Fibonacci Retracement and Target Levels

昨天

Highest and Lowest Price Points:

The script calculates the highest (high_price) and lowest (low_price) prices in the specified timeframe. These values are essential for computing the Fibonacci retracement and extension levels.
Fibonacci Retracement Levels:

fib_0: 0% level (highest price).
fib_236, fib_382, fib_50, fib_618, and fib_100: These are the classic Fibonacci retracement levels used to identify potential support or resistance areas as the price retraces from its highest point.
Fibonacci Extension Levels (Targets):

fib_1618, fib_2618, and fib_4236: These are Fibonacci extension levels used to predict potential price targets in the direction of the trend if the price breaks beyond its current range.
Drawing the Levels:

The line.new function is used to draw horizontal lines on the chart representing the Fibonacci retracement and extension levels.
Dashed lines represent retracement levels.
Dotted lines represent extension (target) levels.
How to Use:
