A stock exchange keeps office hours, while a crypto market keeps trading through the night, the weekend and every public holiday. Most of the time the two schedules never meet. They do meet when a contract that follows a company's share price trades on a venue that never closes. The shares behind it still keep a fixed schedule.
That is where traders get caught out. Company results, inflation figures and deal news often arrive while the stock market is closed. The contract on your screen still shows a moving price. Seeing a price is one thing, though, and being allowed to open a new position at it is another.
Venues that list stock perpetuals usually settle this by splitting the day in two. While the stock's main exchange is in its regular session, you can open, add to and close positions as normal. Outside that session the venue may accept only orders that shrink or close a position. That setting is called reduce-only, and new exposure waits for the next session.
BloFin's contract on Advanced Micro Devices, the AMDUSDT Perpetual, tracks AMD's share price and is listed for trading 24/7 (source: BloFin, AMDUSDT listing notice). Its hours for new positions, and the times when orders may be limited to reduce-only, come from BloFin's rules for all of its stock futures.
What is a reduce-only window on the AMD perpetual?
A reduce-only window on the AMD perpetual is the time when BloFin may accept only orders that shrink or close an AMDUSDT position. That is outside regular weekday trading hours, and on weekends and market holidays. Regular hours match Nasdaq's 9.30AM to 4PM ET session, which is 1.30PM to 8PM UTC until October 30, 2026.
BloFin's stock futures notice sets the rule for every stock contract it lists. Outside regular trading hours on weekdays, and on weekends and public holidays when the relevant markets are closed, trading may be limited to reduce-only orders (source: BloFin, stock futures notice). The word "may" matters. The notice describes a limit BloFin can apply in those hours. So the safe way to plan is to assume a new position can only be opened during regular hours.
The listing notice for AMDUSDT says the same thing from the trader's side. It warns that outside the main market's regular trading hours, the stock may show limited price movement and thin trading. Orders may then be restricted to reduce-only orders for closing positions (source: BloFin, AMDUSDT listing notice). The same warning runs in a banner across the AMDUSDT trading page, so you see it every time you open the contract.
In practice, the window narrows what you can start, while finishing stays open. Say you hold a long AMDUSDT position on a Saturday. You can still sell to close all of it or part of it, and the position stays open in the meantime. What you may not be able to do until Monday's session is buy more, or open a short. The reduce-only flag you can tick on any order works the same way at every hour: it caps an exit at the size of the position you hold. The window simply makes that limit apply to every order on the contract for a while.
The price itself keeps moving through the window. AMDUSDT keeps quoting through nights and weekends, and a position keeps gaining or losing value as it does. How far the price can travel before the next session is the subject of overnight and weekend gap risk on the AMD perpetual.
The live price, the funding rate and the countdown to the next settlement are on the AMDUSDT Perpetual page, next to the same warning banner.
AMD perpetual trading hours in ET and UTC
AMD perpetual trading hours for new positions run from 9.30AM to 4PM ET on weekdays, the same as Nasdaq's regular session. In UTC that is 1.30PM to 8PM while US daylight time lasts, and 2.30PM to 9PM from Monday, November 2, 2026, after US daylight time ends on Sunday, November 1.
The ET times stay fixed, because Nasdaq's regular session is 9.30AM to 4PM ET in every month of the year (source: Nasdaq, stock market holiday schedule). BloFin publishes its regular weekday hours in UTC, as 1.30PM to 8PM in US daylight time and 2.30PM to 9PM in standard time (source: BloFin, stock futures notice). Those UTC times shift by an hour when US daylight time starts or ends. According to BloFin's notice, US daylight saving time finishes at 2AM local time on the first Sunday of November, which falls on November 1 in 2026 (source: BloFin, stock futures notice).
A normal week therefore has 32.5 hours of regular trading: six and a half hours on each of five weekdays. A week has 168 hours, so about four hours in every five fall inside the window, worked out. That share is the same in both halves of the year, because only the UTC labels move.
If you trade from outside the US, convert from UTC rather than from ET, since your own time zone may change on a different date or not at all. Say you live in a country that keeps the same time all year and you usually open positions at 2PM UTC. Until October 30 that is half an hour into the session, and from November 2 it is half an hour before the session opens.
Where AMD's funding settlements fall in the trading day
AMD's funding settles three times a day, at 4PM, 12AM and 8AM UTC, and only the 4PM UTC settlement falls inside regular trading hours. In ET that settlement is at 12PM while US daylight time lasts and at 11AM from November 2, so it stays in the middle of the session either way.
