IB attached stop order settings

https://www.interactivebrokers.com/en/software/tws/twsguide.htm

In the above example, under the attached stop order heading, they choose a trailing stop as the order type but then on the bottom choose 0.00 as the trailing amount.
This makes no sense to me.

Can anyone please help me understand this or is this an oversight?

 

The link above doesn't work.

Please see the screen capture below.

Many thanks for any help.

 

The numbers can be changed by the user. You can just change it to your pref setting.
