Working orders are orders that are placed in the market but have not yet been filled. The length of time that a working order remains active in the market depends on the type of order and the conditions set by the trader.

Limit orders and stop orders, for example, will remain active until they are either filled, canceled, or expire. Traders can set a specific expiration date for these types of orders, which can range from one day to several months, depending on the trading platform.

On the other hand, market orders are typically filled immediately, so they do not remain active in the market. Traders can also use advanced order types, such as good-till-canceled (GTC) orders, which will remain active in the market until they are filled or canceled by the trader.

It's important for traders to monitor their working orders and adjust them as needed to ensure that they remain aligned with their trading strategies and goals.
