On a day where QE 4 was supposedly in the mix, long term treasuries sold off, meaning GBN.V share prices should have risen as a consequence. The sellers are in complete control here, with no buyers in sight, save a handful. They will defend their positions to the hilt now.
This is not a market where price discovery makes the trade, rather that we have a very crooked, biased pricing favouring the absence of the 'no down-tick' rule.
