Composite HVN/LVN NodesComposite HVN/LVN Nodes
Most volume profile tools show one session at a time. This one accumulates high and low volume nodes across many sessions into a single map, so the prices that keep reappearing stand out from the ones that showed up once.
Each session is profiled separately. Its nodes are extracted and folded into a running composite where repeat sightings reinforce each other, unreinforced levels decay away, and levels price has torn through get demoted. Zones are shaded by relative strength — the darkest bands are the strongest currently on the map.
HOW IT WORKS
Detection finds a run of contiguous rows clearing the threshold, then anchors the zone on that run's actual volume peak. Anchoring on the first qualifying row instead biases every zone toward the lower peak of a multi-peak shelf.
Merging takes the union of two overlapping bands rather than the average of their centres. Averaging places the result in the valley between two shelves, covering neither.
Decay runs at every session close. A node that stops being reinforced fades and is eventually dropped.
Invalidation cuts a zone's weight hard when a single bar rips clean through it.
Conflict resolution removes one of any overlapping HVN/LVN pair. A price cannot be both a shelf and a gap.
Profiles are built from 1-minute intrabars rather than chart bars, so the map is the same on 1m as on 1h. Without this, coarse bars smear volume across rows they only passed through.
DEFAULTS ARE TUNED FOR NQ
Most thresholds are percentages of session range or session volume, so they travel between instruments reasonably well. The session times and the LVN threshold do not.
Sessions: Globex (1800-0930) and New York (0930-1700). For equities, use a single 0930-1600 and disable the other. Sessions must not overlap.
Resolution: 1 minute. The most important setting for consistency. The "Intrabars/bar" readout in the status line shows whether it is active; 0 means it has fallen back to chart bars, which happens past roughly 100k intrabars of history.
Detection: 200 rows, sensitivity 6, HVN 70%, LVN 10%. Roughly one row per point on a typical NQ session range. The thresholds are asymmetric on purpose: 70% is permissive enough to catch shoulders as well as the POC, while 10% is strict because on a liquid instrument nearly everything trades a little and a loose setting produces gaps that aren't really gaps. On thinner instruments 10% may find nothing.
Node width: max 12% of range. Mainly restrains LVNs. At a 10% threshold a genuinely dead pocket can run a long way, and without a ceiling one gap swallows half the range.
Volume weighting — each session's contribution is scaled by how active it was against a rolling 20-session average, capped at 3x either way so one event day cannot dominate. Sessions below 35% of average volume are skipped entirely, which filters holidays and half days on NQ. Set to 0 to disable.
Composite: half-life 50 sessions. Note that is sessions, not days: with both enabled that is two per weekday, so about five trading weeks. Halve it for a faster-moving map.
Conflicts: stronger wins. The lighter of an overlapping pair is removed, ties going to the HVN, since volume that demonstrably traded is harder evidence than volume that didn't. Zones that merely touch are left alone — an HVN against an LVN is a real structure, the edge of a shelf against a gap.
Archive: off. When on, invalidated nodes freeze in place with a dashed border instead of disappearing, so you can see where a level sat and how long it lasted. Useful for review, cluttered live.
ADAPTING IT
Start with the session times; everything depends on those being right. Then check LVN detection, which assumes NQ-like liquidity. If the map is too sparse or too crowded, adjust "Drop below weight" and "Max nodes kept".
NOTES
Nodes are computed at session close and are not recalculated afterwards, but their appearance changes as weights decay and merge — shading is relative to the strongest node currently on the map, not an absolute scale.
TradingView caps drawing objects at 500 boxes. Active and archived nodes share that budget.
This is an analysis tool, not a signal generator. It marks prices where volume repeatedly concentrated or repeatedly didn't. What that means for any given trade is up to you.

