Bollinger Bands, as defined by John Bollinger, are a technical analysis tool designed to measure market volatility and predict future price movements. The bands consist of three parts: a middle Simple Moving Average (SMA), and two outer lines, which are set at 1.382 and 2.56 standard deviations from the middle line, respectively.

The Function of L1 Dynamic Multi-Layer Bollinger Bands

Now, let's discuss the L1 Dynamic Multi-Layer Bollinger Bands. This is not your ordinary Bollinger Bands; it's a high-tech, modern version with an added layer of L1 magic.
Dynamic Layer: Essentially, it is a moving average line, and of course, you can customize it to any type of moving average you believe performs better. It serves as the backbone of the Bollinger Bands, providing the foundation for our trading strategy. It is the 21-day SMA of the closing price, acting as the central nervous system of our trading operations.
Multi-Layer Structure: The L1 Dynamic Multi-Layer Bollinger Bands also calculate two additional lines, up2 and low2, which are 2.56 standard deviations above and below the middle line, respectively. These extra layers provide us with a stratified perspective on price volatility, offering a more comprehensive understanding of market dynamics.
Color Coding: Don't forget about the color coding! The area between the upper and lower bands is filled with color according to the direction of the price trend. Green indicates an upward trend, while red signifies a downward trend, acting like our eyes guiding us through the labyrinth of trading.

Introduction to Usage

Adding the Indicator: Click the "Add to Chart" button in the Pine-Script editor, and it's like planting the L1 Dynamic Multi-Layer Bollinger Bands on your trading chart.
Interpreting the Bands: The middle line represents the 21-day SMA of the closing price. The upper line is 1.382 standard deviations above the middle line, and the lower line is 1.382 standard deviations below the middle line. These lines act like a safe zone within the territory of wild animals. When the price breaks through these lines, it's akin to wild animals crossing their territory.
Multi-Layer Structure: The script also calculates two additional lines, up2 and low2, which are 2.56 standard deviations above and below the middle line, respectively. These lines are like the offspring of wild animals, providing us with a more stratified perspective on price volatility.
Color Coding: The area between the upper and lower bands is filled with color based on the direction of the price trend. Green signals an "advance" in an upward trend, while red serves as a "red alert" for a downward trend. Like our eyes, it guides us through the maze of trading.

Source Code Analysis

The source code for this indicator is as follows, and I will provide a brief interpretation:
Let me interpret this code for you,
  • This line declares the script's version and defines an indicator named 'L1 Dynamic Multi-Layer Bollinger Bands', abbreviated as 'L1 DMBB'. The overlay=true parameter indicates that this indicator will be overlaid on the price chart.
  • Calculates mid2, which is the simple moving average (SMA) of the closing price over the past 21 days. This will serve as the middle band of the Bollinger Bands.
  • Calculates upper2, the upper band of the Bollinger Bands, which is equal to mid2 plus 1.382 times the standard deviation of the closing price over the past 21 days.
  • Calculates lower2, the lower band of the Bollinger Bands, which is equal to mid2 minus 1.382 times the standard deviation of the closing price over the past 21 days.
  • Calculates up2, an upper band that is further out than the conventional upper band, equal to mid2 plus 2.56 times the standard deviation of the closing price over the past 21 days.
  • Calculates loow2, a lower band that is further out than the conventional lower band, equal to mid2 minus 2.56 times the standard deviation of the closing price over the past 21 days.
  • Defines fillColor based on whether the current mid2 value is greater than the previous value. If mid2 is rising, it uses green; if it's falling, it uses red, with a transparency setting of 80.
  • Plots the mid2 value with a white color.
  • Fills the area between upper2 and lower2 with the defined fillColor, allowing us to visualize the midsection of the Bollinger Bands.
  • Plots the values of upper2, up2, lower2, and loow2 respectively, with upper2 and up2 represented by red lines, and lower2 and loow2 by blue lines.
This code provides traders with a dynamic, multi-layered perspective on market volatility by calculating and plotting Bollinger Bands at different levels. The color coding and multiple layers of Bollinger Bands can assist traders in identifying market trends and potential trading opportunities.
