A scalp is a very short-term trade designed to take a small move in price, then exit quickly. The target is measured in ticks or pips rather than big swings, and the holding time is usually seconds to a few minutes.
To scalp is to open and close positions rapidly, often many times in one session. The trader is trying to stack lots of small, relatively high-probability gains while keeping losses small and rare.
What traders mean by a scalp
People use scalp in a few ways. As a noun: a quick, small profit on a trade. As a verb: to scalp a market means to trade for those tiny moves repeatedly. The related term scalper is the trader who does it, and scalping is the overall approach.
Scalps are most common in very liquid markets where the spread is tight and prices update constantly: major FX pairs, index futures, large-cap shares and heavily traded crypto pairs. Because the per-trade profit is small, costs and execution quality matter a lot. If the spread is wide or fills are slow, the edge can disappear.
How a scalp trade is planned and executed
A typical plan sets three things up front: the entry trigger, a tight stop, and a modest exit target. Many scalpers aim for a 1:1 or slightly better risk-to-reward ratio, counting on a higher hit rate rather than big winners.
Example: a liquid share is quoted 100.00 to 100.02. A trader buys at 100.02 after seeing buyers step up, places a stop at 99.97, and looks to sell at 100.05. If filled, the gross gain is 3 cents per share, the risk was 5 cents, and both are before commissions and fees. Multiply by size and repeat this setup through the session. In FX, the same idea might target 2 to 4 pips, with stops set just beyond the recent micro swing.
Order choice depends on the setup. Limit orders can help control entry price, especially if you are placing liquidity. Market orders prioritise speed when the price is moving and you do not want to miss the fill. Traders who read the order book watch how bids and offers refresh, how depth stacks up, and whether trades go through at the bid or the offer. That flow helps time entries and exits.
Scalps can be with the trend or countertrend. With-trend scalps often buy brief dips in an up move or sell quick pops in a down move. Countertrend scalps try to fade stretches when price jumps too far too fast, then snaps back.
When and where scalps tend to work
Scalps show up in two broad conditions. The first is high activity with strong liquidity: the opening minutes of cash equity sessions, overlaps in global FX hours, futures rolls, and busy crypto venues. Rapid quoting and tight spreads give more chances to enter and exit cleanly.
The second is range-bound trade where price keeps bouncing between nearby levels. If the range is wide enough compared with the spread and fees, short mean-reversion scalps can work. If the range is too tight, costs will eat the gains.
News can be a double-edged sword. Volatility creates opportunity, but slippage becomes more likely and spreads can widen. Many scalpers either stand aside into major announcements or switch to very conservative size until the market settles.
Tools and signals scalpers use
- Very short charts such as tick, one-second or one-minute bars to see micro swings and the immediate context.
- Level 2, time-and-sales and footprint-style views to watch queue position, trade aggressor and where trades are hitting.
- Price references like VWAP, session high and low, opening range and round numbers that often act as magnets or stall points.
- Simple momentum or mean-reversion cues. For example, a quick dip below VWAP with buyers stepping back in, or a brief overbought print on RSI that reverses on light follow-through.
Platform tools, order types and data feeds vary by provider. Some brokers or venues also have specific rules around very short holding periods or high message rates, so the exact experience can differ.
Costs, slippage and the reality of tiny edges
Because targets are small, costs can make or break the strategy. The spread is the first hurdle. You either need to capture moves that are larger than the spread or use resting orders to earn the spread. On top of that come commissions, exchange or venue fees, and in some markets maker or taker charges. Even small charges, repeated hundreds of times, add up.
Slippage is the other threat. In fast moves your order may fill worse than expected. If your plan counted on 3 ticks and you give up 1 or 2 in slippage, the edge shrinks or vanishes. Queue position matters: a limit order at the best price might sit behind others and never fill if the market moves away.
Finally, one large loss can undo many small wins. A stop that fails to trigger during a gap, or a moment of hesitation, can wipe out a session. This is why scalpers are strict about predefining exits and keeping size appropriate for the tiny targets they chase.
Risk control for scalpers
Good process beats impulse. Many scalpers cap their per-trade risk in cash terms, fix a daily loss limit, and stop trading when they are tired or the market conditions change. They use hard stops, avoid adding to losers, and reduce size when volatility expands. That is basic risk management, but applied at high speed.
Position sizing leans small compared with account size, especially when leverage is available. Leverage magnifies both returns and mistakes. Because holding periods are brief, overnight risk is usually avoided and financing costs matter less than execution costs. If you use platforms that charge for carrying positions, check how overnight and weekend rules apply in case a trade runs longer than expected. Policies vary by provider and can change.
Keep a log. Screenshots, entry reasons, exit reasons and notes on market context help you learn which setups actually pay after costs.
Scalping, day trading and other short-term styles
Scalping sits inside day trading but is more granular. A day trader might hold a position for thirty minutes to several hours, riding a trend or a pattern. A scalper works inside those moves, in and out many times, often flat by the time a day trader is still holding the first entry.
It is also different from market making. A market maker continuously posts both bids and offers and earns the spread for providing liquidity. A discretionary scalper may place or take liquidity opportunistically rather than quoting all the time. In options, you may hear about volatility scalping, which is a separate technique that tries to harvest differences between realised and implied volatility using a delta-hedged position. The common thread is small edges repeated often, but the mechanics differ.
Whatever the flavour, scalping relies on quick decisions, clean execution and discipline. The concept is simple: lots of small trades, small targets, tight control of losses. The practice takes testing and patience to see whether those tiny edges survive real costs and live conditions.