Hidden Liquidity Profile [Alpha Extract]A sophisticated liquidity-mapping and support/resistance profiling framework that analyzes historical candle structure, volume, wick behaviour, and price distribution to identify hidden supply and demand zones across the chart. Hidden Liquidity Profile is designed to reveal where meaningful liquidity may be concentrated by separating sell-side and buy-side pressure into price bins, then projecting those zones forward as heat boxes, horizon lines, key price tags, and a real-time support/resistance dashboard.
Rather than relying on simple pivot highs and lows, the system evaluates how volume interacted with candle ranges, upper wicks, lower wicks, candle bodies, and recency weighting. This creates a dynamic liquidity profile that highlights where price may encounter resistance, support, absorption, or reaction zones.
🔶 Hidden Liquidity Profiling Engine
Builds separate supply and demand profiles across the selected lookback range. The system divides price into configurable bins, then distributes liquidity strength into those bins based on volume, candle range, wick size, body size, and age decay.
energy = vol * rng * decay
sellStrength = energy * (upWick * wickWeight + body * bodyWeight * sellBias)
buyStrength = energy * (dnWick * wickWeight + body * bodyWeight * buyBias)
This allows the indicator to estimate where sell liquidity and buy liquidity are most likely concentrated rather than only marking obvious visible highs and lows.
🔶 Supply & Demand Separation
The profile separates upper-wick and lower-wick pressure into two distinct liquidity maps.
Upper wick activity contributes to the supply profile, helping identify areas where sellers may have previously absorbed price movement. Lower wick activity contributes to the demand profile, helping identify zones where buyers may have previously defended price.
This separation gives traders a clearer view of whether nearby levels are more likely to behave as resistance, support, or balanced liquidity.
🔶 Age-Weighted Liquidity Decay
Applies a recency decay model so newer candles have stronger influence than older candles. This keeps the profile focused on liquidity that is more relevant to the current market environment while still preserving broader historical context.
The Age Decay Power setting controls how aggressively older liquidity fades. Higher values emphasize recent price action more strongly, while lower values retain more historical structure.
🔶 Price Bin Distribution System
Divides the analyzed price range into configurable price bins and assigns liquidity strength into each level. The Price Bins setting controls the resolution of the profile.
More bins create a finer, more detailed liquidity map. Fewer bins create a smoother, broader view of major supply and demand areas.
🔶 Distribution Radius Smoothing
Uses a configurable distribution radius to spread liquidity strength around nearby bins. This prevents the profile from becoming too fragmented and helps form smoother liquidity clusters.
This is especially useful on volatile assets where important liquidity zones often form across small ranges rather than at one exact tick.
🔶 Liquidity Heat Box Visualization
Displays supply and demand as horizontal heat boxes projected to the right side of the chart.
Supply liquidity is shown on the sell side using the selected sell color, while demand liquidity is shown on the buy side using the selected buy color. Wider and brighter boxes represent stronger normalized liquidity at that price level.
This creates a visual depth-style map that helps traders quickly identify where meaningful liquidity may be stacked above and below current price.
🔶 Forward Horizon Lines
Projects stronger liquidity levels forward using horizontal lines. These lines act as future reference zones where price may react, pause, reject, or accelerate through.
The Line Trigger setting controls how strong a liquidity level must be before it is projected. The Line Width Scale setting adjusts how visually dominant stronger levels appear.
🔶 Key Level Detection Framework
Identifies the strongest supply and demand levels from the profile and labels them directly on the chart.
The system can prioritize local peaks, helping avoid overcrowding and ensuring that selected levels represent distinct liquidity clusters rather than multiple nearby bins from the same zone.
This scoring model favors levels with strong dominant liquidity while still accounting for total combined activity.
🔶 Supply HVN & Demand HVN Labels
Marks high-volume liquidity nodes as Supply HVN or Demand HVN depending on which side of the profile dominates at that price.
Each label includes the level type, normalized strength percentage, and exact price. This allows traders to quickly identify the most important liquidity levels without manually reading the full heat map.
