What Happens When Futures Hit Limit Down? ES and NQ Price Limits

When ES or NQ futures hit limit down, the market does not close: it stays open, but no trade can print below the price limit (the largest move CME allows from the prior day's reference price), which is 7% in overnight hours. During US hours the limits become downside steps of 7%, 13% and 20% tied to stock market halts, and several prop firms bar trading, or opening new positions, within 2% of a price limit, so at those firms the line on equity index futures is a 5% move.

Key takeaway

CME equity index futures stay open at limit down but cannot trade beyond it: 7% up or down overnight, with a two-minute pause after a 3.5% move within an hour, per CME's entry in the FIA's 2023 paper. In US hours 7% and 13% drops halt futures with stocks, E-mini futures reopening after 10 minutes, and 20% ends the day. As of October 2026, prop firms such as Topstep and FTMO draw their line at a 5% move.

What does limit down mean for ES and NQ futures?

Limit down means price has reached the lowest level CME allows for that session: sellers can still trade at the limit, but nobody can trade below it. In the FIA paper on exchange volatility controls, CME's entry says: "If the market prices reach that 7% limit, up or down, the market remains open but trades cannot take place outside of the price limit."

A market sitting at the limit with sellers queued and no buyers is called locked limit down, and it is still open: any buyer at the limit price gets filled. CME's Globex limits and banding documentation states the general rule that orders trade at or within the daily limits, never outside them. The belief that limit down closes the market is wrong; what it can do is leave your exit waiting for a buyer.

What are the CME price limits for ES and NQ?

Overnight, from 5:00 pm to 8:30 am CT, equity index futures trade inside a 7% band up and down, with a 3.5% dynamic circuit breaker that pauses trading for two minutes. From 8:30 am CT the limits become downside steps of 7%, 13% and 20%, coordinated with the stock market's circuit breakers, and a 20% fall in the S&P 500 halts futures until the next day's stock open.

On top of the static overnight band sits the dynamic circuit breaker (DCB, a moving limit that pauses trading after a fast move). The FIA paper describes it this way: "During overnight hours, if the market moves beyond 3.5%, up or down, within an hour, trading is paused for two minutes." CME's dynamic circuit breaker documentation measures it over a rolling 60-minute look-back window and moves the market into a pre-open state when it triggers.

The same paper's CME entry covers the day session: "During daytime trading hours, CME Group U.S. equity futures circuit breakers are coordinated with cash equity market circuit breakers at 7%, 13%, and 20%." In CME's rule text as filed with the CFTC in March 2016, all three are written as the reference price minus an offset, so there is no daytime upside limit. From 2:25 pm to 3:00 pm CT only 20% applies, since a 7% or 13% stock drop at or after 3:25 pm ET no longer halts trading.

The overnight band has been 7% only since 12 October 2020, when CME widened it from 5% and added the 3.5% dynamic limits, according to the SROs' working group report on the March 2020 halts. A guide quoting a 5% overnight limit describes the old market. After the 3:00 pm CT stock close and until 4:00 pm, the 2016 text set a 5% limit up and down from that day's reference price, never below the 20% limit; AMP Futures' June 2021 price limit guide gives 7% for that hour, still not allowed past the day's 20% limit. Check CME's daily price limits page for the current figure.

Picture one day as a timeline in Chicago time. From 5:00 pm to 8:30 am a 7% band wraps price on both sides. At 8:30 am the band becomes three downside steps (7%, 13%, 20%), and at 2:25 pm the first two fall away until the 3:00 pm stock close.

Overnight the limit is a symmetrical box; at 8:30 am CT it becomes a staircase that only points down and moves with the stock market.

How long do futures halts last, and when does trading resume?

An overnight DCB pause lasts two minutes. In US hours, a 7% or 13% drop in the S&P 500 before 3:25 pm ET halts stocks for 15 minutes and E-mini futures reopen after 10; a 20% drop halts futures until the next day's stock open.

The SEC's investor bulletin gives the 15-minute stock halt, and the FIA's 2023 paper says the markets "are paused for 15 minutes". But the SROs' 2021 report states that since October 2020, E-mini S&P 500, Nasdaq-100, Dow and Russell 2000 futures resume after 10 minutes, five minutes before stocks.

