Volumeprofiler — 指標和策略

VWAP / ORB / VP & POC This is an all-in-one technical analysis tool designed to give you a comprehensive view of the market on a single chart. It combines three powerful indicators—VWAP, Opening Range, and Volume Profile—to help you identify key price levels, understand intraday trends, and spot areas of high liquidity. What It Does The indicator plots three distinct components on your chart: Volume-Weighted Average Price (VWAP): A benchmark that shows the average price a security has traded at throughout the day, based on both price and volume. It's often used by institutional traders to gauge whether they are getting a good price. The script also plots standard deviation or percentage-based bands around the VWAP line, which can act as dynamic support and resistance. Opening Range Breakout (ORB): A tool that highlights the high and low of the initial trading period of a session (e.g., the first 15 minutes). The script draws lines for the opening price, range high, and range low for the rest of the session. It also colors the chart with zones to visually separate price action above, below, and within this critical opening range. Volume Profile (VP): A powerful study that shows trading activity over a set number of bars at specific price levels. Unlike traditional volume that is plotted over time, this is plotted on the price axis. It helps you instantly see where the most and least trading has occurred, identifying significant levels like the Point of Control (POC)—the single price with the most volume—and the Value Area (VA), where the majority of trading took place. How to Use It for Trading The real strength of this indicator comes from finding confluence, where two or more of its components signal the same key level. Identifying Support & Resistance: The POC, VWAP bands, Opening Range high/low, and session open price are all powerful levels to watch. When price approaches one of these levels, you can anticipate a potential reaction (a bounce or a breakout). Gauging Intraday Trend: A simple rule of thumb is to consider the intraday trend bullish when the price is trading above the VWAP and bearish when it is trading below the VWAP. Finding High-Value Zones: The Volume Profile’s Value Area (VA) shows you where the market has accepted a price. Trading within the VA is considered "fair value," while prices outside of it are "unfair." Reversals often happen when the price tries to re-enter the Value Area from the outside. Settings: Here’s a breakdown of all the settings you can change to customize the indicator to your liking. Volume Profile Settings: Number of Bars: How many of the most recent bars to use for the calculation. A higher number gives a broader profile. Row Size: The number of price levels (rows) in the profile. Higher numbers give a more detailed, granular view. Value Area Volume %: The percentage of total volume to include in the Value Area (standard is 70%). Horizontal Offset: Moves the Volume Profile further to the right to avoid overlapping with recent price action. Colors & Styles: Customize the colors for the POC line, Value Area, and the up/down volume bars. VWAP Settings: Anchor Period: Resets the VWAP calculation at the start of a new Session, Week, Month, Year, etc. You can even anchor it to corporate events like Earnings or Splits. Source: The price source used in the calculation (default is hlc3, the average of the high, low, and close). Bands Calculation Mode: Standard Deviation: The bands are based on statistical volatility. Percentage: The bands are a fixed percentage away from the VWAP line. Bands Multiplier: Sets the distance of the bands from the VWAP. You can enable and configure up to three sets of bands. ORB Settings (Opening Range) Opening Range Timeframe: The duration of the opening range (e.g., 15 for 15 minutes, 60 for the first hour). Market Session & Time Zone: Crucial for ensuring the range is calculated at the correct time for the asset you're trading. Line & Zone Styles: Full customization for the colors, thickness, and style (Solid, Dashed, Dotted) of the High, Low, and Opening Price lines, as well as the background colors for the zones above, below, and within the range.

