Trend Volume Accumulations

Trend Volume Accumulations (TVA) was built to answer a question most volume tools skip: do moves running on rising volume behave differently from moves running on fading volume? Taking its cue from Weis Wave Volume, it accumulates volume into waves (rising volume forms positive waves, declining volume carves negative ones), while wave color tracks the trend itself, read from the sign of a rolling linear regression: cyan-to-blue shades for up, orange-to-red shades for down, deepening as a wave nears its level (flat blue and red with Gradient off).

How to Trade the Trend Volume Accumulations?

• Blue vs red waves: the direction read. Blue waves print while the regression slopes up, red while it slopes down.
• Wave amplitude: tall waves show real participation behind the trend; shallow waves flag reduced activity, a market half asleep.
• Wave reaching the upper or lower level: each level is built from the cumulative mean of its side's waves. A wave stretching that far warns a trend reversal may be near.

The upper level derives from waves fed by rising volume and the lower from waves fed by declining volume, so both thresholds adapt to how the market has actually been trading rather than sitting at fixed values.

Trend Volume Accumulations Settings

• Length: the period the indicator considers.
• Src: the data source for the calculation.
• Linearity: higher values mute one-off volume fluctuations, producing smoother, more linear waves.
• Mult: scales how far the upper and lower levels sit from zero.
• Gradient (enabled by default): toggles gradient coloring of the waves.
