What Is Intraday Trading and How Does It Work on NSE

What does intraday trading mean in practical terms?

Intraday trading refers to the buying and selling of shares or other securities within the same trading day on the National Stock Exchange of India. All positions are opened and closed during a single session, and no shares are delivered to the trader's demat account. The goal is to capture short-term price movements—sometimes over minutes or hours—rather than to invest for long-term growth.

Unlike delivery-based trading where an investor holds shares for weeks, months or years, intraday traders focus on immediate technical setups, news catalysts and market momentum. Profits (or losses) are realized on the same day, and the next morning the slate is clean.

How does the NSE trading day structure affect intraday traders?

Understanding NSE market timings is fundamental for anyone attempting intraday trading. The official schedule is:

Most intraday activity happens between 9:15 AM and 3:30 PM. The first 15 to 30 minutes often exhibit high volatility due to overnight news, gap openings and large institutional orders. Many experienced traders wait until 9:30 or 9:45 AM before placing their first trade, allowing initial volatility to settle and clearer trends to emerge.

Brokers typically begin auto square-off of open MIS positions between 3:15 PM and 3:25 PM. The exact cut-off time varies by broker and is stated in the risk-disclosure document. Traders who forget to manually exit will have their positions closed at prevailing market prices, and a small square-off fee may apply.

What is an MIS order and how does margin work?

When placing an order through a broker's platform, traders select a product type. For intraday positions, the correct choice is MIS (Margin Intraday Square-off). Selecting CNC (Cash and Carry) or NRML (Normal) would imply delivery or carry-forward, which is not the intent in intraday trading.

An MIS order signals two things to the broker: the position will be closed within the day, and intraday margin applies. Under SEBI's peak-margin framework introduced in September 2020 and enforced in phases through 2021, brokers must collect a minimum margin for intraday equity trades. Currently, this translates to roughly 20% of the position value, offering leverage of up to about 5x.

For example, a trader with ₹20,000 in the trading account could take an intraday position worth approximately ₹1,00,000 in a liquid stock such as HDFC Bank or Reliance Industries. While this amplifies potential gains, it also magnifies losses. A 1% adverse move on a ₹1,00,000 position results in a ₹1,000 loss—5% of the trader's capital wiped out in a single trade.

Brokers monitor margin in real time. If the position moves significantly against the trader and margin falls below the required level, the broker may issue a margin call or square off the position automatically to limit risk.

Can traders short sell in intraday trading?

Yes. One of the key advantages of intraday trading in the cash segment is the ability to short sell—that is, to sell shares first and buy them back later at a lower price. In the Indian equity cash market, short positions cannot be carried overnight; they must be covered before the trading session ends.

For instance, if a trader anticipates a decline in Infosys after weak global technology earnings, shares can be sold at ₹1,500 and bought back at ₹1,485, booking a ₹15 per share profit (before costs). This flexibility allows traders to profit in both rising and falling markets, provided they correctly anticipate direction.

It is important to note that while shorting is straightforward intraday, attempting to short without covering before 3:30 PM will result in an automatic buy-back by the broker at the prevailing market price, potentially at an unfavorable level.

Worked example using NSE daily closes for Reliance Industries

Consider the following sequence of NSE daily closing prices and volumes for Reliance Industries over October 2026:

• 2026-10-14: Open ₹1,167.00, High ₹1,188.00, Low ₹1,162.70, Close ₹1,174.60, Volume 10,938,195
• 2026-10-15: Open ₹1,185.20, High ₹1,218.80, Low ₹1,177.20, Close ₹1,215.00, Volume 23,456,219
• 2026-10-16: Open ₹1,215.00, High ₹1,215.40, Low ₹1,193.00, Close ₹1,211.20, Volume 17,225,283
• 2026-10-19: Open ₹1,212.00, High ₹1,228.20, Low ₹1,201.00, Close ₹1,202.00, Volume 15,572,554
• 2026-10-21: Open ₹1,212.00, High ₹1,234.30, Low ₹1,199.30, Close ₹1,209.00, Volume 17,607,823
• 2026-10-22: Open ₹1,206.20, High ₹1,208.00, Low ₹1,184.50, Close ₹1,184.50, Volume 14,957,042
• 2026-10-23: Open ₹1,184.00, High ₹1,201.90, Low ₹1,163.10, Close ₹1,190.00, Volume 14,905,641
• 2026-10-26: Open ₹1,186.10, High ₹1,204.50, Low ₹1,174.50, Close ₹1,201.80, Volume 7,490,515
• 2026-10-27: Open ₹1,195.00, High ₹1,202.60, Low ₹1,184.00, Close ₹1,196.20, Volume 13,067,787
• 2026-10-28: Open ₹1,194.50, High ₹1,204.30, Low ₹1,156.40, Close ₹1,158.00, Volume 21,866,598
• 2026-10-29: Open ₹1,159.00, High ₹1,182.10, Low ₹1,155.60, Close ₹1,167.40, Volume 20,939,623
• 2026-10-30: Open ₹1,170.40, High ₹1,174.60, Low ₹1,152.50, Close ₹1,164.90, Volume 14,753,150

