ATR Stop Loss Calculator
Turn an ATR value and multiplier into a long or short stop price.
How it works
Distance = ATR × multiplier. A long stop is below entry; a short stop is above entry. Supply the ATR from your own chart. Fees, slippage and liquidation are separate calculations.

How the ATR Stop Loss Calculator works
This ATR stop loss calculator places an exit a chosen multiple of Average True Range from your entry. Enter long or short, entry price, the ATR value from your chart and a multiplier. The result shows the stop price, price distance and distance as a percentage of entry.
Use ATR from the same instrument and chart
ATR describes the size of price fluctuations. Its value is in price units: if entry is in USDT, supply ATR in USDT too. Use the chart timeframe, lookback period and smoothing method that your strategy specifies. Changing those settings can change the stop even when entry stays the same.
Supply the ATR reading yourself. The inputs here contain one price and one ATR value; historical candles and indicator settings are handled by your chart. A multiplier is a scenario assumption, not an optimized trading parameter.
ATR stop-loss formula and example
Distance = ATR × multiplier. Long stop = entry − distance; short stop = entry + distance. Percentage distance = distance ÷ entry × 100. At entry 100, ATR 2 and multiplier 3, distance is 6: the long stop is 94, the short stop is 106 and the distance is 6%.
Use the stop in position sizing to calculate quantity from an account-risk budget. The ATR calculation gives a price distance and excludes fees, spread, funding and slippage. Check liquidation separately for a leveraged position; a trigger reached after liquidation cannot close that position as planned.
| Entry | ATR | Multiplier | Long stop | Short stop |
|---|---|---|---|---|
| 100 | 2 | 3 | 94 | 106 |
| 100 | 3 | 3 | 91 | 109 |
FAQ
Does this calculator calculate ATR from candles?
Enter the ATR value already calculated by your chart. Keep its instrument, timeframe, period and smoothing settings consistent with your strategy.
Which ATR multiplier should I use?
The calculator evaluates the multiplier you enter. Selecting or validating it needs your strategy's own assumptions and testing; a larger multiplier simply places the stop further from entry.
Is an ATR stop a trailing stop?
This page places a fixed exit relative to the entered entry price. For a trigger measured from the highest or lowest price since activation, use the trailing-stop calculator.
Why is my long stop invalid?
ATR times multiplier must leave a positive stop below entry. Zero, negative, non-finite or numerically indistinguishable prices cannot produce a usable stop.
