The Average True Range (ATR) is useful in measuring the strength of a trend. For example, if the market's price makes a big move or reversal, either Bullish or Bearish, there will be an increase in volatility which leads the ATR to rise. We can also use ATR to set Stop loss on a trade, to do this normally a number equal to 3 times the ATR number will be added to the high price range on short positions or will be deducted from lower range price in long positions.
