What I have in mind is that I would like to have a view of Open Interest data along with the price chart so that alongside chart patterns would also get the view of where the action in Open Interest is happening.

Everyday NSE India provides file which has summary of all the closing prices and F&O data which has details of what I would like to add to the chart.

Is it possible to write a Pine Script code to read from an external file and display this Open Interest data along the vertical axis similar to how volume profile is displayed?

Live reading of Open Interest would be the best scenario but since TradingView doesn’t have F&O data for NSE India, even getting to display previous day’s data would serve the purpose.

I tried looking at the input() function but looks like it either takes the direct data related to an asset class or can be used with data derived after any calculation.. but I am unable to figure out how to use it to access data from external sources.

Thanks

  • Welcome to stackoverflow =) Your question is quite detailed, but it is still a bit hard for us to understand your problem. Share some code, make a minumum example with inputs and outputs.

No it's not possible to import data in Pine scripts other that what is available through TV-supplied feeds. You could enter the values manually in your script's inputs and plot them if you only need a few new values every day.

If you want to import a larger set of values in a series, see this technique.

    A feature that will allow users to create custom feeds for OHLCV EOD data is in the works. That data will need to be created by users, be hosted in a Git repo, and will be accessible from within scripts through a `request.*()` call. – PineCoders-LucF Oct 31 '22 at 15:59

    TV will publish a blog post for it, so you will see it come up in your "What's new" feed on the platform. We also broadcast new Pine Script™ releases in four places. See our broadcast channels at the end of this [blog post](https://www.tradingview.com/blog/en/pine-script-vertical-gradients-33586/). – PineCoders-LucF Nov 13 '22 at 12:05
