Price Action

This Pine Script code creates an indicator that plots price channels for volatility analysis:

The main parameter is the period length (default is 30), used to calculate volatility with ATR (Average True Range). Data retrieval: The indicator takes the closing price and uses it for calculations. Channel calculation: Based on volatility, three levels of channels are created: the first is the base channel, while the second and third are expanded by 8% and 16%.

First-level channels: The upper and lower boundaries of the channel are calculated based on volatility. This uses the previous bar's closing price, adjusted by a volatility coefficient.

Second and third-level channels: These channels expand by 8% and 16%, respectively, from the base channel. This creates zones that can indicate increasing or decreasing market volatility.

Each channel uses different colors and transparency levels:

• The upper and lower boundaries of the first channel have solid colors.
  
• The second channel boundaries are more transparent to denote extended levels.
  
• The third channel boundaries are also transparent, indicating the widest range of deviation.
  
• Visualization: Channels are displayed with different colors and transparency levels to illustrate price ranges and volatility changes.
  

Purpose: The indicator helps traders visualize price ranges and assess market volatility, which is useful for making trading decisions.

Practical application: This indicator assists traders in evaluating market volatility and building trading strategies based on price ranges. The extended channels can be used to identify potential reversal or trend continuation zones.