Funding on AMDUSDT is settled every eight hours, starting from 12AM Hong Kong time (source: BloFin, AMDUSDT contract information). Hong Kong time is eight hours ahead of UTC all year, so the three settlements sit at 4PM, 12AM and 8AM UTC in every season. The ET times are what move, by one hour on November 1.
While US daylight time lasts, the 12AM UTC settlement lands at 8PM ET, the end of Nasdaq's after-hours session. The 8AM UTC settlement lands at 4AM ET, the start of its pre-market session. From November 2 they land at 7PM ET and 3AM ET. Both sit inside the window in either season.
That timing matters when you want to avoid a settlement rather than pay or receive it. Closing a position before a 12AM or 8AM UTC settlement is allowed at any hour, because a close reduces the position. Reopening it may have to wait until the next regular session. In daylight time that starts at 1.30PM UTC, five and a half hours after the 8AM settlement. So stepping out of one overnight settlement can mean staying out until the next afternoon, through any price move in between.
Only the 4PM UTC settlement has regular hours on both sides of it, so you can avoid it by closing a position and reopening it in the same session, paying a trading fee on each order. The two overnight settlements offer no such choice, because re-entry after them may have to wait for the session.
AMD perpetual holidays and early closes in 2026
AMD perpetual holidays for the rest of 2026 follow Nasdaq's calendar: Thanksgiving on November 26 and Christmas on December 25 are closed all day, and November 27 and December 24 close early at 1PM ET. On those two days regular hours end at 6PM UTC, three hours earlier than usual.
Nasdaq's 2026 calendar lists those four dates as the last closures and early closes of the year (source: Nasdaq, stock market holiday schedule). BloFin's stock futures notice carries its own 2026 holiday list. For every date left in the year it gives the same days, with the early closes at 6PM UTC (source: BloFin, stock futures notice). Because the four dates fall after November 1, every UTC time on those days is in US standard time.
Day in 2026 | Nasdaq | BloFin regular hours for new positions |
|---|---|---|
Thursday, November 26 (Thanksgiving) | Closed (source: Nasdaq, stock market holiday schedule) | None: closed all day (source: BloFin, stock futures notice) |
Friday, November 27 | Early close at 1PM ET (source: Nasdaq, stock market holiday schedule) | 2.30PM to 6PM UTC (source: BloFin, stock futures notice) |
Thursday, December 24 | Early close at 1PM ET (source: Nasdaq, stock market holiday schedule) | 2.30PM to 6PM UTC (source: BloFin, stock futures notice) |
Friday, December 25 (Christmas) | Closed (source: Nasdaq, stock market holiday schedule) | None: closed all day (source: BloFin, stock futures notice) |
Holidays stretch the window across whole weekends. A normal weekend in standard time runs from Friday's 9PM UTC close to Monday's 2.30PM UTC open, 65.5 hours. Christmas runs from the 6PM UTC early close on Thursday, December 24, to the 2.30PM UTC open on Monday, December 28. That is 92.5 hours, worked out.
Thanksgiving week is shorter still. Regular hours close at 9PM UTC on Wednesday, November 25. Apart from three and a half hours on the Friday afternoon, they open again only at 2.30PM UTC on Monday, November 30. If you hold a position into that week, the Friday session is the only stretch of regular hours between Wednesday night and Monday afternoon, and so your one sure chance to add to it or turn it around.
Say you plan to open an AMD position on Friday, November 27, after your working day ends at 5PM UTC. The session that day runs until 6PM UTC, so you have one hour. An order placed at 6.15PM UTC falls into a window that lasts until Monday afternoon. The same timing applies on December 24.
What reduce-only means for each AMD order type
Reduce-only means an order can only make an existing AMDUSDT position smaller or close it. It never adds to the position and never opens one in the other direction, so in the window, orders that open or add exposure fall outside what BloFin may accept. Orders that close or trim a position stay open to you.
BloFin's own definition is that a reduce-only order will not increase your position size and will not open a new position in the opposite direction (source: BloFin Help Center, reduce-only orders). Each order type you can place on AMDUSDT either fits that definition or it does not, and that decides how the window treats it.
A trigger order, for example, is not live until the market reaches your trigger price, and only then does it send a market or limit order (source: BloFin Help Center, order types). A take-profit or stop-loss set on the whole position works on the same trigger and covers the full size of the position.
