Lesson / WY-A-2
Delta for one bar or sample is classified aggressive buying minus classified aggressive selling: Delta=Σ_p Ask(p)-Σ_p Bid(p). If unclassified volume U exists in the same scope, total volume V=Σ_p Ask(p)+Σ_p Bid(p)+U; Delta uses only classified volume. Sources with different unclassified proportions should not have their Delta directly compared even at equal total volume.