On October 15, Reliance opened at ₹1,185.20 and rallied to a high of ₹1,218.80 on heavy volume (23,456,219 shares), closing near the top at ₹1,215.00. An intraday trader monitoring the stock might have noticed the gap-up open and strong momentum in the first hour. Suppose the trader entered a long MIS position at ₹1,195.00 after the stock held above the opening price and showed buying interest.

With a ₹20,000 account and 5x leverage, the trader could afford roughly ₹1,00,000 exposure, equating to about 83 shares at ₹1,195.00. A disciplined trader would set a stop loss—say at ₹1,186.00 (risking ₹9 per share or ₹747 total, roughly 3.7% of capital)—and a target at ₹1,213.00 (a ₹18 gain per share or ₹1,494 potential profit).

If the stock moved to ₹1,213.00 by mid-afternoon, the trader would exit, booking approximately ₹1,494 before costs. If instead the stock reversed and hit ₹1,186.00, the stop loss would trigger, limiting the loss to ₹747. In reality, the stock closed at ₹1,215.00, meaning the target would have been achieved.

Contrast this with October 22, when Reliance opened at ₹1,206.20 and fell steadily to close at ₹1,184.50, a decline of ₹21.70. A trader who went long at the open without a stop loss or who averaged down would have faced a significant loss. An intraday short seller, however, might have sold at ₹1,203.00 in the morning and covered at ₹1,188.00 in the afternoon, profiting from the downtrend.

These examples illustrate the importance of direction, timing, stop losses and the discipline to exit—whether at a profit or a small controlled loss.

What are the transaction costs in intraday trading?

Intraday trading involves multiple charges on every trade, and these costs compound rapidly with frequent activity. The components include:

• Brokerage: charged by the broker per trade or as a percentage. Discount brokers typically charge ₹10–₹20 per executed order; full-service brokers may charge 0.03–0.05% of turnover.
• Securities Transaction Tax (STT): levied by the government at 0.025% on the sell side of equity delivery trades. For intraday equity, STT is 0.025% on the sell side only.
• Exchange transaction charges: NSE charges approximately 0.00325% of turnover.
• SEBI turnover fee: 0.0001% of turnover (₹10 per crore).
• Stamp duty: state governments levy stamp duty at 0.003% on the buy side (₹3 per ₹1,000).
• GST: 18% on brokerage and transaction charges.

For a round-trip intraday trade of ₹1,00,000 (₹50,000 buy, ₹50,000 sell), total charges can range from ₹50 to ₹150 depending on the broker. If a trader executes ten round trips in a day, costs could easily exceed ₹500 to ₹1,500. Over a month, that becomes ₹10,000 to ₹30,000—a significant drag on profitability.

Many beginners focus on gross P&L shown in the trading platform and are surprised when the contract note reveals net P&L after all charges. Always check the net P&L to understand true performance.

What rules and practices help traders survive intraday trading?

Successful intraday trading requires strict discipline, because the speed and leverage involved can lead to rapid capital erosion. Several core principles apply:

A common rule is to risk no more than 1% of trading capital per trade. For a ₹50,000 account, that means a maximum loss of ₹500 on any single position. This is enforced by setting a stop loss based on technical levels or volatility. If the distance from entry to stop loss is ₹10 per share, the trader would buy only 50 shares.

