Almost every beginner asks the same question after their first few stopped-out trades: where should my stop loss actually go? Too tight and normal price wobble takes you out just before the move you predicted. Too wide and one loss does real damage. This guide shows you where to put a stop loss using a repeatable process, not a feeling.
The one-sentence answer
Put your stop loss at the price where your trade idea is proven wrong — then size the position so that hitting it costs an amount you have already accepted.
Everything below is detail on those two halves. Notice what is not in that sentence: "a fixed number of pips", "wherever keeps the loss small" or "I'll decide later". Those are the three habits that quietly empty beginner accounts.
Why "proven wrong" matters more than "how far"
A stop loss is not a pain threshold. It is the point at which the reason you entered no longer exists.
Say you buy because price has pulled back to a support level and printed a strong bullish candle. Your idea is: buyers are defending this area. If price trades decisively back through that area, buyers clearly were not defending it — your idea is invalid. That is where the stop belongs.
If you instead place a 10-pip stop because "10 pips feels safe", you are putting your exit somewhere the market has no reason to respect. Normal fluctuation can hit it while your idea is still perfectly valid.
Four sensible ways to place a stop loss
1. Beyond market structure (the default)
For most beginner setups, structure is the clearest guide:
- Long trades: below the most recent meaningful swing low, or below the support zone you are buying from.
- Short trades: above the most recent meaningful swing high, or above the resistance zone you are selling from.
"Meaningful" means a swing that is visible without squinting — one that clearly turned price. If you need to zoom into a one-minute chart to find it, it is probably not the level that matters. Our guide on how to draw support and resistance levels covers marking these zones properly.
2. Add a buffer — don't sit exactly on the level
Levels are zones, not laser lines. Price frequently pokes a little beyond an obvious low before turning. If your stop sits exactly on the low, it is sitting where many other traders' stops are too.
A small buffer beyond the zone gives the trade room. How much depends on the instrument and timeframe — which is why many traders use a volatility measure for it (next point).
3. Volatility-based stops (ATR)
The Average True Range (ATR) is a standard indicator showing how far an instrument typically moves per candle on your chosen timeframe. Some traders place their stop a fraction of one ATR beyond structure, or use a multiple of ATR as the whole stop distance.
The benefit: your stop automatically widens when markets are wild and tightens when they are quiet, so you are not using a summer-holiday stop during a central bank announcement.
4. Time stops
Not every stop is a price. A time stop says: if this trade has not started working within X candles or by a set time, I close it. It is useful for intraday traders whose setups depend on momentum arriving quickly.
Don't forget the spread
On a short trade, your stop is triggered by the ask price, but most charts display the bid. That means a sell trade can be stopped out even though the bid price on your chart never quite touched your stop — the spread did it. This is most noticeable around market open, rollover and news, when spreads widen.
Practical fix: on short trades, add the typical spread to your buffer. And check the spread on your platform at the time of day you actually trade.
Stop placement and position size: always in this order
This is the part that turns stop placement from guesswork into risk management:
- Find the invalidation level on the chart.
- Measure the stop distance from your entry.
- Calculate the position size so that, if the stop is hit, you lose your pre-decided risk — commonly 1% or less of the account.
A wider stop means a smaller position. A tighter stop means a larger one. The money at risk stays the same either way. If this is new to you, read how to calculate position size — it is the formula that makes this work.
If the correct stop is so wide that even the smallest position size would risk more than you are comfortable with, that is not a reason to tighten the stop. It is a reason to skip the trade.
Five stop loss mistakes beginners make
- Choosing a fixed pip stop for every trade. Markets do not move in your favourite number. Let the chart set the distance.
- Placing the stop where the loss "feels" small. Comfort is not analysis. A stop inside normal noise is a donation.
- Moving the stop further away when price approaches it. This is the single most expensive habit in trading. The stop was set when you were calm; you are now not calm.
- No stop at all ("I'll watch it"). Platforms freeze, internet drops, news hits. A mental stop is not a stop.
- Moving to breakeven too early. Tightening to entry the moment a trade goes slightly positive often converts a good trade into a scratch. Only trail a stop according to a rule you wrote in advance — for example, behind each new swing once a new structure forms.
What about guaranteed stops?
Some UK brokers offer a guaranteed stop loss order (GSLO). A normal stop becomes a market order when triggered, so in a fast market or over a weekend gap you can be filled at a worse price than your stop — this is called slippage. A guaranteed stop closes you at exactly your level regardless, usually for a fee charged only if it is triggered. Check your broker's terms; they are worth understanding before major news or holding over weekends.
A simple stop placement checklist
Before you enter, you should be able to answer yes to each:
- I can point to the exact level that proves my idea wrong.
- My stop sits beyond that level with a buffer (plus spread on shorts).
- I've sized the position so hitting the stop costs my planned risk.
- My target gives a reward that justifies the risk (see risk-reward ratio explained).
- I've decided in advance whether and how I'll move the stop.
Frequently asked questions
How many pips should a stop loss be?
There is no correct fixed number. The right distance is whatever the chart says — the space between your entry and the point where the setup is invalid. On a 5-minute chart that might be a few pips; on a daily chart it might be over a hundred. Position size adjusts so the money risked stays the same.
Should I always use a stop loss?
For leveraged products like CFDs and spread bets, trading without a stop means a single bad move or price gap can do outsized damage. A hard stop on the platform is the most basic form of protection you have.
Why does my stop loss keep getting hit before price reverses?
Usually because the stop is sitting exactly on an obvious level with no buffer, inside normal volatility, or (on shorts) the spread is triggering it. Widen to beyond the structure, reduce position size to compensate, and check the spread at your trading time.
Is it ever OK to move a stop loss?
Moving it closer to lock in risk according to a pre-written rule is fine. Moving it further away to avoid taking a loss is not — it changes the risk you agreed to after the trade is already going against you.
What's the difference between a stop loss and a stop order?
A stop loss closes an existing position to limit a loss. A stop entry order opens a new position when price reaches a level. Both become market orders when triggered (unless guaranteed), so both can slip in fast markets.
Key takeaways
- Put the stop where your trade idea is invalid, not where the loss feels comfortable.
- Use structure plus a buffer; consider ATR to adapt to volatility.
- Remember the spread on short trades.
- Stop first, then position size — never the other way round.
- Never widen a stop once you are in the trade.
