An after market order (AMO) is a feature offered by many brokers that lets you place a buy or sell order outside normal equity market hours. For instance, if you analyse a stock in the evening and decide to invest, an AMO allows you to place the order immediately instead of waiting for the market to open the next day. For retail investors, this can feel especially convenient when you’re planning trades after work and want your order queued for the next session. This guide explains what an after-market order is, typical AMO timings, types of after-market orders, and what to keep in mind before placing one.
What is an after market order in the share market?
An AMO is a type of order you place when the exchange is closed for normal trading, allowing you to plan trades in advance instead of waiting for market hours. The broker stores the order and sends it to the exchange when the exchange starts accepting orders (often during the next session’s pre-open or market hours, depending on broker setup and exchange window), where it is executed based on price and market conditions.
AMO timings in the stock market
AMO windows vary by broker and segment (equity, derivatives, commodities). The broad idea remains the same: you place an order outside normal trading hours, and it is forwarded when the exchange order window opens.
Common AMO Timing Buckets
| Segment | AMO Timing Window | Notes |
| Equity (NSE) | Typically, 3:45 pm to 8:57/8:58 am | Orders are placed after market close and before pre-open |
| Equity (BSE) | Typically, 3:45 pm to 8:59 am | Slight variation in cut-off vs NSE |
| F&O | Typically, 3:45 pm to 9:10 am | Extended window due to derivatives segment timing |
| Currency | Typically, 3:45 pm to 8:59 am | Similar to equity but may vary slightly |
| Commodity (MCX) | AMOs can be placed almost anytime outside trading hours, depending on broker | Trading runs in two sessions, often extending late into the night |
- Late evening / overnight acceptance: Many platforms keep AMO placement available for extended hours.
- Next-day forwarding: Orders are typically pushed to the exchange at the start of the next trading day’s acceptance window.
- AMO windows are not fixed by exchanges and can vary across brokers and segments. Always check your broker’s exact cut-offs.
Here is an example to help you understand how an AMO works:
Suppose you want to buy 50 shares of a company at ₹1,200, but it is already 4:00 pm and the market has closed for the day. You place a limit AMO through your broker, and the order is stored overnight until the exchange starts accepting orders the next day.
If your specified price matches during the pre-open session (typically between 9:00 am and 9:07 am), your order may get executed during this window. If the order is not executed during the pre-open session, it is carried forward and executed when the market opens at 9:15 am, subject to price availability and market conditions.
How does an after market order work?
Let’s walk through how an after market order works, from the moment you place it to when it gets executed:
1. You place an AMO via your broker app/terminal
You can place the order after market hours—typically anytime after 3:45 pm until around 8:58–9:00 am the next day, depending on the segment and broker.
2. The broker stores your order overnight
Since regular trading is closed (equity market hours are 9:15 am to 3:30 pm), your broker holds the order securely until the exchange starts accepting orders.
3. The order is sent to the exchange during the acceptance window
The next day, when the pre-open session begins (usually between 9:00 am and 9:07 am for equities), your broker forwards the order to the exchange.
4. Execution depends on price match and market conditions
- If your order price matches during the pre-open session, it may get executed during this window.
- If not, the order moves to the regular market session and is executed after 9:15 am, provided there is sufficient liquidity and your price conditions are met (for limit orders).
- For market orders, execution happens at the best available price once the market opens.
AMO vs regular order: Key differences
Here’s how AMOs differ from regular orders and when to use each:
| Features | After Market Orders (AMO) | Regular Market Orders |
| Timing of order placement | Placed after market hours; sent when order acceptance begins. | Placed during market hours. |
| Execution timing | Executed in the next session (pre-open or market hours). | Executed immediately at market price. |
| Execution visibility | No real-time tracking while placing the order. | Real-time price and order-book tracking available. |
| Gap risk | Can be affected by overnight news and price gaps. | Lower overnight exposure. |
| Use case | Useful for planning trades in advance. | Ideal for active, real-time trading. |
| Flexibility | Can be placed anytime outside market hours. | Requires availability during market hours. |
Types of after market orders
The types of after-market orders depend on what your broker allows during the AMO window and what the exchange accepts when routing begins. Here are the most common types you may come across:
Limit AMO
You specify a price at which you want to buy or sell. Execution happens only if the market reaches your price (or better), subject to liquidity.
Market AMO
The order is executed at the prevailing market price once it is routed to the exchange. The final execution price may differ from the last traded price due to market conditions at open.
Stop-loss AMO
You set a trigger price, and once it is reached after the order is routed, the order is activated. It then gets executed as a market or limit order, depending on the type selected.
Bracket/cover orders (where available)
These are advanced order types with built-in risk management features like stop-loss and target levels. Availability may vary, as not all brokers support these during the AMO window.
Features of after market orders
Here is a closer look at the key features and benefits of after market orders and how they can support your trading decisions:
Convenience and flexibility
You can place orders outside regular market hours, making it easier to trade at your convenience. This is especially useful if you are unable to monitor markets during the day or want to act on research done after market hours.
Ability to plan trades in advance
AMOs allow you to decide your entry or exit price ahead of time. This helps you stay prepared for the next trading session without rushing decisions during market hours.
Order modification and control
You can usually modify or cancel your AMO anytime before the market opens the next day, depending on your broker. This gives you flexibility to adjust your strategy if market conditions change overnight.
