Scalping
A hyper-short-term trading style where traders capture many small price moves throughout the session, each held for seconds to a few minutes.
Definition
Scalping is an intraday trading style in which a trader enters and exits positions rapidly — typically within seconds to a few minutes — aiming to capture very small price increments repeatedly across many trades in a single session. Rather than relying on large moves, scalpers depend on the law of large numbers: a high volume of small wins that collectively exceed the sum of small losses and transaction costs. It is the most time-intensive trading style and demands near-constant screen time, fast execution, and iron discipline on stop-loss orders. All positions are squared off before the close, making it a strict subset of intraday trading.
Why it matters
Scalping is particularly popular among retail traders in Nifty 50 and Bank Nifty futures and options on NSE, where tight bid-ask spreads and high liquidity enable rapid entries and exits. A scalper in Bank Nifty futures might target moves of just Rs 20–50 per lot, but with multiple lots and dozens of trades in a session, the aggregate P&L becomes meaningful. The strategy's edge lies in exploiting short-term inefficiencies — order book imbalances, post-news ticks, or momentum bursts — before the market re-equilibrates.
The risks of scalping are equally concentrated. Slippage on market orders, brokerage per trade, Securities Transaction Tax (STT), and the psychological toll of managing many simultaneous positions can quickly erode thin margins. Successful scalpers on NSE typically use limit orders wherever possible, trade only the most liquid strike prices, and maintain a strict maximum daily loss limit beyond which they stop trading entirely for the day.
How it works
A scalper identifies a high-probability short-term bias using a combination of 1-minute or 3-minute candlestick charts, order flow data, and indicators such as VWAP or Level 2 order book depth. Once a setup triggers — say, a price approaching VWAP support with a buyer stepping in at the bid — the scalper enters with a tight stop (often just a few ticks below entry) and a target of 2–3 times the stop distance. The moment either level is hit, the position is closed and the scalper moves on to the next setup. Risk per trade is kept very small relative to account size, because the frequency of trades means even a modest run of losses must not threaten the account.
Example
Suppose a trader is scalping Nifty 50 futures during the first hour of trading. The contract is oscillating around its VWAP at 23,750. The trader notices that every time price dips to 23,740 the order book shows a large buyer, and the contract snaps back to 23,760 within a minute. They enter long at 23,742 with a stop at 23,732 (10 points risk) and a target of 23,762 (20 points reward). The trade takes 90 seconds and closes at the target. Across 20 similar setups in the session, even a 55% win rate with a 2:1 reward-to-risk ratio generates a positive expected outcome before costs.
