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.

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).

Bars To Look Back For Highs/Lows:
Candle lookback period for swing high/lows.

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

Trailing Stop Type:
If set to High/Low, the script will use swing lows and highs in its calculation. If set to close, the script will ignore swing lows and highs and give you the distance of the ATR from the current candle close instead. And if set to open, will use the open price.

Show ATR?
This turns on the ATR display.

ATR Color:
You can change the ATR color with this setting.

ATR Location:
This sets where to place the ATR display (bottom right, bottom center, top right, top center).
