The problem with stops that ignore volatility
Plenty of traders use one rule for every stock: “I always put my stop 5% below where I bought.” It's simple, and simple is good. But stocks don't all move the same way. A large, heavily traded bank might move 1% on a normal day; a smaller, thinly traded stock might swing 4% before lunch. A 5% stop is roomy for the first and a hair-trigger for the second.
That's how traders end up being right about the direction and still losing money: the stock dips, takes out a stop that was too tight, then carries on in the original direction without them.
How an ATR stop works
ATR — Average True Range — measures how much a stock typically moves in a day. An ATR stop simply says: “I'll give this trade some number of normal days' movement before I call it wrong.”
stop = entry − (ATR × multiple) for a buy, or entry + (ATR × multiple) for a short.
Take a stock at PKR 240 with an ATR of PKR 6.50. At 1.5× ATR, the stop goes PKR 9.75 below entry, at PKR 230.25 — about 4.1% away. The 1R, 2R and 3R levels follow from that same distance: PKR 249.75, 259.50 and 269.25. A calmer stock with an ATR of PKR 2 would get a much tighter stop, which is exactly the point.
Once you have a stop, size the trade
A wider stop isn't riskier if you buy fewer shares, and a tighter stop isn't safer if you buy more. Risk is stop distance times shares. That's why the button under the result takes your entry and stop straight to the position size calculator, which works out the share count that keeps the loss at your chosen percentage.
A few practical tips
- Sanity-check against the chart. If the calculated stop lands just above an obvious support level, it often makes sense to place it just below that level instead.
- Decide the stop before you buy.Once you're in a losing trade it's very tempting to move it further away “just this once”.
- Stops can move in one direction only. Many traders trail a stop up as a trade works, locking in part of the gain, but never widen it.
Frequently asked questions
What is ATR?
ATR, or Average True Range, is the average size of a stock's daily price range, usually over the last 14 sessions, including any overnight gaps. If a stock's ATR is PKR 6.50, it typically moves about that much in a day. It measures how jumpy a stock is — not which way it's heading.
Where can I find a stock's ATR?
Most charting platforms can add ATR(14) as an indicator beneath the price chart. Stockify's own signal cards size their stops from ATR too, at 1.5 times the value.
What ATR multiple should I use?
Common choices are 1.5× to 3×. A smaller multiple keeps losses small but gets hit by normal noise more often; a larger one gives the trade room to breathe but means a bigger loss per share, so fewer shares for the same risk. Shorter-term trades tend to use tighter multiples, longer swings wider ones.
Is a percentage stop or an ATR stop better?
A percentage stop is simple and easy to stick to. Its weakness is that 5% means very different things for a sleepy stock and a volatile one — too tight for one, too loose for the other. An ATR stop adapts to each stock's normal behaviour. Many traders also check the result against the chart, nudging it just beyond a nearby support or resistance level.
Will my stop always fill at the stop price?
No. A stop becomes an order to sell at the next available price. If a stock gaps down at the open, or hits a circuit limit, you can be filled well below your stop — or not at all until trading resumes. Plan for that by keeping position sizes sensible.
What are the 1R, 2R and 3R targets?
R is the distance from entry to stop. A 2R target sits twice that distance away in the trade's favour. Seeing targets in R makes it obvious whether the upside is worth the risk — check any target against the risk/reward calculator.
