What does EX mean in MEDICAL

Expiration in trading refers to the date at which a particular asset or security can no longer be traded, or when an option contract ends. After this date has passed, traders are not able to place any orders for that particular security and any open positions need to be closed by that date as well.

Generally speaking, expiration occurs when both parties of a trade have fulfilled their obligations under the agreement. At this point, all profits and losses are settled according to the agreed terms of the trade and both parties walk away with their respective gains or losses from their trades.

Expiration typically occurs at specific dates each month for most futures contracts and options contracts, though this may vary depending on the type of asset being traded. These dates may also change slightly from year-to-year depending on factors such as holidays and weekends falling within those months.

If your option contract expires before you are ready to close it out, then you will incur any loss that has been incurred since opening the position up until its official expiration date. This means that if your position has incurred losses up until its expiration point, those losses will be applied toward your account balance instead of your potential profits from correctly predicting market conditions prior to its expiry date.

No, expired options cannot generally be reopened after their expiry date. Once an option's expiry date has been reached there is no way for traders to reactivate them nor recoup any potential losses that had been accrued prior to their official end-date.
