Display FIBs based on date range?

[xcmsx]

@Everyone,

I have this script that plots FIB retracements automatically based on the high-low of the current chart

https://tos.mx/6WsPiHG
Is it possible to modify and take the high-low from a specific date?,

Example I want to plot retracements from the Max-Week range into my 1day 1 min chart

Thanks
