Introducing Pine Script for coding indicators

Pine Script is Tradingview’s proprietary programming language for creating indicators and strategies directly on the platform. Here are some highlights:

  • Clean, simplified syntax designed for traders
  • Includes common trading functions like moving averages
  • Can access price data, volumes, instrument data
  • Suited for visualizing data on charts
  • Large library of built-in indicators to utilize
  • Free to use with a Tradingview account

Pine Script allows anyone to code their own tools regardless of prior programming experience. It is much easier than traditional languages like Python.

Getting started with Pine Script development

Let’s walk through how to create a simple moving average crossover strategy from scratch on Tradingview using Pine Script:

1. Create New Pine Script

Click the New Script icon in the Tradingview toolbar and give your script a name

2. Import Data

Import any price data you want to use like “close” for closing price

3. Declare Variables

Declare variables for short and long moving average periods

4. Calculate Moving Averages

Add lines to calculate each moving average on the chart

5. Create Trading Signals

Code logic to generate alerts when short MA crosses long MA

6. Add Other Features

Such as colors, styles, plots, etc to improve indicator appearance

7. Troubleshoot and Debug

Fix any errors and confirm indicator behaves as expected

By following these 7 steps you can create a basic custom indicator with Pine Script!

Coding a sample RSI Divergence indicator

Let’s see a real example of building a custom RSI Divergence indicator in Pine Script:

1. Import close price

close = close

2. Calculate 14 period RSI

rsi = rsi(close, 14)

3. Plot RSI

plot(rsi, "RSI", color=#8e1599)

4. Identify RSI divergence

rsi_div = rsi >= rsi[1] and close < close[1] ? 1 : 0

5. Plot Divergence Signals

plotshape(rsi_div, style=circles, color=#2f7ed8, size=size.tiny)

This plots the RSI on a chart and marks circles when RSI divergence occurs. You can extend the code further to refine the Tradingview custom indicator based on your preferences.

Tips for mastering Pine Script

Here are some best practices for learning Pine Script:

  • Review Tradingview Pine Script documentation and guides
  • Start by modifying existing scripts before coding from scratch
  • Recreate simple existing indicators to get a feel for the syntax
  • Use the Pine Editor walk-through on first use
  • Break code into small logical chunks and get each part working before combining
  • Utilize print() statements to output variable values
  • Check console for errors to troubleshoot bugs
  • Use Tradingview community forums if you need help

Take it step-by-step and you’ll be creating advanced indicators and strategies in no time.

Q: What are the basic components of a Pine Script indicator?

A: A basic Pine Script indicator consists of three main parts: the `study` declaration, the input variables, and the logic for plotting the Tradingview custom indicator on the chart. The `study` declaration tells TradingView to treat the script as an indicator, the input variables allow the user to customize the indicator’s settings, and the logic defines how the indicator should be calculated and plotted.

Q: Can I use Pine Script on the TradingView mobile app?

A: While the TradingView mobile app doesn’t currently support writing or editing Pine Script code, you can still use the indicators and strategies written in Pine Script on the mobile app. Simply save your Pine Script code on the TradingView website, and it will be accessible on the mobile app.

However, it’s important to have a basic understanding of trading concepts and technical analysis before diving into Pine Script.

Q: Can I use Pine Script to connect and execute trades on different exchanges?

A: No, Pine Script is not intended for order execution or connecting to external exchanges. Its main purpose is to create custom indicators and strategies on the TradingView platform.
