Volume Shelves — Support & Resistance
Trend Edge identifies volume shelves: price zones where historically elevated trading volume
creates structural support or resistance. A volume shelf forms when a disproportionate share of cumulative
volume was transacted at a specific price level, making it a high-conviction anchor for future price reactions.
