There are some indicators on TradingView website that are in pine script and I like to add them to chart library so I have them on my website. But I've done a lot of search, and didn't find how to do that. Any help would be appreciated.

This is on of those indicators that I like to convert to JavaScript:

• javascript
• pine-script

• Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. – Community Bot Commented Oct 20, 2021 at 8:21
• I doubt you can, it’s especially designed to run on their servers “Pine is cloud-based and therefore different in nature to client-side programming languages.” – nanobar Commented Oct 20, 2021 at 8:38

There is no converter for such things. Pine Language has nothing to do with JavaScript, so you will need to write your own implementation for each function.

There is no converter for that. TradingView had provide a way to write custom indicators code using javascript. The guide link is below.

https://github./tradingview/charting_library/wiki/Creating-Custom-Studies

You can write your PineJs logic in javascript easily.

just in case you or someone else is still looking for a solution, I have a library for that exactly. basically it allows you to port pinescript indicators to JS and run them on nodejs or browser.
