I've been trading for over a decade, and this is the <b>first time I've ever seen</b> a morning range this tight on the spooz.
It would seem as though these spikes during the lunch hour are clearly driven buy stops being hit in the index futures, as all good traders are taught to always place your stops.
What I see is offers being pulled and small lots tapping the offer higher, but the bid is getting hit with size as it moves up.
