37 083
A volume-based multi-block analysis system designed for educational purposes. This indicator helps traders understand their current market situation through aggregated block analysis, volumetric calculations, trend detection, and an AI-style narrative engine.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
DESIGN PHILOSOPHY: CLEAN CHART, RICH DASHBOARD
Traditional indicators often clutter charts with dozens of support/resistance lines, making it difficult to see price action clearly. This indicator takes a different approach:
The Chart:
Displays only the most meaningful, nearest levels (1 up, 1 down) that have not been consumed by price. This keeps your chart clean and focused on what matters right now.
The Dashboard:
Contains all detailed metrics, calculations, and analysis. Instead of drawing 20 lines on your chart, you get comprehensive data in an organized table format.
Why this approach?
• A clean chart allows you to see price action without visual noise
• Fewer but more meaningful levels help focus attention on immediate reference points
• The dashboard provides depth without sacrificing chart clarity
• Beginners can learn chart reading with an uncluttered view while accessing detailed analysis when needed
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. BLOCK SEGMENTATION
What it does:
Divides the analysis window into fixed-size blocks. Each block contains multiple bars that are analyzed as a single unit.
Why:
Individual bars contain noise. A single red candle in an uptrend might cause unnecessary concern, but when you view 5-10 bars as one block, the overall direction becomes clear. Block segmentation filters out bar-to-bar noise and reveals the underlying structure.
Benefit:
• Clearer view of market structure at a higher aggregation level
• Enables comparison between time periods (Block 1 vs Block 2 vs Block 3)
• Creates the foundation for composite candles and trend detection
• Reduces emotional reaction to single-bar movements
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
2. COMPOSITE CANDLES (FRACTAL CONCEPT)
What it does:
Each block generates a "ghost candle" representing aggregated OHLC:
• Open: First bar's open in the block
• High: Highest high across all bars in the block
• Low: Lowest low across all bars in the block
• Close: Last bar's close in the block
Why:
This is essentially a FRACTAL view of the market. The same candlestick patterns that appear on a daily chart also appear on hourly charts, and on 5-minute charts. By aggregating bars into composite candles, you create a synthetic higher timeframe view without changing your actual timeframe.
Benefit:
• See higher timeframe patterns while staying on your preferred timeframe
• Identify block-level candlestick patterns (Doji, Hammer, Marubozu, Engulfing, etc.)
• Compare composite candle relationships: Does Block 1 engulf Block 2? Is Block 1 an inside bar relative to Block 2?
• Recognize patterns that individual bars obscure due to noise
Fractal Nature:
A hammer pattern means the same thing whether it appears on a 1-minute chart or a weekly chart: price tested lower levels and was rejected. Composite candles let you see these patterns at your chosen aggregation level, providing a multi-scale view of market behavior.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
3. VOLUME ENGINE
What it does:
This indicator is 100% VOLUME-BASED. It separates total volume into buying volume and selling volume using two methods:
Method 1 - Geometric (Approximation):
• Buy Volume = Total Volume × ((Close - Low) / Range)
• Sell Volume = Total Volume × ((High - Close) / Range)
Method 2 - Intrabar LTF (Precise):
Uses actual tick-level or lower timeframe data to determine real buy/sell distribution.
Why:
Raw volume tells you HOW MUCH was traded, but not WHO was aggressive. A large volume bar could mean heavy buying, heavy selling, or both. By separating buy and sell volume, you can identify which side is driving the market.
Benefit:
• Identify whether buyers or sellers are more aggressive
• Detect when volume contradicts price direction (divergence)
• Measure accumulation (buying into weakness) vs distribution (selling into strength)
• Quantify the delta (buy minus sell) to see net pressure
Why Delta Matters:
If price is rising but delta is negative, sellers are actually more aggressive despite the price increase. This divergence often precedes reversals because the price movement lacks volume confirmation.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
4. PIN ANALYSIS (WICK MEASUREMENT)
What it does:
Calculates average upper pin (wick) and lower pin sizes for each block, then tracks how these change across consecutive blocks.
Why:
Upper pins represent price levels that were tested but rejected by sellers. Lower pins represent price levels that were tested but rejected by buyers. The size and direction of pins reveal rejection strength at specific price zones.
Benefit:
• Large upper pins = strong selling pressure at higher levels
• Large lower pins = strong buying support at lower levels
• Increasing upper pins across blocks = intensifying selling pressure
• Decreasing lower pins across blocks = weakening buying support
Why Track Pin Changes:
Pin behavior often changes before price direction changes. If lower pins are shrinking while price is still rising, the buying support that was defending dips is weakening. This is observable data, not prediction.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
5. TREND CHANNEL DETECTION
What it does:
Identifies trend direction using block-level price structure:
• UPTREND: Block highs are higher than previous block highs, AND block lows are higher than previous block lows (HH/HL pattern)
• DOWNTREND: Block highs are lower than previous block highs, AND block lows are lower than previous block lows (LH/LL pattern)
• RANGE: No consistent directional pattern
Once detected, the system draws upper and lower channel boundaries by connecting extreme points within each trend segment.
Why:
HH/HL and LH/LL are the classical definitions of trend. By applying this logic to composite candles (blocks) rather than individual bars, the trend detection becomes more stable and less prone to whipsaws from single-bar noise.
Benefit:
• Clear visual boundaries showing the current trend channel
• Upper channel line = dynamic resistance based on actual price structure
• Lower channel line = dynamic support based on actual price structure
• Channel angle indicates trend strength (steeper = stronger)
• Channel width indicates volatility
Why Lock Trend States:
Once a block's trend classification is determined, it locks and does not change on subsequent recalculations. Without locking, the same block could flip between UP and DOWN repeatedly, creating inconsistent analysis. Locking ensures stability.
