CME Group lists E-nano equity index futures on August 24, pending regulatory review, covering the S&P 500, Nasdaq-100, Russell 2000 and Dow Jones Industrial Average at one tenth the size of a Micro E-mini. NinjaTrader and Robinhood are the only two platforms CME named at announcement.
Almost every write-up leads with that size. It is accurate and it is the least useful number in the specification. The tick is not one tenth. CME set the E-nano tick at double the index-point increment of its Micro and E-mini counterparts, so the dollar value of a tick falls by five while the contract falls by ten. Your position gets ten times smaller and your price resolution gets twice as coarse at the same moment.
This covers the verified specifications, what that gap does to your cost per trade, and what to check on NinjaTrader before the first session. Every contract figure comes from CME’s own published FAQ.
E-nano futures contract specs
| Product | Code | Multiplier | Tick size | Value per tick |
|---|---|---|---|---|
| E-nano S&P 500 | NES | $0.50 | 0.50 index points | $0.25 |
| E-nano Nasdaq-100 | NNQ | $0.20 | 0.50 index points | $0.10 |
| E-nano Russell 2000 | N2K | $0.50 | 0.20 index points | $0.10 |
| E-nano Dow Jones | NDOW | $0.05 | 2.00 index points | $0.10 |
NES, NNQ and N2K list under CME. NDOW lists under CBOT, which matches how the Micro and E-mini versions are already split.
The rest of the mechanics, from the same source. Financially settled against the Special Opening Quotation on the contract month’s third Friday, the same print that settles the E-mini and the Micro. Only the nearest two quarterly months list at any time, from the March, June, September and December cycle. Trading runs Sunday 6:00 p.m. through Friday 5:00 p.m. Eastern, with the daily maintenance break from 5:00 to 6:00 p.m. Daily settlement comes from a 30-second volume-weighted average of Globex trades in the corresponding E-mini between 3:59:30 and 4:00:00 p.m. Eastern, rounded to the nearest E-nano tick. Price limits and circuit breakers follow the same rules as the larger contracts.
Two exclusions to know before building around them: E-nano contracts are not eligible for block trading or BTIC, and E-nano volume does not count toward CME’s volume-based fee discounts.
E-nano vs Micro E-mini vs E-mini
The three sizes side by side, using CME’s figures:
| E-nano | Micro E-mini | E-mini | |
|---|---|---|---|
| S&P 500 multiplier | $0.50 | $5 | $50 |
| Nasdaq-100 multiplier | $0.20 | $2 | $20 |
| Russell 2000 multiplier | $0.50 | $5 | $50 |
| Dow multiplier | $0.05 | $0.50 | $5 |
| S&P 500 tick size | 0.50 pts | 0.25 pts | 0.25 pts |
| S&P 500 tick value | $0.25 | $1.25 | $12.50 |
| Underlying index | Same | Same | Same |
| Settlement | SOQ, third Friday | SOQ, third Friday | SOQ, third Friday |
| Session | 23 hours | 23 hours | 23 hours |
Notional exposure follows the multiplier. At a hypothetical S&P 500 level of 7,000, one E-nano carries about $3,500 of exposure against roughly $35,000 for a Micro and $350,000 for an E-mini. Those figures move with the index and are illustrative only.
One detail worth having if you run mixed sizes: CME allows E-nano positions to be offset against opposing positions in their counterparts, at 10:1 against Micro E-minis and 100:1 against E-minis. Offsets go through your clearing broker to the clearinghouse rather than happening automatically.
The E-nano tick value math most coverage skips
The multiplier drops by ten. The tick doubles. Together those two published facts mean the dollar value of one tick drops by five, not ten, and it holds identically across all four contracts.
| Index | E-nano tick value | Micro E-mini tick value | Ratio |
|---|---|---|---|
| S&P 500 | $0.25 | $1.25 | 5x smaller |
| Nasdaq-100 | $0.10 | $0.50 | 5x smaller |
| Russell 2000 | $0.10 | $0.50 | 5x smaller |
| Dow Jones | $0.10 | $0.50 | 5x smaller |
The missing factor of two turns up as price resolution. An E-nano moves in index-point steps twice as wide as a Micro. On the S&P 500 you quote and stop in half-point increments rather than quarter-point. On the Dow it is two-point steps rather than one.
That is a real trade-off and it runs against how the product is being sold. A smaller contract buys finer control over exposure. It costs coarser control over price. If your method depends on precise stop placement more than on precise position sizing, E-nano hands you the thing you did not need and takes away the thing you did.
It is also being described loosely elsewhere. At least one broker guide currently ranking says the tick value “still lands close to what a Micro trader is used to.” Measured against a pure one-tenth scaling that is fair, since $0.25 is more than $0.125. Read plainly it is misleading: twenty-five cents against a dollar twenty-five is one fifth, not close. Work from CME’s table.
What E-nano futures actually cost to trade
Exchange fees aside, the number that decides whether these are tradeable is your broker’s per-contract commission, and it has not been published by anyone.
