A Good-Till-Date (GTD) order lets you place a buy or sell order on stocks, ETFs, or futures and options contracts, that stays active until a date you choose, instead of expiring at the end of the trading day like a regular order.  

Here's how it works: you set your price and pick a validity date. If your price condition is met before that date, the order is sent to the exchange and executed. If not, it's automatically cancelled once the validity date passes. No action needed from you.  

With GTD order, you don't have to re-enter the same order every morning or keep watching the market. Set it once, and let the order do the waiting.