AMDUSDT order | In regular weekday hours | Outside regular hours |
|---|---|---|
Market or limit order that opens or adds to a position | Placed and filled in the usual way (source: BloFin Help Center, order types) | Increases exposure, which a reduce-only order never does (source: BloFin Help Center, reduce-only orders) |
Market or limit order that closes or trims a position | Placed and filled in the usual way (source: BloFin Help Center, order types) | A reducing order, with no promise of a fill (source: BloFin Help Center, reduce-only orders) |
Take-profit or stop-loss on the whole position | Closes it with a market order at the trigger, sized to the position (source: BloFin Help Center, TP/SL orders) | Still a closing order, so it fits the reduce-only rule (source: BloFin Help Center, reduce-only orders) |
Trigger order set to open a position | Sends a market or limit order once the trigger price is hit (source: BloFin Help Center, order types) | The order it sends would open a position, the kind the window may block (source: BloFin, stock futures notice) |
Reverse order | Closes the position and opens one of equal size the other way, by market orders (source: BloFin Help Center, order types) | The closing half reduces; the opening half is new exposure (source: BloFin Help Center, reduce-only orders) |
The hardest case is an exit order bigger than the position. On BloFin, the order form takes the amount in AMD. One AMDUSDT contract covers 0.01 AMD, which makes 100 contracts equal to 1 AMD (source: BloFin, AMDUSDT listing notice). Say you hold a long of 0.5 AMD, which is 50 contracts, and you place a sell order for 0.8 AMD, or 80 contracts, with Reduce-only ticked. BloFin's help page works through the same case with a 1 BTC long and a 1.5 BTC sell. The order is only allowed to close the existing position, and it never opens the extra amount as a short (source: BloFin Help Center, reduce-only orders). In your case 0.5 AMD closes and the other 0.3 AMD never becomes a short position.
The same page lists an order larger than the position as one reason a reduce-only order can be rejected (source: BloFin Help Center, reduce-only orders). So the safest exit in the window is one sized to what you hold, checked after any other closing order has filled.
One-way mode and hedge mode outside regular hours
One-way mode and hedge mode change what counts as opening a position outside regular hours. One-way mode gives you a single AMDUSDT position, long or short, which an order the other way reduces. In hedge mode you can hold a long and a short at once, so an order on the other side opens a new position.
BloFin's help page explains the two modes. One-way mode allows a position in only one direction per contract. An order in the opposite direction cancels out or reduces what you hold. Hedge mode lets you hold long and short positions on the same contract at the same time (source: BloFin Help Center, hedge mode).
Take the 0.5 AMD long again, this time during regular hours and without Reduce-only ticked. In one-way mode, a 0.8 AMD sell closes the 0.5 AMD long and leaves you short 0.3 AMD. That flip is what the reduce-only flag exists to prevent. In hedge mode the same sell can be entered as a new short of 0.8 AMD, and you would then hold a 0.5 AMD long and a 0.8 AMD short side by side.
In the window, those two outcomes go different ways. In one-way mode the 0.5 AMD that closes the long is a reduction, while the extra 0.3 AMD would be new exposure. The order that fits the window is one with Reduce-only ticked, sized to the long. In hedge mode, closing the long is a separate order on the long side. Opening the 0.8 AMD short is an opening order, however much you already hold on the long side. If you use hedge mode and want to cut risk overnight, the order to use is the one that closes the long, not one that opens a short against it.
BloFin's page also says the position mode cannot be changed while you have open positions or open orders (source: BloFin Help Center, hedge mode). So the mode you chose before the session ended is the one you keep through the night. Switch it while you hold no position and have no open orders.
AMD after-hours and premarket trading and the perpetual
AMD shares trade in Nasdaq's pre-market session from 4AM to 9.30AM ET and its after-hours session from 4PM to 8PM ET. Both sit outside BloFin's regular hours, so the AMD perpetual may take only closing orders while the shares are still trading in those thinner sessions.
Nasdaq describes those extended hours, 4AM to 9.30AM and 4PM to 8PM ET, as running around its 9.30AM to 4PM ET US trading session (source: Nasdaq, 23/5 trading hub). In UTC, while US daylight time lasts, pre-market trading runs from 8AM to 1.30PM and after-hours trading from 8PM to 12AM. From November 2, both sessions move one hour later in UTC. An after-hours price for AMD is simply the price at which the shares trade in that evening session, and it often moves on news released after the close.
Under the listing notice, the contract's price index is calculated from prices that third-party data vendors quote, and it stays at the last value calculated for as long as outside data is unavailable (source: BloFin, AMDUSDT listing notice). So the price on your screen can keep moving after 4PM ET while the orders you can use have narrowed.
The SEC's investor guide lists the risks of trading in those sessions. They include less trading interest, wider gaps between buy and sell prices, and price moves on company news released outside regular hours (source: Investor.gov, extended-hours trading bulletin). The same pattern shows up on BloFin itself.