Advanced Volume Profile Pro Delta + POC + VAH/VAL # Advanced Volume Profile Pro - Delta + POC + VAH/VAL Analysis System ## WHAT THIS SCRIPT DOES This script creates a comprehensive volume profile analysis system that combines traditional volume-at-price distribution with delta volume calculations, Point of Control (POC) identification, and Value Area (VAH/VAL) analysis. Unlike standard volume indicators that show only total volume over time, this script analyzes volume distribution across price levels and estimates buying vs selling pressure using multiple calculation methods to provide deeper market structure insights. ## WHY THIS COMBINATION IS ORIGINAL AND USEFUL **The Problem Solved:** Traditional volume indicators show when volume occurs but not where price finds acceptance or rejection. Standalone volume profiles lack directional bias information, while basic delta calculations don't provide structural context. Traders need to understand both volume distribution AND directional sentiment at key price levels. **The Solution:** This script implements an integrated approach that: - Maps volume distribution across price levels using configurable row density - Estimates delta (buying vs selling pressure) using three different methodologies - Identifies Point of Control (highest volume price level) for key support/resistance - Calculates Value Area boundaries where 70% of volume traded - Provides real-time alerts for key level interactions and volume imbalances **Unique Features:** 1. **Developing POC Visualization**: Real-time tracking of Point of Control migration throughout the session via blue dotted trail, revealing institutional accumulation/distribution patterns before they complete 2. **Multi-Method Delta Calculation**: Price Action-based, Bid/Ask estimation, and Cumulative methods for different market conditions 3. **Adaptive Timeframe System**: Auto-adjusts calculation parameters based on chart timeframe for optimal performance 4. **Flexible Profile Types**: N Bars Back (precise control), Days Back (calendar-based), and Session-based analysis modes 5. **Advanced Imbalance Detection**: Identifies and highlights significant buying/selling imbalances with configurable thresholds 6. **Comprehensive Alert System**: Monitors POC touches, Value Area entry/exit, and major volume imbalances ## HOW THE SCRIPT WORKS TECHNICALLY ### Core Volume Profile Methodology: **1. Price Level Distribution:** - Divides price range into user-defined rows (10-50 configurable) - Calculates row height: `(Highest Price - Lowest Price) / Number of Rows` - Distributes each bar's volume across price levels it touched proportionally **2. Delta Volume Calculation Methods:** **Price Action Method:** ``` Price Range = High - Low Buy Pressure = (Close - Low) / Price Range Sell Pressure = (High - Close) / Price Range Buy Volume = Total Volume × Buy Pressure Sell Volume = Total Volume × Sell Pressure Delta = Buy Volume - Sell Volume ``` **Bid/Ask Estimation Method:** ``` Average Price = (High + Low + Close) / 3 Buy Volume = Close > Average ? Volume × 0.6 : Volume × 0.4 Sell Volume = Total Volume - Buy Volume ``` **Cumulative Method:** ``` Buy Volume = Close > Open ? Volume : Volume × 0.3 Sell Volume = Close ≤ Open ? Volume : Volume × 0.3 ``` **3. Point of Control (POC) Identification:** - Scans all price levels to find maximum volume concentration - POC represents the price level with highest trading activity - Acts as significant support/resistance level - **Developing POC Feature**: Tracks POC evolution in real-time via blue dotted trail, showing how institutional interest migrates throughout the session. Upward POC migration indicates accumulation patterns, downward migration suggests distribution, providing early trend signals before price confirmation. **4. Value Area Calculation:** - Starts from POC and expands up/down to encompass 70% of total volume - VAH (Value Area High): Upper boundary of value area - VAL (Value Area Low): Lower boundary of value area - Expansion algorithm prioritizes direction with higher volume **5. Adaptive Range Selection:** Based on profile type and timeframe optimization: - **N Bars Back**: Fixed lookback period with performance optimization (20-500 bars) - **Days Back**: Calendar-based analysis with automatic timeframe adjustment (1-365 days) - **Session**: Current trading session or custom session times ### Performance Optimization Features: - **Sampling Algorithm**: Reduces calculation load on large datasets while maintaining accuracy - **Memory Management**: Clears previous drawings to prevent performance degradation - **Safety Constraints**: Prevents excessive memory usage with configurable limits ## HOW TO USE THIS SCRIPT ### Initial Setup: 1. **Profile Configuration**: Select profile type based on trading style: - N Bars Back: Precise control over data range - Days Back: Intuitive calendar-based analysis - Session: Real-time session development 2. **Row Density**: Set number of rows (30 default) - more rows = higher resolution, slower performance 3. **Delta Method**: Choose calculation method based on market type: - Price Action: Best for trending markets - Bid/Ask Estimate: Good for ranging markets - Cumulative: Smoothed approach for volatile markets 4. **Visual Settings**: Configure colors, position (left/right), and display options ### Reading the Profile: **Volume Bars:** - **Length**: Represents relative