Can We Write Code in TradingView? An Introduction to Pine Script

Table of Contents

TradingView began as a proprietary charting and technical analysis platform, but has expanded into much more over time. One common question from advanced traders and quants is – can you write code on TradingView?

The answer is yes! TradingView supports a built-in programming language called Pine Script that allows coders to create everything from customized indicators to fully automated trading systems.

In this comprehensive guide, we’ll provide an introduction to Pine Script, discuss its capabilities, walk through example scripts, examine useful resources, and cover other frequently asked questions. Let’s dive in!

Introducing Pine Script for Coding Trading Tools

Pine Script is TradingView’s proprietary, C-inspired programming language that empowers users to code a variety of trading tools directly on the platform.

With Pine Script, developers can create:

Custom indicators with unique calculations and logic
Automated trading strategies with backtesting
Advanced alerts, scans, and filters

In essence, Pine Script unlocks TradingView’s full customization capabilities for traders with coding know-how.

What Can You Build With Pine Script?

Let’s look at some of the powerful capabilities Pine Script provides:

Indicators – Create customized technical indicators based on math, statistics, machine learning models, external data sources, and virtually any data transform imaginable.

Trading Strategies – Code automated trading systems with entry logic, exit rules, risk management, and comprehensive backtesting and optimization.

Alerts – Program alerts based on indicator values, price action, news events, or any trading criteria using Pine Script.

Scans – Write screening scripts that filter financial instruments dynamically based on technical, fundamental, statistical, or algorithmic filters.

In summary – a whole trading toolkit! Now let’s look at some starter examples.

Starter Pine Script Example 1 – Simple Moving Average

Let’s start with coding a basic Simple Moving Average indicator:

//@version=4
study("My SMA", overlay=true) 
length = input(14)
sma = ta.sma(close, length)
plot(sma, "SMA", color=#FF0000)

This script:

Declares the overlay study with a custom name
Allows setting SMA length via input()
Calculates SMA using the ta.sma function
Plots the SMA line in red color

Just a few lines of Pine gives you a reusable custom indicator!

Starter Pine Script Example 2 – Trading Strategy

We can expand the previous example into a trading strategy:

//@version=4
strategy("My SMA Strategy", overlay=true)
length = input(14)
sma = ta.sma(close, length)

longCondition = close > sma 
if (longCondition)
    strategy.entry("My Long Entry", strategy.long)

shortCondition = close < sma 
if (shortCondition) 
    strategy.entry("My Short Entry", strategy.short)

Now we have basic automated strategy logic including entries. This demonstrates how easily TradingView coders can backtest rules and automate systems using Pine Script.