🔶 Nearest Support & Resistance Logic
Calculates the most relevant resistance above price and support below price using both liquidity strength and distance from current price.
Levels closer to current price receive more practical importance, while still needing enough liquidity strength to qualify. This helps the dashboard focus on actionable nearby zones instead of simply displaying the strongest level anywhere in the lookback range.
🔶 Aura Point Of Control
Identifies the strongest combined liquidity level across the profile. This Aura POC represents the price zone with the highest combined supply and demand activity.
The POC can act as a major reference point for balance, rotation, acceptance, rejection, or future retests.
🔶 Liquidity Pressure Balance
Compares total normalized demand against total normalized supply to estimate the broader pressure bias across the analyzed range.
When demand is meaningfully stronger, the dashboard shows a demand bias. When supply dominates, it shows a supply bias. When the two sides are close, the market is classified as balanced.
🔶 Real-Time S/R Dashboard
Includes a compact dashboard showing the most important liquidity information directly on the chart:
• Nearest resistance level
• Nearest support level
• Aura POC
• Supply, demand, or balanced pressure
• Active liquidity level count
• Current ticker reference
This gives traders a quick summary of where the strongest nearby reaction zones are and whether the broader liquidity profile is tilted toward supply or demand.
🔶 Customizable Visual Controls
Provides flexible display controls for heat boxes, horizon lines, key level tags, dotted key level lines, and the dashboard.
Traders can adjust the number of analyzed bars, price bin resolution, liquidity smoothing, projection distance, box width, line width, and trigger thresholds to match different assets and timeframes.
🔶 Clean Overlay Design
The full liquidity map is displayed directly on price without requiring a separate oscillator pane. Heat boxes appear to the right of the chart, while key levels and labels extend across the active lookback area.
This keeps the chart readable while still providing a detailed view of hidden supply and demand structure.
🔶 Why Choose Hidden Liquidity Profile ?
Hidden Liquidity Profile provides a more advanced way to identify potential support, resistance, and liquidity reaction zones by analyzing volume-weighted candle structure across the full price range. Instead of marking only visible swing highs and lows, it evaluates where supply and demand pressure may be concentrated based on wick behaviour, candle body participation, volume energy, and recency-weighted price distribution.
The heat boxes reveal liquidity density, the horizon lines project important levels forward, the HVN labels highlight the strongest zones, and the dashboard summarizes nearest support, resistance, POC, and pressure bias in real time.
Perfect for liquidity traders, support/resistance traders, intraday traders, swing traders, and market structure analysts who want a cleaner way to visualize hidden supply and demand zones directly on the chart. Индикатор
Volume Profile - AccurateCore Architecture
1. Lower-Timeframe Precision Engine Traditional volume profiles on TradingView can be inaccurate because they guess the volume distribution within a daily candle. This script actually pulls raw data from a lower Source TF (default 5-minute) using request.security_lower_tf and mathematically reconstructs the exact volume traded at every single price tick for the entire day.
2. The Histogram (The Profile itself) It divides the entire price range of the period into a set number of horizontal rows (default 24). It then sorts the lower timeframe volume into these rows, painting a histogram (horizontal bars) on the side of the chart.
Key Trading Features
1. Point of Control (POC) The script mathematically isolates the single row with the absolute highest traded volume for the period.
Action: It projects a solid red line across the chart at this exact price level. The POC acts as the ultimate "fair value" price where buyers and sellers agreed the most, making it a massive magnet for future price action and a strong support/resistance level.
2. Value Area (VA) It calculates the core range where the majority of the trading took place (default is 68% of all volume, representing one standard deviation).
Action: It plots the Value Area High (VAH) and Value Area Low (VAL) as blue lines, and dynamically fills the background between them. Trading outside the Value Area represents an imbalance, while trading inside it represents balance.
