I'm curious what the tactic is behind the all or n

I'm curious what the tactic is behind the all or nothing order CJ is talking about over on IHUB? She seems to have an order waiting @ 007 but it being an all or nothing, its not likely to trigger unless there is a lot of sell volume suddenly @ 007. It seems contrary to me, but I am a relatively newer trader/investor.

This some kinda tactic for gate watching a breakout? Just curious, thanks
