The idea
Momentum day traders watch for stocks and futures that move hard right after the open. The first time such a move pauses and pulls back to the 9-period EMA, it often resumes: buyers who missed the first push are waiting for exactly that dip.
The scalp buys a break of the previous candle's high after that first touch, with a tight stop under the pullback and a quick target, usually 1.5 to 2R.
Watch it play out
Step by step
The rules
Setup
- A strong, clean move in the first minutes of the session, with price above a rising 9 EMA.
Entry
- On the first pullback that touches the 9 EMA, buy when a candle closes above the previous candle's high.
Stop-loss
- Just under the pullback's low.
Target
- 2R, or the high of the move.
Filters that help
- Only the first pullback; skip later ones.
- Liquid markets only: spreads eat scalps on thin stocks.
Why it can work
The 9 EMA tracks a strong intraday move closely, so the first pullback to it is shallow and the stop close. The first pullback is favoured because the move is still fresh; later pullbacks come as the move tires.
Scalps also keep exposure short. The trade is open for minutes, so a sudden reversal later in the day cannot hurt it, and the small stop lets a trader size up while risking the same amount. The price of that is that costs, spreads and slippage take a far larger share of each trade than in slower strategies, and a scalper who is slow to act loses the edge entirely.
Worked example
A stock runs from $25.05 to $25.75 in the first eight minutes. It pulls back to the 9 EMA, the pullback low is $25.54, and a candle closes above the previous high at $25.72: buy, with the stop at $25.52.
Risking $100, the 20-cent stop allows 500 shares. A 2R target sits at $26.12.
When it works, when it fails
Works best
On stocks and futures with real news and volume, in the first hour.
Struggles
On slow days, when the 'move' is too small to matter, and when the first pullback turns into a reversal. Costs weigh heavily on scalps.
Common mistakes
- Taking the third and fourth pullbacks as if they were the first.
- Widening the stop when the pullback goes deeper.
- Trading illiquid stocks where the spread is a large part of the target.
Variations
- 20 EMA version
- The same first pullback rule with a 20 EMA on a five-minute chart, for slower moves and slightly wider stops.
What the evidence says
Evidence: Popular, untestedWidely used, but no rigorous public testing. An idea to test yourself.
The 9 EMA scalp is a staple of day trading courses, with no rigorous public study after costs. Intraday trading is expensive and most individuals who do it lose money, according to regulator studies.
If you test it, include realistic spreads and slippage: on scalps they decide the result.
Questions
- What target suits a scalp?
- Small and quick: 1.5 to 2R, or the high of the move. Scalps rely on getting out while the momentum lasts; holding for a home run usually turns winners into scratches.
- How many trades does it give a day?
- Usually only a few, because it needs a strong opening move and only takes the first pullback. Days without a clean move offer no trade.
- Why the 9 EMA for scalping?
- It follows fast intraday moves closely, so pullbacks to it are shallow and the stop stays small. The 9 is convention; 8 or 10 behave much the same.
- Why only the first pullback?
- Because the move is freshest. Each later pullback comes as the move ages and is more likely to be the turn.
- Which timeframe suits the 9 EMA scalp?
- One and two minute charts for scalping, five minutes for a slower version.
