Weekend gaps and crypto's 24/7 market: why prices jump and what that does to your stop-loss

Plenty of traders close out on a Friday with a stop-loss in place and expect it to cap their loss. Then they log in on Sunday evening or Monday morning and find the stop filled well past its level, or the account already hit by a margin close-out. That jump is a weekend gap.

This guide covers why gaps form in forex and stock indices, why crypto behaves differently, and how gaps interact with stop-loss orders, leverage and broker protections. It is general education, not advice on any trade.

What a weekend gap actually is

A gap is empty space on a chart between one bar's close and the next bar's open. No trades happened at any price in between.

In forex, a weekend gap is the jump between the last price before the market closes on Friday and the first price when it reopens on Sunday evening, New York time. Nothing trades at the broker in between, so news from the weekend is priced in at once.

The world doesn't stop because a market is closed. Elections, central bank comments, geopolitical events and policy announcements can all land on a Saturday. When trading resumes, the first price reflects everything that happened while nobody could trade.

Why forex gaps even though it's a "24-hour" market

Forex is often called a 24-hour market, and on weekdays it nearly is. But it is not truly open all the time. Retail forex normally pauses from late Friday to Sunday evening.

The usual convention is that forex closes at 5pm New York time on Friday and reopens at 5pm New York time on Sunday. There is no single official bell, though. Spot forex trades across many venues rather than on one exchange, and each broker publishes its own hours. Check your own broker's schedule rather than assuming.

One useful way to think about it: the forex "close" is really the banks of London and New York stepping back, not a physical exchange closing. When the big dealers step away, nobody is making continuous prices for retail platforms.

Two things drive the size of a Sunday gap:

• New information. If weekend news changes what traders think a currency is worth, the reopening price moves to reflect it.
• Order imbalance and thin liquidity. If weekend news is negative for a currency, more traders want to sell at the open than buy at Friday's prices. On top of that, liquidity is often thin at the Sunday open, which can mean wider spreads and jumpy pricing.

Most weekends are quiet and the gap is small or barely there. The risk comes from the uncommon weekend when something big happens.

Why stock indices gap, and more often

Stock index gaps work the same way, but they happen more often because cash equity markets close every night as well as at weekends. Index futures and broker index CFDs may trade for long stretches outside the cash session. Even so, weekend closures leave a period when nothing trades at all.

Index gaps are driven by:

• Overnight and weekend news: macro data, policy decisions, geopolitical events.
• Company news: earnings or guidance released outside trading hours can move heavily weighted index members, and the index with them.
• Other markets reopening: when Asian or European markets reopen after a shock, the index you trade may reprice at its own open.

If you trade an index CFD, your broker usually prices it off an underlying futures market. Your gap risk follows that market's hours, not the hours of the stock exchange itself. Your broker's contract specifications will show when the instrument actually trades.

How crypto differs: no weekend close

Crypto spot markets don't close. Crypto is decentralized — no central institution needs to be open. Bitcoin trades in the middle of a Sunday night just as it does on a Tuesday afternoon, so a single crypto exchange's chart doesn't show the structural Friday-to-Sunday gap you see in forex.

That doesn't remove gap risk. It changes its shape in three ways.

1. Crypto absorbs shocks while other markets are shut

When a big story breaks late on a Friday, crypto is often the main liquid market still open to react. Leveraged traders feel that first.

A clear recent example: crypto's derivatives markets forcibly closed over $19 billion in positions held by 1.6 million traders on Oct. 10, 2025. The trigger came late in the day. At 20:00 UTC, a broad-based sell-off swept across global markets following U.S. President Donald Trump's announcement of a proposed 100% tariff on imports from China. Crypto was carrying heavy leverage, with open interest near all-time highs and a buildup of crowded long positions. Prices then cascade[d] through tightly clustered stop-loss and liquidation zones - amplifying the downward move.

The liquidations ran in roughly 24 hours across Oct. 10-11. The total comes from reported exchange data, mainly CoinGlass, and one analysis cautions that liquidation totals should not be interpreted as $19 billion of investor cash disappearing directly. Either way, it showed how fast a weekend-adjacent shock can move through a market that never closes.

2. 24/7 doesn't mean continuous liquidity

A market can be open and still have very few resting orders. Reviewing the October crash, one analysis noted that the crash exposed how thin crypto order books can become under stress. Roughly $7 billion in positions were liquidated in under one hour during this peak panic, according to the same source.

When order books are that thin, price can skip levels during a fast move even though the market never closed. To a stop-loss order, that looks a lot like a gap.

3. Crypto products on traditional venues used to gap, and some still can

Regulated crypto futures used to follow traditional exchange hours, which created the well-known weekend "CME gap" on bitcoin futures charts. While the futures market was shut, traders then had to manage the gap between where futures last closed and where spot prices had wandered.

That changed when CME Group launched 24/7 crypto futures and options on Friday, May 29, 2026, with only a single weekly maintenance window. Weekend activity has been growing. As of October 2026, crypto weekend trading at CME Group reached $1.3 billion in notional volume, and average daily weekend volume climbed 55% from September to a record $340 million.

