How to know if you are adding or taking liquity

I'm still stuck on this IB stock rates thing>>> bundled or unbundled.

What is important is if you are adding liquity or taking liquity. How do you find that out?

is it as simple as if you are selling rallies and buying dips that's adding liquity?

 

Are you increasing the bid/offer or are you lifting bid/offers?

 

Did you pay the spread?

 

i place all orders at market, so then I guess I'm taking liquity

 

if I place all orders at market, would it even be worth it to look at IB's unbundled rates?

 

No.
