OI: CVD Line

OI: CVD Line is a simple price-overlay CVD tool designed to make order-flow context easy to read directly on the chart. It builds a cumulative volume delta line from lower-timeframe volume data, then maps it onto the price scale so you can compare “flow” vs price without needing a separate pane.

This script is free to use but published as protected (closed source).

What you see

A CVD line overlaid on price (coloured up/down by its current direction)

An optional guide moving average on price for quick reference

An optional strength band around price when flow conditions are unusually strong

Optional flip markers when the internal bias crosses through neutral

How to use it

Confirm direction: When the CVD line is rising and price structure agrees, it often supports continuation conditions.

Spot disagreement: When price pushes but the CVD line fails to follow (or rolls over), it can hint at weakening participation.

Filter trades: Use the line direction and/or strength band as a context filter rather than a standalone entry system.

Inputs (explained in “how it helps” terms)

Reset / anchor period: Controls how often the cumulative line resets (broader vs more reactive context).

Sampling timeframe: The lower timeframe used to build the CVD (more detail vs smoother/lighter).

Line smoothness / smoothing style: Adjusts responsiveness vs noise.

Overlay behaviour + fit window: Controls how tightly the CVD line is fit to recent price movement (looser/trend-focused vs tighter/window-focused).

Strength band + threshold: Shows a band only when flow strength is meaningfully above “normal”.

Mark bias flips: Adds small markers when the internal bias flips through neutral.

Notes

This is a visual context tool (not an auto-trading system).

Any live-bar indicator can change during the current candle; signals are most reliable when confirmed on candle close.

Requires symbols/exchanges where the underlying volume data is available and meaningful.
