# Liquidity Structure & Order Flow Liquidity Structure & Order Flow is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®. Liquidity Structure & Order Flow fuses a volume profile, per-bin delta coloring, and liquidity-void detection into one view of where the market is heavy, who is aggressive, and where price can slip fast. Z-score volume bubbles, dynamic volume ribbons, and a metrics dashboard round it out for day, swing, and scalp traders alike. - Indicator in the LuxAlgo Library, by LuxAlgo, published Feb 19, 2026. - Access: free. - Concepts: [Liquidity Pool](https://www.luxalgo.com/library/concept/liquidity-pool/) (primary), [Break of Structure](https://www.luxalgo.com/library/concept/break-of-structure/), [Volume Delta](https://www.luxalgo.com/library/concept/volume-delta/) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=cmpwn34i7004cvhsggfles4qv - Page: https://www.luxalgo.com/library/indicator/liquidity-structure-order-flow/ **Liquidity Structure & Order Flow** shows where the market is heavy, who is aggressive inside that weight, and where price can slip fast. A lookback volume profile sets the value area (VAH to VAL) and point of control, mapping the [clustered liquidity](https://www.luxalgo.com/library/concept/liquidity-pool/) that anchors levels; a backdrop colors each price bin inside the value area by EMA-smoothed [delta flow](https://www.luxalgo.com/library/concept/volume-delta/); and the widest void (the longest run of bins under 15% of POC volume) is flagged as the low-friction lane. ## How to Trade the Liquidity Structure & Order Flow? - **Value area as regime**: inside VAH–VAL the market is balanced and range tactics apply; a break beyond it signals imbalance and often a fresh trend leg. - **Absorption at the edges**: strong delta into a value-area edge without follow-through suggests passive orders defending the level: reversal or fake-breakout risk. - **Widest void as target**: price tends to cross it quickly toward the next high-liquidity node: natural breakout targets and take-profit zones. - **Unusual Volume Bubbles**: volume Z-scored against a 200-period baseline prints as deviation-scaled bubbles; extremes at the POC, VAH/VAL, or swing points strengthen the reaction case. - **Volume ribbons**: cumulative curves above (red) and below (green) the midpoint show which side of the range is heavier. ## Liquidity Structure & Order Flow Settings - **Lookback Period**: bars feeding the volume profile. - **Weight Recent Volume**: tilts the profile toward fresh activity. - **Value Area %**: the share of volume the value area contains. - **Profile Smoothing**: reduces heatmap noise. - **Show Volume Delta Panel / Delta Intensity / Delta Smoothing Length**: the delta backdrop's toggle, saturation, and EMA length. - **Sensitivity (Z-Score)**: the bubble trigger threshold; bubble size scales automatically with how far the volume Z-score exceeds it (the Min/Max Bubble Size inputs currently have no effect). - **Show Heatmap, Highlight Widest Void, Curves X-Offset, Dashboard**: display layers, with the dashboard reporting Mass Skew, Distance to POC, and Aggregated Delta. ## Frequently Asked Questions ### Which trading styles does it suit? It slots into breakout trading, mean reversion inside the value area, liquidity-sweep models, and order-block or market-structure systems. Day, swing, and scalp traders can anchor decisions to the same profile. ### How does it differ from the Liquidity Delta Profiler? The [Liquidity Delta Profiler](https://www.luxalgo.com/library/indicator/liquidity-delta-profiler/) runs delta analysis inside discrete swing-based zones and scores sweep reversals. This tool profiles the whole lookback (value area, voids, bubbles, ribbons) for a market-wide read. ### How do I access Liquidity Structure & Order Flow? Get it free from the LuxAlgo Library.
