Market Synopsis

The Volume Ratio indicator calculates an exponential moving average of the ratio between up and down volume. The exponential average is then plotted as an oscillator around a zero line.

Volume can provide insight into the strength or weakness of a price trend. This indicator plots positive values above the zero line, and negative below. A positive value suggests there is enough market support to continue to drive price activity in the direction of the current trend. A negative value suggests there is a lack of support and prices may begin to become stagnant or reverse.

Plot Information

Number Name Default Color Description
Plot1 VolRatioAvg Yellow/Cyan Plots the Volume Ratio value.
Plot2 ZeroLine Dark Green Plots a reference line at zero.

When applied to a chart, this indicator contains two plots, displayed in a separate subgraph from the price data.

Set either UpColor and/or DnColor to -1 to disable gradient plot coloring.  When disabled, Plot1 color is determined by settings in indicator properties dialog box.  Plot2 (ZeroLine) color always comes from indicator properties dialog box.

  This indicator only returns significant results when applied to bars with a time interval of tick or intraday.
