RSI value - One period rate of change

I am reading Street Smarts book and came across a strategy named momentum pinball which uses RSI as indicator. The author asks to plot 3 days RSI with one period rate of change. What is one period rate of change in here?

Book says:
“Plot a three-period RSI of a one-period rate of change (the daily net change). We refer to this as an LBR/RSI.”

I can’t find period rate of change in Zerodha charts or Tradingview charts. Please help me to understand this.
Thank you!

I think You are looking for Price Rate of Change [1] on a daily Time frame…this is available in Kite…

PS :- if you want to create scanner, Rate of Change is also available on Chartink
