# ATR Trailing Stop Indicator

I rely on this script for both my live trading and my backtesting process. I couldn’t live without it. It’s extremely simple – all it does is calculate your trailing stop price.

If you like this indicator then you might also like my ATR By Time indicator which calculates the current ATR based on the trading session / time of day instead of recent price action:

## How It Works

The first number in blue is the current ATR (pips). The second number in green is your trailing stop loss price for Long trades, and the third number in red is your trailing stop loss price for Short trades.

For short trades, the stop loss price is calculated by adding the current ATR value to the highest-high of the given lookback period.

For long trades, the stop loss price is calculated by subtracting the current ATR value from the lowest-low of the given lookback period.

## Settings

ATR Length:
ATR period (how many candles to include in the calculation).

Use Structure?
If set to true, the script will use swing lows and highs in its calculation. If set to false, the script will ignore swing lows and highs and give you the distance of the ATR from the current candle close instead.

How Far To Look Back For High/Lows:
Candle lookback period for swing high/lows.

ATR X ?:
This controls your ATR multiplier. For example, if you want to use a 2x ATR stop, set this to 2.
