Micro vs Mini Futures: How to Choose Your Contract Size

A Micro futures contract is one tenth the size of its E-mini (or standard) counterpart, so every point, tick and dollar of profit or loss is one tenth as large. Choose micros when one mini at your normal stop would risk more than your planned loss per trade; choose minis when your plan regularly needs ten or more micros of the same market.

That is the whole decision in two sentences. The rest of this guide shows the numbers side by side, runs the test on a $50K prop account for four popular markets, and covers what changes at prop firms, where micros and minis often share one contract limit.

Micro vs mini in one table

All figures are from CME Group’s contract specifications. Point value is what a full one-point move (or a $1 move for oil and gold) is worth on one contract.

The tick size is the same for both sizes; only the multiplier changes. CME’s equity micros trade the same hours as the E-minis on CME Globex (Sunday to Friday, 6:00 p.m. to 5:00 p.m. ET), follow the same index and show the same price. Micro WTI crude is cash-settled, while the standard CL contract is physically delivered, which matters only if you hold into expiry. Prop accounts normally close you out long before that. The full list, including Dow and Russell, is in futures tick values.

The one test: does one mini fit your risk per trade?

Size comes from the stop, not from the account size. The formula is the same for every contract:

Contracts = risk per trade ÷ (stop in points × point value)

Take a $50K prop account with $2,000 of room to the maximum loss limit, and a plan to risk $200 per trade (ten full losses before the line). Here is the test on four markets with typical stops:

In three of the four markets a single mini would double the plan. Trading it anyway means either a stop that is too tight for the setup or a loss twice as large as intended. Micros remove that choice. Crude oil is the edge case: one CL fits exactly, but there is no way to go smaller if the stop needs to be 25 cents, while MCL can drop to 8 contracts ($200) and stay on plan.

The free futures position size calculator runs this for any stop and contract, and position size for NQ, ES and gold walks through more examples.

Why many prop traders start with micros

Finer steps

Rounding down costs less with small steps. With a $300 budget and a 20-point Nasdaq stop, one NQ risks $400, so you trade zero. MNQ risks $40 each, so 7 MNQ puts $280 at risk, within $20 of the plan.

Partial exits

One NQ is all-in or all-out. Ten MNQ let you take half off at the first target and manage the rest. Selling 5 MNQ at +20 points banks 5 × 20 × $2 = $200 while the other five stay open.

Room on a small drawdown

Evaluation drawdowns are small next to the headline account size. A $2,000 maximum loss is four full NQ losses at a 25-point stop, or forty losses of a single MNQ. Micros let you choose how many losses your plan can absorb.

A cheaper way to learn

Mistakes cost one tenth as much. That makes micros a sensible size for testing a new setup or coming back after a break, before the numbers matter.

When minis make more sense

Micros are not lower risk per point once you trade more of them: ten MNQ move exactly like one NQ. Once your plan regularly calls for ten or more micros of the same market, look at the mini for two reasons:

• Fees are charged per contract. Ten micros means ten commissions and ten sets of exchange fees. On many fee schedules a micro’s fee is well above one tenth of the mini’s, so the same exposure costs more in micros. Compare your own schedule: cost of 10 micros versus cost of 1 mini, per round turn.
• Fewer orders to manage. One order instead of ten is simpler to place, modify and journal.

Many traders mix the two: a mini or two for the bulk of the position and micros to fine-tune the risk. With a $1,000 budget and an 18-point NQ stop, 2 NQ ($720) plus 7 MNQ ($252) puts $972 at risk.

Micros and minis at prop firms

Most futures prop firms let you trade both sizes, but the contract limit usually covers both. At some firms micros count at a 10:1 ratio against minis. Topstep, for example, states that “micros and minis count at a 10:1 ratio” in the Trading Combine and lists maximum positions of 5 minis or 50 micros on a $50K account, 10 or 100 on $100K and 15 or 150 on $150K (checked 19 October 2026).

Under a 10:1 rule, 3 NQ and 20 MNQ count as 5 minis, already at the $50K limit. Other firms set separate micro limits, use scaling plans that grow with your balance, or apply different ratios, so check your firm’s current rules for your exact plan. The prop firm rules cheat sheet links to each firm’s official pages.

Fees also work differently in prop accounts: some firms include commissions in the evaluation price, others pass through per-contract fees that count against your daily loss limit and drawdown. If fees count against your limits, ten micros reach them faster than one mini.

Common mistakes with micro and mini sizes

• Logging the wrong symbol. A 30-point win on 2 MNQ is 30 × $2 × 2 = $120. Recorded as NQ, the journal shows $1,200. One wrong letter turns a 10× error into your statistics.
• Thinking micro means safe. Thirty MNQ is three NQ of risk. The size of each contract matters less than the total.
• Sizing from the account, not the drawdown. A $50K evaluation with $2,000 of room behaves like a $2,000 account for sizing. See trailing drawdown vs daily loss limit.
• Forgetting the even smaller size. CME also lists E-nano equity contracts, one tenth of a micro’s multiplier. They are covered in E-nano futures explained; check whether your platform and firm support them.

A simple rule for moving up a size

Size changes are where many plans fall apart, so make the rule mechanical and write it down before you need it:

1. Start with micros at a fixed risk per trade, for example $200.
2. Move up only on a schedule you set in advance (say, monthly), never mid-session.
3. Increase risk in small steps, for example $200 to $250, and stay in micros.
4. Switch to the mini only when your normal stop needs ten or more micros at the new risk.
5. If the drawdown room shrinks, size back down by the same rule.

These numbers illustrate the arithmetic; they are not a recommendation. Your size depends on your strategy, account and firm’s current rules.

Keep your size honest in your journal

Size drifts quietly. A journal that knows each contract’s point value shows it: risk per trade in dollars, the size you planned versus the size you traded, and whether those extra micros came after a loss. In TJ every trade is logged with its symbol, so MNQ and NQ are valued correctly, and Prop guard keeps your firm’s daily limit and maximum loss beside your open risk. Import your fills from your platform with the trade import guide or log them by hand.
