Difficult to give empirical example as it's more of a 'feel'.
Say the underlying (whatever instrument your following) is making it's move - you don't care which direction or if it's just ranging.
You're also shadowing (more than one) SB to see what they're doing with their price.
Although they will very roughly be following the underlying you will notice, if they have a view, they will be 'hugging' one side of the range. So, for instance, they'll be quick to move their price with the index in one direction, but a little slower in the other. You can pick up their bias from this.
Very occasionally you'll get a bonus and see them switch emphatically from either one end to the other or more often, from a middle (haven't got a view) position to emphasis.
Probably not made it much clearer, but I think you can get the gist.