Here is why it matters more than usual. If a broker charges the same flat per-contract rate on an E-nano as on a Micro, you need five times as many ticks to cover it. Not ten times smaller cost against ten times smaller contract, which would be neutral. Five. Commission drag per unit of exposure roughly doubles unless the per-contract rate comes down with the contract size.
So the question to put to your broker before August 24 is not whether they will list E-nano. It is whether they will price it as a separate tier. A nano-tier commission makes these contracts a legitimate tool for small accounts. Micro-tier pricing on a nano-sized contract turns them into an expensive way to trade the same index.
Margins are the other unpublished number. CME’s FAQ points to its margins page rather than quoting a figure, so treat anything specific you see before launch as somebody’s estimate.
E-nano futures on NinjaTrader: what to check
NinjaTrader’s CEO is quoted in CME’s announcement and the platform is one of two CME named, so its users are well placed for day-one access. That said, a contract being listed by the exchange and being enabled, symbol-mapped and priced on a platform are separate steps. Four things worth confirming rather than assuming.
The instruments exist and are subscribed. NES, NNQ, N2K and NDOW are new instruments. Confirm they appear, and confirm your market data subscription covers them. CME and CBOT are separate designated contract markets, and NDOW sits on CBOT while the other three sit on CME.
Only two contract months list. The nearest two quarterly months exist and nothing further out. If you use continuous contracts or automatic rolls, that is a shorter ladder than the Micro and E-mini series you are used to.
Commission tier. Covered above and worth repeating because it is the number that decides everything else.
Your simulator uses real specs. Practising on the wrong tick value teaches the wrong position size. Check that the simulated instrument carries a $0.25 tick on NES rather than inheriting a Micro’s $1.25.
What changes for automated traders
If you trade discretionarily, a listing is a small event. If you run automation, a new contract size touches more of the stack than people expect, and one of these failure modes is silent.
Hard-coded tick values are the dangerous one. If your sizing or risk module has $1.25 or $0.50 per tick written into it anywhere, pointing it at an E-nano produces a position five times larger than intended in tick terms. It does not error. It just runs, and it runs in the direction of more risk.
Tick-denominated stops change meaning. A ten-tick stop on MES is 2.5 index points. A ten-tick stop on NES is 5.0 index points. Same number, double the market distance. Convert stops and targets to index points and re-derive them rather than copying across.
Settlement comes from somewhere else. E-nano daily settlement is derived from the E-mini’s VWAP, not from E-nano trades. If any reconciliation step assumes an instrument settles off its own tape, that assumption does not hold here.
Backtests will flatter you. There is no E-nano price history. A backtest on Micro data with the multiplier scaled down models the fills you would have got in a deep book, not the ones you will get in a new one. Day-one spreads and depth on any new listing are their own thing.
E-nano futures for prop firm traders
This is the group with the most to gain and the least published information.
The mechanical appeal is clear. Evaluation accounts live inside fixed daily loss limits and trailing drawdowns, and contract granularity decides how you scale inside them. A contract one tenth the size of a Micro gives you ten times the steps within the same drawdown budget, which matters when the difference between passing and failing is one oversized trade.
What nobody knows yet is how firms will count them. Every firm publishes a contract-equivalency table setting how each size counts toward position limits, and none appear to have stated where E-nano lands. Whether it counts as a tenth of a Micro, gets its own category, or is excluded during evaluations is unpublished. Firms also face the commission arithmetic above from the other side, since flat per-contract clearing costs on tiny contracts come out of their margin rather than yours.
Ask your firm directly before the launch date rather than assuming a favourable ratio. The firms that answer early are telling you something useful about how carefully they think.
What is still unknown
Short list, and worth more than the confident parts.
Margins. Unpublished by CME.
Commissions. Unpublished by any broker, including the two launch partners.
Prop firm treatment. Unpublished.
Liquidity. Unknowable before the contracts trade. Nobody can tell you what the spread will be.
The launch itself is described by CME as pending regulatory review, and that qualifier is still in place.
Does E-nano change your infrastructure needs?
Our honest read, as a company that hosts NinjaTrader and other futures platforms for automated traders.
Mostly no, and we would rather say so. E-nano exists because index levels priced retail out of Micros. That is a position-sizing problem rather than an execution-speed one, and a smaller contract does not make a fill arrive sooner. If you trade one or two E-nanos by hand from a laptop, nothing about this launch means you need hosting.
What does not change is the case that already existed: automated strategies that must run while you are away, that cannot survive a dropped connection mid-position, and that suffer when a home connection adds variability to order submission. A new listing adds one specific version of that. Launch-day books are thin and unpredictable, which is exactly when an interrupted session costs most.
The useful preparation for August 24 is not faster hardware. It is correct symbol mappings, correct tick values, converted stops, and something that stays up through the session. If you want a baseline on your current path first, our latency checker gives you a zero-install read, and we would rather you measure than take anyone’s word for a number, ours included.
