value is the VPIN score for the requested window. Higher values indicate more imbalanced buy and sell flow across equal-volume buckets, which can suggest more informed or one-sided trading pressure.

Reference: Easley, López de Prado, and O’Hara (2012), who extended the logic behind PIN to Volume-Synchronized PIN (VPIN).

value is Kyle’s lambda, estimated here as the slope of the relationship between short-interval price changes and signed order flow. Higher absolute values indicate greater price impact per unit of net flow and therefore thinner liquidity.

Reference: Kyle (1985), which introduced lambda as a measure of market depth and price impact in continuous auctions.
