Where to Put a Stop Loss in Forex Trading

Put the stop past the price that proves the trade idea wrong, with a gap drawn from how far that instrument normally moves, then let the distance decide the position size.

What that is in pips depends on the pair, the chart and the day, which is why no borrowed figure travels. Published distances run from 14 pips to 110 and ATR multiples from 1x to 5x.

Where do you put a stop loss?

At the invalidation level: the price at which the reason you took the trade stops being true. Not at a sum of money you are willing to lose, and not at a round number.

Traders Second Brain puts it in one line: "A stop belongs where the trade thesis becomes invalid, while position size belongs to the distance between entry and that stop." It adds a caution: "Structure is not proof that price cannot trade there. It is the point where this strategy no longer wants the position."

Putting the stop past the level rather than on it is the second half, because a stop sitting exactly on the obvious swing low is sitting where everyone else's is. Ticker Daily puts a figure on the gap: "Place your stop 0.5-1% below support, not at it".

Four units are in circulation, which is why published answers look contradictory: a fixed pip count, a percentage of price, a multiple of ATR, and a chart level plus a buffer. The last one is the method here; the others are shortcuts to it.

How many pips should a stop loss be?

There is no pip number that travels. What the published figures rest on:

Source	Distance published	Where the number comes from
tradethatswing.com	45, 67.5 and 90 pips	1x, 1.5x and 2x ATR on one EURUSD short, with the daily chart named and the ATR reading given
tradingpedia.com	25 pips	A running EUR/USD example, "a stop-loss 25 pips below the opening price and a take-profit 50 pips above it". No timeframe
litefinance.org	20 pips	An input field rather than a recommendation. It lists three units instead of one distance: a size in currency, a number of pips, or a predetermined closing price
marketmates.com	110, 103 and 14 pips	110 from a $100 risk on a 10,000-unit USD/JPY position, 103 from a support level at 160.00, and 14 from a 2 x ATR rule where the ATR reading is "seven"

That last row shows the trap. The 14-pip figure names no pair, no timeframe and no unit for the seven, on a page that has just explained why that matters: "not all pips are worth the same, depending on the currency you are trading", and "this system does not work well across different currency pairs".

tradethatswing.com supplies the conversion, tying every figure to a named instrument and chart: "if you are day trading the USDJPY on a 5-minute chart and the ATR is 0.08, that means the price is moving about 8 pips (from high to low) every 5 minutes". The swing case comes separately: "If you are swing trading the daily EURUSD chart and the reading is 0.0045, that means the price is moving about 45 pips per day, on average." Read any pip figure against that and it turns back into a statement about one pair on one timeframe.

Do you put the stop below the swing low?

Below it, with a buffer. Colibri Trader combines the two: "find your logical stop level using support or a swing low. Then, subtract a multiple of the ATR (like 1.5x or 2x ATR) from that price". Trading with Rayner anchors to the level rather than the entry: "If you are long from Support and have a multiple of 1, then set your stop loss 1ATR below the lows of Support".

It only becomes testable if you define the level before you need it. Traders Second Brain is blunt about the word "beyond": on its own it decides nothing. Write down which swing or bar you mean, which edge of a range, what price has to print to trigger the order, and how much buffer sits past it. So do not pick a different swing after the trade, and do not call the nearest visible line support.

How wide should the volatility buffer be?

Most published rules use a multiple of ATR, and they run from 1x to 5x.

• apptrading.ai: "A practical baseline is 1.5× to 2.5× ATR(14) for swing trades, then adjust the multiple to the timeframe and structure"
• theindicatorlab.com, by holding period: scalps 1 to 1.5x ATR, swing trades of two to ten days 2 to 3x, position trades 3 to 5x
• tickerdaily.com: 2.5 to 3x ATR as a baseline stop width, and 3 to 4x for high-volatility names
• tradealgo.com: 1x, 1.5x, 1.5-2x, 2x, 2.5x and 3x ATR all on one page
• crosstrade.io: structure first, never tighter than a 1x ATR floor

One source separates the multiple by instrument class, and that is the shape worth copying: apptrading.ai gives forex majors 1.2x to 2.0x ATR, large-cap stocks 1.5x to 2.5x, crypto majors 2.0x to 3.5x and small-cap names 2.5x to 4.0x. Set that beside the 2.5-3x baseline on an equities page and the mismatch is exact, because the equities floor sits above the whole forex band.

A multiple is not a distance until you say which instrument and timeframe the ATR was read on. Traders Second Brain turns that into a procedure, "Freeze the instrument, bar interval, ATR lookback, sampling time, and multiplier before reviewing results", and adds: "A popular multiplier is not evidence for your strategy." In ChartLabs an ATR is a Pine Script sample you can open in the editor, so its period and smoothing are yours to set and to write down.

What is a tight stop loss, and why does a tight stop get hit?

