EVA Ai + POC, Liquidity & Smart Money

## Overview

**EVA Ai+ Volume Profile — POC, Value Area & Liquidity** is a market-structure and volume-distribution indicator designed to analyze where trading activity is concentrated across price.

Its primary purpose is to combine price-based Volume Profile information with confirmed liquidity structure in one analytical framework.

The script calculates a horizontal volume distribution, Point of Control (POC), Value Area, High-Volume Nodes (HVN), Low-Volume Nodes (LVN), directional volume estimates, and confirmed buy-side/sell-side liquidity pools.

These components are not intended to function as independent entry signals. They are combined to help answer a specific analytical question:

**Where is price currently being accepted, where is participation relatively low, and where does confirmed unswept liquidity remain in relation to that auction structure?**

The indicator does **not** generate automatic LONG or SHORT recommendations and does not execute trades.

---

## Purpose of the combined architecture

Volume Profile and liquidity analysis describe different aspects of market behavior.

Volume Profile measures how the available volume data is distributed across price.

Liquidity structure identifies confirmed areas around comparable swing highs and lows that have not yet been fully cleared according to the script's rules.

EVA combines these concepts because either one viewed in isolation can omit relevant context.

For example:

* POC and Value Area describe the center and boundaries of accepted value;
* HVNs identify local concentrations of calculated participation;
* LVNs identify comparatively low-volume regions;
* directional volume provides context about the composition of the calculated profile;
* confirmed BSL/SSL pools identify unresolved liquidity structures;
* distance and quality calculations place those structures in relation to current volatility and price.

The intended result is a single auction map showing **value, participation, low-volume structure, and confirmed liquidity context together**.

This interaction is the principal reason these components are included in one script.

## Volume Profile

The script distributes the available volume across horizontal price rows within the active calculation range.

The profile is intended to show where the selected market spent comparatively more or less trading activity.

### Point of Control — POC

POC is the price row containing the largest amount of calculated profile volume.

It represents the highest-volume row of the current profile calculation.

It should not be interpreted as an automatic support, resistance, entry, or reversal signal.

### Value Area

The Value Area contains the configured percentage of calculated profile volume surrounding the profile's primary volume concentration.

A commonly used setting is 70%.

The script displays:

* **VAH** — Value Area High;
* **VAL** — Value Area Low.

Price inside the Value Area indicates that it is trading within the profile's calculated value region.

Price above VAH or below VAL indicates that it is outside that region, but this condition alone does not imply continuation or reversal.

---

## HVN and LVN structure

### High-Volume Nodes — HVN

HVNs are local concentrations within the calculated profile where neighboring rows contain comparatively high volume.

They can be used to identify areas of previous acceptance or repeated participation.

Possible market behavior around an HVN can include rotation, consolidation, retesting, support/resistance behavior, or no meaningful reaction at all.

The script does not assume that an HVN must hold.

### Low-Volume Nodes — LVN

LVNs are local low-volume regions between areas of greater calculated participation.

They can highlight portions of the profile where historical acceptance was comparatively limited.

Price may sometimes traverse these areas more quickly, but an LVN does not guarantee acceleration or determine direction.

HVN and LVN structures remain components of the calculated profile and can change when the active profile range changes.

---

## Directional volume context

When lower-timeframe data is available, the script classifies lower-timeframe volume according to candle direction and aggregates that information into the profile.

The resulting values are displayed as:

* Up Volume;
* Down Volume;
* Delta.

**Delta in this indicator is the difference between the script's classified Up Volume and Down Volume.**

It is important to distinguish this from exchange-level bid/ask order-flow delta.

Pine Script does not provide the script with a complete historical exchange order book or universal historical bid/ask footprint data.

Therefore, EVA does not claim to reconstruct those datasets.

Directional volume is an approximation derived from the available lower-timeframe OHLCV data.

---

## BSL and SSL liquidity structure

The liquidity component identifies confirmed structures around comparable pivot highs and lows.

### BSL — Buy-Side Liquidity

BSL structures are created above qualifying comparable swing highs.

### SSL — Sell-Side Liquidity

SSL structures are created below qualifying comparable swing lows.

The script does not label every swing high or swing low as liquidity.

A liquidity structure requires multiple confirmed pivot observations that satisfy the script's similarity, spacing, volatility, and quality conditions.

