Scalping is an intraday approach that targets very small price moves over seconds or minutes using many trades and tight controls. Positions are opened and closed repeatedly, usually when liquidity is strongest.
Is it too risky for most traders? Often yes. Once spread, slippage, and fees are counted, the margin for error is thin, and small execution slips can turn a workable plan into losses.
Results depend as much on friction and fills as on setups. Spreads, order routing, queue position, and platform speed can shape outcomes more than indicator choice.
Scalping also teaches risk control. Predefined loss limits, quick exits, and a refusal to chase can improve performance across other trading styles.
Trading is cheapest and cleaner when participation is high. Focus on liquid instruments and sessions where spreads are tight and depth is steady. For currencies, the London and New York overlap often has the best liquidity and follow-through. Use order types that balance speed with price control and avoid thin patches or major news unless the playbook is designed for them.
Trade during high participation windows to reduce spreads and slippage.
Use marketable limit orders for speed or passive limits when the queue position is strong.
Stand aside during thin liquidity or events that cause unpredictable gaps.
Use one short-term chart for triggers and a slightly higher timeframe for context. Keep the rules set small and repeatable.
Levels: opening range, prior high or low, and marked intraday support or resistance.
Confirmation: a brief volume surge or a simple momentum thrust that aligns with the level.
Exits: take partial profit at the first reaction point and trail under the latest swing.
With a $5,000 account risking 0.5%, which is $25 per trade, buy 200 shares at $20.00 with a stop at $19.95 and a target at $20.06. The gross potential is $12, and the gross risk is $10. A 1-cent spread and 1-cent total slippage can remove $4 to $6 of the $12 before fees. Expect slippage to worsen around scheduled announcements. Reduce size or pause during release windows. Only take this kind of setup when spreads are tight, depth is firm, and every item on the checklist is met.
Costs decide outcomes as much as entries. Small targets demand clean execution and careful venue selection.
Spread and slippage can consume a large share of a 6 to 10 cent target each round turn.
Commissions and fees change, break even and position sizing.
Routing and rebates can add or reduce net cost, so measure and adapt.
Spreads usually widen in thin or highly volatile instruments. This raises round-trip costs and the break-even threshold.
| Mistake | Impact | Fix |
|---|---|---|
| Chasing more trades for more profit | Fees and errors rise while the edge falls | Cap daily trades and favour quality over count |
| Ultra-tight stops inside noise | Frequent stop-outs and frustration | Place stops beyond typical noise and size down |
| Trading thin or newsy periods | Gaps and slippage overwhelm small targets | Stick to liquid windows or reduce the size or stand aside |
| Relying on indicators for timing | Late or noisy entries | Use indicators for context and execute on price, level, and volume |
Day Trading: intraday trading with longer holds and fewer tickets than scalping.
Spread: the gap between bid and ask that forms a core cost in fast strategies.
Slippage: the difference between expected and actual fill price.
Depth of Book, Level 2: visible queued orders that hint at near-term liquidity.
Professionals design for microstructure first. They trade at liquid times, choose instruments for depth, and use repeatable entry locations such as opening range levels or prior extremes. They also set a daily loss limit, a maximum trades count, a pause after two consecutive losses, and a stop for the day rule. If trading United States equities on margin, confirm pattern day trader status and equity requirements before adopting a high-frequency plan. They log realised slippage against plan and remove setups that cannot overcome friction.
Scalping can work, but the tolerance for risk and the execution burden are high. For most traders, the edge is too thin after costs, slippage, and human error.
A better path is to learn the discipline scalping demands, then apply those habits to a slower style, or approach scalping only with a tested plan, robust tools, and strict personal limits.
