Average Daily Range (ADR) Calculation
I understand that the Average Daily Range is calculated over several days where each day's range (hi - lo) is averaged.
Can someone explain to me what people mean when they say Weekly ADR or Monthly ADR or 180day ADR? How is it calculated?
e.g. Does Weekly ADR = last week's ADR of the week's 5 trading days?
I have seen many people use these terms including people talk about yearly ADR but have so far never seen a rule that defines how it should be calculated.
Any help is explaining would be well appreciated.
