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.
