Futures Position Sizing: Tick Value for ES, MES, NQ, MNQ

You found a clean setup, the stop is where the chart says it should be, and then the order ticket asks for a quantity. You type 1, because 1 is the smallest number, and you have no idea whether you just risked $30 or $300. Contract size is

You found a clean setup, the stop is where the chart says it should be, and then the order ticket asks for a quantity. You type 1, because 1 is the smallest number, and you have no idea whether you just risked $30 or $300.

Contract size is not a feeling. It is your dollar risk divided by stop distance times what one point is worth, and the point value is the one number you must look up.

A tick is a price step and a point is four of them

Futures prices move in fixed steps called ticks (the smallest increment the exchange allows). A point is a full index point, and on the contracts below one point equals four ticks.

CME states the contract terms on each product's own specification page. The E-mini S&P 500 specs set a $50 multiplier and a minimum tick of 0.25 index points, which is $12.50 per contract. The Micro E-mini S&P 500 specs list a $5 multiplier with the same 0.25 tick, so $1.25.

The Nasdaq-100 follows the same pattern. The E-mini Nasdaq-100 page gives $20 per point and a 0.25 tick, worth $5.00, and the Micro E-mini Nasdaq-100 specs give $2 per point, worth $0.50 per tick. CME's own micro E-mini FAQ describes the micros as one tenth the size of their E-mini counterparts.

Specs get amended, so read the current page for the contract you trade before you trust a blog table, including this one.

The formula has four inputs and one rounding rule

Contracts = risk budget in dollars ÷ (stop distance in points × dollars per point). Then round down, never up.

Rounding down is the part people skip. If the answer is 2.6, you trade 2, because 3 is a different risk than the one you chose. If the answer is 0.7, the trade does not fit your budget at that stop distance and the honest options are a smaller trade idea or no trade.

This is the same mechanical logic as the pip-based example in our risk of ruin and position sizing guide. Only the point value changed. The risk budget itself should come from a plan you wrote when you were calm, not from how confident you feel at the ticket.

Worked examples show why micros exist

All numbers below are hypothetical. They illustrate the arithmetic and are not a trade idea or a suggestion about how much to risk.

Say the budget for one trade is $200.

Contract	Stop	Risk per contract	Contracts that fit
ES	6 points (24 ticks)	6 × $50 = $300	0 (budget too small)
MES	6 points (24 ticks)	6 × $5 = $30	6 ($180 total)
NQ	40 points (160 ticks)	40 × $20 = $800	0
MNQ	40 points (160 ticks)	40 × $2 = $80	2 ($160 total)

Notice what happened on ES. One contract at that stop risks more than the whole budget. The setup is fine, the instrument is too coarse for the size you decided on.

Notice what MES does on the second line. Six contracts risk $180, and you can still scale to five or seven if the plan calls for it. That granularity is the entire value of a micro: it lets the quantity track the risk instead of the other way around.

The unit mix-up that costs real money

The classic error is typing a stop in ticks when you meant points, or the reverse. On MES, 10 points is $50 of risk per contract. Ten ticks is 2.5 points, or $12.50. That is a fourfold difference from one misread word.

Platforms differ. Some ladders and bracket order panels default to ticks, some charts quote in points. Before you click, convert the stop to dollars per contract and say the number out loud: "this stop costs me $30 a contract."

The stop is not the whole loss

A stop order is a trigger, and a stop-market order can fill through your level. Our post on why a stop order fills away from the level you set walks through the mechanics.

For sizing, the useful part is simple. Say 6 MES contracts stop out one tick through the level. That is 6 × $1.25 = $7.50 extra, on top of the $180. Your $200 budget absorbed it. If you had sized to the penny at $200, the loss would have exceeded the budget, which is why many traders leave a gap between the budget and the sized risk.

Fees count the same way. Commissions and exchange fees are charged per contract, and I am deliberately not quoting a figure because they vary by broker and change. What does hold is the shape: a micro contract carries a tenth of the dollar move but not a tenth of the per-contract cost, so the smaller your stop, the bigger the share fees take of your risk. Pull your broker's real fee schedule into the formula before deciding a tight scalp is worth it.

The contract you can trade is set by your stop distance and your budget. If the contract is too big for the trade, the trade is not wrong. The contract is.

— The Tradoki desk note

Micros let the stop come first

Many traders choose a contract size first and then squeeze the stop to fit the dollars they can tolerate. That is backwards. A stop that sits inside normal noise gets hit for no reason, and where a volatility stop actually comes from matters more than which contract you happen to own.

The better order is: structure decides the stop, the stop decides the points at risk, the budget decides the quantity. Micros make the third step workable for smaller risk budgets. Whether futures belong in your plan at all is a separate question, and leverage cuts both ways.

Prop firm accounts add a second constraint. A fixed dollar daily limit means your per-trade budget is effectively a fraction of it, and our explainer on how daily loss limits and max loss limits reset shows how quickly two or three full-size losses can touch it. Sizing in micros is one way people keep a normal losing streak from becoming an account-ending one. It is not a guarantee of anything.

Two more checks before the first order

Know which contract month you are on. Quarterly contracts roll, and the symbol you sized against last week may not be the one that is liquid today, which our guide to futures rollover dates and continuous contracts covers in detail.

Then run the whole thing on a demo or simulator account first. Type the stop, read the dollars, check the filled loss against the sized loss for a few weeks. That log is more honest than any calculator.

● FAQ

What is the tick value of MES and ES?

Both trade in 0.25 index point ticks. On MES, CME sets the multiplier at $5 per index point, so one tick is $1.25. On ES the multiplier is $50, so one tick is $12.50. The micro is one tenth of the size and the tick is one tenth of the value.

How many MES contracts equal one ES contract?

Ten, because MES is priced at one tenth of the E-mini. Ten MES contracts carry the same dollar move per index point as one ES contract. Fees, margin and fills are not identical, so ten micros is a comparison of exposure, not a perfect substitute.

How do I calculate futures position size from a stop loss?

Take the dollar amount you are willing to lose, divide it by stop distance in points times the dollar value of one point, then round down. If the answer is below one contract, the trade does not fit the budget at that stop distance. Widening the risk budget to get a whole contract is the usual way this goes wrong.

Is a point the same as a tick in futures?

No. On the S&P 500 and Nasdaq-100 futures covered here, a tick is a quarter of an index point, so one point is four ticks. Mixing the two up quadruples or quarters your intended risk, which is why it pays to type the stop in points and confirm it in dollars before sending the order.

Should a small account trade micros instead of E-minis?

The sizing formula decides that, not a rule of thumb about account size. If your risk budget cannot cover one E-mini at your stop distance, the micro lets you take the same setup at a size that fits. That is a statement about arithmetic, not a suggestion that any account should trade futures.
