Range is the difference between high and low in a particular time period, such as a trading day. The range formula is very simple:
Range = High – Low
In Excel, you simply take the cell containing the high and subtract the cell containing the low from it – see screenshot from ATR Calculator below.
Obviously, unlike many technical indicators and other financial calculations, for calculating range you need the history of high and low, not close. Typically you need historical price data in the OHLC or HLC format.
