DisclaimerInput Information
| Name | Expression | Default | Description |
| StdDevLength | Numeric | 20 | Sets the number of bars to include when calculating the standard deviation. |
| HiPercent | Numeric | 80 | High reference value used to plot a high reference line in a chart and to set the high plot color for a chart line or cell background. |
| LoPercent | Numeric | 20 | Low reference value used to plot a low reference line in a chart and to set the high plot color for a chart line or cell background. |
| UseGradientColoring | Numeric | 1 | Set to 1 for gradient (blended) coloring; set to 0 for no gradient coloring. |
| UpColor | Numeric | Magenta | Color to use for indicator values that are relatively high over ColorNormLength bars. Set to -1 to disable gradient color plotting. |
| DnColor | Numeric | Cyan | Color to use for indicator values that are relatively low over ColorNormLength bars. Set to -1 to disable gradient color plotting. |
| GridForegroundColor | Numeric | Black | Color to use for numbers in RadarScreen cells when gradient coloring is enabled, that is, when both UpColor and DnColor are set to non-negative values. |
Description
Volty SDev Stoch is an options-related indicator that plots the current standard deviation of closing prices as a percentage of the standard deviation of closing prices over its 52-week range. The calculation is similar to that of a 52 week stochastic, however to improve speed, this indicator does not call the Stochastic function.
Plot Information
| Number | Name | Default Color | Description |
| Plot1 | SD Pct | Magenta/Cyan | Plots the std dev value. |
| Plot2 | Hi Pct | Dark Green | Plots the high percentage reference line. |
| Plot3 | Lo Pct | Dark Green | Plots the low percentage reference line. |
When applied to a chart, this indicator displays three plots in a separate subgraph from the price data.
Set UseGradientColoring to 0 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.
