Impl Volty- ROC (Indicator)
DisclaimerInput Information
| Name | Expression | Default | Description |
| ROCLength | Numeric | 10 | Number of bars to include in calculation of the rate of change in implied volatility. |
| AlertLength | Numeric | 10 | Number of bars to use when searching for a new high or low IVROC value that will trigger an alert. |
| ColorNormLength | Numeric | 10 | Number of bars over which to normalize the indicator for gradient coloring. |
| UseGradientColoring | Numeric | 1 | Set to 1 to enable gradient (blended) coloring; set to 0 for no gradient coloring. |
| UpColor | Numeric | UpColorDefault |
When gradient coloring is enabled, this is the chart plot color or grid cell background color to use for indicator values that are relatively high over ColorNormLength bars. |
| DnColor | Numeric | DownColorDefault |
When gradient coloring is enabled, this is the chart plot color or grid cell background color to use for indicator values that are relatively low over ColorNormLength bars. |
| GridForegroundColor | Numeric | Black | Color to use for numbers in RadarScren cells when gradient coloring is enabled. |
Description
Impl Volty- ROC is an options-related indicator that plots the percentage change in implied volatility over a user-specified number of bars. .
Plot Information
| Number | Name | Default Color | Description |
| Plot1 | IV ROC | UpColor/DnColor | Plots the indicator ratio 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.
When gradient coloring is disabled, the Plot1 color is determined by settings in indicator properties dialog box.
If gradient coloring is enabled, the RadarScreen cell background is colored a mixture of UpColor and DnColor. Similarly, in Charting, the plot color is a mixture of UpColor and DnColor. As the Plot1 value goes relatively higher, the cell background (RadarScreen) or plot (Charting) will be colored more like UpColor. As the value goes relatively lower, the color will approach DnColor.