Access across market segments
AMOs are available across multiple segments such as equities, derivatives, currencies, and commodities. This makes them a versatile tool for different types of traders and investors.
Execution based on market conditions
Execution depends on price, liquidity, and whether your order matches available buyers or sellers once routed. If these conditions are not met, the order may remain pending or get cancelled based on its validity settings.
Risks of using AMO
While after market orders can be convenient, it’s equally important to understand the potential risks before using them:
Overnight price gaps
Overnight news or global events can cause stocks to open significantly higher or lower than the previous closing price. This may result in your order being executed at a level very different from what you expected.
Liquidity constraints
If there isn’t enough trading volume, your AMO may not get filled at your specified price. In some cases, the order may remain unexecuted due to limited liquidity or price mismatch.
Price uncertainty at open
Since you place the order when markets are closed, you do not know the exact opening price. This lack of real-time visibility can make AMOs feel like “blind” orders, especially in fast-moving markets.
Volatility at market open
The market can be highly volatile during the pre-open and initial trading minutes, which may lead to sharp price movements. This can affect how and when your order gets executed.
Order type limitations
Certain order types, such as bracket or cover orders, may not be available during the AMO window, depending on the broker. This can limit your ability to apply advanced risk management strategies.
Broker cut-off timings
AMO cut-off times vary across brokers and segments. Missing the cut-off window may delay your order being sent to the exchange until the next trading session.
Why AMO orders may get rejected
Understanding the common reasons for AMO order rejections can help you avoid surprises and place orders more effectively:
- Insufficient funds or holdings can lead to rejection.
- Limit price not matching market conditions may prevent execution.
- Broker-imposed price bands can cause order rejection.
- Certain stocks may be restricted due to surveillance or F&O bans.
- Low liquidity can result in rejection or non-execution.
- Orders placed outside allowed timings may be rejected.
- Incorrect order details (such as quantity or lot size) can cause rejection.
- High volatility at open may impact order acceptance.
Important things to consider before placing an AMO
Before placing an after market order, it helps to keep a few key factors in mind to make more informed and confident decisions:
- Order type: Limit orders offer better price control, while market orders prioritise execution but may lead to price uncertainty at market open.
- Validity: Day/IOC/GTC-like settings (as available) determine how long your order remains active, while GTT (Good Till Triggered) is a separate feature offered by some brokers.
- Position sizing: Align your order size with your overall risk management strategy and investment plan.
- Product type: Choose whether the order is for delivery or intraday to avoid operational issues during execution.
- Overnight news and global cues: Keep track of major news or global market movements, as they can impact opening prices.
- Execution certainty: AMO execution is not guaranteed and depends on price match and available liquidity.
- Post-open review: Check your order status after the market opens to ensure it has been executed as expected.
- Investment approach: If you are investing (not trading), you may also consider diversified options like mutual funds based on your goals and risk profile.
Example of an after market order
Let’s say a stock closes at ₹500 and you want to buy it only if it is available near ₹495. You place a limit after-market order to buy at ₹495 for a certain quantity.
The next day, if the stock opens and trades at or below ₹495 and there is sufficient liquidity, your order may get executed (fully or partially) at ₹495 or a better price. If the stock opens at ₹510 and does not trade down to ₹495, the order may not be executed.
Who may use AMO?
After market orders can be especially useful depending on how and when you prefer to trade:
- Investors who can’t monitor markets during the day.
- Working professionals who prefer trading after hours.
- Investors who plan trades in advance.
- Traders comfortable with overnight price gaps.
- Investors reacting to news after market hours.
Conclusion
An after market order is a convenient feature that allows investors to place orders outside regular market hours and have them routed when the market opens. It can help you plan trades in advance and reduce time pressure, but it does not eliminate market uncertainties such as gap risk, liquidity, and order type still play an important role in execution. Understanding what an after market order is, typical AMO windows, and the different order types can help you set clearer expectations and use AMOs more effectively in your overall investment approach.
FAQs
Can I place an AMO at market price?

Which exchanges allow after market orders (AMOs)?
AMO is a broker feature that routes orders to the exchange when the acceptance window opens; availability may differ by segment and broker configuration.
Which may suit you more: AMO or a pre market order?
It depends on whether you want the order queued well in advance (AMO) or placed closer to the pre-open session (pre market). Both can face gap risk and limited visibility before normal trading begins.
When can AMO orders be placed?
AMO placement windows vary across brokers and segments. Many brokers allow placement after market close and route orders the next day during the exchange acceptance window.
What are the benefits of AMO orders?
Convenience, planned entries/exits, and the ability to queue orders outside market hours are common benefits.
Is it prudent to place an AMO order?
AMOs can be used with clear limits and risk controls. The key consideration is that execution is not guaranteed and the opening price can differ from expectations.
Can I buy shares after 3:30 PM in India?
You can place an AMO after market close, but the order is routed for execution when the exchange begins accepting orders the next day.
Which may suit you more: AMO or a GTT order?
AMO queues an order for the next session. GTT orders are trigger-based and may remain valid until triggered, based on platform rules. The fit depends on time horizon and trigger preference.
What happens if my AMO order is not executed?
If your price conditions are not met or liquidity is insufficient, the order may remain pending or get cancelled based on validity settings and broker rules.
Are there any charges for placing an AMO?
Brokerage and other applicable charges depend on broker pricing and segment rules. Many brokers do not charge a separate “AMO fee,” but standard transaction charges can apply.
