To trade E-mini futures, you open an account with a registered futures broker, post margin, and buy or sell the E-mini S&P 500 (ES) or the Micro E-mini S&P 500 (MES), which is one-tenth the size. One ES point is worth $50 and one 0.25-point tick $12.50; on MES the figures are $5 and $1.25. Both trade nearly 24 hours on CME Globex, expire on the third Friday of March, June, September and December, and settle in cash. Margins change, losses can exceed your deposit and no strategy is reliable, so size every trade from its stop and practice in simulation first.
Checked against CME Group's contract specifications, rulebook, roll calendar and data fee lists, and IRS Form 6781, on October 1, 2026. This rewrite removes fixed margin and account-size figures, a fixed-percentage risk rule, unsourced claims about the best hours to trade and an opening-range setup presented as reliable.
What Are E-mini Futures? ES and MES Explained
E-mini futures are electronically traded stock index futures listed by CME Group. “The E-mini” (also written emini or e mini) almost always means the E-mini S&P 500, ticker ES, which CME launched on September 9, 1997 at one-fifth the size of the original S&P 500 futures contract. The Micro E-mini S&P 500, ticker MES, followed in May 2019 at one-tenth the size of ES.
You don't own any stocks: you hold a contract whose value moves with the S&P 500 times a fixed dollar amount. Selling short is as simple as buying, and CME's ES page notes there is no uptick rule or special requirement for it.
ES Futures Contract Specs: ES vs MES
| Specification | E-mini S&P 500 (ES) | Micro E-mini S&P 500 (MES) |
|---|---|---|
| Contract size | $50 × S&P 500 Index | $5 × S&P 500 Index |
| Minimum tick | 0.25 index points = $12.50 | 0.25 index points = $1.25 |
| One point (4 ticks) | $50 | $5 |
| CME Globex hours | Sunday 6:00 p.m. to Friday 5:00 p.m. ET, daily break 5:00 to 6:00 p.m. ET | Same as ES |
| Contract months | March, June, September, December | Same as ES |
| Last trading time | 9:30 a.m. ET on the third Friday of the contract month | Same as ES |
| Settlement | Cash, to a special opening quotation of the S&P 500 | Same as ES |
| Customary roll date | Monday before the third Friday | Same as ES |

Notional value is the index level times the multiplier. At an example index level of 7,000, one ES controls $350,000 of exposure and one MES $35,000, so a 1% move of 70 points is $3,500 on ES and $350 on MES. A far smaller margin deposit controls all of it. The free ES futures calculator converts any move into ticks and dollars.
ES Futures Trading Hours, Expiration and the Roll
- Globex hours: Sunday 6:00 p.m. to Friday 5:00 p.m. ET, with a daily break from 5:00 to 6:00 p.m. ET. Some holidays shorten the session.
- Cash session: the NYSE core session runs from 9:30 a.m. to 4:00 p.m. ET, and many traders treat it separately from overnight trading.
- Scheduled releases: the BLS Employment Situation report comes out at 8:30 a.m. ET and FOMC statements at 2:00 p.m. ET. Prices can jump through stops around both.
- Price limits: CME applies 7% limits overnight and 7%, 13% and 20% limits tied to NYSE circuit breakers during the day (CME price limits). A halt can leave you unable to exit.
Expiration and rolling to the next contract
Each contract stops trading at 9:30 a.m. ET on the third Friday of its month and settles in cash. CME's customary roll date is the Monday before, after which the next quarter is customarily identified as the lead month because the expiring contract “will have a less liquid market.” You can roll at any time, by closing one month and opening the next or with a calendar spread, which ES quotes in 0.05-point steps worth $2.50.
| Contract | Month code | CME roll date | Last trading day |
|---|---|---|---|
| December 2026 | Z | Monday, December 14, 2026 | Friday, December 18, 2026 |
| March 2027 | H | Monday, March 15, 2027 | Friday, March 19, 2027 |
| June 2027 | M | Monday, June 14, 2027 | Friday, June 18, 2027 |
| September 2027 | U | Monday, September 13, 2027 | Friday, September 17, 2027 |

