Peak Reaction Zones by BigBeluga updated script with alerts

Peak Reaction Zones [BigBeluga] Script - Description and Usage
Thanks to BIgBeluga for this script. I have added alert function to this script and change default setting parameters, which I think works better in 15 min chart, however user can play and update setting as per user requirements.

This Pine Script is designed to help traders identify potential breakout zones in the market. It automatically calculates reaction zones based on the highest and lowest prices over a specified lookback period. These zones can then be used as references to track significant price movements, with alerts for when breakouts occur.

The script plots two reaction zones:

High Zone (Orange): The upper level defined by the highest price over a specified lookback period.
Low Zone (Blue): The lower level defined by the lowest price over a specified lookback period.
Additionally, alerts are triggered when price breaks above or below these zones, providing real-time notifications of potential market movements.

Key Inputs:
Lookback Period (lookback):

This input determines the number of bars (periods) to look back for calculating the highest and lowest prices.
Default: 72
Zone Width Multiplier (multiplier):

This input is a multiplier that adjusts the width of the zones based on the Average True Range (ATR). A higher multiplier widens the zone.
Default: 1
High Zone Color (high_col):

The color of the high zone, typically orange for the upper zone.
Default: orange
Low Zone Color (low_col):

The color of the low zone, typically blue for the lower zone.
Default: blue
How the Script Works:
Zone Calculation:

The script calculates the highest and lowest prices over a user-defined lookback period.
These prices define the high zone and low zone, respectively.
The width of each zone is adjusted using the ATR (Average True Range) and the multiplier input.
Plotting the Zones:

Once the zones are calculated, the script plots two horizontal lines representing the high zone (upper) and low zone (lower).
Dashed lines are also drawn to show the boundaries of the zones, and labels display the price values for both zones.

Set Alerts:

You can set alerts in TradingView based on the alert conditions that are programmed in the script.

Set Alerts:

Right-click on the chart and select "Add Alert."
In the "Condition" field, choose the alert options related to your script, such as:
"Price broke above the low zone"
"Price broke below the high zone"
Choose your preferred alert frequency (e.g., "Once per bar").
Set your notification method (e.g., pop-up, email, webhook).
Click "Create" to set up the alert.
Adjust the Settings:

You can modify the lookback period and multiplier to change the sensitivity of the zones.
Change the colors for the high zone and low zone for better visibility if needed.
Monitor Breakouts:

The script will plot the zones and create labels whenever a breakout occurs, and alerts will trigger when the price crosses the zones as described.
