Liquidity Structure & Order Flow
By LuxAlgoFeb 19, 2026
Liquidity Structure & Order Flow is an indicator on Vela, our next-generation charting platform, written in Pine Script®.
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 that anchors levels; a backdrop colors each price bin inside the value area by EMA-smoothed delta flow; 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.
