MES vs ES is the first real sizing decision every futures trader makes on the S&P 500. Same index, same hours, same setups — but the Micro E-mini moves 1/10 the dollars per tick of the full E-mini, and on a funded account that difference is the line between a survivable losing day and a busted evaluation.
What is the difference between MES and ES?
ES is the E-mini S&P 500 futures contract with a $50 multiplier — each 0.25 tick is worth $12.50, one full point is $50. MES is the Micro E-mini S&P 500, sized at 1/10 of ES: $5 per point, $1.25 per tick. Same index, same tick size, same market hours — 10 MES equals 1 ES in exposure. Start on MES, graduate to ES once expectancy is proven.
- →ES = $12.50/tick, MES = $1.25/tick. Everything else is identical.
- →10 MES = 1 ES in dollar exposure and P&L.
- →Start on MES until expectancy is positive over 40+ days.
- →MES has lower margin and fits small drawdowns cleanly.
- →Every major prop firm supports both — size limits scale with account.
- →Micros let you scale in / out in 10% steps — huge for consistency-rule accounts.
MES vs ES Side-by-Side
Both contracts settle to the same underlying index — S&P 500 — trade on the same CME Globex venue, and share identical market hours. The only differences that matter are dollars per tick, notional exposure, and margin.
| Spec | ES (E-mini) | MES (Micro) |
|---|---|---|
| Multiplier | $50 × index | $5 × index |
| Tick size | 0.25 index points | 0.25 index points |
| Tick value | $12.50 | $1.25 |
| Value per point | $50 | $5 |
| Notional (@ index 6,000) | ~$300,000 | ~$30,000 |
| Exchange symbol | ES | MES |
| Trading hours | Sun 6pm – Fri 5pm ET | Sun 6pm – Fri 5pm ET |
| Ratio | 10 MES = 1 ES | |

What the Dollar Difference Actually Feels Like
Numbers on a spec sheet don't sting. Real P&L does. Here's what the same trade looks like on each contract:
| Move | 1 MES | 1 ES | 10 MES |
|---|---|---|---|
| 1 tick (0.25 pt) | $1.25 | $12.50 | $12.50 |
| 1 point | $5 | $50 | $50 |
| 4 points | $20 | $200 | $200 |
| 10 points | $50 | $500 | $500 |
| 40 points | $200 | $2,000 | $2,000 |
Practical read: an 8-point stop on 1 ES is a $400 loser. The same stop on 1 MES is $40. On a $50K evaluation with a $2,500 drawdown, that difference decides whether one bad idea ends the account.
Margin: Why MES Is a Small-Account Weapon
CME initial margin on ES typically sits in the $12,000–$20,000 range (varies monthly). MES is 1/10 that. But futures prop firms don't use CME initial — they set day-trade margin per contract, which is what actually gates your sizing.
Typical intraday day-trade margin ranges you'll see across firms:
- ES: ~$500 – $1,500 per contract intraday (higher near close & overnight).
- MES: ~$40 – $100 per contract intraday.
On a $50K evaluation with a $2,500 max drawdown, one ES is realistically the largest position you should carry — a 4-point stop hits 8% of your drawdown. With MES you can run 3–5 contracts with the same total risk and still leave headroom for a second trade. Micros make the math on small evaluations actually workable.
MES vs ES on a Funded Account
Every major futures prop firm supports both contracts. The differences that matter for a funded trader are contract limits (how many you can carry per account size), how micros count against those limits, and how the drawdown type interacts with your position.
| Firm | MES / ES Support | Micro counting | Best fit |
|---|---|---|---|
| FundedNext Futures | Both, all plans | Micros count fractional vs limit | Flex for news-driven MES scalps — see the FundedNext review. |
| Tradeify | Both, all plans | Micros count fractional | Static plans + MES for consistency-friendly ladders. See the Tradeify review. |
| Apex Trader Funding | Both, all plans | Micros count fractional (check current rulebook) | EOD drawdown + MES for small evaluations. See the Apex review. |
Contract limits and how micros count toward them vary by firm and account size — check the current rulebook before assuming.
When to Trade MES vs When to Trade ES
- You're on a small evaluation ($25K–$50K) with a tight drawdown.
- You're still building expectancy — under 40 clean trading days.
- Your setup requires wider stops (10+ points on ES).
- You want to scale in / out in 10% increments (5 MES, 4 MES, 3 MES...).
- You're managing multiple funded accounts through a copier and need finer per-account granularity.
- You're consistently running 10+ MES — consolidation cuts fees.
- Your expectancy is positive over 40–60 days and 1 ES risk fits inside your daily loss limit with room.
- You need tighter fills — ES typically has the deepest book of any US equity index future in RTH.
- You're on a larger funded account ($100K+) with commensurate drawdown.
MES vs MNQ: Which Micro Should You Trade?