Take the first halt of March 2020. The Level 1 breaker fired at 9:34:13 a.m. ET on March 9, according to the working group report; add 15 minutes and you get 9:49:13, the reopening-auction time the report records. Under today's rule, E-mini futures would reopen at 9:44:13 ET.

Halts are not instant either. The report says "CME halted affected symbols approximately one minute after each breach was triggered." About 4,400 futures and options contracts traded in those gaps across the four events, and none were nullified.

Why NQ can halt when ES does not

NQ has its own daytime 7% step. In the 2016 rule text, when NQ is limit offered at 7%, CME starts a 2-minute observation interval, and "If the Primary Futures Contract Month remains limit offered at its 7% Price Limit, futures trading shall halt for two (2) minutes," before resuming with the 13% limit. ES's 7% step waits for the stock market halt, so NQ can pause on a tech-led drop while the S&P 500 is still above its trigger.

How does CME calculate the limit price?

CME takes a reference price, the volume-weighted average price of the futures between 2:59:30 and 3:00:00 pm CT rounded down to the nearest 0.50 point, and subtracts an offset equal to the limit percentage of the cash index close, also rounded down to 0.50. That is the method in CME's 2016 filing; the current rulebook page could not be fetched, so treat it as dated.

The 30-second window works like the settlement window rather than the last trade. The offset applies to the cash index, not the futures, so the limit is not exactly 7% below the futures price. The difference is the basis between ES and the cash index. The table shows the ladder for ES at an illustrative reference of 6,000.00, with the cash close set equal to it.

Level	Points	ES price	What happens there
+7%	+420.00	6,420.00	Overnight ceiling; no daytime upside limit
-5%	-300.00	5,700.00	Firms' 2% zone begins
-7%	-420.00	5,580.00	Overnight floor; first daytime halt
-13%	-780.00	5,220.00	Second daytime halt
-20%	-1,200.00	4,800.00	Lowest limit of the day; a 20% S&P 500 fall halts trading to the next stock open

Computed by Phoenix Technologies; method: offset = percentage x cash close, rounded down to 0.50; limit = reference price minus offset (plus, for the overnight ceiling). Inputs are illustrative. The firm line sits 120 points above the overnight floor, and those 120 points are the room the 2% rule takes away.

Your working floor at a 2% rule firm is the 5% rung, 120 points above the price where the market actually locks.

Now add basis, with illustrative inputs. Step 1: a raw VWAP of 6,034.37 rounds down to a reference of 6,034.00. Step 2: 7% of a 6,010.12 cash close is 420.7084, rounded down to 420.50. Step 3: the limit is 6,034.00 minus 420.50, or 5,613.50. A firm's shortcut, a settlement of 6,035.25 times 0.93, gives 5,612.7825: 0.7175 points away. Close enough to decide when to stop, but read the limits CME publishes each day rather than computing them.

Can you sell or get stopped out when futures are limit down?

You can sell at the limit price only if a buyer takes the other side, and never below it. A sell stop that triggers on the way down becomes an order waiting at or above the limit, in a queue, until buyers arrive or the limit moves, so a stop does not guarantee an exit.

Picture the order book at an illustrative overnight floor of 5,580.00. Offers stack up at 5,580.00 and nothing trades below it. A sell stop at 5,600.00 triggered on the way down, and its unfilled remainder now rests as an offer at or above the limit, behind every earlier offer.

A triggered stop is not a fill: at a locked limit it becomes one more offer waiting behind earlier sellers for a buyer who may not come.

Where the remainder rests depends on the order type and CME's stop protection, explained in why stops fill away from their price. When trading resumes after a halt, fills can land far from the stop: slippage at its worst. How each retail platform treats a stop priced beyond the limit (rejected, held or accepted) varies, and no single public source covers them.

A trade copier, Thor included, replicates orders across accounts; it cannot fill an exit at a price the exchange will not trade, so every copied exit joins the same queue.

What does a limit-down move cost per ES, NQ, MES and MNQ contract?

At illustrative reference prices of 6,000 for ES and MES and 30,000 for NQ and MNQ, a full 7% limit move costs $21,000 per ES, $42,000 per NQ, $2,100 per MES and $4,200 per MNQ. Against an illustrative $2,000 loss buffer, even one MES held to the limit overshoots by $100.

