Olsen Data has developed a new type of barrier option that they call a box option. This defines a discrete box of the price range over time through which the price of the underlying must, or must not, cross. If drawn on a chart the option looks like a box , the height of which is the price range, the length being the period over which this range is active. These can be priced as either hits or misses by the underlying. Olsen deals box options through an automated interface using a Java applet.

There's a demo available here.