volume at that price level - **Color**: Green = net buying pressure, Red = net selling pressure - **Intensity**: Darker colors indicate volume imbalances above threshold **Key Levels:** - **POC (Blue Line)**: Highest volume price - major support/resistance - **VAH (Purple Dashed)**: Value Area High - upper boundary of fair value - **VAL (Orange Dashed)**: Value Area Low - lower boundary of fair value - **Value Area Fill**: Shaded region showing main trading range **Developing POC Trail:** - **Blue Dotted Lines**: Show real-time POC evolution throughout the session - **Migration Patterns**: Upward trail indicates bullish accumulation, downward trail suggests bearish distribution - **Early Signals**: POC movement often precedes price movement, providing advance warning of institutional activity - **Institutional Footprints**: Reveals where smart money concentrated volume before final POC establishment ### Trading Applications: **Support/Resistance Analysis:** - POC acts as magnetic price level - expect reactions - VAH/VAL provide intermediate support/resistance levels - Profile edges show areas of low volume acceptance **Developing POC Analysis:** - **Upward Migration**: POC moving higher = institutional accumulation, bullish bias - **Downward Migration**: POC moving lower = institutional distribution, bearish bias - **Stable POC**: Tight clustering = balanced market, range-bound conditions - **Early Trend Detection**: POC direction change often precedes price breakouts **Entry Strategies:** - Buy at VAL with POC as target (in uptrends) - Sell at VAH with POC as target (in downtrends) - Breakout plays above/below profile extremes **Volume Imbalance Trading:** - Strong buying imbalance (>60% threshold) suggests continued upward pressure - Strong selling imbalance suggests continued downward pressure - Imbalances near key levels provide high-probability setups **Multi-Timeframe Context:** - Use higher timeframe profiles for major levels - Lower timeframe profiles for precise entries - Session profiles for intraday trading structure ## SCRIPT SETTINGS EXPLANATION ### Volume Profile Settings: - **Profile Type**: Determines data range for calculation -

Delta Volume Profile [BigBeluga]🔵Delta Volume Profile A dynamic volume analysis tool that builds two separate horizontal profiles: one for bullish candles and one for bearish candles. This indicator helps traders identify the true balance of buying vs. selling volume across price levels, highlighting points of control (POCs), delta dominance, and hidden volume clusters with remarkable precision. 🔵 KEY FEATURES Split Volume Profiles (Bull vs. Bear): The indicator separates volume based on candle direction: If close > open , the candle’s volume is added to the bullish profile (positive volume). If close < open , it contributes to the bearish profile (negative volume). ATR-Based Binning: The price range over the selected lookback is split into bins using ATR(200) as the bin height. Each bin accumulates both bull and bear volumes to form the dual-sided profile. Bull and Bear Volume Bars: Bullish volumes are shown as right-facing bars on the right side, colored with a bullish gradient. Bearish volumes appear as left-facing bars on the left side, shaded with a bearish gradient. Each bar includes a volume label (e.g., +12.45K or -9.33K) to show exact volume at that price level. Points of Control (POC) Highlighting: The bin with the highest bullish volume is marked with a border in POC+ color (default: blue). The bin with the highest bearish volume is marked with a POC− color (default: orange). Total Volume Density Map: A neutral gray background box is plotted behind candles showing the total volume (bull + bear) per bin. This reveals high-interest price zones regardless of direction. Delta and Total Volume Summary: A Delta label appears at the top, showing net % difference between bull and bear volume. A Total label at the bottom shows total accumulated volume across all bins. 🔵 HOW IT WORKS The indicator captures all candles within the lookback period . It calculates the price range and splits it into bins using ATR for adaptive resolution. For each candle: If price intersects a bin and close > open , volume is added to the positive profile . If close < open , volume is added to the negative profile . The result is two side-by-side histograms at each price level—one for buyers, one for sellers. The bin with the highest value on each side is visually emphasized using POC highlight colors. At the end, the script calculates: Delta: Total % difference between bull and bear volumes. Total: Sum of all volumes in the lookback window. 🔵 USAGE Volume Imbalance Zones: Identify price levels where buyers or sellers were clearly dominant. Fade or Follow Volume Clusters: Use POC+ or POC− levels for reaction trades or breakouts. Delta Strength Filtering: Strong delta values (> ±20%) suggest momentum or exhaustion setups. Volume-Based Anchoring: Use profile levels to mark hidden support/resistance and execution zones. 🔵 CONCLUSION Delta Volume Profile offers a unique advantage in market reading by separating buyer and seller activity into two visual layers. This allows traders to not only spot where volume was high, but also who was more aggressive. Whether you’re analyzing trend continuations, reversals, or absorption levels, this indicator gives you the transparency needed to trade with confidence.
