# Institutional Order Flow Strength Classifier Detects unmitigated order blocks at confirmed structure breaks and scores each zone from 0-100% using displacement and relative volume. Overlap filtering removes redundant boxes and a background plot tracks the strongest active zone. For smart-money and supply-demand traders who want ranked institutional levels instead of clutter. - Indicator in the LuxAlgo Library, by LuxAlgo, published Feb 12, 2026. - Access: free. - Concepts: [Institutional Order Flow](https://www.luxalgo.com/library/concept/institutional-order-flow/) (primary) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=cmpwn2n3m003nvhsgy9iuqtyv - Page: https://www.luxalgo.com/library/indicator/institutional-order-flow-strength-classifier/ **Institutional Order Flow Strength Classifier** detects unmitigated order blocks at confirmed structure breaks and grades every zone from 0-100%, so the levels most likely to carry [institutional order flow](https://www.luxalgo.com/library/concept/institutional-order-flow/) stand apart from ordinary pivots. The score blends two weighted measures: displacement (how far price expanded away from the zone relative to its size) at 60%, and the zone candle's volume against its 20-period average at 40%. ## How to Trade the Institutional Order Flow Strength Classifier? - **Above 70%**: strong displacement on above-average volume, candidate zones for limit-order entries and major supply or demand. - **40-70%**: continuation-grade zones, commonly used for pullback entries, scaling, or stop placement within a trend. - **Below 40%**: weak displacement or thin volume, zones that often behave as internal liquidity and get swept rather than respected. - **Strongest OB background**: the solid filled area marks the highest-ranked active block within your buffer, a fast reference for bias and risk decisions. Mitigation keeps the map current: a bullish zone is removed once price crosses below its bottom, a bearish zone once price crosses above its top. The Zonal Overlap system hides redundant boxes that stack in the same price region, leaving one representative zone per area. ## Institutional Order Flow Strength Classifier Settings - **Pivot Lookback**: bars required to confirm the pivots behind each structure break. - **Max Unmitigated OBs**: how many active zones remain on the chart. - **Hide Overlapped Zones**: collapses blocks that share a price region. - **Show Strength Labels**: prints each zone's percentage score. - **Show Strongest OB Plot** and **Strongest OB Buffer Size**: toggle the background highlight and set how many recent zones are scanned for it. ## Frequently Asked Questions ### How is the strength score calculated? Displacement carries 60% of the weight and relative volume the other 40%, producing a single 0-100% grade. Large displacement shows urgency in how price left the zone; the volume component confirms capital was actually behind it. ### How does it differ from a standard order block tool? Standard detectors mark every qualifying zone without ranking them. If you prefer that leaner presentation, the [Order Block Detector](https://www.luxalgo.com/library/indicator/order-block-detector/) covers it. This classifier adds the scoring, overlap filtering, and strongest-zone tracking on top. ### How do I access the Institutional Order Flow Strength Classifier? It is available free in the LuxAlgo Library. From this page you can also open the classifier in Quant, our coding agent, to test how the ranked zones behave on your markets. You can also copy the source code from this page and run it anywhere Pine Script® runs. ## Related indicators - [Ultimate AMD Indicator](https://www.luxalgo.com/library/indicator/ultimate-amd-indicator/) (Accumulation-manipulation-distribution): markdown at https://www.luxalgo.com/library/indicator/ultimate-amd-indicator.md - [AMD FVG Trade Setup](https://www.luxalgo.com/library/indicator/amd-fvg-trade-setup/) (Accumulation-manipulation-distribution): markdown at https://www.luxalgo.com/library/indicator/amd-fvg-trade-setup.md - [FVG + Liquidity Sweep + CISD](https://www.luxalgo.com/library/indicator/fvg-liquidity-sweep-cisd/) (Change in State of Delivery): markdown at https://www.luxalgo.com/library/indicator/fvg-liquidity-sweep-cisd.md - [HTF CISD Projections](https://www.luxalgo.com/library/indicator/htf-cisd-projections/) (IPDA & Price Delivery Theory): markdown at https://www.luxalgo.com/library/indicator/htf-cisd-projections.md - [HTF PO3](https://www.luxalgo.com/library/indicator/htf-po3/) (Accumulation-manipulation-distribution): markdown at https://www.luxalgo.com/library/indicator/htf-po3.md - [CISD Projections](https://www.luxalgo.com/library/indicator/cisd-projections/) (IPDA & Price Delivery Theory): markdown at https://www.luxalgo.com/library/indicator/cisd-projections.md - [SMT Divergences](https://www.luxalgo.com/library/indicator/smt-divergences/) (Smart Money Technique Divergence): markdown at https://www.luxalgo.com/library/indicator/smt-divergences.md - [Market Maker Models](https://www.luxalgo.com/library/indicator/market-maker-models/) (Smart Money Concepts / ICT): markdown at https://www.luxalgo.com/library/indicator/market-maker-models.md --- Source: https://www.luxalgo.com/library/indicator/institutional-order-flow-strength-classifier/ (LuxAlgo Library).
