Yep that last bar must have included some decent buying in it,....enough to set up today's trading with a temporary supply vacuum in place, within the range of the previous downbar.
I don't know how much upside it will have in it, but the higher retail involvement may potentially spoil the party somewhat, as they may sell a bit randomly.....what should happen is that price will move higher until 'normal' supply resumes to balance the regular 'day to day' demand, and at that level, it often marks the position of the creek for future reference (and generally price will soon dip lower again once that point is reached, and come back and test the strength of the downbar)
