Scalping: Short-Horizon Trading, Execution, and Risk
Summary
Scalping seeks to accumulate small gains from brief price movements through frequent intraday trades. Positions may last seconds or minutes, and the approach relies on quick entries and exits, often using small time-frame charts, momentum indicators, support and resistance references, and order-book or time-and-sales information. The document illustrates the arithmetic with a hypothetical stock trade that targets small price increments on a large share quantity; it does not provide performance data.
The method depends heavily on execution quality, liquidity, and discipline. Frequent trading can raise commissions, while leverage and large positions can magnify losses as well as gains. Common failure modes include skipping stops, entering or exiting late, overtrading, and using too much leverage. The source describes specific US account and margin rules, but those details are time- and jurisdiction-sensitive and should not be treated as current guidance. Scalping is presented as a demanding, high-risk style rather than a universally suitable strategy.
Key ideas
- Scalping targets small price changes through frequent, short-duration intraday trades.
- Execution speed, liquidity, and careful order handling matter because the expected price move is small.
- Short-term charts and technical indicators may help scalpers assess momentum and reference levels.
- High turnover can increase commissions, while leverage and large positions amplify potential losses.
- A strict exit process and disciplined adaptation to changing conditions are central to the approach.