Some crypto-linked products still trade only during stock market hours, such as exchange-traded funds or shares of crypto-related companies. Those can still open Monday at a very different price from Friday's close if crypto moved over the weekend.

How gaps interact with stop-loss orders

This is the part that costs people the most money.

A standard stop-loss is not a guaranteed exit price. The US SEC explains that when the stop price is reached, a stop order becomes a market order, and that the stop price is not the guaranteed execution price for a stop order. In its words, the execution price an investor receives for this market order can deviate significantly from the stop price in a fast-moving market where prices change rapidly.

A gap is the extreme version of a fast market, because there are no prices at all between Friday's close and the reopening. So a stop at a level inside the gap triggers on the first available price, which may be far beyond it. Normal stops become market orders at Sunday open, executed at the first available price — which may be far from your stop level if there is a gap.

Stop-limit orders: a price cap, but no promise of an exit

A stop-limit order converts to a limit order instead of a market order. According to the SEC, an investor can avoid the risk of a stop order executing at an unexpected price by placing a stop-limit order, but the limit price may prevent the order from being executed.

In a gap, that trade-off matters. If price opens beyond your limit, the order may not fill, and you stay in a losing position that can keep moving against you. Neither order type stops a gap from happening. Each just handles it differently.

Also note that different brokerage firms may have different standards for determining whether the stop price of a stop-limit order has been reached. Some trigger on bid or ask quotes, others on last trade. Your broker's order documentation is the final word.

Leverage turns gap risk into account risk

On a small, leveraged account, a gap can be the difference between a planned loss and an empty account.

A hypothetical worked example

These numbers are hypothetical and rounded to keep the arithmetic simple.

• You have a $100 account.
• You open a $2,000 forex position, which is 20:1 leverage.
• You put a stop 1% away from entry. Your planned worst case is 1% of $2,000, or $20.
• Weekend news hits, and the market reopens 3% against you, well past your stop.
• The stop triggers at the first available price. Your loss is about 3% of $2,000, or $60, three times what you planned and 60% of the account.

Now run the same gap on a $3,000 position (30:1). A 3% move is a $90 loss, almost the whole account, from a single weekend. As one explainer of the EU rules puts it, at 30:1, a 3.3% move against your position can wipe out the margin you committed.

Leverage doesn't make gaps bigger. It makes each percentage point of gap cost more, relative to your account.

What regulators require, and what they can't prevent

In the EU, ESMA's rules on contracts for difference (CFDs) include leverage limits on opening positions; a margin close out rule on a per account basis; a negative balance protection on a per account basis. The retail leverage caps are 30:1 on major currency pairs, 20:1 on non-major pairs, major indices and gold, 10:1 on other commodities and non-major indices, 5:1 on individual equities, and 2:1 on cryptocurrencies. In the UK, the FCA retained the substance of the same measures.

The margin close-out rule doesn't beat a gap either. It closes positions once account equity falls to 50% of the minimum required margin. Closure happens at the next available price, which in a weekend gap or a news gap can sit far below the close-out level. That is why negative balance protection exists. It is designed as a backstop in case margin closeout doesn't trigger, or triggers late due to a sudden price movement.

These protections depend on where your broker is regulated and how you're classified. Protection is granted per account rather than per position, and it is a retail entitlement: a client reclassified as elective professional gives it up. Offshore brokers may offer none of it. Even with full protection, losing your whole deposit is still possible.

Practical ways traders think about weekend gap risk

None of these removes risk. They're common ways traders decide how much weekend exposure they can live with:

• Size for the gap, not just the stop. Ask what a much larger adverse move than your stop distance would cost, and whether your account could survive it.
• Use less leverage over weekends. Lower leverage means a given gap takes a smaller share of the account.
• Know your instrument's hours. Forex, index CFDs, crypto spot, crypto futures and crypto ETFs all follow different schedules.
• Check the calendar. Scheduled weekend events, such as elections or policy meetings, are known gap risks.
• Read your broker's terms. Find out how stops are triggered, whether guaranteed stops are offered and at what cost, how margin close-out works, and whether negative balance protection applies to your account.
• Don't count on gaps "filling." Some traders watch for price to return to Friday's close, but nothing guarantees it.

On Markitel's signals: they are the output of Markitel's rule-based ten-factor technical engine, which works from price data. A signal can't see weekend news before it happens and doesn't protect a position from gaps. Markitel is not a broker, custodian or adviser, and your orders run on your broker's systems and rules.

Key takeaways

• Gaps come from closed or thin markets. Forex and indices pause over the weekend, so news gets priced in all at once when trading resumes. Thin liquidity at the reopening can make the jump bigger.
• Crypto trades 24/7 but still has gap-like risk. It often takes the first hit from late-Friday shocks, its order books can thin out sharply under stress, and crypto products tied to stock-market hours can still gap.
• A stop-loss is a trigger, not a guaranteed price. Standard stops fill at the next available price, which can be far past your level. Stop-limits cap the price but may not fill at all.
• Leverage magnifies gap losses. On a small account, one gap can cost several times your planned loss, or the whole balance. Margin close-out can't stop that, and negative balance protection only applies where your broker's regulator requires it.