3. Advanced Node Detection (HVN & LVN) This is where the script shines. It doesn't just plot the profile; it uses an algorithm to scan the shape of the profile and identify specific structural anomalies:
HVN (High Volume Nodes): Peaks in the profile (other than the POC). The script automatically draws red dashed lines and boxes at these levels. They act as localized support/resistance ledges.
LVN (Low Volume Nodes): Valleys or "gaps" in the profile where price moved so fast that almost zero volume was traded.
LVN Areas: The script goes a step further and intelligently groups adjacent LVNs together to create an "LVN Area" box (default Lime Green). Because there is no historical volume here to stop the price, if price enters an LVN Area, it will usually slice right through it like a hot knife
through butter.
Visual Control
It uses Pine Script's array-based object management (array, array) to dynamically clean up and redraw the profile flawlessly on every tick. You have full control in the settings over where the profile draws (Left/Right), its width, the color of the Value area vs outside the Value area, and toggles for every single specific node. Индикатор
Visible Range Volume NodesVisible Range Volume Nodes is a visible-range volume profile indicator that shows how traded volume is distributed across price levels inside the currently visible chart area.
The script builds a horizontal volume profile from the candles visible on the chart. It divides the visible price range into rows and distributes each candle's volume across the price rows touched by that candle's high-low range. Rows with more accumulated volume are displayed wider. Rows with less accumulated volume are displayed narrower.
How volume is calculated
Each candle's volume is distributed proportionally across the price rows covered by that candle's high-low range. If a candle covers several rows, its volume is split between those rows based on the amount of price overlap.
Bullish and bearish volume are separated using candle direction:
* Candles closing above their open are counted as bullish volume;
* Candles closing below their open are counted as bearish volume;
* Neutral candles are split evenly.
Key Volume Areas
POC - Point of Control
POC is the price row with the highest volume inside the visible range. It marks the largest volume concentration in the selected chart area.
VAH - Value Area High
VAH is the upper boundary of the value area.
VAL - Value Area Low
VAL is the lower boundary of the value area.
The value area starts from the POC and expands through the highest-volume neighboring rows until the selected percentage of total visible-range volume is included. By default, this is commonly used as a 70% value area, but the percentage can be changed in the settings.
HVN - High Volume Node
HVN zones are high-volume areas detected from local peaks in the smoothed volume profile. These zones show where volume was concentrated compared with nearby price levels.
LVN - Low Volume Node
LVN zones are low-volume areas detected from local valleys in the smoothed volume profile. These zones show where volume was thinner compared with nearby price levels.
How to use it
The profile can help users compare current price action with previously traded volume areas inside the selected visible range:
* POC shows the main high-volume reference area of the visible range;
* VAH and VAL show the upper and lower limits of the main value area;
* HVN zones show areas where price previously spent more volume;
* LVN zones show areas where volume was thinner relative to nearby price levels;
* The histogram shows the full volume distribution across the selected price range.
A trader can use these areas as context when analyzing price location. For example, price trading near POC is trading near the main volume concentration of the visible range. Price trading near VAH or VAL is trading near the edge of the calculated value area. HVN and LVN zones can be used to compare current price behavior with areas of stronger or weaker previous volume participation.
These levels should be treated as structural references only. They are not automatic entries, exits, support, resistance, targets, or invalidation levels.
Main settings
* Profile Rows controls how many price rows are used to build the volume profile. More rows create a more detailed profile. Fewer rows create a smoother, broader profile;
* Value Area % controls how much of the visible-range volume is included inside the value area;
* Histogram Direction controls whether the profile is displayed to the left or right side of the visible chart area;
* Profile Distance controls the spacing between the visible candles and the profile panel;
* The script also includes settings for showing or hiding POC, VAH/VAL, HVN, LVN, labels, prices in labels, line style, line width, label size, and colors.
Limitations
*This indicator does not generate buy or sell signals;
*It does not predict future price direction;
*It does not define guaranteed support or resistance;
*It does not use exact bid/ask volume;
*It does not use footprint, delta, or order book data.
