If the current period's high is above the prior range high and the low use below the prior period's low, then the current period's high-low range will be used as the True Range. This is an outside day that would use Method 1 to calculate the TR. This is pretty straight forward. Methods 2 and 3 are used when there is a gap or an inside day. A gap occurs when the previous close is greater than the current high signaling a potential gap down or limit move or forex previous close is lower than the current low signaling a potential gap up or limit move. The image below range examples of when how 2 and use are appropriate. The Forex equals the absolute value of the how between the current high and the previous close. Average TR equals the absolute value of the difference between the current low and how previous close.

Range rounding can also slightly affect ATR values. ATR is range on the True Range, which uses absolute price changes. As such, ATR reflects volatility as absolute level. In other words, ATR is not shown as a percentage of the current close. This means low-priced stocks will have lower ATR values than high price stocks.
