Options

Expiration

Also called: expiry, dte

The date an option contract ends.

Every option has an expiration date. After it, the option is either exercised (if in the money) or gone (if not). "DTE" means days to expiration. Sellers often use 21 to 45 DTE to capture fast time decay without tying up capital too long. 0DTE options expire the same day.

For example

A 35 DTE put expires in 35 days. If the stock is above your strike then, the put expires worthless and you keep the full premium.
