In Pine Script, grouping comments is done by creating multi-line comments or adding comments on each line of code to explain blocks of logic. Pine Script allows for both single-line and multi-line comments, but it does not support block comments in the traditional sense like some other programming languages (e.g., /* */ in JavaScript).
Here’s how you can add grouped comments in Pine Script:
1. Single-Line Comments
Use // to add a comment on each line. You can group your comments by placing related comments on consecutive lines.
// This section of the code calculates the moving averages
ma_short = ta.sma(close, 9) // 9-period moving average
ma_long = ta.sma(close, 21) // 21-period moving average
// The following code checks for crossover
bullish_crossover = ta.crossover(ma_short, ma_long) // Bullish signal
bearish_crossover = ta.crossunder(ma_short, ma_long) // Bearish signal
2. Multi-Line Comments
Use /// for a multi-line comment. Each line of the comment must begin with ///.
/// This strategy is designed to identify bullish and
/// bearish crossovers using short and long moving
/// averages. The crossovers are used to generate
/// buy and sell signals.
3. Grouping Code with Comments
You can group related code blocks with a combination of single-line and multi-line comments to make your script more readable.
// Moving Averages Calculation
/// We calculate two moving averages:
/// 1. A short-term 9-period moving average
/// 2. A long-term 21-period moving average
ma_short = ta.sma(close, 9)
ma_long = ta.sma(close, 21)
// Crossover Logic
/// The following section checks for crossovers
/// between the short and long moving averages.
/// A bullish crossover occurs when the short MA crosses
/// above the long MA, and a bearish crossover occurs
/// when the short MA crosses below the long MA.
bullish_crossover = ta.crossover(ma_short, ma_long)
bearish_crossover = ta.crossunder(ma_short, ma_long)
Summary
- Single-Line Comments (
//): Use these for short, inline comments or for grouping multiple lines of comments together. - Multi-Line Comments (
///): Use these when you need to write a longer, multi-line comment to explain a section of your code. - Group Your Code: Use comments to clearly group related sections of your script, making it easier to understand and maintain.
By carefully organizing your comments, you can make your Pine Script code much easier to read and understand, especially when working on complex strategies or indicators.