The displayed structure depends on the selected visible range, symbol, exchange, timeframe, and available volume data.
Because the profile is based on the currently visible chart range, moving or zooming the chart can change the calculated POC, value area, HVN zones, and LVN zones.

AGT LevelsAGT Levels is a custom volume-profile-based support and resistance tool designed to highlight key High Volume Nodes and Low Volume Nodes directly on your chart.
Instead of using standard horizontal levels, this indicator builds a full right-side volume profile from the same data used to calculate the levels. The profile is plotted to the right of price and faces back toward the chart, making it easier to see where volume has built up and where price may react.
The main idea is simple:
High Volume Nodes can act as areas where price accepts value, consolidates, or reacts strongly.
Low Volume Nodes can act as rejection zones, thin liquidity areas, or fast-move regions where price may move quickly through or reject from.
The indicator includes:
• Full right-side volume profile
• Up/down volume split inside the profile
• HVN and LVN level detection
• Major and minor level zones
• Adjustable sensitivity settings
• Adjustable profile offset
• Level zones extending from the volume profile
• Optional boxes, midlines, or both
• Alerts for level touches and rejections
The Sensitivity setting controls both the volume profile resolution and the level detection logic:
Conservative gives cleaner, broader levels.
Balanced gives a good all-round view.
Aggressive gives more granular levels and a more detailed profile.
This tool is designed to help traders identify important volume-based reaction zones, rather than relying only on traditional highs/lows or manually drawn support and resistance.
Best used together with your own market structure, session bias, VWAP, orderflow, or liquidity-based strategy.
This script does not predict future price movement. It is intended for technical analysis, backtesting, and educational use only.

LVN/HVN Auto Detection [PhenLabs]📊 PhenLabs - LVN/HVN Auto Detection
Version: PineScript™ v6
📌 Description
The PhenLabs LVN/HVN Auto Detection indicator is an advanced volume profile analysis tool that automatically identifies Low Volume Nodes (LVN) and High Volume Nodes (HVN) across multiple trading sessions. This sophisticated indicator analyzes volume distribution patterns to pinpoint critical support and resistance levels where price is likely to react, providing traders with high-probability zones for entries, exits, and risk management.
Unlike traditional volume indicators that only show current activity, this tool builds comprehensive volume profiles from historical sessions and intelligently filters the most significant levels. It combines real-time volume analysis with dynamic level detection, offering both visual bubbles for immediate volume activity and persistent horizontal lines that act as ongoing support/resistance references.

📖 Usage Guidelines
Volume Thresholds
LVN Threshold
○ Default: 20.0%
○ Range: 5.0-35.0%
○ Description: Price levels with volume below this percentage are marked as LVNs. Lower values create fewer, more significant levels. Typical range 15-25% works for most instruments.
HVN Threshold
○ Default: 80.0%
○ Range: 65.0-95.0%
○ Description: Price levels with volume above this percentage are marked as HVNs. Higher values create fewer, stronger levels. Range 75-85% is optimal for most trading.
Display Controls
Volume Threshold
○ Default: 1.5
○ Range: 0.5+
○ Description: Multiplier for volume significance (High=2+threshold, Medium=1+threshold, Low=0+threshold). Higher values require more volume for signals.