This filtering is intended to reduce the number of insignificant structures displayed on the chart.

Liquidity terminology in this script represents a technical model based on price structure. It does not imply direct observation of hidden orders or stop orders in an exchange order book.

---

## Liquidity Quality

Each qualifying liquidity structure receives a quality value based on several measurable properties of the detected structure.

Depending on the active configuration, these properties include factors such as:

* relative volume;
* rejection characteristics;
* spacing between qualifying pivots;
* volatility-adjusted geometry.

The quality value is used for filtering and ranking detected structures.

It is a relative analytical score created by this script. It is **not a probability of a profitable trade or a prediction that a liquidity level will be reached or swept**.

---

## Liquidity states

Detected pools can move through several states.

### FRESH

The qualifying structure has been confirmed and has not yet met the script's test or sweep conditions.

### TESTED

Price has interacted with the structure according to the configured testing rules without completing the full sweep condition.

### OFF

The structure remains internally valid but falls outside the configured volatility-adjusted working radius and is therefore not displayed as an active nearby structure.

### SWEPT

Price has crossed the structure's defined far boundary.

Once this condition is confirmed, the corresponding active pool drawings are removed.

The state system prevents historical liquidity structures from remaining visually active after the script considers them resolved.

---

## Nearest structural references

The dashboard identifies nearby calculated structures such as:

* BSL;
* SSL;
* HVN;
* LVN.

Distances can be normalized using ATR so that the displayed distance is comparable across instruments with different nominal prices and volatility.

These values describe **location**, not trade expectancy.

A nearby BSL, SSL, HVN, or LVN should not be interpreted as a recommendation to enter a position.

---

## Profile modes

The script supports several ways to define the profile range.

### Visible Range

The profile is calculated from the chart region used by the script's visible-range logic.

Changing the visible chart area can therefore change the profile.

This behavior is intentional.

A Visible Range profile is dynamic and should not be interpreted as an immutable historical signal.

### Session

The profile is calculated using the selected session boundaries.

This mode can be used to examine session-specific POC, Value Area, and volume distribution.

### Fixed Range

The profile is calculated between user-defined time boundaries.

This mode can be used to inspect a specific impulse, consolidation, expansion, or other manually selected market segment.

---

## Adaptive configuration

The optional adaptive mode adjusts selected calculation parameters according to chart conditions.

Depending on configuration, this can include:

* lower-timeframe selection;
* profile row density;
* HVN/LVN sensitivity;
* pivot sensitivity;
* liquidity-zone width;
* minimum liquidity-quality threshold;
* volatility-adjusted display radius.

The purpose of this mode is to maintain usable analytical resolution across different chart timeframes and price scales.

Adaptive configuration does not optimize for future profitability and does not predict future market direction.

Users can disable adaptive behavior and use manual settings where required.

---

## Dashboard

The dashboard summarizes the current calculated state of the indicator.

Depending on the selected configuration, it can display:

### Auction

The location of current price relative to VAH, VAL, and the calculated Value Area.

### Range / Source

The active profile mode and the data source currently used by the calculation.

### Rows × Step

The effective number of price rows and the price increment represented by each row.

### Up / Down / Delta

The directional volume classification generated from the available data.

### POC / Distance

The current POC and price distance from it.

### Nearest BSL / SSL

The nearest qualifying liquidity structure together with distance, quality, and state.

### Nearest HVN / LVN

The nearest calculated high-volume and low-volume structures.

### Structure

A descriptive classification of the current volume distribution.

### Status

Information concerning the current calculation mode and available data.

The dashboard summarizes calculated information; it does not produce trading instructions.

---

## How to interpret the map

### Price inside Value Area

Price inside VAH and VAL is trading within the profile's calculated value region.

POC and HVNs can help locate concentrations of historical participation.

This does not necessarily imply a ranging market or predict that price will remain inside the Value Area.

### Price above VAH

Price above VAH is outside the upper boundary of the calculated Value Area.

Whether the move continues or returns into value depends on subsequent market behavior.

VAH alone is not a breakout confirmation.

### Price below VAL

Price below VAL is outside the lower boundary of the calculated Value Area.

VAL alone does not confirm bearish continuation.

### Interaction with an LVN

An LVN identifies a region of comparatively low calculated participation.

It can be used to observe how price behaves when entering a low-volume region, but it does not guarantee rapid movement through that area.

