What is the daily rollover gap in forex?
Updated 3 November 2026 · 5 min read
If you watch a forex chart for more than a day, you will eventually see it: a small jump in price at the same time every day, with no news and no market closure to explain it. That is the daily rollover gap, and it is a routine part of how forex brokers run their books, not a sign that something went wrong with your data feed.
Why a gap can appear with no market closure
Forex trading does not pause overnight the way a stock exchange does. Instead, once a day, your broker performs a rollover: every position still open is technically closed and reopened at the next value date's rate. According to IG's published explanation of forex rollover, this happens at 5:00 p.m. New York time for US-dollar pairs, the same anchor used for the weekly Friday-to-Sunday close. Because the position is closed and reopened rather than left untouched, the closing rate and the reopening rate do not have to be identical. That small difference is what you see as a jump on the daily candle.
This is a different mechanism from a weekend gap. On a weekend, the whole market shuts for roughly 48 hours, so any news or order flow during that time only gets priced in once trading resumes, which is why weekend gaps can be large. A rollover gap has no closure behind it at all, just the bookkeeping moment, so it is normally far smaller. For the broader picture of how and why forex gaps form in general, see What is a forex gap, and why do most gaps fill?
Why Wednesday looks different
If you track your account's swap or rollover charges, you will likely notice Wednesday is not like the other four weekdays. Spot currency trades normally settle two business days after the trade date. To keep that schedule consistent across the weekend, brokers following standard FX convention book three days of rollover interest on Wednesday instead of one, as described in IG's rollover guide. The same source notes that before a market holiday, an extra day's rollover is typically applied two business days ahead, for the same settlement reason.
That triple charge affects your swap cost more than it changes the shape of the gap itself, but it is worth knowing if you are trying to explain why Wednesday's candle or your account statement looks different from the rest of the week.
A worked example
Say GBP/USD closes a 4:59 p.m. New York candle at 1.2650. At 5:00 p.m., your broker's system closes every open GBP/USD position at that rate and reopens them at whatever the next quoted rate is, say 1.2648. On your chart, the candle that opens at 5:00 p.m. starts two pips away from where the previous one closed. Multiply that pattern across all your open pairs and every trading day, and you have the daily rollover gap: a small, routine jump tied to a fixed clock time rather than to news.
What GapEdge data shows
GapEdge is built to track the larger gaps that form when the market has actually been shut, principally the weekend reopen in Gold, EUR/USD and GBP/USD, not the small daily rollover jump described here. Since Dec 2025, GapEdge has tracked 94 gold gaps around the weekly open; 100.0% of them filled, with a median time to fill of 50m. You can see every one of those gaps, filled or not, in the Gap Explorer. For the mechanics of that weekly gap and its exact UTC timing, see What time does the forex market open on Sunday?
How GapEdge helps
If a rollover-sized jump is easy to confuse with the start of a real gap, GapEdge's push alert tells you which is which: it only fires when Gold, EUR/USD or GBP/USD actually gaps at a session open, with the zone and size included, so a routine 5:00 p.m. rollover tick does not get mistaken for a tradable event.
Common mistakes
- Treating every daily jump as a tradable gap. Most are the routine rollover difference described above, not a market dislocation.
- Assuming the rollover clock matches your local time zone. It is anchored to New York time and shifts with US daylight saving, the same way the weekly open does.
- Confusing the Wednesday triple-rollover charge with a bigger price gap. It is a swap-cost rule, not a change in how the price itself moves.

Questions traders ask
What time does the daily rollover happen in forex?
For US-dollar pairs, rollover is anchored to 5:00 p.m. New York time, the same clock used for the weekly open and close. Your own broker's server may stamp a different clock time on the candle, so check your platform's own stated time if you need the exact minute.
Why does my chart show a small gap every day at the same time?
At rollover, your broker technically closes every open position and reopens it at the next value date's rate. Those two prices do not have to match exactly, and the difference is what shows up as a small jump on the daily candle.
Is the daily rollover gap the same as the weekend gap?
No. The weekend gap follows a full market closure from Friday to Sunday, so days of news and order flow can be priced in at once. The daily rollover gap happens every trading day with no closure at all, just a technical close and reopen, so it is normally far smaller.
Why is Wednesday's rollover different?
Spot forex trades normally settle two business days later. To account for the weekend, brokers book three days of rollover interest on Wednesday instead of one, under IG's published rollover rules. That is a swap-cost effect, not a separate type of gap, but it is the one day where the rollover charge itself is visibly larger.
Does the rollover gap happen on weekends or holidays too?
No new rollover happens while the market is shut. Before a market holiday, brokers typically apply an extra day's rollover two business days ahead of time, the same way they do for the Wednesday weekend adjustment.
Can I avoid the rollover gap?
You cannot avoid the rollover itself if you hold a position through 5:00 p.m. New York time, since it applies to every open position on the broker's book. Being aware of the schedule just means the jump will not surprise you if you are watching the chart at that moment.
