Need help to code the indicator so it can display the levels in the past not just tod

Hi there,

Is there any code that can calculate the levels (example pivot, fibs, camarilla) and plot those levels in the past but not just today.

I have found an indicator that gives proprietary level but only for today but I'd like it to plot the levels in the past so I can backtest, and is there anyway to configure so it can also give me the option to plot the levels in 2 weeks, 300 days etc so the levels will be plot accordingly.

Any idea guys?

Thanks!
