Option expiry date/price definition
Option expiry date/price
The precise date and time when an option will expire. The two most common option expiries are 10:00am ET (also referred to as 10:00 NY time or NY cut) and 3:00pm Tokyo time (also referred to as 15:00 Tokyo time or Tokyo cut). These time periods frequently see an increase in activity as option hedges unwind in the spot market.
