Scalping means taking many short trades for small moves — often a few pips or a few points — and holding each one for minutes. Done well, it gives a large sample of trades quickly. Done badly, it’s the fastest way to hand your account to the spread.
Start with the cost math
Before any setup, calculate what each trade costs. Suppose EUR/USD has a 0.2-pip raw spread plus a commission equivalent to 0.7 pips round turn — about 0.9 pips in total.
| Target | Cost as % of target |
|---|---|
| 5 pips | 18% |
| 10 pips | 9% |
| 20 pips | 4.5% |
A 5-pip scalper gives up almost a fifth of every winner to costs, and costs also enlarge every loser. That’s why serious scalpers trade only the most liquid instruments — EUR/USD, USD/JPY, ES, NQ, MES, MNQ — at their busiest hours.
Run your own numbers with the pip value calculator and your broker’s actual spread.
The setup: trend pullback scalp
A simple, testable scalping model with three timeframes:
- Direction (15-minute): price above the 50 EMA and making higher highs = longs only. Below = shorts only.
- Setup (5-minute): wait for a pullback to the 20 EMA.
- Trigger (1-minute): enter when a 1-minute candle breaks the high of the prior candle (for longs) after the pullback.
Stop: below the 1-minute pullback low, plus spread. Target: 1.5R, or the most recent 5-minute swing high if closer. Time stop: if the trade hasn’t reached 1R within 15 minutes, exit at market.
A worked example on MES
The 15-minute chart is above a rising 50 EMA. At 9:52 a.m. MES pulls back to the 20 EMA on the 5-minute chart near 5,431.00.
- Trigger: a 1-minute candle breaks the prior candle’s high; the buy stop fills at 5,432.25.
- Stop: below the 1-minute pullback low at 5,429.75 — 2.5 points, or $12.50 per MES contract ($5 per point).
- Size: risking 0.5% of a $10,000 account ($50) allows four MES contracts ($50).
- Target: 1.5R is 3.75 points, 5,436.00. Commissions of roughly $1–$2 per contract round turn are a meaningful share of a $75 winner — include them in your journal.
- Time stop: flat by 10:07 a.m. if 1R hasn’t been reached.
Scalping on futures vs forex
| Forex majors | Micro index futures | |
|---|---|---|
| Cost | Spread + commission, varies by broker and hour | Fixed commission + 1-tick spread on liquid contracts |
| Sizing | Very fine (0.01 lots) | Whole contracts ($5/point on MES) |
| Best hours | London open, London–NY overlap | First 90 minutes after 9:30 a.m. |
| Volume data | Broker tick volume | Real exchange volume |
When to scalp
Scalping depends on volume. The best windows are:
- Forex: London open and the London–New York overlap (about 3:00 a.m. to noon New York time). See the best time to trade forex.
- Index futures: the first 90 minutes after the 9:30 a.m. cash open.
Avoid the minutes around high-impact news. Spreads widen and slippage can turn a 5-pip stop into 15.
Risk rules for scalpers
Fast trading magnifies emotional mistakes, so the rules must be stricter than for slower styles:
- Risk per trade: 0.25%–0.5% of the account.
- Maximum trades per day: fixed in advance.
- Daily loss limit: stop after three losses or −1.5%, whichever comes first.
- No adding to losers. Ever.
The position size calculator handles sizing; the drawdown calculator shows why the daily limit matters.
Common scalping mistakes
- Trading dead hours. Spreads are wider and moves are smaller in the Asian afternoon and US lunch hour.
- Moving the stop. On a 1-minute chart, “giving it room” quickly turns a 5-pip loss into 20.
- Ignoring commissions in the journal. Track net results, not gross. Many scalpers discover they are profitable before costs and losing after them.
- Overtrading after a loss. The setup didn’t change because you lost; your judgment did.
A scalper’s daily routine
- Before the session: mark the prior day’s high and low, the overnight range and scheduled news.
- First 30 minutes: observe direction on the 15-minute chart; take only setups in that direction.
- During the window: stop at your trade limit, your daily loss limit or the end of the window — whichever comes first.
- After the session: log every trade with net result, screenshot and whether it matched the rules.
Test before trading live
Run the strategy on a demo account or in replay for at least 100 trades and log net R per trade. A backtesting tool with bar replay makes this much faster.
Frequently asked questions
Is scalping profitable?
Scalping can be profitable, but trading costs take a much larger share of each trade than in slower styles. A setup that works on paper often loses money once spread, commission and slippage are included, so cost testing comes first.
What is the best timeframe for scalping?
Most scalpers execute on 1-minute charts and use a 5- or 15-minute chart for direction. Lower timeframes increase noise and cost per trade relative to the move.
Can you scalp in a prop firm challenge?
Many firms allow scalping, but some restrict very short holding times, tick scalping or trading around news. Check the rules, then use small risk per trade and a strict daily stop so the firm's daily loss limit is never close.
Is scalping better on forex or futures?
Both work on the most liquid instruments. Futures such as ES and MES have transparent, fixed commissions and real volume; forex majors offer flexible sizing. Compare your total cost per trade against your average target on each.
How many trades should a scalper take per day?
Set a fixed maximum — often 3 to 8 trades — and a daily loss limit. Unlimited trade counts are the main reason scalpers give back their gains.