Additionally, set a daily loss limit—often 2–3% of capital. If losses reach ₹1,000 to ₹1,500 on a ₹50,000 account, stop trading for the day. Continuing to trade after hitting this limit often leads to revenge trading and deeper losses.

Liquidity is critical in intraday trading. Illiquid stocks have wide bid-ask spreads, low volume and slippage—meaning orders may not fill at intended prices. Stick to constituents of NIFTY 50, NIFTY 100 or the top tier of NIFTY 500. Stocks such as Reliance Industries, HDFC Bank, Infosys, ICICI Bank and TCS offer tight spreads and ample volume throughout the day.

Every trade should have three elements defined in advance: entry reason (a specific technical setup, breakout, support/resistance level), stop loss (an invalidation point where the trade idea is wrong), and target (a realistic profit level based on recent volatility or chart structure).

Clicking buy or sell on impulse, based on a hunch or a tip, is speculation without structure. Structured trades can be reviewed and improved; random trades cannot.

Averaging down—buying more shares as the price falls—is a common mistake. In intraday trading with leverage, this can turn a small loss into a large one very quickly. If the original trade idea is invalidated by price action, exit at the stop loss. Do not add to a losing position hoping for a reversal.

A simple spreadsheet with columns for date, stock, entry price, exit price, stop loss, target, reason for entry, result (win/loss/breakeven), and notes on what went right or wrong is invaluable. Reviewing this journal weekly helps identify patterns—both good setups that work repeatedly and recurring mistakes to avoid.

Common mistakes that hurt intraday traders

Many traders repeat the same errors, often because they focus on winning trades and ignore the process. Recognizing these mistakes early can save significant capital:

Overtrading: Taking ten or fifteen trades a day, chasing every small move, leads to decision fatigue and racks up transaction costs. Quality over quantity applies in trading; two or three well-planned trades often outperform a dozen random entries.

Ignoring stop losses: Hoping a losing trade will come back is not a strategy. The market does not care about a trader's entry price. Stop losses exist to preserve capital for the next trade.

Trading the first five minutes: The opening minutes are often chaotic, with wide spreads, gaps and emotional reactions to overnight news. Waiting fifteen to thirty minutes allows clearer trends and better entry prices.

Chasing breakouts without confirmation: Buying a stock just because it crossed a resistance level, without checking volume, momentum or broader market context, often results in getting trapped in a false breakout.

Using maximum leverage on every trade: Just because 5x leverage is available does not mean it should always be used. Smaller position sizes leave room for error and reduce the psychological pressure that leads to poor decisions.

Failing to adapt to market conditions: Strategies that work in a trending market may fail in choppy or range-bound conditions. Recognizing when to step aside is as important as knowing when to trade.

Is intraday trading suitable for most retail traders?

The evidence suggests that intraday trading is challenging for the majority of retail participants. SEBI analysis of trading data has consistently shown that a large percentage of individual intraday traders incur net losses over six-month and twelve-month periods. High transaction costs, leverage, emotional decision-making and lack of a tested process all contribute to this outcome.

That does not mean profitable intraday trading is impossible. Traders who approach it as a skill to be developed—who start with small size, keep detailed records, follow strict risk rules, and continuously refine their methods—can improve their odds. The first few months should be treated as an apprenticeship, where the goal is to learn and avoid large losses, not to generate income.

For most people, a combination of delivery investing for long-term growth and occasional swing trades (holding for a few days) offers a more realistic path than full-time intraday trading. Those who do pursue intraday trading should ensure they have separate capital set aside—capital they can afford to lose—and should never trade with borrowed money or funds needed for living expenses.

Final thoughts on building an intraday trading process

Intraday trading on NSE is accessible, with low account minimums, user-friendly platforms and ample educational resources. The barrier to entry is low, but the barrier to consistent profitability is high. Success depends less on predicting every move and more on managing risk, controlling emotions and executing a repeatable process.

Traders who survive and eventually thrive are those who respect the difficulty, commit to continuous learning, and accept that losses are part of the business. Every trade is a data point; every mistake is a lesson. The goal is not to win every trade but to ensure that winning trades are larger than losing trades and that risk is always capped.

Understanding how MIS orders work, respecting NSE timings, calculating all costs, setting strict stop losses and maintaining a journal are not optional extras—they are the foundation. Build that foundation first, and the trading results will follow over time.
