Standalone CVD with filled area visualization: per-bar rectangles, candlestick mode, and session reset
CVD Filled Area computes Cumulative Volume Delta internally and draws it as a filled area with per-bar rectangles. It supports two outline modes (stair-step and candlestick), session-based CVD reset, and an optional zero line.
The study computes CVD directly from bid and ask volume data, with no external CVD study needed. Each bar's delta (ask volume minus bid volume) is accumulated to produce the CVD line, which is then rendered as a filled area.
Four reset modes control when the CVD accumulation resets to zero:
Each bar gets a rectangle fill from zero to the CVD value:
The fill transparency is adjustable from 0% (fully opaque) to 100% (invisible).
Two outline rendering modes:
Each mode uses separate colors for positive and negative sections, with configurable line and wick widths.
An optional horizontal zero line provides a visual reference. Its color, width, and style (solid, dash, dot, dash-dot) are all configurable.
