Tradingview Pine Script Indicator coding

Tradingview Pine Script request Looking to have an indicator in Pine Script that has two inputs: Start_Number = input(3, minval=1, step = 1, title="Start_Number") End_Number = input(41, minval=1, step = 1, title="End_Number") The output would be the average RSI using the PRIME NUMBERS between the start number and end number. To keep the code clean, would like the calculation of RSI to be done in a function and have the ability to be used in Higher Time Frame.
