How to Place a Stock Order in India: Market, Limit, Stop-Loss & More

The order book: where orders meet

Before understanding order types, it helps to understand where orders go. When you place an order through your broker, it is routed to the exchange (NSE or BSE), where it enters the order book— a real-time, centralised ledger of all pending orders for that stock.

The order book has two sides: the bid side (orders from people wanting to purchase) and the ask side(orders from people wanting to sell). The highest bid price and the lowest ask price are called the best bid and best ask (or best offer), respectively. The difference between them is the bid-ask spread.

For a large cap stock like Reliance Industries or TCS, the bid-ask spread during market hours was typically 5-10 paise — virtually negligible. For a small cap stock with low trading volume, the spread could be Rs 1-5 or more, meaning the cost of immediately transacting (the effective "entry toll") was significantly higher. This spread was an important but often overlooked transaction cost, especially for frequent traders.

Market order

A market order is the simplest order type: it instructs the broker to transact at the best available price in the order book immediately. When you place a market order to purchase, it matches with the lowest available ask price. When you place a market order to sell, it matches with the highest available bid price.

Example: suppose you want to purchase 100 shares of Infosys. The order book shows the best ask at Rs 1,502.30 for 200 shares. Your market order to purchase 100 shares executes immediately at Rs 1,502.30 (assuming no change between the time you see the price and the time your order reaches the exchange).

When to use it: market orders were ideal when speed mattered more than the exact price — for example, when exiting a position quickly during a sharp market move, or when the stock was highly liquid with a tight bid-ask spread (making the execution price predictable).

Risk: in illiquid stocks or during volatile moments, the execution price of a market order could differ significantly from the last traded price displayed on the screen. This phenomenon, called slippage, was the primary risk of market orders. In extreme cases — such as a stock with very few sellers at the best ask — a large market order could execute across multiple price levels, resulting in a much higher average purchase price than expected.

Limit order

A limit order specifies the maximum price you are willing to pay (for a purchase) or the minimum price you are willing to accept (for a sale). The order will only execute at your specified price or a more favourable price.

Example: Infosys is trading at Rs 1,502. You place a limit order to purchase 100 shares at Rs 1,495. Your order enters the bid side of the order book and sits there until either (a) a seller offers shares at Rs 1,495 or below, (b) you cancel the order, or (c) the trading session ends and the order expires (unexecuted limit orders typically cancel at the end of the day unless placed as GTT orders).

When to use it: limit orders provided price certainty at the cost of execution certainty. They were useful when you had a specific price in mind and were willing to wait — for example, when purchasing a stock at a small discount to the current market price.

Risk: the order might not execute if the stock price never reached your limit. Investors who set limit prices too far from the market price often watched the stock move away from them without executing the order.

Stop-loss (SL) order

A stop-loss order is a conditional order designed to limit potential losses on an existing position. It has two components: a trigger price and a limit price.

How it works:the order remains dormant in the system until the stock's price reaches the trigger price. Once triggered, it becomes a limit order at the specified limit price and enters the order book. The limit price is typically set slightly below the trigger price (for a sell SL order) to provide a buffer for execution.

Example:you hold 50 shares of HDFC Bank purchased at Rs 1,680. You want to exit if the price drops to Rs 1,640. You place a sell SL order with a trigger price of Rs 1,640 and a limit price of Rs 1,635. If HDFC Bank's price falls to Rs 1,640, the order triggers and becomes a limit sell order at Rs 1,635. It will execute at any price between Rs 1,640 and Rs 1,635 (or exactly at Rs 1,635 if the market is moving very fast).

Risk: in a fast-falling market (or a gap-down opening), the stock price might breach the trigger and blow past the limit price before the order can execute, leaving the stop-loss unexecuted. This was known as stop-loss slippage and was a real risk in volatile or illiquid stocks.