E-mini Margin: Why There Is No Fixed Number
Futures margin is a performance bond, a good-faith deposit rather than a loan. Initial margin opens a position; maintenance margin is the level your account must stay above. CME Clearing sets minimum levels that vary by product and with volatility, and publishes current ES figures on its margins page. Your broker must collect at least that, can require more, and may set its own levels for positions opened and closed in the same session, so read its policy.
Gains and losses are settled every trading day, and the CFTC's futures basics warn that many individuals “lose all of their money, and can be required to pay more than they invested initially.” If your account falls below maintenance, expect a margin call or forced liquidation.
So “how much money do I need?” has no fixed answer. Add the margin your broker requires to your maximum loss per trade and per day, and use only money you can afford to lose. If one MES contract with a logical stop exceeds your per-trade limit, there is no trade.
How an E-mini Trade Works, Step by Step
- Open and fund an account with a broker registered with the CFTC and the National Futures Association. Look it up in NFA's BASIC database first.
- Set up CME data and a platform. Costs are listed below.
- Pick the lead month: usually the nearest quarter until its roll date, then the next one.
- Write the plan: setup, entry, a stop at the price that shows the idea is wrong, an exit rule and a size calculated from the stop.
- Enter with a bracket order so the stop and target are attached to the entry.
- Manage it as written: no widening the stop and no adding to a loser.
- Settlement and exit: while the trade is open, the account is credited or debited at each daily settlement. Closing it realizes the rest.
- Keep records. Log fills, costs and slippage. Your broker's Form 1099-B reports regulated futures results in box 11 for Form 6781.
Worked example (hypothetical)
These prices are made up to show the arithmetic. They are not a forecast or a recommendation.
- Limit: a $100 maximum loss on this trade.
- Entry and stop: buy MES at 7,010.00 with a stop at 7,004.00. Six points (24 ticks) is $30 per MES contract, or $300 per ES contract.
- Size: $100 ÷ $30 = 3.33, rounded down to 3 MES with $90 at risk. One ES would risk $300, so ES doesn't fit this plan.
- Target: 7,022.00, 12 points away: $60 per MES, or $180 for three.
- Costs: assume fees and slippage of 1 tick ($1.25) per MES round trip, $3.75 in total. Your broker's costs may differ.
- Results: at the target, +$180 − $3.75 = +$176.25. At the stop, −$90 − $3.75 = −$93.75, or more if the stop fills beyond its price.
E-mini Futures Trading Strategies: Four Common Approaches
Most E-mini futures trading strategies are variations on four ideas. None has verified results, each fails in predictable conditions, and all need testing with costs included before they deserve real money.
| Approach | Core idea | Where it breaks down |
|---|---|---|
| Trend following | Trade in the direction of an established move, on breakouts or pullbacks | Choppy, range-bound sessions produce repeated false starts |
| Mean reversion | Fade stretched moves back toward an average or the middle of a range | On a trend day price keeps moving away from the average |
| Opening range | Trade a break, or a failed break, of the first minutes after the 9:30 a.m. ET open | Breakouts can fall back into the range, and a wide range forces a wide stop |
| VWAP and volume profile | Use volume-weighted average price, or prices where most volume traded, as reference levels | Levels change with your session and settings, and trend days ignore them |
Trend following
Rules define a trend with a moving average, higher highs and lows, or a range break, and enter in that direction with a stop beyond the last swing. In balanced sessions it can pay for many small failed entries.
Mean reversion
Rules fade a move stretched far from a reference such as VWAP or the prior session's value area. It can look dependable in quiet markets; on the day the move keeps going, the hard stop is what limits the loss.
Opening range
The range is the high and low of the first 5, 15 or 30 minutes after the cash open. Breakout traders enter on a close beyond it, fade traders on a failed break. Our ES futures trading strategy guide works through a 30-minute version with an invalidation rule.
VWAP and volume profile
VWAP is the running total of price times volume divided by the running total of volume since the session began, so a line starting at the 6:00 p.m. ET Globex open differs from one starting at the 9:30 a.m. cash open. Most platforms call the range holding about 70% of a session's volume the value area. Write your settings into the rules. The order flow guide explains these tools, and our ES scalping strategies guide has five short-term templates built on them.
Keep the base rates in mind. Of individuals who day traded Brazilian equity futures for more than 300 days, 97% lost money (Chague, De-Losso and Giovannetti), and less than 1% of Taiwanese stock day traders could predictably earn positive abnormal returns net of fees (Barber, Lee, Liu and Odean).
Position Sizing: The Math Before Every Trade
Size comes from the stop. Risk per contract is the stop distance in points times $50 for ES or $5 for MES. Divide your maximum loss for the trade by it and round down; zero means no trade. With a $150 limit, before costs:
| Stop distance | ES risk per contract | ES contracts | MES risk per contract | MES contracts |
|---|---|---|---|---|
| 3 points (12 ticks) | $150 | 1 | $15 | 10 |
| 6 points (24 ticks) | $300 | 0: no trade | $30 | 5 |
| 12 points (48 ticks) | $600 | 0: no trade | $60 | 2 |
Set a daily loss limit in dollars the same way, before the session starts. Stop-market orders can fill beyond their price in a fast market or after a gap, so a real loss can exceed the table.
What It Costs to Trade E-mini Futures
| Cost | Who sets it | What to know |
|---|---|---|
| Commission | Your broker | Per contract, per side; compare all-in rates |
| Exchange and clearing fees | CME, passed on by your broker | Per contract on every fill; if MES fees are more than one-tenth of ES fees, they take a larger share of each $1.25 tick |
| NFA assessment fee | National Futures Association | $0.01 per side per contract, returning to $0.02 on July 1, 2027 |
| Market data | CME, plus any vendor charge | Non-professionals pay CME $1.55 a month per exchange for top-of-book data or $12.10 for depth (June 1, 2026 list), rising to $1.60 and $12.50 on January 1, 2027 |
| Trading platform | The platform provider | Some come with a brokerage account; others charge monthly or for a license |
| Slippage | The market | $12.50 per ES tick and $1.25 per MES tick, and it can be larger around scheduled releases |

