Trading View Pine Script Syntax Error Explained

Trading View Pine Script is a programming language specifically for creating and customizing tradingview charts and strategies. However, the syntax of the language can be difficult, and a beginner might quickly get overwhelmed trying to learn it. A particularly vexing problem is the syntax error at the input ‘[’ – fortunately, this article will explain the issue and how to fix it!

The Problem

The syntax error at the input ‘[’ occurs when a person writes or inputs a script in Pine Script but doesn’t follow the syntax of the language correctly. This results in an error at the point where the script has been written incorrectly. It’s important to note that Pine Script requires a high level of control and precision when writing code, as even a simple bracket can cause major issues. Moreover, it’s important to make sure that the syntax used is up-to-date, as the language continually evolves.

How to Fix It

Fortunately, fixing the syntax error is relatively straightforward. First and foremost, it’s recommended that the user double-checks their code for any issues. This should be done multiple times, as errors can often be missed at first glance.

If no issues are found, then it may be recommended to look for the most up to date version of Pine Script. The syntax of the Pine Script changes over time, and old versions will not be able to interpret the script correctly. Therefore, it’s important to make sure the version is updated.

Additionally, the user might consider making use of a professional-grade code editor. This will give the user a number of helpful features such as syntax-highlighting and the details of any errors that may have occurred.

Finally, the user can attempt to re-write the script entirely. This may be an arduous task depending on the nature of the script, but it will likely guarantee that the syntax is correct. As the language is constantly evolving, it’s important to make sure the syntax is up-to-date.


The syntax error at the input ‘[’ in Trading View Pine Script is a common issue that can easily be fixed by double-checking the script and code for any issues. If this doesn’t work then the user should consider using the most-recent version of Pine Script as well as a high-grade code editor for a clear view of the script’s errors. Finally, re-writing the script entirely may be the only solution to ensure the accuracy of the script’s syntax. This article has hopefully provided insight into the syntax error at the input ‘[’ in Trading View Pine Script and how it can be fixed!

Understanding Trading View Pine Script Syntax Error at Input ‘[‘

Trading View Pine Script is a programming language for creating automated trading strategies on Trading View, a popular online platform for traders. It is designed with the specific purpose of making it easier for traders to quickly develop and test trading strategies with millions of potential combinations, and then apply them in live trading. However, when using Pine Script, traders must be aware of potential errors that can arise when coding, including the syntax error at input ‘[‘ message.

What Is Pine Script and How Does it Work?

Pine Script is a programming language designed to help traders create trading strategies on Trading View. It uses simple code that is easy to read and allows traders to create and test strategies with millions of possible combinations. For example, a trader who wants to create an automated trading strategy to buy a stock when it crosses a certain price level can write code in Pine Script with that specific logic. Then Trading View can run the script to see what happens when different parameters (i.e. different price levels, different indicators, etc.) are used.

What is Syntax Error at Input ‘[‘?

The syntax error at input ‘[‘ is an error message which appears when a trader is trying to run a Pine Script strategy but has mis-typed the code. This error is caused by not using the correct syntax when coding in Pine Script, such as forgetting to use a comma when defining a range, or forgetting to include a parameter in a function. This can be an easy mistake to make, but it is important to be aware of what can cause it so that you can fix it quickly and continue testing your strategies without having to start from scratch.

How to Fix a Syntax Error at Input ‘[‘

The first step in fixing a syntax error at input ‘[‘ is to look back at the code to see if anything looks wrong. A common mistake is forgetting to add a comma after a parameter or missing a semicolon at the end of a line. Once you have found the mistake it is best to fix it, so that the code will work properly. Once you have done this, you can re-run the code and see if the error message appears again. If it does, then it is likely that you have not fixed the mistake, or that you have made a new one. It is important to go through each line of the code carefully to identify any other mistakes that may be present.

Once you have fixed all of the mistakes, the syntax error at input ‘[‘ message should no longer appear and you will be able to run the code successfully.

In conclusion, creating trading strategies on Trading View using Pine Script can be a great way to develop automated trading systems quickly. However, as with any programming language, it is important to be aware of potential errors, such as syntax error at input ‘[‘ message. By understanding how this error can be caused, and how to fix it, traders can ensure that their strategies are running properly and that they are not making any mistakes that can lead to costly trading losses.