Why Project Lines Forward:
Channel lines can be projected into the future to show where support/resistance would be if the current trend continues at the same angle. This is not a prediction; it is a visual reference showing the trend's trajectory.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
6. CORE LEVELS: POC, MAX BUY, MAX SELL
What it does:
Identifies key price levels within each block based on volume data:
POC (Point of Control):
The price level where the highest total volume occurred within the block.
MAX BUY Level:
The bar with the highest buying volume. The HIGH of this bar marks the level.
MAX SELL Level:
The bar with the highest selling volume. The LOW of this bar marks the level.
MIN BUY/SELL Levels:
Optional levels showing where minimum buy/sell volume occurred.
Why:
High volume at a specific price means many participants entered positions there. These participants have a vested interest in that price level. If price returns to that area, those same participants may act to defend their positions.
Benefit:
• POC acts as a volume-based magnet; price tends to revisit high-volume areas
• MAX BUY level shows where buyers committed most aggressively
• MAX SELL level shows where sellers committed most aggressively
• These levels are based on actual transaction data, not arbitrary calculations
Why Consumed Levels Disappear:
When price crosses through a level, that level has been "tested." Keeping consumed levels on the chart creates visual clutter and suggests they are still relevant when they may no longer be. Removing them keeps focus on levels that have not yet been tested.
Why Show Only Nearest Levels:
If you have 20 blocks, you could have 60+ potential levels (POC, MAX BUY, MAX SELL for each). Displaying all of them makes the chart unreadable. Showing only the nearest untested level above and below current price keeps the chart clean while providing immediate reference points.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
7. QUALITY SCORE AND TREND INTELLIGENCE
What it does:
Calculates a quality score (0-100) for the current trend based on multiple factors:
• Angle steepness (stronger trends have steeper angles)
• Delta consistency (does volume support the trend direction?)
• Volume momentum (is participation increasing or decreasing?)
• Body expansion (are candle bodies growing or shrinking?)
• Pin alignment (do pins support the trend direction?)
• Contradiction count (how many factors disagree?)
Why:
Not all trends are equal. A trend with consistent volume support, expanding bodies, and aligned pins is healthier than a trend with contradicting signals. The quality score quantifies this.
Benefit:
• HIGH quality (80+): Multiple factors confirm the trend
• MEDIUM quality (60-79): Some factors confirm, some neutral
• LOW quality (below 60): Multiple contradictions exist
• Strength rating based on channel angle: VERY STRONG, STRONG, MODERATE, WEAK
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
8. NARRATIVE ENGINE
What it does:
Generates a text-based market analysis by synthesizing all calculated data into readable sentences.
How it works:
1. Analyzes current candle: pattern type (Doji, Hammer, Marubozu, etc.), body/wick ratios, range vs ATR
2. Analyzes composite candle: Block 1 pattern and relationship to Block 2 (Engulfing, Inside, Outside)
3. Evaluates trend context: direction, duration, quality, transitions
4. Examines volume data: delta, dominance, momentum direction
5. Checks proximity to key levels: channel boundaries, POC, core levels
6. Identifies divergences: when price and volume directions contradict
7. Produces a coherent narrative describing the current situation
Why:
Numbers and charts require interpretation. The narrative engine translates calculated data into plain language, helping traders understand what the data means in context. This is especially valuable for beginners learning to read charts.
Benefit:
• Synthesizes multiple data points into a coherent story
• Explicitly flags divergences and contradictions
• Describes the current situation without making predictions
• Educational: shows how different factors relate to each other
What the Narrative Does NOT Do:
The narrative describes what IS, not what WILL BE. It does not predict future price movement. It reports the current candle pattern, the current trend state, the current volume situation, and the current proximity to levels.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
9. SMART DASHBOARD
What it does:
Displays all metrics in an organized table with multiple sections.
Sections:
• Volume Engine: Calculation method, data availability, current candle buy/sell/delta
• Trend Volumetrics: Aggregated buy/sell/delta across the current trend, trend type
• Pressure and Momentum: Average pins, pin change percentages, body expansion status
• Trend Channel Boundaries: Upper/lower levels with exact prices, distances, percentages
• Trend Intelligence: Quality score, confidence level, strength rating, volume momentum
Why:
All the detailed calculations need to live somewhere without cluttering the chart. The dashboard provides comprehensive data in a structured format.
Benefit:
• All metrics in one place
• Organized by category for easy reference
• Hover over any label to see a tooltip explaining that metric
• No need to draw dozens of lines on the chart
TIP: Hover over dashboard headers and labels to see tooltips explaining each metric.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
10. LANGUAGE SUPPORT
The indicator supports three languages:
• English
• Türkçe (Turkish)
• हिन्दी (Hindi)
Why only three languages?
Each additional language requires duplicate strings throughout the code, increasing memory usage and compilation time. To keep the script optimized and responsive, language options are limited to these three.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
11. DATA ACCURACY AND LIMITATIONS
This indicator is 100% VOLUME-BASED and requires Lower Timeframe (LTF) intrabar data for accurate calculations.
DATA ACCURACY LEVELS:
• 1T (Tick): Most accurate, real volume distribution per tick
• 1S (1 Second): Reasonably accurate approximation
• 15S (15 Seconds): Good approximation, longer historical data available
• 1M (1 Minute): Rough approximation, maximum historical data range
BACKTEST AND REPLAY LIMITATIONS:
• Replay mode results may differ from live trading due to data availability
• For longer backtest periods, use higher LTF settings (15S or 1M)
• Not all symbols/exchanges support tick-level data
• Crypto and Forex typically have better LTF data availability than stocks
A NOTE ON DATA ACCESS:
Higher TradingView plans provide access to more historical intrabar data, which directly impacts the accuracy of volume-based calculations. More precise volume data leads to more reliable calculations.

