The last trading day for an equity option series is the Wednesday preceding the last Friday of the month.
In the event that this day is not a TASE trading day, the last trading day will be the first trading day preceding that Wednesday.
Examples:
- The last Friday in May was May 25th. Accordingly, the settlement price was set on Thursday, May 24th, and the last trading day was Wednesday, May 23rd.
- The last Friday of April was April 27th. Since neither April 25th nor April 26th were trading days that year, the settlement price was set on Tuesday, April 24th and the last trading day was Monday, April 23rd.
