers as confirmation or warning signals at those levels. The heatmap is context; surges are events. Always cross-check with your bias and risk plan.
05 Strategy Ideas
Educational examples only — always test before using real capital.
Bullish Surge at Green HVN
Price retraces into a bright green liquidity band and a bullish volume surge prints below the candle. Treat it as evidence buyers are defending the level — consider continuation entries above the surge bar with stops below the band.
Bearish Surge at Red Band
Price grinds up into a thick red overhead band and a bearish volume surge fires above the bar. Often signals supply being unloaded into strength — tighten longs or wait for failure for short setups.
Surge Through HVN
A bullish or bearish surge that prints as price clears the labelled high-volume node often signals real participation in the move. Cleaner than chasing breakouts on price alone.
SUPPORT vs RESISTANCE Read
When the dashboard imbalance is heavily skewed (e.g. 99% BUY LIQ as in the NVDA chart example), the bulk of volume sits below price. Use that as a directional bias filter on trend-continuation setups.
Bull vs Bear Surge Count
When Bull surges materially outnumber Bear surges (or vice versa) in your visible range, momentum is one-sided. Combine with the imbalance read for a structural + behavioural bias.
Counter-Trend Surge
A single oversized bearish surge inside a bright green band after a strong up-leg can mark short-term exhaustion. Wait for confirmation on the next bar before fading — never trade the marker in isolation.
Reminder: these are educational frameworks, not trade recommendations. Heat Map & Volume Scanner is a context tool — it surfaces information, it doesn’t predict outcomes. Always validate on historical data and in a simulator before risking capital, and size positions within your risk plan.
06 Best Tools to Combine With
Heat Map & Volume Scanner gives you where liquidity sits and when it’s being hit. Pair it with directional and structural tools to convert that context into actionable plans.
Stack large-print bubbles directly onto heatmap bands to see when size hits a liquidity zone — the strongest absorption / distribution read.
Confirm bright heatmap bands against BOS / CHoCH and Fib zones for higher-conviction S/R reads.
Use VWAP as your fair-value anchor and the heatmap as your liquidity skeleton — together they map where institutional execution gravitates.
Filter surge markers with momentum agreement to skip counter-trend noise, especially in High Contrast mode.
Calibrate the surge multiplier and stop placement to current volatility regimes for cleaner outlier detection.
Standardise stops, targets and position sizing on every heatmap-informed trade — context without risk control isn’t an edge.

09 Frequently Asked Questions
Is this a true volume profile or something different?
It is a close-by-volume distribution rendered as a heatmap rather than a horizontal-bar profile. Each of the 31 bands represents volume that traded near that price across the lookback window. It is structurally similar to a volume profile, but visualised inside the chart instead of as a sidebar histogram.
Which Profile Depth should I pick?
Shallow (100 bars) for short-term intraday structure, Balanced (300 bars) as the recommended default, Deep (600 bars) for swing trading and broader context. You can switch on the fly to see how zones evolve across timeframes.
Why does the same band sometimes look red, sometimes green?
Colouring is dynamic: any band above current price is treated as overhead resistance (red), any band below is treated as support (green). As price moves through a zone, the same liquidity flips role — which is exactly how traders treat S/R in practice.
What does the SUPPORT / RESISTANCE label on the dashboard mean?
It compares total buy-side liquidity (volume below price) with total sell-side liquidity (volume above price). If most of the lookback’s volume sits below price, the dashboard labels the imbalance SUPPORT. If most sits above, it labels it RESISTANCE.
How is a volume surge defined?
A bar is a surge when its volume exceeds the rolling average (default 20 bars) multiplied by your threshold (default 2.0x). Bullish surges (close > open) are tagged below the candle in green; bearish surges (close ≤ open) are tagged above in red.
Does this guarantee profitable trades?
No. Heat Map & Volume Scanner is an analysis utility. It surfaces information; it does not predict markets and does not guarantee outcomes. Always combine with your own analysis and risk plan.
Does it work on all assets and timeframes?
It works wherever TradingView provides volume — stocks, ETFs, futures, crypto and most forex feeds (with the caveat that forex volume is tick volume, not true volume). All timeframes from intraday to monthly are supported.
