On the last trading day of expiring series, trading is possible until 16:00 CET. The series are settled against the EDSP (Exchange Delivery Settlement Price) which is calculated between 15:30 and 16:00 CET
AEX-index weekly options
The trading symbol of weekly options always start with AX, followed by a number which indicates the Friday of the expiry month, so either 1, 2, 4 or 5. There is no separate AEX weekly option class expiring on the third Friday of the month, as the week leading up to that day is the last week of trading in the AEX monthly options expiring that month.
