Revealing Institutional Footprints: The iSolani Volume-Powered Order Block System
Where Smart Money Leaves Its Mark – Automated Zone Detection for Discretionary Traders
Core Methodology
- Pressure-Weighted Volume Analysis
Calculates directional commitment using candle position:
Buying Pressure = Total Volume × (Closing Price – Low) / (High – Low)
Selling Pressure = Total Volume × (High – Closing Price) / (High – Low)
Normalizes values against 31-period EMAs to filter retail noise - Adaptive Block Triggering
Identifies significant zones when:
Absolute Buy/Sell Difference > 4× SMA of Historical Differences (default)
Price closes bullishly (green block) or bearishly (red block) - Self-Maintaining Visualization
- Blocks auto-extend rightward until price breaches critical level
- Invalidated zones removed in real-time via array management
- Dynamic Threshold Adjustment
Multiplier parameter (default 4) automatically scales with market volatility - Institutional-Grade Metrics
Blocks display:
Volume disparity in absolute terms
Percentage deviation from 33-period average
Directional bias through color-coding - Efficient Memory Handling
O(n) complexity cleanup routine prevents chart lag
- Calculates real-time buy/sell pressure ratios
- Compares to historical average (31-period default)
- Generates semi-transparent zones (85% opacity) at spike locations
- Monitors price interaction with block boundaries
- Automatically retracts invalid zones
- Sensitivity: 4× multiplier (ideal for 15m-4h charts)
- Visuals: Red/green blocks with white text labels
- Duration: 50-bar default extension
- Volume Baseline: 33-period EMA filter
- Boundary Check: Close beyond block high/low triggers deletion
This system transforms raw market data into a institutional roadmap – not by predicting turns, but by revealing where concentrated volume makes turns statistically probable. The color-coded blocks serve as persistent yet adaptive markers of where professional liquidity resides. - Blocks auto-extend rightward until price breaches critical level
