The Cumulative Delta is the algebraic sum of the single delta volume values. In comparison to [[Volume Delta]], the Cumulative Delta is not based on regular bars. When Cumulative Delta chart type is used, the price scale to the right is transformed into volume scale and the formed bars represent not volume within regular price bars, but accumulated delta (buy - sell) of traded volume per specified resolution. It is used for analysis only, not for trading directly from this chart type.
