Market Synopsis
The Swing Index indicator assigns a Swing Index value from 0 to 100 for an up bar and 0 to -100 for a down bar. This indicator uses the current bar's Open, High, Low, and Close as well as the previous bar's Open and Close to calculate the Swing Index values. If the Swing Index crosses over 0, a short-term price increase is likely. Conversely, a cross below 0 suggests a decline in market price. A larger or smaller swing index value indicates the severity of the market's increase or decline in price.
Plot Information
| Number | Name | Default Color | Description |
| Plot1 | SwingX | Yellow/Cyan | Plots the SwingIndex value. |
| Plot2 | ZeroLine | Dark Green | Plots a reference line at zero. |
When applied to a chart, this indicator displays two plots 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.
