A variation on corridor option in which the accrual corridor is one-sided. That suggests the other side or boundary of the range is open-ended. For example, a wall option may have its band determined by a lower boundary of 50 whilst its upper boundary is infinite or non-specified. A wall option pays a given coupon amount provided that the underlying doesn’t break through the wall either to the upside or the downside, depending on the option type.
