One of the main advantages of Pine Script is its flexibility. It allows traders to customize their indicators, scripts, and strategies without having to learn a complex programming language. This makes it perfect for both beginner and advanced traders alike. TradingView has designed its own scripting language calledPine Script.It allows users to create custom indicators and run themon our servers. Pine was designed as a lightweightlanguage focused on the specific task of developing indicators and strategies. Most of TradingView’sbuilt-in indicators have been coded in Pine.

Usually, you would provide an expression to a switch statement and evaluate your code against that expression. Otherwise, if condition 2 is true, the script returns value 2. If conditions 1 and 2 return false, the script returns na (null) value. You will see a linearly increasing plot in the output since the value of the persistent_var variable increases with every bar. We will go into the details of indicators and plots in a later section. But first, I will explain the basic building blocks of the Pine Script language.

  1. To enable title names on charts, go to the top right corner of your chart dashboard and click settings.
  2. The finished indicator can be added to the chart, saved for further use and editing, or published in our Community Scripts.
  3. We’ve seen that the security function can be used to display data for stocks not shown on the screen.

The script changes the bar color to red if the time frame of the current chart is in minutes. In the output, you can see that the time frame is in days (D) at the top left corner, which results in a green plot. By following this step-by-step guide, you’ve gained insight into the basics of Pine Script and how to create your own indicators and strategies. Remember that successful trading requires rigorous testing, continuous learning, and adapting your strategies to changing market conditions. The best way to learn Pine Script is by downloading the official TradingView editor.

A Basic Example – Implementing Moving Average Crossover Strategy

Also, in some cases, someone else may have already written the code for what you’re after. Also, you don’t have to spend much time on error checking and handling as TradingView takes care of most of that for you. TradingView has a plethora of data available at your fingertips, ready to access with technical analysis of euro as little as one line of code. In addition, you can find examples of other authors‘ work in our Community Scripts. An extensive number of them are open source scripts that are available to users. If you find yourself stuck on a problem or debugging an issue, don’t hesitate to reach out for help.

Note that the data window shows “My Script” in the upper left-hand corner. This pulls whatever is entered into Line 5 of our code where we declared a name for the indicator. Granted, TradingView has a very comprehensive database of data feeds.

Backtesting Pine Script Strategies

TradingView is great for visualising and developing trading strategies but for execution, in my opinion, we need something more robust. If the markets get busy and TradingView goes down we need our strategies to still execute. The collaboration and industry acknowledgement aspect is why many algorithms which could be successful in specific market conditions are published. There is a community of traders who use TradingView regularly and publishing original work which adds value can be beneficial to the developer and the community.

Building Your First Indicator

So for example if my cryptocurrency portfolio had 1BTC and 20ETH in it I’d add 5 ETH and 0.25 BTC to an exchange like FTX to use as collateral. I’d then use an API to execute a leveraged short position for 1BTC and 20ETH whenever the strategy dictated. My moving average script wouldn’t be approved because there are already a million and one other scripts just like it in the public library. This brings me to an important point about expectations for public work. However when you compare it to a buy and hold strategy which returns over 50% it’s starting to look less optimal.

This one is quite popular as a lot of people use it to plot arrows on the top or bottom of bars to show buy or sell signals. If you’re following along, the screen you’re looking at now is the default starting script to create an indicator. Having an account allows you to save your scripts to the TradingView cloud, and provides the ability to add custom indicators to your charts. If you use alternative data in your strategy, it’s probably easier to use another programming language that offers more flexibility.

Log in to your TradingView account, and in the search bar, search and click the symbol of the security you want to track. This article will show Pine Script examples in the TradingView browser version. If you’d like to try out some of the examples, a one-click download of all the code is available on GitHub. The code will be in text files which can be copied over to Tradingview’s Pine editor.

Inside square brackets, you have to pass an integer value, which refers to the offset in the past. For example, if you want to fetch closing price value two bars in the past, you would use close[2]. If you have sufficient coding skills in any other programming language, skip the following section and jump straight to the “Creating Indicators” section.

We focus on feedback and try to expand the language to meet your needs. You can follow the updates on our release notes page, in the Tradingview chat or in the telegram channel, PineCoders Squawk Box. The finished indicator can be added to the chart, saved for further use and editing, or published in our Community Scripts.

In Pine Script, you may or may not want to mention data types while initializing a variable explicitly. You will see a candlestick chart representing your selected security’s open, high, low, and closing values. TradingView is a website that you can open in the browser of your choice. TradingView also offers a desktop version, which is also technically a browser designed explicitly for TradingView. The last option on the list is a great resource as often another trader might have already coded the indicator or strategy you are after. Overall, there is a lot you can do with Pine script, even though it has certain limitations.
