Pine Script is a domain-specific programming language developed by TradingView specifically for creating custom trading indicators and strategies. It's a powerful tool allowing traders to automate their analysis, backtest ideas, and even execute trades (on supported brokers). This tutorial is designed for beginners with little to no prior programming experience. We’ll cover the basics, common concepts, and provide examples to get you started.

What is Pine Script?

Pine Script isn't a general-purpose programming language like Python or Java. It’s tailored for financial markets and focuses on technical analysis. Key features include:

  • **Simplicity:** Designed to be relatively easy to learn, even for those without coding backgrounds.
  • **Built-in Functions:** A wide range of built-in functions for common technical indicators like Moving Averages, Relative Strength Index, MACD, Bollinger Bands, and many more. See Technical Indicators for more information.
  • **Backtesting:** Allows you to test your strategies on historical data to evaluate their performance. Understanding Backtesting is crucial.
  • **Alerts:** You can create alerts based on specific conditions in your scripts.
  • **Visualization:** Easily plot data and indicators on TradingView charts.
  • **Community Scripts:** Access to a large library of publicly shared scripts created by other TradingView users. Explore the Public Library.
  • **Security:** Pine Script is designed with security in mind, limiting access to potentially harmful features.

Getting Started

You don't need to install anything to start using Pine Script. All you need is a TradingView account. Here’s how to begin:

1. **Open a Chart:** Open any chart on TradingView (e.g., BTCUSD, AAPL). 2. **Open the Pine Editor:** At the bottom of the chart, click on the "Pine Editor" tab. 3. **New Script:** Click the "New script" button. 4. **Write Your Code:** The Pine Editor will open, where you can write your Pine Script code. 5. **Add to Chart:** Once you've written your code, click "Add to Chart".

Basic Syntax

Let's look at some fundamental syntax elements:

  • **Comments:** Use `//` for single-line comments and `/* ... */` for multi-line comments.
  • **Variables:** Variables store data. You declare them using `var`. For example: `var price = close;`
  • **Data Types:** Pine Script supports various data types:
   *   `int`:  Integers (whole numbers)
   *   `float`: Floating-point numbers (numbers with decimals)
   *   `bool`: Boolean (true or false)
   *   `string`: Text
   *   `color`: Represents a color.
  • **Operators:** Standard arithmetic operators (`+`, `-`, `*`, `/`), comparison operators (`==`, `!=`, `>`, `<`, `>=`, `<=`), and logical operators (`and`, `or`, `not`).
  • **Functions:** Reusable blocks of code. We'll cover functions in more detail later.
  • **Built-in Variables:** Pine Script provides built-in variables representing price data:
   *   `open`:  The opening price of the current bar.
   *   `high`: The highest price of the current bar.
   *   `low`: The lowest price of the current bar.
   *   `close`: The closing price of the current bar.
   *   `volume`: The volume of the current bar.
   *   `time`: The timestamp of the current bar.
  • **Plotting:** The `plot()` function is used to display data on the chart. For example: `plot(close, color=color.blue);`

A Simple Example: Plotting the Closing Price

Here's a basic Pine Script that plots the closing price of a security:

```pinescript //@version=5 indicator("Simple Close Plot", shorttitle="Close Plot", overlay=true) plot(close, color=color.blue) ```

Let's break this down:

  • `//@version=5`: Specifies the Pine Script version. Always start your scripts with this line. Version 5 is the latest as of this writing.
  • `indicator("Simple Close Plot", shorttitle="Close Plot", overlay=true)`: This line declares the script as an indicator.
   *   `"Simple Close Plot"`: The name of the indicator.
   *   `shorttitle="Close Plot"`: A shorter name for display on the chart.
   *   `overlay=true`:  Indicates that the indicator should be plotted on the main price chart (as opposed to a separate pane).
  • `plot(close, color=color.blue)`: This line plots the closing price (`close`) in blue (`color.blue`).

Understanding Indicators

Indicators are calculations based on price and volume data that help traders identify potential trading opportunities. Pine Script makes it easy to create and customize indicators.

Let's create a simple moving average (SMA) indicator:

```pinescript //@version=5 indicator("Simple Moving Average", shorttitle="SMA", overlay=true) length = input.int(title="SMA Length", defval=20) sma = ta.sma(close, length) plot(sma, color=color.red) ```

