# Volumetric Order Flow Structure Volumetric Order Flow Structure is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®. Volumetric Order Flow Structure maps market-structure breaks and the zones behind them: BOS and CHoCH events plot with bars scaled by where the breakout candle closed in its range, order blocks carry stepped 15-row profiles of their pivot candle with the widest row in orange, and manipulation bubbles flag wicks that raid liquidity without closing through. - Indicator in the LuxAlgo Library, by LuxAlgo, published Feb 16, 2026. - Access: free. - Concepts: [Volume Delta](https://www.luxalgo.com/library/concept/volume-delta/) (primary), [Break of Structure](https://www.luxalgo.com/library/concept/break-of-structure/) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=cmpwn79p100a8vhsgxw1t4roc - Page: https://www.luxalgo.com/library/indicator/volumetric-order-flow-structure/ **Volumetric Order Flow Structure** judges market structure by the participation behind it. When price breaks a level, glowing bars fill horizontally in proportion to where the breakout candle closed within its own range, so breaks that close near the extreme stand apart from hesitant ones. Each active supply or demand zone carries a stepped 15-row profile of its pivot candle, a fixed shape that widens toward the candle's middle and body rather than a measured volume distribution, with its widest row highlighted in orange. ## How to Trade the Volumetric Order Flow Structure? - **BOS with a wide volumetric bar**: a [break of structure](https://www.luxalgo.com/library/concept/break-of-structure/) whose breakout candle closed near its extreme favors continuation; a narrow bar warns the break closed without conviction. - **CHoCH**: a change of character gives early caution that the prevailing trend may be reversing. - **Orange row**: a fixed reference near the middle of the pivot candle, favoring its body; refine entries and stop placement around it instead of treating the whole zone as one undifferentiated block. - **Manipulation bubbles**: a wick pushing beyond a zone without closing through it flags a likely liquidity raid, engineered stop-triggering that often precedes a reversal or a continuation after the grab. Zones extend across the chart until price closes decisively beyond them; the overlap filter keeps only the highest-volume block when zones stack, and ATR-based scaling keeps thickness and labels proportional across assets. ## Volumetric Order Flow Structure Settings - **Pivot Length**: the lookback for structural highs and lows. Larger values isolate major structure, smaller ones catch intraday shifts. - **Volume Lookback**: currently has no effect on the plotted output; manipulation bubbles are scaled against the highest volume of the last 200 bars. - **Max Recent Blocks**: how many active zones stay on the chart. - **Base Transparency / Hide Overlapping Blocks**: zone opacity, and whether overlapping blocks are reduced to the one whose pivot candle had the highest volume. - **Show Manipulation Bubbles / Bubble Sensitivity**: toggles the raid markers and how sharply their size responds to volume. ## Frequently Asked Questions ### What sizes the manipulation bubbles? Relative volume: the heavier the trade behind the raid, the larger the bubble, with labels reporting the volume involved. Large bubbles at zone edges deserve the closest attention. ### What separates it from a standalone order-block tool? A focused build like the [Order Block Detector](https://www.luxalgo.com/library/indicator/order-block-detector/) concentrates on locating blocks; this one adds a stepped profile of each zone's pivot candle, structure-break bars scaled by the breakout close, and volume-sized raid detection around those same zones. ### How do I get access to Volumetric Order Flow Structure? The indicator is free on the LuxAlgo Library, no subscription required. It runs on forex, stocks, indices, and crypto alike. You can also copy the source code from this page and run it anywhere Pine Script® runs. ## Related indicators - [Volume Delta Candles](https://www.luxalgo.com/library/indicator/volume-delta-candles/) (Volume Delta): markdown at https://www.luxalgo.com/library/indicator/volume-delta-candles.md - [Volume Delta Methods (Chart)](https://www.luxalgo.com/library/indicator/volume-delta-methods-chart/) (Volume Delta): markdown at https://www.luxalgo.com/library/indicator/volume-delta-methods-chart.md - [Volume Delta Trailing Stop](https://www.luxalgo.com/library/indicator/volume-delta-trailing-stop/) (Volume Delta): markdown at https://www.luxalgo.com/library/indicator/volume-delta-trailing-stop.md - [Volume Footprint](https://www.luxalgo.com/library/indicator/volume-footprint/) (Volume Delta): markdown at https://www.luxalgo.com/library/indicator/volume-footprint.md - [Delta ZigZag](https://www.luxalgo.com/library/indicator/delta-zigzag/) (Volume Delta): markdown at https://www.luxalgo.com/library/indicator/delta-zigzag.md - [Delta Flow Profile](https://www.luxalgo.com/library/indicator/delta-flow-profile/) (Volume Delta): markdown at https://www.luxalgo.com/library/indicator/delta-flow-profile.md - [Market Structure (Breakers)](https://www.luxalgo.com/library/indicator/market-structure-breakers/) (Break of Structure): markdown at https://www.luxalgo.com/library/indicator/market-structure-breakers.md - [DTFX Algo Zones](https://www.luxalgo.com/library/indicator/dtfx-algo-zones/) (Break of Structure): markdown at https://www.luxalgo.com/library/indicator/dtfx-algo-zones.md --- Source: https://www.luxalgo.com/library/indicator/volumetric-order-flow-structure/ (LuxAlgo Library).
