Where should you put your stop loss on NQ?
Most stops aren’t wrong, they’re too tight. Here is a simple method, and what nine years of NQ data says about stop placement.
Short answer
Put the stop where the trade idea is proven wrong and outside normal noise, a common starting point is 1.5× the 14-period ATR, then size the position to the stop so the dollar loss is one you can take. Stop placement matters: on NQ from 2017 to 2026, moving the opening-range-breakout stop from the far side of the range to the middle cut the average loss from −$1,335 to −$745 per contract and turned a losing setup into one that held up.
The ATR stop in 3 steps
- Add ATR (14) to your chart. It shows how far price normally moves in one candle.
- Stop = 1.5 × ATR. If ATR is 20 points, the stop goes 30 points away.
- Size to the stop. Risk ÷ (stop in points × dollars per point). $300 risk ÷ (30 pts × $2 per MNQ point) = 5 MNQ contracts.
Wider stop, smaller size, same dollar risk. Volatility picks the stop; your risk picks the size.
What the data says about stops
| Test | Stop | Result (1 NQ contract) |
|---|---|---|
| Opening range breakout | Other side of the range | avg loss −$1,335, worst drawdown −$87k |
| Opening range breakout | Middle of the range | avg win +$2,395, avg loss −$745 |
| 10AM setup | 13 / 20 / 30 points | −$55k / −$67k / −$63k |
Two lessons. A better stop can rescue a strategy with a real edge (the ORB). A wider stop can’t rescue one without an edge (the 10AM setup): it just makes each loss bigger.
Rules that keep stops honest
- Decide the stop before you enter. In real time you have a fraction of a second to resist moving it.
- Never widen a stop once the trade is on.
- On news days (CPI, jobs), be flat before the release or set the stop before the number.
Questions
How do I calculate a stop loss using ATR?
Multiply the 14-period ATR by about 1.5. With ATR at 20 points, the stop goes 30 points from entry. Then size the position so that distance equals the dollar amount you are willing to lose.
How many MNQ contracts should I trade?
Divide your dollar risk by the stop distance times $2 per point. Risking $300 with a 30-point stop is $300 ÷ (30 × $2) = 5 MNQ contracts.
Is a wider stop safer?
Only if you reduce size to match. In our 10AM-setup test, widening the stop from 13 to 30 points without changing anything else made the loss bigger, not smaller.
