How long a trading halt lasts depends entirely on what triggered it. A single-stock volatility pause runs five minutes and can extend in five-minute increments until the stock can reopen. A market-wide circuit breaker at the first or second level halts trading for 15 minutes; at the third level, trading stops for the rest of the day. A news pending halt has no fixed clock and usually clears within 30 to 60 minutes. And an SEC trading suspension can freeze a stock for up to 10 business days.
Five-Minute Volatility Pauses on a Single Stock
Individual stocks are protected by the Limit Up-Limit Down (LULD) plan, which sets price bands above and below a reference price updated every five minutes.1FINRA. Limit Up/Limit Down (LULD) Plan When quotes hit a band, the stock enters a “limit state.” If that state doesn’t resolve within 15 consecutive seconds, the exchange declares a five-minute pause.2SEC. Limit Up-Limit Down Pilot Plan and Extraordinary Transitory Volatility
At the end of those five minutes, the exchange runs a reopening auction. If the auction can’t produce a price inside the bands, the halt extends for another five minutes, and the exchange widens the auction price collars.3NYSE. U.S. Equity Market Resiliency During Times of Extreme Volatility Those five-minute extensions repeat until the stock can reopen. So the floor is five minutes; the ceiling is however long it takes to find a stable price.
The band widths themselves vary by stock tier and price, and they double during the last 25 minutes of the trading day to accommodate closing volatility.4LULD Plan. Limit Up Limit Down The bands change how easily a pause is triggered, not how long it lasts once it starts.
Market-Wide Circuit Breakers: 15 Minutes or the Rest of the Day
When the entire S&P 500 drops sharply from the previous day’s close, circuit breakers halt every U.S. equity and options exchange at once under NYSE Rule 7.12 and equivalent rules.5NYSE. Market-Wide Circuit Breakers FAQ There are three levels, each measured from the prior close:
- Level 1 — 7% decline. Triggered between 9:30 a.m. and 3:25 p.m. ET, trading pauses for 15 minutes. Triggered at or after 3:25 p.m. ET, trading continues without a halt.
- Level 2 — 13% decline. Same rule: 15 minutes if before 3:25 p.m. ET, no halt at or after.
- Level 3 — 20% decline. Trading halts for the remainder of the day regardless of when it hits. Trading resumes at the open of the next business day.
The 3:25 p.m. cutoff exists so that a late halt doesn’t disrupt the closing auction.6Securities and Exchange Commission. Self-Regulatory Organizations – New York Stock Exchange LLC – Notice of Filing To Extend the Pilot Related to the Market-Wide Circuit Breaker in Rule 7.12 Each level can only trigger once per day. If the market falls 7%, halts, rebounds, and later crosses 7% again, no second Level 1 halt fires; the market would have to reach Level 2 or Level 3 for another stop.7Cboe.

News Pending Halts: No Fixed Clock
When a company is about to release material information such as an earnings revision, a merger announcement, or a regulatory action, the exchange halts trading so all investors get the news at the same time. On Nasdaq, this pause carries halt code T1 (news pending) or T2 (news released, dissemination in progress).8Nasdaq Trader. Trading Halts Code Data Fields and Definitions
No rule fixes the duration. The halt ends when the exchange determines the news has been fully distributed through compliant channels. Most last roughly 30 to 60 minutes. Complex disclosures can stretch the pause across several hours or the whole session. Once the exchange lifts the halt, it opens a short quotation period so market makers can post updated bids and offers before continuous trading resumes.
During regular hours, the exchange can call a news halt on its own. In the pre-market session (4:00 a.m. to 9:30 a.m. ET), Nasdaq halts for news dissemination only at the issuer’s request.9The Nasdaq Stock Market. Nasdaq Equity 4 – Equity Trading Rules
SEC Trading Suspensions: Up to 10 Business Days
The SEC’s authority is much broader than the exchanges’. Under Section 12(k) of the Securities Exchange Act of 1934, the SEC can suspend trading in any individual security for up to 10 business days when it believes the public interest and investor protection require it.10Office of the Law Revision Counsel. 15 USC 78l – Registration Requirements for Securities These suspensions typically follow concerns about fraud, missing or inaccurate financial filings, or questionable public information about the company.
During those 10 business days, you cannot buy or sell the security on any U.S. exchange or in the over-the-counter market.11SEC. Investor Bulletin – Trading Suspensions The same statute gives the SEC even broader emergency authority: it can suspend all trading across every national exchange for up to 90 calendar days, subject to Presidential notification, and it can issue emergency orders imposing restrictions for up to 10 business days, extendable to a maximum of 30 calendar days if the emergency persists.10Office of the Law Revision Counsel. 15 USC 78l – Registration Requirements for Securities
What Happens to Your Open Orders During a Halt
While a halt is in effect, your broker cannot execute trades in the halted security or publish quotations for it, and every other U.S. venue trading the same stock must observe the halt too.12FINRA. Trading Halts, Delays and Suspensions What happens to your existing orders depends on the order type and the broker’s protocols. Some routing systems hold orders through the halt so they can participate in the reopening auction; others cancel orders that were pending when the halt began.
Market orders carry the most risk into a reopening. Halts often follow a sharp price move or a major news event, and the reopening price can gap far from where the stock last traded. A market order will fill at whatever the reopening auction produces, which could be well above or below the price you saw. Limit orders give you more control but may not fill at all if the reopening price falls outside your limit. If you hold open orders on a stock that gets halted, ask your broker whether those orders will carry into the reopening or need to be re-entered.
When the Suspension Ends but Normal Trading Doesn’t Return
The end of a 10-day SEC suspension doesn’t mean the stock returns to its exchange. The company often loses its listing and can only trade over the counter afterward, and even that isn’t automatic. Before a broker-dealer can publish quotations again, federal rules require it to review specified company documents, including recent financials, and to have a reasonable basis to believe that information is accurate.13eCFR. 17 CFR 240.15c2-11 – Publication or Submission of Quotations Without Specified Information
When trading does resume, prices are often dramatically lower because the suspension itself raises doubts about the company. If no buyer emerges at all, the SEC cautions that the shares may be worthless and suggests consulting a tax advisor about how to treat the loss.11SEC. Investor Bulletin – Trading Suspensions So while the legal maximum for an SEC suspension is 10 business days, the practical outage for shareholders can be much longer.
