Open any list of trading styles and scalping sits at the fastest end. Traders enter and exit within minutes, sometimes seconds, and repeat that dozens of times in a single session.
The appeal is easy to see. There is generally no overnight market exposure. There is no waiting for weeks while a trade plays out. The outcome of each position is realized within the same trading session.
But scalping is also the most demanding style to run. It needs full attention through market hours, quick execution, and an understanding of costs that other trading styles can afford to ignore.
This is Part 1 of our complete guide. Let’s break down what scalping is, its pros and cons, how it differs from day trading and swing trading, costs involved, and risk management.
Scalping is a trading style where a trader aims to profit from very small price movements, repeated many times in a single session. Positions are typically opened and closed within minutes, sometimes seconds.
The logic behind it is simple. Small price changes occur far more frequently than large price moves, giving scalpers opportunities to target small movements rather than waiting for a larger move.
Two things define the style: small price movements and frequent repetition.
Because each individual price movement is small, position size matters. A move of less than 1% may produce a relatively small gain or loss on a small position, but the same move can translate into a meaningful rupee amount on a larger position. The reverse is equally true: a small move against the position can quickly turn into a meaningful loss when position size is large.
Example:
A trader buys 2,000 shares at ₹500 each and sells at ₹502.
The move is ₹2 per share, or 0.4%.
The gross gain is ₹4,000.
If the same trade moves ₹2 the other way, the loss is also ₹4,000.
A scalper may take dozens of trades in a single session, depending on the strategy and market conditions.
Like any trading style, scalping has its strengths and its trade-offs.
| Factor | Pros | Cons |
|---|---|---|
| Time and exposure | Positions close the same day, so overnight news and gaps cannot hit the trade | Requires constant attention to the market through the session |
| Trade frequency | Small moves happen often, so opportunities come up many times a day | Brokerage and charges repeat on every trade and add up |
| Size of move | Small gains accumulate across many trades | A small move the wrong way can produce a significant loss, especially with a large position or leverage |
Two more points sit outside this table. Scalping is not dependent on market direction and can be applied in both rising and falling markets. It also needs sophisticated platforms and real-time data, along with the experience and discipline to make decisions at that speed.
One clarification first, because this is where most of the confusion sits. Scalping is technically a form of day trading. A scalper does not carry positions into the next trading day either. What separates them is how long a position is held and how many trades are taken.
| Factor | Scalping | Day Trading | Swing Trading |
|---|---|---|---|
| Holding period | Seconds to a few minutes | Minutes to hours, closed the same day | A few days to a few weeks |
| Trades in a day | Often dozens or more | Many but usually less than scalp trades | Fewer, even none on a given day |
| Overnight risk | None | None | Carries overnight and over weekends risk |
| Screen time | Constant attention through the session | Full day monitoring | A few hours a week |
One more difference sits outside the table. Scalpers typically trade more frequently than other day traders, often targeting smaller price movements on each position. Position size is what determines how much a small price movement translates into in absolute terms.
There is no separate rate card for scalping. Since positions open and close within the same session, every scalping trade is billed under standard intraday equity charges. What changes is how much of the profit those charges consume.
Here is what every scalping trade pays:
Brokerage : Discount brokers may charge ₹20 or 0.03% of turnover per executed order, whichever is lower. Full-service brokers may charge percentage-based brokerage. Brokerage generally applies to both buy and sell orders.
STT : This is applied only when a trader exits the trade. So 0.025% is on the sell side only. It applies whether the trade made money or lost it.
Exchange transaction charges : NSE currently charges 0.00307% and BSE charges 0.00375% on equity intraday turnover, applied to both the buy and sell sides.
SEBI turnover fees : 0.0001% of trade value, or ₹10 per crore.
Stamp duty : It is a government fee charged on the buy side and is 0.003% of transaction value or ₹300 per ₹1 crore.
GST : 18% is charged on brokerage and transaction charges combined.
For example, buying 500 shares at ₹500 and selling at ₹501 gives a gross gain of ₹500. After brokerage, taxes and other charges, the actual profit is lower. The exact break-even point depends on the broker, exchange and trade value.
In scalping, trades rarely go wrong in one dramatic moment. A stop loss going in late. Another position being slightly larger than planned. A trade is held a little longer than intended. On their own these look minor. Across a dozen trades in one session, they add up.
This is why risk in scalping is decided before the session starts, not during it.
Risk per trade : A fixed percentage of total capital, usually between 0.5% and 2%. On a capital of ₹1,00,000, a 1% limit puts the maximum loss on any single trade at ₹1,000. That number stays the same regardless of confidence, market conditions, or how the previous trade went.
Stop loss placement : The stop goes where the trade idea stops being valid, not where the loss starts feeling uncomfortable. In practice, that may mean placing a stop below a relevant support level for a long trade or above a relevant resistance level for a short trade.
Position size : This follows from the first two. Once risk per trade and stop loss distance are fixed, position size can be calculated rather than decided in the moment.
Maximum trades per session : A cap on trade count prevents overtrading on days when setups are not appearing clearly.
Trade journal : A record of entries, exits, setup type and execution quality. Across a few sessions it shows whether stop losses are actually being followed or quietly adjusted mid-trade.
Scalping can look like the easiest style to start with. The moves are small, the trades are over in minutes, and nothing carries into tomorrow.
That is also what makes it the hardest. When the target is a small price move, small things become decisive. The cost of the trade. The gap between the buying and selling price. A stop loss placed a few seconds late. There is no room for a trade to sit and recover on its own.
Notice that everything in Part 1 happens before a single order goes out. What scalping is, how it compares to other styles, what it costs, and what risk management looks like. That preparation is most of the work.
Part 2 covers the trade itself. We look at what makes a stock suitable for scalping, the setups scalpers commonly work with, a step by step walkthrough of how a trade is put together, and where Tradomate fits in.