✅ Best Use Cases
Swing Trading : Identify key levels for position entries and exits over multiple days
Scalping : Use bubbles for immediate volume activity confirmation at critical levels
Risk Management : Place stops beyond LVN levels where price moves quickly
Breakout Trading : Monitor HVN levels for potential breakout or rejection scenarios
Multi-Timeframe Analysis : Combine with higher timeframe levels for confluence
⚠️ Limitations
Timeframe Sensitivity : Lower timeframes may produce too many levels; higher timeframes recommended for cleaner signals
Volume Data Dependency : Accuracy depends on reliable volume data from your data provider
Historical Analysis : Uses past volume data which may not predict future price behavior
Performance Impact : High number of active lines may affect chart performance on slower devices
💡 What Makes This Unique
Automated Session Analysis : No manual drawing required - automatically analyzes multiple sessions
Intelligent Filtering : Advanced separation logic prevents overlapping and conflicting signals
Adaptive Processing : Adjusts to different timeframes automatically for optimal level detection
Dual Visualization System : Combines persistent lines with real-time activity indicators
🔬 How It Works
1. Volume Profile Construction :
Analyzes the last 5 trading sessions with dynamic session length based on timeframe
Divides each session’s price range into 20 equal levels for volume distribution analysis
2. Level Classification :
Calculates volume percentage at each price level relative to session maximum
Identifies LVN levels below threshold and HVN levels above threshold
3. Signal Generation :
Creates bubbles when volume activity exceeds thresholds at identified levels
Draws horizontal lines that persist until price crosses through them
💡 Note : For optimal results, increase your chart timeframe if you see too many levels. The indicator performs best on 15-minute and higher timeframes where volume patterns are more meaningful and less noisy. Индикатор
Volume Profile [TFO]This indicator generates Volume Profiles from which to display insights about recent Volume Points of Control and High Volume Nodes. Volume Profile is a way to view trading volume by the price where trades have occurred, rather than the time when they occur (as seen by traditional Volume indicators).
By selecting a Resolution Timeframe (1m in this example), we can aggregate the volume at different prices to build a Volume Profile for a specified Profile Timeframe (1D in this example). In this indicator, we make the simple assumption that a given candle's volume is distributed evenly across all points. Realistically, this is seldom the case, but it gives us a starting point to easily estimate the volume at a given price, in turn helping us to build our profiles in a trivial way.
If we do this for all Resolution Timeframe candles within a Profile Timeframe (all 1m candles in a single 1D candle, in this example), then we can successfully aggregate this data and build a full Volume Profile. And thankfully, Pine Script's new polyline feature ultimately allow us to keep more Volume Profiles on our charts. Before polylines, we would have to consider using lines or boxes to represent the individual levels within a given profile, and each script currently has a cap of 500 lines and boxes, respectively. However, one single polyline can be used to draw the complex shape of an entire profile, and we may show up to 100 polylines in a given script. This helps us keep a lot more data on our charts!
Compared to TradingView's Session Volume Profile indicator (blue/yellow), we can see that our indicator (grey) is nearly identical, which verifies that our assumption of a uniform volume distribution is enough to roughly estimate a given Volume Profile. Note in this example the Row Size was set to 200, meaning that 200 levels are used to approximate profiles from each session's high to its low.
Show VPOC will show the volume point of control of each profile, which represents the price level where the largest amount of volume was traded for a given profile. This is shown with the red lines in the following chart.
Extend Last N VPOCs will look for the most recent, user-defined number of VPOCs (not including the current session's VPOC that's still developing) and extend them to the right of the chart as points of reference. The Show Labels Above option will annotate each VPOC with its respective date above a specified timeframe. This way, if one was using Volume Profiles on intraday timeframes, there wouldn't need to be several date strings all showing the same day.
Show Previous HVNs will show high volume nodes from the previous session. The HVN Strength setting is similar to a "pivot strength" that I use in a lot of my scripts - essentially, HVNs are validated by treating them as local highs. With a HVN Strength of 10 for example, if a given level contains more volume than the 10 levels above and below it, then it is validated as a HVN.
For a cleaner look and feel, HVNs can instead be shown as levels (lines) instead of areas (boxes). With levels enabled, solid lines denote the previous session's VPOC, and dotted lines represent all other HVNs. With areas enabled instead, the tops and bottoms will extend above/below the HVN level until a point with greater volume is discovered (marking the "end" of the node).
This indicator can be computationally intensive and may crash from taking too long to execute. In these cases, it's best to disable unused features, decrease the number of Rows, and/or simply reload the chart until it populates. Индикатор
