stock - ( Tradingview - Camarilla) Show last two day's lines only

Question

This script plots camarilla on tradingview chart. There is a toggle option to "Show last periods". When I enable it, it will show lines all the way back. I just need it to show current and previous day.. (or specify how many days historical lines is better).

Picture from another script that contains what I need.

Tried but could not modify. Thanks in adance!!
