Along the lines of scenario B, when the PRZ proves to be durable like this one, demand is whittled away and the likelihood of a reversal increases. Thursday's BoE decision will likely be decisive for this pattern, one way or another.
PRZs, no matter how symmetrical the pattern's measurements, do not always produce reversals. Where they don't, this type of range activity can often be observed. You could contend there is no such thing as a "busted" because they have multiple trading applications beyond producing simple reversals. The key is to draw well, delineate levels of interest, look for validation of those levels and have a plan for continuation and range trades as well as reversals.
