Impl Volty- ROC (Indicator)Analysis Techniques & Strategies
Impl Volty- ROC (Indicator)| 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. |
| UpColor | Numeric | Red | Color to use for indicator values that are relatively high over ColorNormLength bars. Set to -1 to disable gradient color plotting. |
| DnColor | Numeric | Green | 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. |
Impl Volty- ROC is an options-related indicator that plots the percentage change in implied volatility over a user-specified number of bars. .
| Number | Name | Default Color | Description |
| Plot1 | IV ROC | Yellow/Magenta | Plots the oscillator 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.