This update introduces significant improvements to the core calculation engine, visual accuracy, and multilingual support. Below is a detailed breakdown of every change and its benefit.


1. Yang-Zhang (2000) Volatility Estimator

The previous version used ATR (Average True Range) to normalize channel angles. While ATR is a common volatility proxy, it only captures intraday range and ignores overnight gaps and open-to-close dynamics.

This update replaces ATR normalization with the Yang-Zhang (2000) volatility estimator — a mathematically proven, unbiased estimator that combines three components: overnight return variance (close-to-open), open-to-close variance, and the Rogers-Satchell intraday component. The result is a per-bar volatility measure in price units that is the most statistically efficient among all known OHLC-based estimators.

Practical benefit: Channel angles are now normalized against a more accurate and complete volatility measure, making the angle readings more reliable and consistent.


2. Volatility-Normalized Channel Angles

Previously, channel angles were calculated using an arbitrary scaling factor (multiplying by 10) against ATR. This produced angle values that changed meaning depending on the instrument's price level and the timeframe being viewed.

The new calculation uses the formula: expected move = σ × √T (Yang-Zhang volatility multiplied by the square root of the bar span). The price change is then divided by this expected move before computing the arctangent.

Practical benefit: A 45° angle now represents exactly one standard deviation move per √T — a scientifically meaningful measurement. Angles are now directly comparable across different instruments (e.g., BTC vs. AAPL) and across different timeframes (e.g., 1H vs. Daily) without any recalibration.

This same normalization is also applied to the individual upper and lower channel line angles displayed in the chart labels, ensuring all angle readings throughout the indicator are consistent and meaningful.


3. True Volume Profile POC (Bin Profile Engine)

The previous version determined the Point of Control (POC) by simply finding the single bar with the highest total volume within each block and using that bar's average price (hlc3). While simple, this method can miss the actual high-volume price zone when volume is distributed across multiple bars at similar price levels.

