Intraday Trading Rules in India: What You Need to Know

Intraday Trading in India: The Rules

Intraday trading, also known as day trading, involves buying and selling stocks within the same trading session. In India, intraday trading is governed by specific rules set by SEBI, the exchanges (NSE and BSE), and individual brokers. Understanding these rules is essential before engaging in day trading to avoid penalties, unexpected losses, or regulatory issues.

Trading Hours

The regular trading session on NSE and BSE runs from 9:15 AM to 3:30 PM IST. Pre-market session is from 9:00 AM to 9:15 AM, where orders are collected and matched at a single equilibrium price. Post-market session (3:40 PM to 4:00 PM) allows limited order placement at closing price. All intraday positions must be squared off before the market closes or within the broker-specified cutoff time.

Margin Requirements

Intraday Margin

Brokers provide leverage for intraday trading through reduced margin requirements. While delivery trades require the full value of the purchase, intraday trades may require only a fraction. SEBI has been progressively tightening intraday margins. Currently, the minimum margin for intraday equity trading is based on VaR (Value at Risk) and ELM (Extreme Loss Margin) calculations.

Peak Margin Rules

SEBI''s peak margin rule requires brokers to collect upfront margins from traders. The exchange monitors intra-day peak positions, and brokers must ensure clients have sufficient margins at all times. This rule, fully implemented in recent years, has reduced the leverage available to intraday traders compared to earlier periods.

Square-Off Rules

All intraday positions must be squared off before the end of the trading day. Most brokers set an auto square-off time, typically between 3:15 PM and 3:25 PM. If you do not close your intraday position, the broker will automatically square it off near the cutoff time. Auto square-off charges may apply, which are additional to regular brokerage.

It is best practice to manage your own exits rather than relying on auto square-off. The auto square-off happens at the market price prevailing at that time, which may be unfavorable due to end-of-day volatility.

Product Types

Indian brokers offer different product types for intraday and delivery trades. MIS (Margin Intraday Square-off) is the standard intraday product that provides margin leverage and must be squared off the same day. CNC (Cash and Carry) is for delivery trades where you pay full value and can hold indefinitely. NRML is for overnight futures and options positions. Make sure you select the correct product type, as selecting CNC for a trade you intended as intraday means paying the full amount.

Circuit Limits and Trading Halts

Individual stocks have daily price circuit limits (typically 5%, 10%, or 20% depending on the stock''s volatility and exchange rules). Once a stock hits its upper or lower circuit, trading is halted or restricted. Index-level circuit breakers trigger market-wide trading halts at 10%, 15%, and 20% declines in the benchmark indices. These can significantly affect intraday trading strategies.

Securities Eligible for Intraday Trading

Not all stocks are suitable for intraday trading. Brokers typically allow intraday trading only in liquid stocks that are part of the major indices or meet minimum volume criteria. Stocks in the trade-to-trade (T2T) segment cannot be traded intraday and must be taken for delivery. Always check whether a stock is available for MIS trading before planning an intraday trade.

Tax Implications

Intraday trading profits are classified as speculative business income under Indian tax law. This is taxed at your applicable income tax slab rate, which can be as high as 30% plus surcharge and cess. Speculative losses can only be offset against speculative income, not against salary or other income. However, they can be carried forward for up to 4 years.

Securities Transaction Tax (STT) for intraday equity trades is levied at 0.025% on the sell side only. Plus there is brokerage, exchange transaction charges, GST, and stamp duty. These costs add up and must be factored into your profitability calculations.

Best Practices for Intraday Trading in India

Trade only liquid stocks with high volume and tight spreads. Always use stop-loss orders for every trade. Start with small position sizes and increase gradually. Have a defined trading plan before the market opens. Avoid overtrading, especially after a loss. Keep a trading journal to track and improve performance. And never convert a losing intraday position to delivery hoping for a recovery.

The opportunities include consistent daily volume, well-defined trading hours, and predictable patterns around market open and close. The challenges include execution speed requirements, margin management, and ensuring positions are squared off on time.