A tight stop is one placed inside the market's normal movement, so ordinary noise reaches it before the idea has had a chance to be wrong. Trading with Rayner states the test: "your stop loss should be wide enough to accommodate the daily swings of the market". theindicatorlab.com puts numbers on both edges: 0.5x ATR from entry is "placing a stop inside the noise", 5x ATR away means the structure is too far or the volatility too high to trade cleanly, and 1.5 to 3x ATR is where it considers the two to agree.

The explanation you meet most often is stop hunting, and the sources disagree about it. Ticker Daily says institutions "hunt these levels with temporary spikes" and Colibri Trader that "large institutional players know exactly where clusters of retail stop orders are sitting". LiteFinance calls that a conspiracy theory, "just a supposition based on a feeling rather than on an objective fact". Traders Second Brain sets an evidence bar: a claim about "stop hunting" needs order-book and venue evidence, because a wick through an obvious level does not show who caused it. The placement rule is the same either way.

Costs make a tight stop worse than it looks. tradethatswing.com raises fills: "Even if a stop loss is placed, there is no guarantee that we will be able to get out at the price we specify". It names the gap in the next line: "Getting a different price than expected is called slippage." On a 14 or 20 pip stop, spread and slippage are a large share of the distance.

Can you set a stop as a percentage?

You can, and it is mostly a habit from equities, where a percentage of price is stable across a share's life. It means something quite different on a currency pair.

tickerdaily.com publishes percentages throughout, 5 to 9% below entry for mid-cap growth and 9 to 20% for high-volatility momentum, with its worked ATR example at 8.2% below entry on a US share. tradethatswing.com's 2x ATR on daily EURUSD is 90 pips, which on a pair near 1.1525 is roughly 0.8% of price. Same multiple, two markets, nothing in common.

Traders Second Brain allows a percentage stop in one case only: "percentage distance only when it is a tested instrument-specific rule". That matters while you read around, because several of the guides on stop placement are not about forex at all, and a number lifted from an equities or crypto page has changed session and gap behaviour before you place a trade.

Does the stop decide the position size, or the other way round?

The stop decides the size. Every source that mentions both puts them in that order, and reversing them is how risk becomes accidental.

Colibri Trader names the error: "The single biggest mistake I see traders make is deciding how many shares they want to buy before they even know where their stop loss should be. When you do it that way, your risk is completely random." Traders Second Brain draws the consequence precisely: "Moving a stop closer to make the size affordable changes the thesis rule. Keeping the stop and reducing size preserves it."

That is how the ChartLabs order bar works. A risk percentage control sizes the position from your stop distance, so you set the share of the account you are prepared to lose. Market, limit and stop orders all carry stop-loss, take-profit and risk-reward in the same bar.

To work the arithmetic outside a chart, our position size calculator takes the stop distance in pips as its input.

How do you find the distance your own setup needs?

Step the setup bar by bar and record, for every trade, where the idea was actually invalidated and how far that was from your entry. Then check how often a narrower distance would have been hit by a move that went on to work.

Almost none of the published guidance says how, which is odd given how many print a number. apptrading.ai gets nearest to a procedure with its diagnostic, that if the average win is small relative to the rest of the results the multiple may be too tight, checked over 30 to 50 trades. Traders Second Brain adds the condition for any such check, that "the backtest and live rule use the same bar construction and session".

ChartLabs replays historical charts one bar at a time, so you place the trade as the bars arrive rather than reading the outcome off a finished chart. Costs are applied per symbol, so a distance that only works before costs shows up as one that does not: commission and slippage are modelled on the trade, and the Trading Costs card reports Total Costs, Cost Drag and Avg Cost / Trade. Our forex backtesting guide makes the related point about spread on low timeframes.

Record per trade the instrument, the timeframe, the distance and the unit, the volatility reading if the unit was a multiple, and whether the stop was hit before the idea failed. That last field tells you whether the distance was wrong or the setup was. A Notes column in the Orders panel and a note button on the chart carry it, notes come through in the CSV export, and tags let the analytics be filtered afterwards. Charts remember your timeframe per symbol too, which matters because the unit depends on the chart.

Then run the same setups at one distance and again at another, and compare the same numbers both times. Writing the rule down first is the point our beginner's guide makes about stops.

What goes wrong?

Widening the stop after entry, which is the one instruction none of these sources contradicts. Ticker Daily: "Never move a stop wider after entry", adjusting size before entry instead. tradethatswing.com: "Once you place an ATR stop loss, stick with it. Don't expand it if volatility expands." Traders Second Brain: "Do not recalculate the stop from a later ATR value unless the strategy explicitly defines trailing behavior." Moving a stop the other way, towards your entry once a trade is working, is a separate decision with its own arguments.

Last, believing a comparison that was never tested. Claims that one placement method outperforms another turn up without a sample, a period or an instrument behind them, so none is repeated here, and we publish no comparison of our own.

Where to start

Pick the unit your setup implies, write the distance rule down before you enter, and step enough trades to see whether the stop was hit before the idea failed or after. One plan, $20 a month or $200 a year, with a 7-day free trial and no credit card required: start the free trial.
