Scalping Futures (MNQ, MES and ES): Costs, an Example Rule Set and Prop Firm Rules

Scalping futures means taking many short trades for small targets, often a few points on MES or ES, held for seconds to minutes. Because each win is small, costs per round turn and slippage decide whether a scalping method makes money at all. Below is the cost math for MNQ, MES and ES, an example rule set, the prop firm rules that matter, and a testing plan.

What is scalping in futures?

A scalper aims to capture small, frequent moves inside the day. Typical targets are a few points on the S&P 500 contracts and somewhat more on Nasdaq, which moves more points per day. Trades last from seconds to a few minutes. A busy scalper may take ten or more trades in a session.

The appeal is clear: quick feedback, small stops, little time exposed to surprise news. The catch is that you pay costs on every trade, and you pay them far more often than a swing trader does.

What does a round turn cost?

A round turn is a full trade: in and out. Its cost is the commission and fees on both sides, plus any slippage on market or stop orders. Commissions, exchange fees and clearing fees vary by firm and broker, so check your fee schedule.

Example figures: $0.70 per side for a micro contract and $2.50 per side for a mini, all fees included. That makes $1.40 and $5.00 per round turn.

Contract	Tick value	Example round turn	Cost in ticks	Cost in points
MNQ	$0.50	$1.40	2.8 ticks	0.70
MES	$1.25	$1.40	1.12 ticks	0.28
ES	$12.50	$5.00	0.4 ticks	0.10

Look at the last column. Ten MES contracts carry the same exposure as one ES contract, but at these example rates they cost $14 per round turn against $5. Micros are the right tool for small accounts and tight risk. Just know that a micro scalper needs a slightly larger edge per trade. For contract sizes, see micro vs mini futures.

An example scalping rule set for MES

This is an illustration to test, not a proven edge. It trades with the morning trend and uses session VWAP as the bias.

1. Window: 9:45am to 11:30am New York time only. Skip it when major data is due inside the window, such as a 10am release.
2. Bias: longs only when price is above session VWAP and VWAP is rising. Shorts only in the reverse case.
3. Setup: after a new session high, wait for a pullback of 3 to 6 points that stays above VWAP.
4. Entry: a buy stop 1 tick above the high of the first 1 minute candle in the pullback that closes above its open.
5. Stop: 1 tick below the pullback low. Skip the trade if that is wider than 3 points.
6. Target: a limit order 4 points above entry.
7. Time stop: exit at market if neither stop nor target fills within 10 minutes.
8. Daily limits: six trades at most. Stop after three losses or at your personal daily stop.

If you are new to VWAP, read the VWAP trading strategy guide first.

When this rule set fails

• Choppy days. Price crosses VWAP again and again, and pullbacks fail. The bias rule cuts some of this but not all.
• Fast markets. Slippage grows to several ticks, which can erase the edge.
• Overtrading. Extra trades outside the rules add costs without adding edge.
• Tilt. A quick loss invites a quick revenge trade. The three loss rule exists for this.

Worked example: how costs move the break even

Example figures, one MES contract, a 4 point target and a 3 point stop. Assume one tick of slippage on the stop entry and on the stop exit, none on the limit target.

• Gross win: 4 × $5 = $20. Net win: $20 minus $1.25 entry slippage minus $1.40 round turn = $17.35.
• Gross loss: 3 × $5 = $15. Net loss: $15 plus $1.25 entry slippage plus $1.25 exit slippage plus $1.40 = $18.90.

Break even win rate = 1 ÷ (1 + reward to risk)

Before costs, reward to risk is 4 ÷ 3, about 1.33. Break even is 1 ÷ 2.33, about 42.9%. After costs, it is $17.35 ÷ $18.90, about 0.92. Break even rises to 1 ÷ 1.92, about 52.1%. Costs alone added over nine percentage points.

At a 55% win rate, expectancy is 0.55 × $17.35 minus 0.45 × $18.90, which is about $1.04 per contract per trade. At 50%, it is a loss of about $0.78. That thin margin is why scalpers obsess over fills and fees.

How this fits prop firm rules

Commissions count toward your daily loss limit and drawdown on most accounts. Example figures: a $1,000 daily loss limit, a personal daily stop of $500 and $125 risk per trade. Each MES contract loses $18.90 at the stop, so 6 contracts risk $113.40. Three losses cost $340.20, inside the $500 stop.

The ES contract does not fit this plan. A 3 point stop is $150 per contract, plus about $30 in slippage and fees, so one contract already risks $180. Six MES give finer control at a little over half the exposure of one ES.

Consistency rules usually favor scalpers, since profit spreads over many small trades. The danger is one oversized day that becomes most of your total. Keep size fixed. Some firms also restrict very short holding times, high trade counts or trading around news. Rules vary by firm; check each firm’s page on PropFirmXchange. See the consistency rule guide, compare futures prop firms and use find an account to filter by budget.

How to test a scalping method

1. Use tick or 1 minute data. Higher timeframes hide the order of highs and lows inside a bar.
2. Count a limit target as filled only if price trades through it by a tick, not if it merely touches.
3. Charge full round turn costs and at least one tick of slippage on every stop order.
4. Rerun the test with double the slippage. If the result turns negative, the edge is too thin to trust.
5. Collect at least 200 trades, since each one carries little information.
6. Forward test on a simulator and log every fill against the price you planned.

Questions traders ask

Is MNQ or MES better for scalping?

MES usually costs less per round turn in ticks and moves fewer points. MNQ moves more, so targets and stops need more points. Test both with your own costs.

How many trades a day should a scalper take?

As many as the rules produce, and no more. Set a daily cap in advance so costs and fatigue do not grow unchecked.

Do prop firms allow scalping?

Many do, within limits. Some restrict very short holds or certain automated styles, so read each firm’s rules before you start.

Futures trading carries a high risk of loss, and frequent trading adds costs that make losses more likely. Most prop firm accounts are simulated. Nothing here is financial advice.
