There are over 900K of orders on the bid and 78K on the ask.
that's a pittance, yet there isn't a rush to grab them.
This is one of the reasons I didn't hold with the accumulation theory a while ago. Accumulation happens over a range, that's not happening here. There are very few bot trades, to me this current action screams retail traders trying to catch the bottom.
This is where a retail trader with a bit of capital can move the SP pretty quickly.
It's an interesting exercise in learning to watch times like these, as the SP can run quickly on no news or warning due to an individual traders whims if they have the weight.