The multipliers are $50 per point for ES and $20 for NQ in CME's 2016 rule text, and $5 for MES and $2 for MNQ in CME's June 2026 micro options filing.

Contract	$ per point	3.5% DCB move	5% firm line	7% limit	$2,000 buffer covers
ES	$50	210 pts, $10,500	300 pts, $15,000	420 pts, $21,000	40 pts (0.667%)
MES	$5	210 pts, $1,050	300 pts, $1,500	420 pts, $2,100	400 pts (6.667%)
NQ	$20	1,050 pts, $21,000	1,500 pts, $30,000	2,100 pts, $42,000	100 pts (0.333%)
MNQ	$2	1,050 pts, $2,100	1,500 pts, $3,000	2,100 pts, $4,200	1,000 pts (3.333%)

Computed by Phoenix Technologies; method: points = percentage x reference, rounded down to 0.50 (0.25 for the DCB); dollars = points x multiplier; buffer points = $2,000 / multiplier. On full-size contracts the buffer is gone at under 1%, long before any limit; the limit matters for what it does to your exit.

Walk one MES through it. Step 1: 7% of 6,000 is 420 points. Step 2: 420 x $5 is $2,100, which is $100 past a $2,000 buffer. Step 3: at the firm's 5% line, 300 x $5 is $1,500, inside it. One ES held to the limit loses 10.5 times the buffer.

That gap is the case for sizing against the drawdown limit and for knowing which contract size fits your account.

On full-size contracts the buffer is gone long before any limit; only a single micro gets close, and at the limit even one MES crosses it.

What is the prop firm 2% price limit rule?

Several futures prop firms prohibit trading once price is within 2% of a CME price limit, which on 7% equity index limits means stopping at a 5% move. As of October 2026, Topstep, MyFundedFutures, Alpha Futures, FundedNext Futures and FTMO all publish a version, but they word, measure and enforce it differently.

Topstep's help page gives the reason: "When a product is within 2% of a price limit, market conditions are extreme and execution is unreliable." Alpha Futures is explicit about scope: "This prohibited conduct is enforced on ALL Alpha Futures Accounts, not just Evaluations."

Firm	How the page words it	Measured from	Accounts covered	Stated consequence
Topstep	Stop as % net change approaches limit minus 2%	Settlement x (1 - limit% + 2%)	Not stated	Not stated
MyFundedFutures	Trading within 2% of a CME limit is prohibited	Settlement; limits updated 5:05 PM EST	Sim Funded and Live Funded	Not stated
Alpha Futures	Prohibited conduct within 2% of a limit	% net change	All accounts	Not stated
FundedNext Futures	Trading within 2% of the limit is prohibited	Reference price x 0.95 or x 1.05	Not stated	Profit deductions, trading restrictions or suspension
FTMO	No new positions past 5%	Previous settlement	New positions	May terminate the account

Firm pages as of October 2026; check the firm's current rules before buying. Only two of the five name a penalty. FTMO writes: "If the rule is violated, FTMO has the right to terminate the trading account." FundedNext lists profit deductions, trading restrictions or account suspension, and a suspended account with open positions is its own problem.

The line is 5% at every firm, but the base, the accounts covered and the penalty differ, so read your own firm's page.

Two points the firm pages skip. Topstep's main ES worked example still uses a 5% limit, though overnight equity limits went to 7% in October 2020. And none of the firms use CME's exact base; the worked example above puts the gap under 1 point, so obey your firm's own line. Funded Futures Family's rule page returned an error when checked on 2026-10-16, so it is left out.

Has ES actually hit limit down?

Yes. US stocks had four market-wide halts in March 2020, on March 9, 12, 16 and 18, and the working group's report notes that "the E-mini S&P 500 futures had entered a limit-down state before the March 9, 12, and 16 Level 1 MWCB halts". Those overnight locks came at the old 5% limit.

March 9, 2020 was a Monday, so the first lock came in the Sunday evening session (see the CME Sunday reopen). The FIA's 2023 paper counts three occasions; the working group, which studied each event, lists four dates. The same report says S&P 500 losses as large as 7%, prior close to next day's low, happened 16 times since 1962.