How E-mini Futures Are Taxed in the US
- Section 1256 treatment: gains and losses on regulated futures count as 60% long-term and 40% short-term, regardless of how long you held them.
- Year-end mark to market: a contract still open at year end is treated as sold at fair market value on the last business day of the year, and the wash sale rules don't apply.
- Reporting: the aggregate profit or loss in box 11 of your broker's Form 1099-B goes on line 1 of Form 6781.
- Loss carryback: individuals with a net section 1256 contracts loss can elect to carry it back three years, but only against section 1256 gains in those years.

Risk Checklist Before Your First Live Trade
- You can state the tick value, the hours, the month you trade and when it expires.
- You have checked your broker in NFA BASIC and read its margin and liquidation policy.
- Your rules for context, entry, stop, size and exit are written down and tested in simulation, with commissions, fees and at least one tick of slippage per side included.
- Your maximum losses per trade and per day are set in dollars, and you stop at the daily one.
- You know the day's scheduled releases and whether your rules trade through them.
- Every position has an attached stop, and you know whether it is held at the exchange or only on your computer.
- The account holds only money you can afford to lose.
Simulated results have limits: CFTC rules require advisors who show them to warn that they don't represent actual trading and benefit from hindsight (17 CFR 4.41). Our futures trading psychology guide covers the habits that break first under pressure.
Futures Risk Warning
Futures use leverage, so losses can build quickly and exceed the amount you deposit. Use only money you can afford to lose, confirm margin and liquidation policies with your broker, and remember that simulation cannot reproduce every live fill, gap or emotional reaction.

E-mini Futures FAQ
What is the difference between ES and MES futures?
Both track the S&P 500 on CME Globex with the same 0.25-point tick, hours and expirations. ES is $50 times the index ($12.50 per tick); MES is $5 times the index ($1.25 per tick), one-tenth the size, so you can size a position in smaller steps.
How much is one point worth on ES and MES?
One ES point is worth $50 and one MES point $5, per CME Group's contract specifications. A point is four 0.25-point ticks, so a 10-point move is $500 per ES contract and $50 per MES contract, before costs.
How much money do I need to trade E-mini futures?
There is no fixed amount. CME Clearing sets minimum margins that change with volatility, brokers can require more, and losses can exceed your deposit. Start from your broker's margin plus your maximum loss per trade and per day, and use only money you can afford to lose.
When do ES futures expire and roll?
Trading ends at 9:30 a.m. ET on the third Friday of March, June, September and December, and the contract settles in cash. CME's customary roll date is the Monday before: December 14, 2026 for the December 2026 contract, which expires on December 18.
What are the trading hours for ES futures?
On CME Globex, ES and MES trade from Sunday 6:00 p.m. to Friday 5:00 p.m. ET, with a daily break from 5:00 to 6:00 p.m. ET. The stock market's regular session runs from 9:30 a.m. to 4:00 p.m. ET, and some holidays shorten trading hours.
How are E-mini futures taxed in the US?
The IRS treats them as section 1256 contracts: gains and losses count as 60% long-term and 40% short-term regardless of holding period, open positions are marked to market at year end, and you report them on Form 6781. Rules differ outside the US, so ask a tax professional.
