Functions that calculate RSI and StochRSI which give the same value as Trading View. I wrote these functions as RSI and StochRSI functions from TA-Lib give different values as TV.

Here are the settings for the chart I am comparing it to.

Did you remove from input: all rows with timestamps who do not have any olhvc value ?

Yes, I am giving only the closing values for the last 120 periods (minutes in this case) I then append the current value every time the function is called.
This is a screenshot of the data that is being fed to the stochastic rsi function.

What should we pass in the series? The OHLC data or just open data?

You need to pass closing series (OHLC 'Close')

I was getting "NaN" as the output when passing in a list of numbers into the StochRSI function until I added the 'min_periods=0' argument to the 'rolling' functions at the bottom. Did anyone else have this problem?

after careful review of ku and binance api candle data i noticed trading view close values , for btc, are 100 to 200 off from both exchange API candle closes vs what TV charts say for the same UTC candles close price....manipulation to give edge against us and make the indicators relying on close values wrong or make the charts give basic traders the wrong idea? ...

You are awesome , this the only code that i had found similar to Trading view.
Thanks

Thank u my friend, Yes u can easily buy one of 2 ways, first u can copy and paste the results in an empty file and read it in excel as csv, second u can import excel helper library that can save the results directly to an excel file.