BloFin's own AMDUSDT record shows how uneven the hours are. Over the four weeks from September 14 to October 9, 2026, an average half hour of regular weekday hours traded about 2,760 contracts, or 27.6 AMD. The weekday hours of Nasdaq's pre-market session traded about 2,750. The evening after the close, Nasdaq's after-hours session, traded about 490 contracts per half hour, and the weekend about 420, worked out (source: BloFin, AMDUSDT price chart). The quietest stretches for the contract are the evening after the US close and the weekend. Those are also the hours when company news released after the close lands.
Say you are watching when AMD releases news at 4.15PM ET on a weekday and the shares jump in after-hours trading. If you already hold a position, it gains or loses as AMDUSDT follows. You can close it, but into a market trading at under a fifth of its regular-hours pace, worked out. If you hold nothing, a new position may have to wait until 9.30AM ET the next morning, by which time the move may be over.
News that lands outside regular trading hours
The news most likely to move AMD lands outside regular trading hours, when new positions may be blocked. AMD's third-quarter 2026 results come out on November 3 after the market close, and US inflation and jobs figures come out at 8.30AM ET, an hour before the open. To hold a position through those events, open it first.
AMD will report its third-quarter results on Tuesday, November 3, 2026, after the market close, with a conference call at 5PM ET (source: AMD, third-quarter 2026 results date). That is two days after US daylight time ends, so the call starts at 10PM UTC, an hour after BloFin's regular hours end at 9PM UTC. AMD's second-quarter results were published at 4.15PM ET on August 4, 2026, which was 8.15PM UTC, a quarter of an hour into the window (source: AMD, press releases). AMD announced its deal to buy World Labs at 4.05PM ET on September 28, 2026, again minutes after the close (source: AMD, press releases).
Macro releases fall at the other end of the night. September's US consumer price index is scheduled for 8.30AM ET on Wednesday, October 14, 2026 (source: BLS, October 2026 release schedule). In UTC that release lands at 12.30PM, sixty minutes ahead of BloFin's 1.30PM open. The October jobs report follows at 8.30AM ET on Friday, November 6, and the October consumer price index at 8.30AM ET on Tuesday, November 10 (source: BLS, November 2026 release schedule). In standard time both are at 1.30PM UTC, still an hour before the 2.30PM UTC open.
Inflation and jobs figures are among the things that move AMD's price on days with no company news at all. For the perpetual, the timing means the first hour of reaction to every one of these releases happens while new positions may be blocked.
Say you expect AMD's November 3 report to move the stock and want a position through it. The regular session that day ends at 9PM UTC, an hour before the call starts, and after that BloFin may accept only orders that close or trim. Position size and stops for that night are the core of trading AMD around earnings. Once the release is out, the figures to read are the ones in AMD's earnings reports.
Nasdaq's planned 23-hour trading day and the AMD perpetual
Nasdaq plans to add a night session from 9PM to 4AM ET, which would let AMD shares trade 23 hours a day, five days a week. Nasdaq expects the change on Sunday, December 6, 2026, pending the readiness of market data systems and any SEC rule changes it still needs.
Nasdaq's own page sets out the plan. The new session from 9PM to 4AM ET would join the existing 4AM to 9.30AM and 4PM to 8PM ET extended hours. Trading would start at 9PM ET on Sunday and end at 8PM ET on Friday, with a one-hour pause from 8PM to 9PM ET each day. Nasdaq says the move to a 23-hour day is currently expected on December 6, 2026. It adds that the date depends on any SEC rule changes still needed and on the securities information processors being ready. Those are the systems that publish combined market prices (source: Nasdaq, 23/5 trading hub).
In UTC, once US daylight time has ended, the night session would run from 2AM to 9AM UTC. Nasdaq also says its 9.30AM to 4PM ET session will keep setting the main opening and closing prices (source: Nasdaq, 23/5 trading hub).
For the AMD perpetual, the hours that apply are the ones in BloFin's stock futures notice, which gives regular trading hours in UTC that match Nasdaq's 9.30AM to 4PM ET session. Whether BloFin widens those hours once Nasdaq trades through the night is BloFin's decision, and any change would appear in that notice. Until then, a share trade at 3AM UTC on a Tuesday in December would sit in Nasdaq's night session while the same hour stays outside AMDUSDT's regular hours.
Say you hold an AMDUSDT position in December, the night session has started as planned, and AMD announces a deal at 4.15PM ET on a Wednesday. The shares could trade in after-hours until 8PM ET, pause for an hour, and trade again from 9PM ET, which is 2AM UTC. Under the current notice, AMDUSDT would stay outside its regular hours through all of that, until 2.30PM UTC on Thursday. The same planning would apply.
