NRML (Normal) and MIS (Margin Intraday Square-off) are two order types used by traders in the Indian stock market. NRML is strictly used for carrying forward positions in Futures & Options (F&O) and Commodities segments, whereas MIS applies broadly across Equities (Intraday Cash), F&O, and Commodities. The key difference lies in how long the position can be held and how the trade is settled.
While NRML is a trading type in which traders can stretch their positions overnight or till the contract/session expires, MIS is trading in which traders are required to settle the trade within the same trading day or before the session ends.
This article differentiates between NRML and MIS trading, including their advantages and disadvantages.
Key Takeaways
- NRML lets traders carry F&O positions overnight or until expiry, while MIS is strictly limited to intraday sessions.
- NRML requires full exchange margins, whereas MIS offers higher intraday leverage subject to regulatory norms.
- MIS positions carry an automated square-off risk if left unclosed near market closing time.
- Your choice depends entirely on your trading horizon, technical strategy, and capital allocation.
- F&O trading under both product types attracts business income tax classification under Indian tax laws.
What is NRML Trading?
Normal (NRML) is the product type used when traders take positions in the futures and options (F&O) segments that they intend to carry forward beyond the current trading session.
Traders can hold these positions overnight, across multiple days, or until the contract expires on expiry day.
- Primary Use: Positional and multi-day derivatives trading.
- Margin Requirements: Traders must maintain the full SPAN and Exposure margins mandated by the exchange and clearing corporation.
- Risk Exposure: Subject to overnight price gaps and global market volatility between sessions.
What is MIS Trading?
Margin Intraday Square-off (MIS) is designed specifically for intraday trading. Positions opened under MIS must be entered and exited within the same trading session.
If a trader fails to close the position before market close, the broker's risk management system will automatically square off the trade. Please note that automated square-offs executed by the broker’s Risk Management System (RMS) often carry additional penalties, operational charges, or call-and-trade charges.
- Primary Use: Single-day or short-term intraday trading.
- Leverage: Brokers often provide higher leverage or reduced margin requirements for intraday trades, subject to SEBI peak margin norms.
- Risk Exposure: Price fluctuations throughout the active trading session without overnight risk, though subject to automated square-off execution risks and associated service charges.
NRML vs MIS: Key Comparison
| Feature | NRML (Normal) | MIS (Margin Intraday Square-off) |
| Primary Objective | Positional or overnight F&O trading | Intraday trading |
| Holding Period | Multi-day, up to contract expiry | Same day only (closed before market close) |
| Margin & Leverage | Standard exchange SPAN and exposure margins | Higher intraday leverage (broker and SEBI dependent) |
| Overnight Risk | High exposure to overnight price gaps and global cues | None (all positions squared off intraday) |
| Square-off Mechanism | Manual exit by trader or upon contract expiry | Manual exit or automated broker square-off |
Advantages of NRML
-
Overnight positions: The NRML trades can be held overnight, carried forward for a few weeks or held until they expire.
-
Management flexibility: Holding trades beyond a day allows enough time for necessary developments across sessions.
-
F&O strategy: This suits multi-day F&O trading strategies, where permitted.
Disadvantages of NRML
-
Overnight risk: If you leave trades overnight, price fluctuations can be high, resulting in significant price gaps.
-
Frozen capital: Holding your trade for a few days means keeping your capital tied up for a long time.
-
Margin requirements: Traders must maintain a minimum margin of capital while holding an open derivatives trade.
Advantages of MIS
-
Suitable for short-term traders: MIS trading suits traders who prefer to trade for a short period or within a single day.
-
Intraday strategy: This is appropriate for trades that are expected to make significant price movements within a single day due to sudden events.
-
No overnight exposure: Since trades are closed the same day, they are not exposed to overnight price movements.
Disadvantages of MIS
-
Automated square-off: Trades must be closed on the same day at the end of the session. If the traders fail to do so, the broker automatically squares it off.
-
Limited holding period: Since it is intraday trading, positions cannot be carried forward to future days.
-
Broker limitation: The permit for MIS trading facility and intraday margin requirement depend on the instrument and the broker.
NRML vs MIS: Which One is Better
The choice depends on the trader’s requirements and strategy. It depends on the trading goal and what the trader wants to achieve.
NRML suits traders who prefer to hold a trade overnight or keep their F&O position for a few days, or until it expires. They look for gains from overnight price movements and can maintain the capital margin.
MIS suits traders who prefer to trade within a single day. They prefer not to carry forward their trade and focus on squaring off the trade before the session ends. They understand the risks of leverage and prefer to keep it low.
Regulatory Guideline, Tax Treatment for NRML vs MIS
Position Conversion
Most brokers permit traders to convert an MIS position to NRML during market hours. Please note that converting an MIS position to NRML requires adequate margin available in the trading account to cover the overnight requirements and must be executed before the market cut-off window (typically 15 to 20 minutes prior to market close). NRML positions, on the other hand, can often be converted to MIS if intraday criteria are met.
Tax Treatment
Under the Indian Income Tax Act, profits and losses from F&O trading (whether executed via MIS or NRML) are classified as business income (non-speculative business income under Section 43(5)), requiring proper bookkeeping and potential tax audits depending on turnover thresholds.
Conclusion
NRML and MIS serve different trading strategies. NRML suits overnight or carry-forward trades, while MIS suits single-day trades. Neither is a better product, since each has different features and serves traders with different objectives, holding periods, and requirements. NRML suits traders and investors who want to hold positions beyond the trading day. It is commonly used for carry-forward positions in eligible segments, allowing traders to remain invested overnight and potentially benefit from price movements over several days or longer. Since the position doesn't have to be closed the same day, NRML can be more appropriate for positional or overnight trading strategies.