Stop-loss market (SL-M) order

An SL-M order works like a stop-loss order but without a limit price. Once the trigger price is hit, the order becomes a market order rather than a limit order. This guaranteed execution (assuming the stock was not frozen at a circuit limit) but did not guarantee a specific price.

When to use it: SL-M orders prioritised execution over price — useful when exiting a losing position quickly was more important than getting the exact desired exit price. They were preferred in highly liquid stocks where market order slippage was minimal.

Risk: in a gap-down scenario, an SL-M sell order could execute at a significantly lower price than the trigger. For example, if you set a trigger at Rs 500 and the stock opened the next day at Rs 470 (gap-down), the SL-M order would trigger and sell at approximately Rs 470 — a 6% worse price than your intended exit.

After Market Order (AMO)

Indian equity markets operate from 9:15 AM to 3:30 PM on weekdays. After Market Orders (AMOs) allow investors to place orders outside these hours — typically between 3:45 PM and 8:55 AM the next trading day, though exact timings vary by broker.

AMO orders are queued by the broker and sent to the exchange at the start of the next trading session. They can be market orders or limit orders. AMOs were particularly useful for salaried professionals who could not actively monitor or trade during market hours.

Important consideration:an AMO placed in the evening was based on the previous day's closing price, but the stock could gap up or down at the next day's opening. A limit AMO might not execute if the opening price was above your limit, and a market AMO might execute at a significantly different price than you expected.

Bracket order

A bracket ordercombined three orders into one: an initial entry order (market or limit), a profit-taking order (limit sell at a higher price), and a stop-loss order (sell at a lower price). The three orders "bracketed" the position — one side captured profits if the stock moved favourably, and the other side limited losses if it moved adversely. When one side executed, the other was automatically cancelled.

Example: you purchased 100 shares of TCS at Rs 3,800 via a bracket order with a profit target of Rs 3,860 and a stop-loss at Rs 3,770. If TCS rose to Rs 3,860, the profit-target order executed and the stop-loss was cancelled. If TCS fell to Rs 3,770, the stop-loss executed and the profit-target was cancelled. The investor defined both the maximum loss and the profit exit point upfront.

Bracket orders were available primarily for intraday trading (MIS product type) and were not universally available for delivery trades. Not all brokers offered bracket orders, and some had discontinued them citing complexity and risk management challenges.

Cover order

A cover orderwas a simpler version of the bracket order: it combined an entry order with a compulsory stop-loss order but did not include a profit-target order. The mandatory stop-loss reduced the broker's risk, which sometimes allowed brokers to offer additional leverage on cover orders.

Like bracket orders, cover orders were primarily available for intraday trades. Several brokers phased out cover orders or merged their functionality with bracket orders, so availability varied.

GTT and GTC orders

Good Till Triggered (GTT) orders were long-standing conditional orders that remained active for an extended period (typically up to one year, depending on the broker). Unlike a regular limit order that expired at the end of the day, a GTT order persisted until the trigger price was reached or the order expired.

Example: you wanted to purchase ITC at Rs 410 but it was currently trading at Rs 445. You placed a GTT order with a trigger at Rs 412 and a limit price of Rs 410. The order would sit dormant for weeks or months until ITC reached Rs 412, at which point it would activate as a limit order at Rs 410. This was useful for investors who had a price target in mind but did not want to monitor the stock daily.

GTT orders also served as long-standing stop-losses for delivery holdings. An investor holding 200 shares of Bajaj Finance purchased at Rs 7,000 could place a GTT sell order with a trigger at Rs 6,200 and a limit at Rs 6,150. This stop-loss would remain active for up to a year, providing downside protection without the investor needing to place a fresh stop-loss order each day.

GTC (Good Till Cancelled) was a broader term used by some brokers for orders that remained active until explicitly cancelled by the investor. The functional difference between GTT and GTC was primarily in the duration and the trigger mechanism — GTT orders typically had a price trigger, while GTC orders might simply remain as pending limit orders.

