Cumulative Volume Indicator with Up and Down Volume Views
Summary
This document describes a volume indicator that aggregates volume over a selectable lookback period. Each bar's volume is assigned to the up or down side according to whether the close is above the previous close; the two sums can be displayed as a net cumulative series or as separate positive and negative histograms. The indicator also offers relative or absolute presentation, configurable color inversion, and an option to filter auction-related bars using price and volume conditions.
The included formula shows how those choices are implemented, but it supplies no trading rules, examples, or performance tests. The up/down classification is based only on close-to-close direction, so it does not reveal actual buyer- versus seller-initiated volume. The auction filter's conditions are not explained in market terms, and scaling volume by a constant affects the displayed magnitude. The indicator is therefore a visualization of directional volume proxies, not evidence of order flow or a validated signal.
Key ideas
- The indicator sums volume over a user-selected period.
- Bars are classified as up or down based on the current close relative to the previous close.
- Users can view net cumulative volume or separate up and down volume histograms.
- Display options include relative or absolute values, color inversion, and an auction-bar filter.
- The close-direction classification is only a proxy and does not establish trade-side order flow.
