You set a stop with a sensible cushion, went to make dinner, and came back to a closed trade at a loss. The chart shows a quiet minute at 5pm New York time and a price that has already drifted back above your level. The stop did not need the market to reach it, it needed the spread to widen, and the rollover hour is when spreads are at their worst.

Rollover is the hour the FX day changes hands

Spot forex runs around the clock, but a trading day still needs a boundary. In its article When FX futures pause, CME Group says its FX futures trade nearly around the clock with a 60-minute maintenance break each day from 4:00 to 5:00 p.m. Central time, which is 5:00 to 6:00 p.m. New York time. Listed FX futures do not trade in that hour. Most retail FX and CFD platforms keep quoting.

On the spot side, the same moment is when the value date rolls. CME describes it this way: positions held through 5:00 p.m. New York time are carried into the next settlement date, overnight financing is applied and banks close one book and open another. Brokers anchor their own financing cutoff there too, for example OANDA's financing examples count a position as held overnight only if it is open at 5pm ET. We covered that fee side in how forex triple swap works. This post is about what happens to your stop around it.

Liquidity thins and the quote gets wider

According to CME, most professional participants would rather cross that hour flat. Bank desks reduce risk into their book close, pricing engines widen risk parameters and many liquidity providers scale back or step away. CME's own wording is that the result is often the least liquid hour of the FX day, and it adds that this is not misconduct, because making prices when few counterparties are active is more expensive.

Retail brokers feel it twice. Clients expect to trade, so the broker keeps quoting, but its own hedging options shrink: bank liquidity is thin and the listed futures market is shut. CME's description is that the rational response is to keep quoting but wider, and that a spread of a fraction of a pip in liquid hours can grow to several pips through rollover and considerably more on less liquid crosses.

A stop triggers on one side of the quote

CME is direct about the mechanism: stop-loss orders are typically triggered on one side of the quote, a long position on the bid and a short position on the ask. The spread itself can therefore decide whether a stop is activated. We went through the general case in why a stop can hit when price never touched it. Brokers say the same thing about floating spreads in general: FxPro's FAQ states they can widen considerably before and after high-impact news and during high volatility. Rollover is the quiet-hours version of the same effect, and CME's account of it is the clearest one I found.

Here is a hypothetical with made-up numbers. You are short a currency pair with a stop at 1.2740. During the rollover hour the mid-price sits at 1.2732, 8 pips below your stop. The spread jumps from under a pip to 20 pips, so the ask moves to 1.2742, which is half the spread above mid. The ask is through your stop, the order triggers, and the mid-price never went near it.

CME's article contains a similar worked example for a long EUR/USD position, where a spread widening from half a pip to 18 pips takes the bid through a stop 8 pips below mid. It also points out that a triggered stop generally becomes a market order, so the fill can add slippage on top of the spread that set it off.

The arithmetic generalizes if the spread widens evenly around mid, which is a simplification. The stop fires when half the spread exceeds the distance from mid to stop.

Stop distance from mid	Spread that triggers it
5 pips	more than 10 pips
10 pips	more than 20 pips
15 pips	more than 30 pips

Whether your pair and your broker ever reach those spreads at 5pm is a question about your own platform, and the table cannot answer it. It only shows that tight stops sit closest to the edge.

Nobody can check the price in that hour

For roughly one hour there is no listed FX price at all, as CME points out, so whatever appears on a retail platform is the provider's own construction. You have no public benchmark to compare it with, at the exact moment spreads are most variable.

CME also raises the A-book and B-book split. Many providers internalize part of their client flow, meaning the provider is the counterparty. In that case a stop triggered by the provider's own widened quote is, mechanically, the book's gain. CME says no intent is required for that to be true, and that regulated brokers are required to price fairly and many hedge substantial parts of their flow. The difficulty it names is observability, not proof of bad behavior. Check your broker's order execution policy to see how it describes its own pricing and hedging.

A stop is a bet that nobody will quote wide while you are away. At 5pm New York, quoting wide is the default.

Time zones move the hour around on your clock

The break is fixed to New York time, so it moves on a European clock. In normal alignment 5pm in New York is 23:00 in Berlin. For the few weeks when US and European clock changes disagree, the gap between your local time and New York shifts by an hour and it lands at 22:00 instead. Many platforms show server time rather than your local time, so look at the timestamp on your stop fill and convert it before you decide it was random.

What a trader might do with this

None of this is a recommendation to place a particular stop, but the options CME lists are worth knowing.

• Know your trigger. Find out whether your platform fires stops on bid, ask, last or mid, and whether that changes during rollover.
• Check the history. Look at your platform's quote or tick history for 5pm New York over several weeks and note the widest spread for your pair, not the average.
• Consider a mid-based exit. Some platforms let you configure the trigger side, and algorithmic traders sometimes code a synthetic stop that watches the mid-price. CME notes that the fill still crosses the spread and that a synthetic stop depends on connectivity, but a spread spike alone cannot set it off.
• Respect the window. CME's suggestion is to avoid leaving tight stops in place into 5:00 p.m. or to be flat through the hour.
• Size for the worst quote. If a position has to be held through the close, plan for the widest spread you have observed in that pair at rollover.

Stop placement is a separate question from all of this, and it deserves its own logic, such as a volatility-based multiple instead of a round number. If you are still working out what a stop should do for you in the first place, start with what a stop loss is and how to set it.

● FAQ

Why do forex spreads widen at 5pm New York time?

That is when the FX trading day rolls over. CME Group describes it as the least liquid hour of the FX day, because bank desks reduce risk into their book close and many liquidity providers scale back or stop quoting. Brokers that keep quoting through it widen the spread to cover the cost of making prices when they cannot easily hedge.

Can a stop loss trigger if the chart never reaches it?

Yes. A long position's stop is checked against the bid and a short position's stop against the ask. If the spread widens enough, the bid can drop onto your long stop or the ask can rise onto your short stop while the mid-price stays well clear of the level.

Is a stop hit at rollover a sign my broker is cheating?

Not by itself. A widened spread explains the trigger without any intent, and CME says as much in its own article. What you can do is check your platform's quote history for that minute, compare it with other days, and find out which price side your stop uses.

Do futures traders have the same rollover stop problem?

Not in the same form. CME's FX futures pause for a 60-minute maintenance break from 5:00 to 6:00 p.m. New York time, so no stop can trigger while the book is closed. The risk moves to the reopening, because if news hits during the pause the market can open at a different level and a stop can still fill worse than expected.

How wide a stop survives the rollover spread?

If the spread widens evenly around the mid-price, your stop fires once half the spread is bigger than the gap between mid and stop. A stop 10 pips from mid needs a spread of more than 20 pips to trigger that way. Check your own platform's history to see how wide that pair actually gets during the hour, and treat that figure as a floor for planning, not a forecast.
