Volumeanalysis — Indicators and Strategies

LibVolm Library "LibVolm" This library provides a collection of core functions for volume and money flow analysis. It offers implementations of several classic volume-based indicators, with a focus on flexibility for applications like multi-timeframe and session-based analysis. Key Features: 1. **Suite of Classic Volume Indicators:** Includes standard implementations of several foundational indicators: - **On Balance Volume (`obv`):** A momentum indicator that accumulates volume based on price direction. - **Accumulation/Distribution Line (`adLine`):** Measures cumulative money flow using the close's position within the bar's range. - **Chaikin Money Flow (`cmf`):** An oscillator version of the ADL that measures money flow over a specified lookback period. 2. **Anchored/Resettable Indicators:** The library includes flexible, resettable indicators ideal for cyclical analysis: - **Anchored VWAP (`vwap`):** Calculates a Volume Weighted Average Price that can be reset on any user-defined `reset` condition. It returns both the VWAP and the number of bars (`prdBars`) in the current period. - **Resettable CVD (`cvd`):** Computes a Cumulative Volume Delta that can be reset on a custom `reset` anchor. The function also tracks and returns the highest (`hi`) and lowest (`lo`) delta values reached within the current period. (Note: The delta sign is determined by a specific logic: it first checks close vs. open, then close vs. prior close, and persists the last non-zero sign). 3. **Volume Sanitization:** All functions that use the built-in `volume` variable automatically sanitize it via an internal function. This process replaces `na` values with 0 and ensures no negative volume values are used, providing stable calculations. --- **DISCLAIMER** This library is provided "AS IS" and for informational and educational purposes only.

Parameters: price (float) : series float Source price series, typically the close. Returns: series float Cumulative OBV value. adLine() Computes the Accumulation/Distribution Line (AD Line). Returns: series float Cumulative AD Line value. cmf(length) Computes Chaikin Money Flow (CMF). Parameters: length (int) : series int Lookback length for the CMF calculation. Returns: series float CMF value. vwap(price, reset) Calculates an anchored Volume Weighted Average Price (VWAP). Parameters: price (float) : series float Source price series (usually *close*). reset (bool) : series bool A signal that is *true* on the bar where the accumulation should be reset. Returns: vwap series float The calculated Volume Weighted Average Price for the current period. prdBars series int The number of bars that have passed since the last reset. cvd(reset) Calculates a resettable, cumulative Volume Delta (CVD). It accumulates volume delta and tracks its high/low range. The accumulation is reset to zero whenever the `reset` condition is true. This is useful for session-based analysis, intra-bar calculations, or any other custom-anchored accumulation. Parameters: reset (bool) : series bool A signal that is *true* on the bar where the accumulation should be reset. Returns: cum series float The current cumulative volume delta. hi series float The highest peak the cumulative delta has reached in the current period. lo series float The lowest trough the cumulative delta has reached in the current period.

WhispererRealtimeVolume Library "WhispererRealtimeVolume" ▮ Overview The Whisperer Realtime Volume Library is a lightweight and reusable Pine Script® library designed for real-time volume analysis. It calculates up, down, and neutral volumes dynamically, making it an essential tool for traders who want to gain deeper insights into market activity. This library is a simplified and modular version of the original "Realtime Volume Bars w Market Buy/Sell/Neutral split & Mkt Delta" indicator by the_MarketWhisperer , tailored for integration into custom scripts. How bars are classified - Up Bars If the current bar’s closing price is higher than the previous bar’s closing price, it is classified as an up bar. Volume handling: The increase in volume for this bar is added to the up volume. This represents buying pressure. - Down Bars If the current bar’s closing price is lower than the previous bar’s closing price, it is classified as a down bar. Volume handling: The increase in volume for this bar is added to the down volume. This represents selling pressure. - Neutral Bars If the current bar’s closing price is the same as the previous bar’s closing price, it is classified as a neutral bar. Volume handling: If neutral volume is enabled, the volume is added to the neutral volume. If neutral volume is not enabled, the volume is assigned to the same direction as the previous bar (up or down). If the previous direction is unknown, it is added to the neutral volume. ▮ What to look for Real-Time Volume Calculation : Analyze up, down, and neutral volumes in real-time based on price movements and bar volume. Customizable Start Line : Add a visual reference line to your chart for better context by viewing the starting point of real-time bars. Ease of Integration : Designed as a library for seamless use in other Pine Script® indicators or strategies. ▮ How to use Example code: //@version=6 indicator("Volume Realtime from Whisperer") import andre_007/WhispererRealtimeVolume/4 as MW MW.displayStartLine(startLineColor = color.gray, startLineWidth = 1, startLineStyle = line.style_dashed, displayStartLine = true, y1=volume, y2=volume + 10) = MW.mw_upDownVolumeRealtime(true) plot(volume, style=plot.style_columns, color=color.gray) plot(volumeUp, style=plot.style_columns, color=color.green) plot(volumeDown, style=plot.style_columns, color=color.red) plot(volumeNeutral, style=plot.style_columns, color=color.purple) ▮ Credits This library is inspired by the original work of the_MarketWhisperer , whose "Realtime Volume Bars" indicator served as the foundation.

PointofControl Library "PointofControl" POC_f() The genesis of this project was to create a POC library that would be available to deliver volume profile information via pine to other scripts of indicators and strategies. This is the indicator version of the library function. A few things that would be unique with the built in - it allows you to choose the kind of reset of the period, day/week or bars. This is simple enough to expand to other conditions - it resets on bar count starting from the beginning of the data set (bar index =0) vs bars back from the end of the data set - A 'period' in this context is the time between resets - the start of the POC until it resets (for example at the beginning of a new day or week) - it will calculate an increment level rather than the user specifying ticks or price brackets - it does not allow for setting the # of rows and then calculating the implied price levels - When a period is complete it is often useful to look back at the POCs of historical periods, or extend them forward. - This script will find the historical POCs around the current price and display them rather than extend all the historical POC lines to the right - This script also looks across all the period POCs and identifies the master POC or what I call the Grand POC, and also the next 3 runner up POCs There is a matching indicator to this library