Planning AMD perpetual trades around regular hours
Plan AMD perpetual trades so that every opening decision happens inside regular weekday hours, and set your stops and position size before the window starts. Outside those hours you can still exit, but you may not be able to enter or add, and the market is thinner.
On BloFin, the hours rule covers every stock perpetual, so a routine built for AMDUSDT works for the others too. Say you are setting up a routine for the rest of 2026. Start by converting 9.30AM and 4PM ET to your own time zone for the current half of the year, and mark November 1 and the four holiday dates in your calendar.
Next, decide before 4PM ET whether a position should be held through the night. A position held overnight keeps moving with the contract's price. Set its stop-loss during regular hours, when you can still resize the position if the stop sits too close. A stop can be attached in the same step as the order itself, as in how to trade AMD with leverage on BloFin.
Then size the position for a night you cannot trade into. The arithmetic for choosing a position size on the AMD perpetual starts from how far AMD can move before you can act. Finally, size exit orders to the position you hold, so that a closing order is never rejected for being larger than the position.
Say it is Friday, October 30, the last weekday of US daylight time, and you hold 0.5 AMD long. You can add to it until 8PM UTC that evening. On Monday, November 2, the session opens at 2.30PM UTC, an hour later than the week before, so an order you would normally place at 1.45PM UTC now falls in the window.

Frequently asked questions
How many hours a week can you open an AMD perpetual position?
In a normal week there are 32.5 hours in which new AMDUSDT positions can be opened: six and a half hours on each weekday, from 9.30AM to 4PM ET. The total is the same before and after US daylight time ends on November 1, because only the UTC times move. Holiday weeks are shorter. Thanksgiving week in 2026 has 23 hours, worked out. That is three full days from Monday to Wednesday, nothing on Thursday, November 26, and three and a half hours on Friday, November 27, before the 6PM UTC early close (source: BloFin, stock futures notice).
Is the AMD perpetual open for new positions on Columbus Day and Veterans Day?
Columbus Day and Veterans Day are regular trading days for the AMD perpetual, because Nasdaq stays open on both. The Bureau of Labor Statistics marks Monday, October 12, 2026 as Columbus Day on its release calendar (source: BLS, October 2026 release schedule). It marks Wednesday, November 11 as Veterans Day (source: BLS, November 2026 release schedule). Nasdaq's 2026 calendar has no closure on either date (source: Nasdaq, stock market holiday schedule). BloFin's rule applies on holidays when the markets are closed, so new positions can be opened in regular hours on both days.
Can a reduce-only order on the AMD perpetual be rejected?
A reduce-only order can be rejected or canceled even when you are only trying to close. BloFin lists five reasons. Two are that you hold no position to reduce, or that the order is larger than the position. The others are that the position closed before the order ran, another closing order has already reduced or closed it, or the order would increase exposure (source: BloFin Help Center, reduce-only orders). Even an accepted reduce-only order carries no promise of a fill. A reduce-only limit order fills only if the price reaches your limit and enough orders are waiting on the other side.
Does reduce-only stop an AMD perpetual position from being liquidated?
Reduce-only limits the orders you can place, but liquidation keeps working in the window, because it is triggered by the mark price, which keeps updating. Over the weekend of October 10 and 11, 2026, the AMDUSDT mark price moved in every one of the 48 hours, between 608.47 and 615.63 USDT (source: BloFin, AMDUSDT price chart). A position close to its liquidation price on Friday evening can therefore be liquidated over the weekend, so check your margin ratio before the session ends.
Can you set a stop-loss on the AMD perpetual outside regular hours?
A stop-loss closes a position, so it is a reducing order, the kind BloFin's notice still allows when trading is limited to reduce-only orders (source: BloFin, stock futures notice). One limit matters at night. BloFin says a triggered order priced outside its price limits may fail to fill, in full or in part (source: BloFin Help Center, TP/SL orders). Once the trigger price is reached, a stop-loss on the whole position is placed as a market order (source: BloFin Help Center, TP/SL orders). In thin trading, a market order can fill some way from the price you saw (source: BloFin Help Center, order types).

Nothing in this article constitutes financial advice, and nothing in it is a recommendation to buy, sell or hold AMD in any form. Outside regular weekday trading hours, and on weekends and market holidays, BloFin may accept only orders that reduce an AMDUSDT position, so you may be unable to open or add to a position when news breaks. The contract keeps moving in those hours on thinner trading, an exit may fill at a worse price or not at all, and a leveraged position can still be liquidated. Past performance does not indicate future results. Do your own research and consider your risk tolerance before you trade on BloFin.
