Why won't this code run in Pine Script 4? "Undeclared identifier"

Question

Resources are still Pine Script 3 heavy, so I think I'm mixing something up:

I tried to create an Average Daily Range indicator, which is basically the ATR that takes a "D" input no matter what the time frame of the current chart is. My code works perfectly fine on Pine Script 3, but Pine Script 4 throws out the following errors:

line 4: Undeclared identifier `resolution`;
line 6: Undeclared identifier `tickerid`;
line 6: Undeclared identifier `dRange`;
line 8: Undeclared identifier `adRange`

The docs indicate resolution is still an input() argument, and I'm not sure why anything else is called "undeclared".

My full code is:

//@version=4
study(title="Average Daily Range", shorttitle="ADR", overlay=false)

dRange = input(defval="D", title="Daily Range", type=resolution)

adRange = security(tickerid, dRange, rma(tr, 5))

plot(adRange, title = "ADR", color=#000000, transp=0)

What are these "Undeclared identifiers"? And what must I do differently in Pine Script 4 so that I'm getting the same result?

Thank you.

I solved it, but still don't know what "undeclared identifiers" were. I assume it's just Pine's way of saying that dRange violated the new rules with its variable resolution, and that adRange was creating problems with the un-used tickerid, which has been replaced by syminfo.tickerid in PineScript 4.

//@version=4
study(title="Average Daily Range", shorttitle="ADR", overlay=false)

adRange = security(syminfo.tickerid, "D", rma(tr, 5))

plot(adRange, title="ADR", color=#000000, transp=0)
