ATR Trailing Stops
ATR Trailing Stops (ATRTS) identifies exit points for long and short positions. First, an exponential moving average (EMA) of the input is taken to determine the current trend. Then, the Average True Range (ATR) is calculated and multiplied by a user defined factor. If the EMA is increasing (uptrend), the ATR product is subtracted from the price or, if the EMA is decreasing (down trend), it is added to the price, and along with a few details the ATRTS is formed. The user may change the position (long), input (close), method (EMA), period lengths, percent factor and show entry option(see trading signals below). This indicator’s definition is further expressed in the condensed code given in the calculation below.
How To Trade Using ATR Trailing Stops
ATR Trailing Stops are designed to aid in exit decisions. For long positions, if the price is less than the ATRTS a sell signal is generated. Conversely for short positions, if the price is more than the ATRTS a buy to cover signal will be given. The user may also chose to show entry signals, however they should only be used with a trend filter.