This update adds a true Volume Profile approach: each block's price range is divided into a configurable number of equal bins (default: 25). Each bar's volume is then distributed proportionally across the bins that its price range overlaps. The bin with the highest accumulated volume is selected as the POC, and its midpoint price is used.

Two new inputs are provided:
— "POC: Volume Profile Bins (All Plans)" — enables or disables the bin-based POC (default: ON)
— "POC Bin Resolution" — sets the number of bins from 10 to 100

Practical benefit: Significantly more accurate POC identification that reflects the actual high-volume price zone across all bars in the block, not just the single loudest bar. This feature works on all TradingView plans (Free, Plus, Premium, Ultimate) without requiring any special subscription.

When this feature is turned off, the original single-bar method is used as a fallback.


4. Continuous Quality Score Graduation

The previous quality scoring system used binary thresholds: for example, a channel angle of 34° scored zero points, while 36° scored the full 15 points — a single degree of difference caused a 15-point jump. This created dead zones where meaningful improvements in trend quality were not reflected in the score.

The updated scoring uses smooth, continuous scales for every component:
— Angle strength: linear interpolation from the Range Angle Threshold up to 45° (0 to 15 points)
— Delta consistency: proportional to the fraction of adjacent block pairs with matching delta sign (0 to 10 points)
— Volume momentum: linear scale from 0% to 50% growth (0 to 10 points)
— Body expansion: linear scale from 0% to 50% growth (0 to 10 points)
— Pin alignment: based on the dominance ratio of the directionally correct pin (0 to 8 points)

Practical benefit: Every incremental improvement in trend conditions is now reflected proportionally in the quality score. No more sudden jumps or dead zones. The score provides a smoother and more accurate representation of actual trend health.


5. Arabic Language Support

In response to requests from our valued Arabic-speaking audience, full Arabic language support has been added to the indicator. Arabic is now available as a fourth language option alongside English, Turkish, and Hindi.

Every text element in the indicator — including dashboard headers, data labels, tooltips, narrative analysis, candle pattern names, trend classifications, disclaimer text, and all connecting phrases — has been translated into Arabic.

Additionally, proper right-to-left (RTL) text alignment has been implemented. When Arabic is selected, dashboard cells and narrative text automatically align to the right, ensuring natural and comfortable reading for Arabic users.


6. Dashboard Capacity Increased

The dashboard table row count has been increased from 40 to 50 rows.

Practical benefit: Provides sufficient space for narrative text and the 3-line disclaimer across all supported languages, including Arabic which may produce longer text strings. Prevents content from being cut off in detailed analysis scenarios.


7. Disclaimer Row Reservation Corrected

The previous version reserved only 1 row for the educational disclaimer when calculating available narrative space, despite the disclaimer actually occupying 3 rows. This could cause the disclaimer to overlap with narrative content or be partially hidden.

The updated version correctly reserves 3 rows when the disclaimer is enabled.

Practical benefit: The disclaimer and narrative text no longer interfere with each other. All content displays cleanly without overlap.

📐 Update: Global Text Size — From Fixed Presets to Full Numeric Control
What changed:
Previously, the Global Text Size setting offered only four fixed options: Tiny, Small, Normal, and Large. These mapped directly to TradingView's legacy size.tiny, size.small, size.normal, and size.large constants — with absolutely nothing in between. If Small was too small and Normal was too big, there was simply no solution.
What it is now:
The entire font size system has been replaced with a single numeric input ranging from 6pt to 50pt (default: 12pt). This uses the same typographic point system found in standard text editors — you type a number, you get exactly that size. This applies uniformly to every text element on the chart: group number labels, core level labels, trend channel boundary labels, and every cell in the Smart Dashboard.
Why this matters:
After further research, I discovered that Pine Script v6 had recently introduced native support for numeric point-based text sizing, replacing the old fixed-constant system entirely. This capability was already available when I previously responded that it wasn't possible — my knowledge on this specific addition simply wasn't up to date at that point. Once I identified it, I updated the indicator immediately to bring it in line with the latest v6 standard, giving you precise, granular control over readability that was not available in earlier versions.
Credit where it's due:
This improvement was directly inspired by feedback from shabbathai, who pointed out the gap between Small and Normal and asked if something in between would be possible. That comment stayed with me and pushed me to dig deeper into the v6 documentation — which is exactly where I found this feature waiting to be used. Without that nudge, this update would have been delayed much longer. Community feedback like this is what drives real development forward. Thank you, @shabbathai. 🙏