Platform setup, including NinjaTrader preinstalled and configured, is covered on our NinjaTrader VPS page. If you are weighing providers rather than platforms, our futures VPS comparison ranks the field and discloses up front that we are one of the entries in it.
How we checked this
Worth stating plainly, because a lot of what is being published about E-nano right now is rewritten from the same press release.
Every contract figure on this page was read from CME Group’s own E-nano FAQ and its August 3 announcement, both in full rather than in summary. The multipliers, tick sizes, tick values, product codes, exchange listings, trading hours, settlement method, offset ratios and the block, BTIC and volume-discount exclusions are CME’s published numbers, not another site’s paraphrase of them.
The tick-value comparison, the price-resolution point and the commission arithmetic are ours. We derived them from CME’s spec table and checked that they hold across all four contracts rather than only the S&P 500 example. Where a figure is our calculation rather than CME’s, the copy says so.
Where something is unpublished, we say it is unpublished instead of estimating. Margins, broker commissions and prop firm equivalency rules all fall into that category as of writing. We would rather send you to CME and your broker for those than publish a number that turns out to be wrong, and we will update this page when they are announced.
We have not traded an E-nano contract, and neither has anyone else, because they have not listed yet. What we do bring to this is the adjacent part: we host NinjaTrader and other futures platforms for automated traders, and we spend a lot of time measuring execution paths and watching what breaks when a platform or a contract changes underneath a running strategy. That is where the automation section comes from.
Frequently Asked Questions
E-nano futures are CME Group equity index contracts listing on August 24, 2026, pending regulatory review, at one tenth the size of Micro E-mini futures and one hundredth the size of full E-mini futures. They cover the S&P 500, Nasdaq-100, Russell 2000 and Dow Jones Industrial Average, are financially settled, and trade nearly 23 hours a day on the same schedule as their larger counterparts.
Twenty-five cents on the E-nano S&P 500 and ten cents on the Nasdaq-100, Russell 2000 and Dow Jones contracts. That is one fifth of the equivalent Micro E-mini tick rather than one tenth, because CME set the E-nano tick at double the index-point increment while the multiplier fell by ten.
The multiplier is ten times smaller, so notional exposure and dollar risk per index point both fall by ten. The tick is twice as wide in index points, so each tick is worth one fifth as much and your price resolution is half as fine. The underlying index, settlement method and trading hours are identical.
NES for the S&P 500, NNQ for the Nasdaq-100, N2K for the Russell 2000 and NDOW for the Dow Jones Industrial Average. NES, NNQ and N2K list under CME; NDOW lists under CBOT.
NinjaTrader is one of two platforms CME named at announcement, alongside Robinhood, and its CEO is quoted in the launch release. Listing and platform enablement are separate steps, so confirm the symbols appear, that your data subscription covers them, and what commission tier applies before the first session.
CME has not published E-nano margin figures. Its FAQ directs traders to the margins page rather than quoting a number, so any specific figure circulating before launch is an estimate rather than a requirement. Check CME’s margins page at launch.
No broker has published commissions yet, which makes it the open question that decides everything. If a broker charges the same flat per-contract rate as on a Micro, you need five times as many ticks to cover it, so commission drag per unit of exposure roughly doubles. Ask whether your broker will price E-nano as its own tier.
Yes. CME allows E-nano positions to be offset against opposing positions in their counterparts at 10:1 against Micro E-mini futures and 100:1 against E-mini futures. Offsets are executed by asking your clearing broker to submit a request to the clearinghouse.
Unpublished as of writing. Firms maintain contract-equivalency tables that set how each contract size counts toward position limits, and none appear to have stated where E-nano sits. Ask your firm directly before the launch date rather than assuming a favourable ratio.
No. CME states that E-nano volume will not count toward its existing volume-based fee discounts. The contracts are also not eligible for block trading or BTIC.
They are financially settled against the Special Opening Quotation on the third Friday of the contract month, the same print that settles the E-mini and Micro E-mini. Only the nearest two quarterly months from the March, June, September and December cycle are listed at any time.
Not because of the contract size. E-nano solves a position-sizing problem, not an execution-speed one, and a smaller contract does not make a fill arrive sooner. Hosting matters for the same reasons it did before: automation that has to keep running while you are away and cannot afford a dropped connection, which is worth more than usual on a launch day when books are thin.
Confirm the four symbols exist and your data subscription covers them, confirm your commission tier, replace any hard-coded tick values in sizing or risk code, convert tick-denominated stops into index points and re-derive them, and check that your simulator carries the real E-nano tick rather than inheriting a Micro’s.
Contract specifications, product codes, settlement mechanics, offset ratios and exclusions come from CME Group’s published E-nano FAQ and its August 3, 2026 announcement. The tick-value and price-resolution comparisons are our own arithmetic from CME’s spec table. The launch is pending regulatory review, margins are unpublished, and broker commissions have not been announced, so verify current details with CME and your broker before trading. This is infrastructure and educational content, not trading or financial advice.
