Markets shut for the break. Financing does not, settlement keeps a calendar of its own, and Sunday night owes nothing to the price you left behind.
Friday evening is a decision that usually gets made by omission
The last hour of a Friday on a desk is mostly admin. Close what was only meant to last the day, look at what is left, decide what stays. Retail accounts skip the third step.
A position still open at the bell was rarely held over on purpose, and no account can tell the difference.
The two states cost different things, which is why the difference is worth restoring. Something opened and shut inside the session pays its way in and out. Something left running pays those, every night of the break, and whatever the market decides while the desk is empty.
The night that gets charged belongs to the provider’s clock
Financing exists because a leveraged position is funded, and funding is priced by the day. Which day is set by a moment each firm picks and publishes rather than by anything happening in a market. Hold a position across your provider’s rollover time and you have carried it overnight for charging purposes. Open and shut either side of that moment on one calendar day and you have not.
So a night is a unit the provider defines, and a Friday spent counting nights is really counting rollovers. Weekend funding cannot land on a Saturday, because nothing settles at a weekend, so it is collected in advance on whichever night jumps the break. In spot currency that is normally the Wednesday, under the two-day settlement convention rather than any decision by your firm.
The tidy Wednesday habit only holds in a week with five working days in it. Add a public holiday and the value dates shuffle along. When the date a roll would settle on is not a good business day for one of the currencies involved, it moves to the next that is, and the extra funding lands on whichever night makes that jump. Thursday, sometimes. Announced on the screen, almost never.
Easter is the awkward one, since Good Friday and Easter Monday sit either side of a single weekend and most European venues take both. The last Monday in August closes London while Frankfurt and New York work. The calendar governing your position belongs to the thing you hold, and both venue and provider publish it in advance.
| The break | What is actually shut | Where the extra funding lands | What settles the answer |
| Ordinary weekend, spot currency | Nothing settles at the weekend | One night, normally the Wednesday | A value date jumping the break |
| Ordinary weekend, UK index | London, Friday teatime to Sunday evening | Commonly each day carried | The provider’s financing terms |
| British bank holiday Monday | London shares and the cash index | Depends on the treatment of a shut underlying | The provider’s published schedule |
| American holiday Monday | US shares, and dollar settlement | Still the Wednesday, carrying four nights | The dollar’s good business days |
| Easter, two holidays around one weekend | Most European venues, twice | Split across two carries | Where Good Friday falls |
| Christmas into the new year | Staggered, venue by venue | Several short weeks running | Each venue’s own list |
Six kinds of break, and where the extra funding lands in each. Treatment of days when the underlying is shut varies between firms, so read this as market convention rather than as any provider’s published schedule.
The reopen owes nothing whatever to the close
All of the above can be settled with a pen and ten minutes. What follows cannot. A market reopening after a break does not resume where it stopped. It resumes wherever buyers and sellers meet, after days in which opinions piled up with nowhere to go. Retail currency quotes generally return on the Sunday evening in Britain, wider than anything on offer the previous week. The distance between Friday’s closing price and the first price you could actually deal at is the gap. It appears on no schedule, and it is the whole weekend arriving in one print.
A gap gets treated as weather, arriving unannounced on a market that happened to be shut. Often it is nothing of the kind. Central banks meet on published dates, statistics offices publish on published dates, and elections are known about for weeks. A fair proportion of long weekends have something already written into them.
That makes Friday an easier job than it looks. Take the days the market will be unavailable to you, open the economic calendar for those specific days, and read what is scheduled inside the window. It cannot tell you which way anything moves. It tells you whether you are choosing to be absent through a quiet stretch or through the one afternoon everybody has had in their diary since March.
Which markets are shut, and which only look shut
A British bank holiday closes the London Stock Exchange, so a position on a UK share or the cash index spends three days on your screen with no underlying market behind it. Currency trades on, since its holidays belong to the currencies rather than to Britain. A few providers keep an out-of-hours quote on selected indices, wider and in smaller size, which is a facility rather than the market coming back.
Two questions are worth putting to your provider in writing before a long break, since both answers live in product terms rather than on the platform. Does financing accrue on days the underlying is closed, and is the out-of-hours quote tradable in your size. One email settles every holiday afterwards.
The one term nobody can put into the sum
Everything chargeable here is countable on Friday afternoon: nights carried, rolls crossed, the rate for the direction you face. The reopen has no rate and no distribution anybody can quote honestly, because long weekends are few and each came with its own news. Anyone telling you what a gap usually costs is describing the ones they remember.
An honest methodology should also say which costs it is badly placed to price, and carry is one of them. A testing account is opened, exercised and closed. Sign-ups get timed, deposits get timed, spreads get sampled, withdrawals get chased, and every item on that list is work done at speed.
Carry is the one charge you incur by doing nothing for a long while, so a programme built to be busy meets it least often. Worth knowing about The Investors Centre before leaning on its numbers: it opens and funds live accounts with its own money to test UK trading platforms, rather than compiling rankings from providers’ published fee schedules, and a fortnight of deliberate activity is a poor instrument for measuring what patience costs.
What the Friday sum actually looks like
Run it in the order that respects what you know. Count the nights, including the extra one the carry collects somewhere in the week, then multiply by the published rate for your instrument in your direction. That is the bill you already agreed to, and the only half that behaves like arithmetic.
The other half yields no figure at all, and the ordinary mistake is to let that settle the weighting. A charge you can compute to the penny feels like the serious one, so Friday gets spent on the financing and none of it on the reopen, when the financing has been the smaller term in almost every episode that ever hurt anybody.
Two questions to answer before you leave the desk
Would you open this, at this size, at nine on Sunday evening, knowing nothing more than you know now? If not, you are carrying it because closing takes effort, and effort is not a thesis.
Then: what will you do if it comes back forty points against you? Decide on Friday, when deciding is free.
Financing is the honest half of a long weekend. Disclosed, calculable, small enough to plan around once you know which night carries it. The reopen is undisclosed by nature, which is why a three-day break deserves a decision rather than a shrug on the way out. The traders still trading a year later were mostly bored on Friday and bored again on Monday.