No CME count of 7% overnight locks since October 2020 turned up, and no public data shows how many traders or prop accounts were caught at a limit. The fear that limits act as a magnet, pulling price toward them, is unsupported: the working group found no evidence of a magnet effect at the 7% and 13% triggers and drew no conclusion for 20%.

What should you check before a high-risk session?

Before any session with event risk, write down three prices: the day's 7% limit, your firm's 5% line, and the point where your loss buffer runs out. Whichever comes first is your real exit, and on full-size contracts that is almost always the buffer.

Read the day's published limits after the reset. FundedNext's page says the limits update at 4:05 PM CT after each session, the same moment as MyFundedFutures' 5:05 PM EST.
Mark your firm's line at 5% from the base it names (settlement, reference price or net change).
Convert both into dollars per contract: 300 ES points to the line is $15,000; on one MES it is $1,500.
Check which scheduled releases move ES and NQ and whether you hold across the 5:00 pm CT reopen.
On NQ in US hours, allow for its own 7% halt, which can come before any S&P 500 market-wide halt.
If you hold overnight, a stop cannot exit below the limit; a long put can, at a premium (see hedging futures with options), and your firm's overnight hold rules come first.

The decision rule: if your buffer is smaller than one 3.5% overnight move on your size (210 ES points, $1,050 per MES), trade smaller or go flat before the overnight session. If your firm has a 2% rule, flatten at the 5% line even when you expect a bounce. You will sometimes miss the rebound; that is the price of an exit the exchange can still give you.

Frequently asked questions

Do micro futures like MES and MNQ have the same price limits as ES and NQ?

Yes. The October 2020 change to 7% overnight limits and 3.5% dynamic limits covered the E-mini and Micro E-mini S&P 500 and Nasdaq contracts alike, according to the SROs' 2021 report. A micro moves the same number of points to the limit; only the dollars per point differ, $5 for MES against $50 for ES.

Do Dow and Russell 2000 futures follow the same limit rules?

Largely. The SROs' report lists E-mini Dow and E-mini Russell 2000 among the contracts that moved to 7% overnight limits with 3.5% dynamic limits in October 2020, and lists Dow and Russell 2000 futures among the products that reopen 10 minutes after a Level 1 or Level 2 stock halt. CME's 2016 rule text used the same observation-and-halt design for E-mini Russell 1000 as for the Nasdaq-100, but it did not cover Dow or Russell 2000 futures, so check their current contract rules for the daytime steps.

Is limit down the same thing as a trading halt?

No. At a price limit the market stays open and trades at or inside the limit, while a halt stops all trading for a set time. Overnight, ES can sit at its 7% limit for as long as sellers outnumber buyers without the limit itself halting trading; in US hours the 7% and 13% steps line up with halts.

What was the ES overnight limit before October 2020?

It was 5%. CME changed overnight hard limits on equity index futures from 5% to 7% effective 12 October 2020, according to the SROs' 2021 report. Topstep's main ES worked example on its help page still uses a 5% limit, so check which limit any example assumes before reusing its levels.

Why do prop firms stop you at 2% before the limit instead of at the limit?

Because execution near a limit cannot be relied on. Topstep says conditions within 2% of a limit are extreme and execution is unreliable, and Alpha Futures cites the risk of being trapped in a halt.

Can I keep an existing position open inside the 2% zone?

The firms word this differently, so check yours. FTMO frames its rule as a restriction on opening new positions once price has moved more than 5% from the previous settlement, while MyFundedFutures, Alpha Futures and FundedNext describe trading within 2% of the limit as prohibited.

If ES hits the 20% limit, does NQ keep trading?

No. The Level 3 halt is triggered by a 20% fall in the S&P 500 index, and under CME's 2016 rule text NQ is also halted by market-wide halts based on the S&P 500, so a Level 3 halt stops NQ along with ES until the next day's stock open.

Is there a limit up on ES during US trading hours?

No. CME's 2016 rule text writes the 7%, 13% and 20% daytime steps as the reference price minus an offset, so there is no upside limit from 8:30 am to 3:00 pm CT. The 7% upside limit applies overnight, from 5:00 pm to 8:30 am CT. From 3:00 to 4:00 pm CT, after the stock close, the 2016 text set a 5% limit up and down; AMP Futures' June 2021 guide gives 7% for that hour.
