After market orders (AMO) are placed in the trading platforms after the market is closed. Traders use this facility to place orders for the next trading day.
Once the after market order (AMO) is placed, it will be executed on the next trading day as per the instructions given in the order.
Market is live from 9:15 am to 3:30 pm. This facility is helpful for those traders who can not actively track the market during the live session. Intraday traders prefer to square off their position on the same day.
You can not place AMOs after the market opens.
If you place after market orders (AMO) between 9:15 AM and 3:45 PM (during the market hours), then they might get rejected by your stock broker.
AMOs can also be placed at any time during weekends and trading holidays.
Stock exchanges have specified time limits to place after market orders. AMOs can be placed on all the exchange segments.
For the equity segment the time limit fixed by NSE is 3:45 pm to 8:57 am. For BSE it’s 3:45 PM to 8:59 am.
For the future and options segment, it’s 3:45 PM to 9:10 AM.
You are requested to check with your stock broker how and when they are accepting after market orders (AMOs). Almost all stock brokers are providing this facility.