### Interaction with liquidity

When price reaches a BSL or SSL structure, users can observe whether the level remains active, becomes tested, or satisfies the script's sweep condition.

A sweep is a structural event only.

**A liquidity sweep does not by itself imply a reversal or continuation.**

---

## Data handling and confirmation

Where available, lower-timeframe OHLCV data is used to improve the allocation of volume within higher-timeframe chart candles.

When the requested lower-timeframe sample is unavailable or insufficient for the selected calculation, the script can use its documented fallback calculation instead of presenting an incomplete lower-timeframe profile as if it were complete.

Liquidity structures are based on confirmed pivot events.

Because a pivot requires subsequent bars for confirmation, a newly confirmed liquidity structure can appear later than the historical bar on which the pivot itself occurred.

The script does not interpret this confirmation delay as advance knowledge.

Developing profiles can change as additional data arrives.

Visible Range profiles can also change when the chart viewport changes.

These behaviors are inherent to dynamic profile calculations and should not be interpreted as historical trade signals being rewritten.

---

## Originality and design rationale

The script uses established analytical concepts such as Volume Profile, POC, Value Area, pivots, ATR normalization, and liquidity terminology.

It does not claim that those individual concepts are proprietary.

The distinctive functionality of this implementation is their integration into a unified state-based analytical system.

Instead of independently displaying several unrelated indicators, EVA:

1. builds a common price-row volume model;
2. derives POC and Value Area from that same distribution;
3. identifies local HVN/LVN structure within the profile;
4. estimates directional volume from lower-timeframe data where available;
5. independently confirms comparable pivot structures;
6. applies volatility-, geometry-, and participation-based filtering to those structures;
7. maintains lifecycle states for active liquidity pools;
8. relates nearby volume and liquidity structures to current price using a common dashboard and normalized distance model;
9. provides explicit fallback behavior when detailed source data is unavailable.

The purpose of the integration is to provide one coherent representation of **auction value, relative participation, low-volume structure, and unresolved price-based liquidity** rather than a collection of independent signals.

---

## Why the source code is protected

The source code is protected to preserve the implementation of the script's integrated profile construction, adaptive parameter logic, node-classification methods, liquidity-quality filtering, state transitions, data-fallback handling, and visualization architecture.

Closed-source visibility is not intended to prevent users from understanding the indicator's behavior.

This description therefore documents the script's purpose, inputs, main calculations, interpretation, data limitations, and expected dynamic behavior without exposing implementation-specific formulas and thresholds.

---

## Important limitations

Users should understand the following limitations before using the indicator:

* The script only has access to data supplied to Pine Script by TradingView and the active symbol's data provider.
* Volume characteristics differ between markets and symbols.
* On some Forex instruments, the available volume can represent tick volume rather than centralized exchange volume.
* The script does not have access to a complete historical exchange order book.
* It does not know the location of actual individual traders' stop orders.
* BSL and SSL are price-structure models, not observations of hidden orders.
* Directional volume is derived from available candle data and is not equivalent to true exchange bid/ask footprint delta.
* Confirmed pivots necessarily introduce confirmation delay.
* Visible Range calculations can change when the chart viewport changes.
* Developing profiles can change as new bars or intrabars become available.
* HVNs, LVNs, POC, VAH, VAL, BSL, and SSL do not predict future price behavior.
* No individual component should be interpreted as a guaranteed support, resistance, breakout, reversal, entry, or target.
* Different symbols, sessions, timeframes, and data feeds can produce materially different profile structures.

---

## Intended use

EVA is intended as a **market-reading and contextual-analysis tool**.

A typical workflow is:

1. identify the current Value Area and POC;
2. inspect the shape of the volume distribution;
3. locate nearby HVN and LVN structures;
4. identify confirmed active BSL and SSL structures;
5. compare those structures with current price and volatility;
6. observe subsequent price and volume behavior;
7. perform an independent trade and risk assessment.

The indicator deliberately does not convert this information into automatic LONG or SHORT instructions.

## Risk disclosure

This script is an analytical indicator and does not execute orders.

It does not provide financial advice, guarantee trading outcomes, or predict future market behavior.

Historical structures and previous market reactions do not establish how price will behave in the future.

Users remain responsible for independent analysis, position sizing, execution decisions, and risk management.
