ATR — the average true range
ATR answers one question: how much does this market actually move? That single number is the foundation of volatility-aware stops, targets, and position sizing.
ATR — the average true range, explained.
ATR (Average True Range) is a volatility indicator that measures how much an asset typically moves in one period. It averages the 'true range' — the greatest of high minus low, high minus previous close, or previous close minus low — over a lookback window, 14 periods by default.
The 'true' in true range matters: by comparing against the previous close, ATR captures gaps and limit moves that a simple high-minus-low range would miss. The result is an honest, direction-blind measure of movement — ATR says nothing about whether price is going up or down, only how violently it travels.
That makes ATR less a signal generator and more a calibration tool. A stop-loss placed a fixed percentage away means something completely different on a calm pair than on a volatile one; a stop placed at 2× ATR adapts automatically. The same logic applies to profit targets, trailing distances, and position sizes — which is why ATR shows up inside so many otherwise unrelated strategies.
From idea to a running bot.
Bots lean on ATR wherever a distance or size needs to scale with volatility.
Volatility-scaled stops
Instead of a fixed percentage, place the stop a multiple of ATR below entry — wide enough to survive normal noise on this specific market, tight enough to cap damage when the trade is wrong.
Adaptive targets and trails
Profit targets and trailing stops set in ATR multiples stay proportionate: they expand in wild markets and tighten in quiet ones, without hand-tuning per pair.
Regime awareness
Rising ATR flags expanding volatility (breakouts, panic); falling ATR flags compression. Strategies can trade differently — or stand aside — depending on the reading.
Built for the way you trade.
ATR is for anyone who has to decide where a stop or target belongs.
Risk managers
ATR turns 'how far can this wiggle before I am wrong?' from a guess into a measurement, which is the starting point of defensible stop placement and position sizing.
Multi-pair traders
A rule expressed in ATR multiples transfers between pairs with wildly different volatility, where a fixed-percentage rule silently changes its meaning.

Frequently asked questions.
What does an ATR value actually tell me?
That the asset has recently moved about that much per candle, on average, including gaps. A 500-dollar ATR on a 60,000-dollar asset means roughly 0.8% typical movement per period on that timeframe. It says nothing about direction.
How do traders set stops with ATR?
A common pattern is entry minus a multiple of ATR — for example 2× ATR below entry for a long. The multiple controls the trade-off: wider survives more noise but risks more per trade. It is a parameter worth backtesting rather than copying.
Is a high ATR good or bad?
Neither — it is information. High ATR means bigger typical moves: more opportunity per trade and more risk per mistake. Strategies should scale stops, targets, and position sizes to it rather than judging it.
Can I use ATR in VolatiCloud strategies?
Yes. ATR is one of the 27 built-in indicators in the visual strategy builder, usable in conditions alongside RSI, moving averages, and the rest — and every rule you build with it can be backtested on real data first.