  • `length = input.int(title="SMA Length", defval=20)`: This line creates an input option for the user to specify the length of the SMA.
   *   `input.int()`:  Creates an integer input.
   *   `title="SMA Length"`: The label displayed next to the input field.
   *   `defval=20`: The default value for the input (20 periods).
  • `sma = ta.sma(close, length)`: This line calculates the SMA using the `ta.sma()` function.
   *   `ta.sma()`:  The built-in function for calculating the Simple Moving Average.
   *   `close`: The source data (closing price).
   *   `length`: The length of the SMA (defined by the user input).
  • `plot(sma, color=color.red)`: This line plots the SMA in red.

Strategies and Backtesting

Pine Script allows you to create trading strategies and backtest them on historical data. A strategy defines the rules for entering and exiting trades.

Here's a simple strategy that buys when the price crosses above the 20-period SMA and sells when it crosses below:

```pinescript //@version=5 strategy("SMA Crossover Strategy", shorttitle="SMA Cross", overlay=true) length = input.int(title="SMA Length", defval=20) sma = ta.sma(close, length)

longCondition = ta.crossover(close, sma) shortCondition = ta.crossunder(close, sma)

if (longCondition) 

   strategy.entry("Long", strategy.long)

if (shortCondition) 

   strategy.entry("Short", strategy.short)

```

  • `strategy("SMA Crossover Strategy", shorttitle="SMA Cross", overlay=true)`: Declares the script as a strategy. The `strategy()` function is used instead of `indicator()`.
  • `longCondition = ta.crossover(close, sma)`: Checks if the closing price crosses above the SMA. `ta.crossover()` returns `true` when the first argument crosses above the second argument.
  • `shortCondition = ta.crossunder(close, sma)`: Checks if the closing price crosses below the SMA. `ta.crossunder()` returns `true` when the first argument crosses below the second argument.
  • `if (longCondition) strategy.entry("Long", strategy.long)`: If the `longCondition` is true, enter a long position.
   *   `strategy.entry()`:  Enters a trade.
   *   `"Long"`:  A unique identifier for the trade.
   *   `strategy.long`:  Specifies a long (buy) trade.
  • `if (shortCondition) strategy.entry("Short", strategy.short)`: If the `shortCondition` is true, enter a short (sell) position.
   *   `strategy.short`: Specifies a short (sell) trade.

To backtest this strategy, simply add it to the chart and open the "Strategy Tester" tab at the bottom of the screen. You can adjust the backtesting parameters (start date, end date, initial capital, commission, etc.) to evaluate the strategy's performance. See Strategy Tester for more details.

Functions

Functions are reusable blocks of code that perform specific tasks. They help to organize your code and make it more readable.

Here's an example of a custom function that calculates the percentage change between two values:

```pinescript //@version=5 indicator("Percentage Change Function", shorttitle="Pct Change", overlay=false)

// Custom function to calculate percentage change calculatePercentageChange(value1, value2) => 

   (value2 - value1) / value1 * 100

// Example usage percentageChange = calculatePercentageChange(close[1], close) plot(percentageChange, color=color.purple) ```

  • `calculatePercentageChange(value1, value2) => ...`: Defines a function named `calculatePercentageChange` that takes two arguments, `value1` and `value2`. The `=>` symbol is used to define the function body.
  • `(value2 - value1) / value1 * 100`: The formula for calculating percentage change.
  • `percentageChange = calculatePercentageChange(close[1], close)`: Calls the function with the previous closing price (`close[1]`) and the current closing price (`close`).
  • `plot(percentageChange, color=color.purple)`: Plots the calculated percentage change in purple.

Advanced Concepts

  • **Arrays:** Used to store collections of data.
  • **Matrices:** Used to store two-dimensional arrays.
  • **Security Function:** Allows you to access data from other symbols or timeframes. Understanding the Security Function is essential for intermarket analysis.
  • **Alert Conditions:** Create alerts based on specific conditions in your scripts. See Alerts for more information.
  • **Requesting Data:** Accessing external data sources.
  • **Repainting:** A critical concept to understand when backtesting. See Repainting for details.
