What Happens at the Daily Rollover

There is a minute each day when nothing on the chart has changed and your account has. The position you opened this morning is the same size, the price is roughly where it was, and yet a line has appeared in your history that was not there before — a small charge, occasionally a small credit — and on some nights a stop you placed with room to spare has been filled at a price the chart barely touched.

Both of those come from the same event: the daily rollover, the point at which your broker ends one trading day and starts the next. It happens every weekday, at the same clock time, and most traders learn about it one surprise at a time rather than all at once.

The rollover is the one hour of the day that costs you money whether or not price moves.

This article follows on from our piece on why the hour belongs in your trading record. The rollover is the most concrete example of that argument, because what changes at that hour is not a matter of interpretation — it is printed in your broker's contract specifications and in your own statement.

What the rollover actually is

Spot forex and spot metals are, in principle, contracts for delivery a short time after the trade. Retail accounts never deliver anything, so instead of settling, the broker rolls every open position forward to the next day at the end of each trading day. That roll is where the overnight financing is applied, and it is why the moment has a name.

Where the day ends is a convention, not a law of nature. Many brokers anchor it to the late afternoon in New York, which is why so many platforms run their server clock a few hours ahead of London — it makes the rollover land at midnight on the server. Yours may differ. The only reliable source is your own broker's specification page, and the only reliable clock is your platform's server time.

The first cost: the quote widens

Around the rollover, liquidity is at its thinnest point of the day. The New York session has wound down, Asia has not properly started, and the institutions that provide prices to your broker are themselves rolling positions and repricing. The practical result is that the spread — the gap between the price you can buy at and the price you can sell at — widens, sometimes to several times its normal size, for a few minutes either side of the roll.

Nothing about this is hidden. Watch your platform's quote across that window once or twice and you will see it. What catches people out is not the widening itself but what the widening does to orders that are already resting.

Why a stop can fill when the chart says it should not have

Most charts draw the bid. A long position's stop is a sell order, and it triggers on the bid — so for a long, what you see is roughly what you get. A short position's stop is a buy order, and it triggers on the ask, which is the bid plus the spread. When the spread widens sharply at rollover, the ask can reach a short's stop while the bid-drawn chart shows price nowhere near it.

Afterwards the chart looks innocent and the fill looks like a broker error. Usually it was neither: the order did exactly what it was told, on a price your chart was not drawing. If you want to see this for yourself, most platforms can display the ask line alongside the bid — turn it on and watch the two separate at the roll.

The same widening affects entries. A pending order that triggers during the roll is filled at whatever the wide quote allows, and a market order sent in that window pays the widest spread of the day for no reason other than timing.

The second cost: financing

Every position still open at the rollover is charged or credited for being held overnight. In currencies, the figure reflects the difference between the interest rates of the two currencies in the pair, adjusted by your broker's own markup. On metals it reflects a financing rate the broker sets. In both cases the amount is a function of your position size and the number of nights, not of what the price did.

Two details are worth knowing before they show up in a statement.

• The charge is usually not symmetrical. The markup is applied to both sides, so it is common for one direction to cost noticeably more than the other earns, and for both directions to cost something. Whether that is true of the instrument you trade is on your broker's specification page, listed as a long swap and a short swap.
• One night a week counts for more than one. Because of how settlement dates fall around weekends, one weekday rollover is charged for several nights at once — often the middle of the week for currencies. Which day, and how many nights, varies by broker and instrument, so check rather than assume.

For a trade held for an hour, none of this matters. For a trade held for a week, it can be a meaningful share of the result — and unlike the spread, which you pay once, financing accumulates for as long as the position is open.

What to do about it

The rollover is not something to fear or trade around at any cost. It is a scheduled event with known effects, which makes it one of the easier things in trading to plan for.

• Find the rollover time in your platform's server clock and write it down. Everything else here depends on knowing when it is.
• Avoid sending market orders in the few minutes either side of it. If a setup fires then, a limit order at your price is almost always the better instrument.
• If you hold shorts through the roll, look at where your stop sits relative to the ask, not just the chart. A stop placed only a spread's width beyond a level is the one most exposed to the widening.
• Before holding a position for several days, look up the long and short swap for that instrument and multiply by the nights you expect to hold, remembering the extra-weighted night. If the number surprises you, better now than on the statement.
• Record it. Add a column to your log for whether a trade was open across a rollover, and another for the financing it paid. It is the cleanest example of a cost that belongs to the hour rather than to the idea.

Common questions

Is the rollover the same time at every broker?

No. The convention of anchoring it to the New York afternoon is widespread but not universal, and daylight saving moves it against your local clock twice a year even when it stays fixed on the server. Treat any time you read online, including anything implied here, as a starting point to verify against your own platform.

Can I avoid the swap by closing before the roll and reopening after?

You avoid the financing and pay the spread twice instead — once to close and once to reopen — and the reopening happens at exactly the hour the spread is widest. For most positions that trade is worse than simply paying the swap. It is worth doing the arithmetic for your own instrument before building a habit around it.

What about swap-free accounts?

Some brokers offer accounts without overnight financing, usually replacing it with a fixed fee, a wider spread, or a limit on how long positions can be held. The cost has moved rather than disappeared, so compare the terms against what the swap would have been for the way you actually trade.

Does the spread widening matter if I only use limit orders?

Less, but not to zero. A resting limit to buy fills on the ask, so a wide quote can reach it at the roll just as it can reach a short's stop — and whether a fill at that moment is a good one depends on why price got there. A fill caused by a temporary widening is not the same as a fill caused by the market moving to your level.

Why we published this

We publish free calls on Telegram with entry, stop and target, and we post the outcome of each one afterwards. Some of those calls are still open at the rollover, and a reader following them pays that night's spread and financing at their own broker, on their own terms — which our posted outcome cannot see and does not include.

So the honest thing is to say it plainly: the result we post is the price path, and the result in your account is the price path minus costs that depend on your broker and your timing. The rollover is the largest of those costs that you can know in advance. Knowing it is how you read anyone's track record, ours included, in the terms that will actually apply to you.
