The formula for calculating the RSI value given in varsity & kite chartiq/tradingview is the same as given below.

I have taken reliance 1-year daily OHLC data in excel and verified the RSI values, calculating with the above formula, It’s matching with kite tradingview/chartiq.

You can check this google spreadsheet for your reference.

In varsity, the calculation is shown for the first RSI value with the simple average.
In excel calculation for RSI 14, we lookup avg of the first 14 gain/loss values and For the second RSI value we take( previous avg * 13 + present avg gain/loss ) /14, this gives like smoothed average value.
