The Weis Waves indicator is based on the original work of David Weis, who integrated Wyckoff analysis with modern charting techniques. It analyzes volume waves to identify when informed market participants ("smart money") are actively involved or withdrawing, following the Wyckoff principle that volume confirms price movements. This indicator is used primarily for trend confirmation, detecting momentum exhaustion, spotting divergences, and identifying absorption phases in the market. It processes bar data with volume information and provides visualizations, filters, and trading signals related to trend strength, reversals, and divergences. The indicator is categorized under volume-based tools and supports analysis of supply and demand zones, imbalances, and on-balance volume concepts.
