Type @all into the box and hit enter. Then, type 4 to see the day’s 10 most active options. Then, type the + sign and hit enter, to see the next ten. You can do this five times to see the top 50 most actives. This is useful, especially early in the day, as it can alert you to some contracts that are seeing unusual volume. (Note: We are working on making the box bigger and that should make it much easier to see the results.)

Good Trading!
