What Happens to Pending Orders During a Trading Halt?

If you already have a pending buy or sell order when a stock enters a trading halt, the order will usually remain active unless you cancel it or it expires according to its order type. The exact handling of pending orders depends on the rules of the exchange and the order instructions you originally selected.

For example, if you placed a limit order before trading was halted, the order may remain in the order book or pending for the reopening process. However, it cannot be executed while trading is paused because no transactions are taking place. Once the exchange announces that trading has resumed, eligible orders may participate in a reopening auction or reopening process before continuous trading resumes.

If your order is a Good-Till-Cancelled (GTC) order, it generally remains active across trading sessions until it is executed, cancelled, or reaches its expiry date. A Day Order, on the other hand, will normally expire at the end of the trading day if it has not been executed.

In many regulatory trading halts, investors may also be able to modify or cancel eligible pending orders while the halt is in effect. This allows you to adjust your investment strategy if important news is released during the pause. However, once trading resumes, orders are executed according to price priority, order type, and available market liquidity—not according to when you expected the trade to occur.