T+1 settlement in India

India transitioned to T+1 settlement for all stocks on NSE and BSE by January 2023. This meant that when you purchased shares on day T (the trade day), the shares were credited to your demat account and the funds were debited from your trading account on day T+1 (the next business day).

The previous settlement cycle was T+2 (two business days after the trade). India's move to T+1 made it one of the fastest settlement markets globally — most developed markets still operated on T+2 at the time of the transition.

What T+1 meant for orders:

• If you placed a purchase order on Monday and it executed, the shares appeared in your demat account on Tuesday.
• If you placed a sell order on Monday and it executed, the sale proceeds were available in your trading account on Tuesday.
• BTST (purchasing today and selling tomorrow) remained possible because the shares were credited the next day. Read more about BTST in our intraday vs delivery guide.

Circuit limits: upper and lower

Indian exchanges imposed circuit limits— price bands that restricted how much a stock's price could move in a single trading session. The purpose was to prevent extreme price manipulation and limit panic-driven moves.

Most stocks had circuit limits of 2%, 5%, 10%, or 20%above and below the previous day's closing price. The applicable band depended on the stock's volatility category, which the exchange determined based on historical price behaviour.

• Upper circuit (UC): when a stock rose to its upper circuit limit, trading effectively paused on the ask side — there were no sellers willing to sell at the circuit price, and the price could not go higher. Orders to purchase remained in the book but could not execute until the next day (when the circuit band reset).
• Lower circuit (LC): the mirror situation — the stock fell to its lower circuit, and there were no willing purchasers. Sellers who wanted to exit were trapped because there was no demand at the circuit price.

Stocks in the Futures and Options (F&O) segmentdid not have fixed circuit limits. Instead, they operated under dynamic price bands that widened automatically if the stock hit the band, with a brief cooling-off period. This prevented the freeze-at-circuit phenomenon that affected stocks outside the F&O segment. For more on F&O mechanics, see our F&O margin guide.

Pre-open and post-close sessions

Indian exchanges operated two special sessions outside the continuous trading window:

Pre-open session (9:00 AM to 9:15 AM): this session determined the opening price through a call auction mechanism. During the first 8 minutes (9:00-9:08), orders could be placed, modified, or cancelled. From 9:08-9:12, only order matching occurred (no new orders or modifications). The exchange then calculated the equilibrium price — the price at which the maximum number of shares could be traded — and this became the opening price. Unmatched orders were carried forward to the continuous trading session.

Post-close session (3:40 PM to 4:00 PM): after the continuous trading session ended at 3:30 PM, the exchange calculated the closing price (a volume-weighted average of the last 30 minutes of trading). The post-close session then allowed orders to be placed at this closing price only. This session was used primarily by institutional investors for executing orders at the official closing price.

Common order mistakes beginners make

• Using market orders in illiquid stocks: placing a market order for a stock with a wide bid-ask spread could result in execution at a significantly worse price than expected. A limit order was almost always preferable for illiquid stocks.
• Setting stop-loss too close to the current price:a stop-loss placed 1-2% below the purchase price in a volatile stock would frequently get triggered by normal intraday fluctuations, causing an unnecessary exit. Understanding a stock's typical daily range was important for setting meaningful stop-loss levels.
• Forgetting to cancel open orders:a limit order placed in the morning that did not execute could sit in the order book all day. If the stock's fundamentals or market conditions changed during the day, the stale order might execute at an inopportune time.
• Confusing order product types: placing an order under MIS (intraday) when intending to take delivery, or vice versa. MIS orders were auto-squared off before market close, which could force an exit at an unfavourable price. Always verify the product type before confirming an order.
• Not accounting for brokerage and charges: an order that appeared profitable at the execution price might turn into a loss after accounting for brokerage, STT, exchange transaction charges, GST, and stamp duty. Use our brokerage calculator to calculate the total cost of a trade before placing it.
