This script is used to display three technical indicators on a chart: VWAP, Bollinger Bands, and ATR Bands.
Bollinger Bands are a technical analysis tool that uses two standard deviations from a simple moving average to create a range of likely price action. The Bollinger Bands consist of a center line (the simple moving average) and two price channels (the upper and lower bands). The width of the bands can be used as a measure of volatility. When the bands are narrow, it indicates that volatility is low, and when the bands are wide, it indicates that volatility is high.
ATR Bands use the Average True Range (ATR) indicator to create an upper and lower band around the price. The ATR measures the volatility of the security, and the bands adjust accordingly.
Traders and investors can use this script to identify potential buy and sell signals. For example, if the price is trading near the lower Bollinger Band and the ATR Bands are narrow, it could indicate that the security is oversold and that it's a good time to buy.
