The ATR is a great indicator, but for me, it does not define the volatility of an asset I am looking at well enough. So I've adjusted it to be displayed as the usual ATR and a percentage of the closing prince (which to me tells a better story). I find this useful if I am looking through many assets and have to create a quick picture of volatility.
Indicator Definition: The script starts by defining an indicator named "ATR Percentage" that will be displayed in a separate pane (not overlayed on the price chart).
Input for ATR Period: The user can set the period for calculating the ATR through an input field.
ATR Calculation: The ta.atr function calculates the Average True Range based on the specified period.
ATR Percentage Calculation: The ATR value is converted to a percentage of the current closing price using (atrValue / close) * 100.
Plotting:
The script plots both the ATR value and its percentage on the chart.
A horizontal line at zero is added for reference.
Label Display: An optional label displays the current ATR percentage at every 10th bar to avoid cluttering the chart.
Background Color: A light blue background is added to visually separate the ATR indicator from other indicators.