A lot of new futures traders bounce between MES and MNQ without picking one to master. Quick comparison for prop firm sizing:
| Spec | MES | MNQ |
|---|---|---|
| Tick value | $1.25 | $0.50 |
| Value per point | $5 | $2 |
| Typical daily range | ~40–60 points | ~200–400 points |
| Typical daily $ range / contract | ~$200–$300 | ~$400–$800 |
| Vibe | Slower, cleaner structure | Faster, wider swings |
MES is the calmer contract — better for learning execution and holding through structure. MNQ pays more per unit of time but requires tighter risk. On a small evaluation, most traders should start on MES.
Common MES / ES Mistakes
- Skipping straight to ES. Every loser is 10x the tuition. Almost every blown funded account I've reviewed started with someone sizing ES before they were ready.
- Running 15+ MES instead of a smaller ES. Round-turn commissions add up fast. Once you're consistently over 10 micros, consolidate.
- Treating MES like play money. Micros feel cheap but a bad 10-point stop on 5 MES is still $250. Size to the setup, not to the "it's only micros" feeling.
- Mixing MES and ES in the same account. Confusing when you're calculating drawdown headroom mid-session. Pick one per account, per session.
- Forgetting overnight margin. Day-trade margin flips to overnight rates before close. Sizing that fits at 10:30 ET might not fit at 15:55 ET.
MES + Copy Trading: The Small-Account Scaling Path
The reason micros exist for a funded trader isn't tiny size — it's clean per-account granularity when running a copier across multiple funded accounts. A 1-lot ES signal copied to five $50K accounts is 5 ES of firm-wide exposure at open — that's real news-risk. The same signal at 5 MES per account is 2.5 ES of exposure but distributed and scalable per-account.

Round-turn commissions vary by platform and prop firm, but the pattern is stable. Assume a typical prop-firm cost of ~$1.00 round-turn on MES and ~$4.00 on ES (real numbers vary; check your firm):
| 100 trades | 1 MES / trade | 1 ES / trade | 10 MES / trade |
|---|---|---|---|
| Commissions | ~$100 | ~$400 | ~$1,000 |
| Exposure | 1x | 10x | 10x |
1 ES is cheaper than 10 MES for identical exposure. Rule of thumb: below 5 micros, stay on MES; at 10 micros consolidate to ES.
MES vs ES FAQ
What is the difference between MES and ES?+
ES is the E-mini S&P 500 futures contract; MES is the Micro E-mini S&P 500, sized at 1/10 of ES. ES has a $50 multiplier ($12.50 per 0.25 tick), MES has a $5 multiplier ($1.25 per 0.25 tick). Same underlying index (S&P 500), same market hours, same tick size — only the notional exposure and dollars per tick change.
What is the tick value of MES?+
MES moves in 0.25-point ticks worth $1.25 each. One full S&P point is $5. A 10-point move on 1 MES is $50; the same move on 1 ES is $500.
What is the tick value of ES?+
ES moves in 0.25-point ticks worth $12.50 each. One full S&P point is $50. A 10-point move on 1 ES is $500; a 40-point move is $2,000 per contract.
How many MES equal one ES?+
10 MES = 1 ES in exposure. If your risk plan calls for 1 ES but you want finer sizing, 10 MES gives the same P&L with the ability to scale in and out in 10% increments instead of all-or-nothing.
Is MES cheaper than ES on prop firm accounts?+
MES has a much lower day-trade margin (typically ~$40–$100 intraday vs $500–$1,500 for ES depending on firm and time of day) and moves 1/10 the dollars per tick. On evaluations with a small drawdown or a strict consistency rule, MES lets you trade the same setup without one loser blowing the account.
Should beginners trade MES or ES?+
Start on MES. The setup, execution, and mindset are identical, but a $50 loss on a 10-point stop hurts less than $500. Once you've booked 20+ green trading days on MES with a positive expectancy, size up to ES or run multiple MES contracts.
Can I trade MES on Apex, Tradeify, and FundedNext?+
Yes. Every major futures prop firm — Apex Trader Funding, Tradeify, and FundedNext Futures — supports both MES and ES on evaluation and funded (PA) accounts. Contract limits scale with account size, and micros usually count fractionally against your per-account position limit.
What is the contract size of MES vs ES?+
ES is $50 × the S&P 500 index. At an index level of 6,000 that's a notional exposure of $300,000 per contract. MES is $5 × the index — $30,000 notional at the same level. Micros exist specifically to let retail and prop firm traders scale exposure without $300K+ per lot.
Does MES move exactly with ES?+
Yes. Both settle to the same S&P 500 index and trade nearly tick-for-tick. MES can occasionally show a wider bid/ask spread during thin overnight sessions, but during RTH (9:30–16:00 ET) they track each other cleanly.
When should I graduate from MES to ES?+
Two conditions: your expectancy on MES is positive over at least 40–60 trading days, and 1 ES risk fits inside your account's daily loss limit and trailing drawdown with room to spare. If you're routinely running 10+ MES, the sizing is already ES — just consolidate. If you're running 1–3 MES and it stings, you're not ready.
