ATR Stop Loss Calculator
Place a stop at a distance the coin's own volatility justifies, using its live Average True Range — instead of a round percentage that has nothing to do with how it actually moves.
Why a percentage stop is the wrong tool
A 5% stop means something completely different on Bitcoin than on a small-cap meme token. On one it sits outside normal daily noise; on the other it will be hit within hours by movement that carries no information at all. The stop is supposed to tell you your idea was wrong — if ordinary volatility triggers it, it is telling you nothing and costing you a position.
Average True Range measures how far a coin typically travels in a day, including gaps. Setting the stop as a multiple of ATR scales the distance to each asset automatically. A 2× ATR stop is roughly the same statement about every coin: "beyond this, the move is no longer routine".
Choosing the multiple
1× to 1.5× is tight — suitable for short-term trades where you want to be out quickly and accept being stopped often. 2× is the common default and is what most trend-following systems use. 3× is wide, appropriate for position trades you intend to hold through normal pullbacks, at the cost of a larger loss when wrong.
The multiple you choose is not free: a wider stop means a smaller position for the same risk. Use the result here as the stop input on the position size calculator and the two decisions stay consistent.
ATR is not a forecast
It describes recent volatility. When volatility expands — around unlocks, listings, macro events — yesterday's ATR understates today's range. Widen the multiple or reduce size around known events rather than trusting a number computed before them.
Frequently asked questions
What is ATR?
Average True Range, a 14-day average of each day's true range (the greater of high−low, high−previous close, and previous close−low). It measures typical daily movement in price terms, not direction.
What ATR multiple should I use?
Two is the usual default. Use less for short-term trades where you want fast invalidation, more for position trades you intend to hold through pullbacks. There is no universally correct value — it trades frequency of stop-outs against size of each loss.
Should the stop move as price moves?
A trailing ATR stop recalculates from the highest close reached, which is how the Supertrend indicator used elsewhere on this site works. This calculator gives the initial distance; trailing it is a separate decision.
Does this work for short positions?
Yes. Switch the direction and the stop is placed the same distance above the entry instead of below it.
