On the way up since 78, we've had bursts of volume on 2 pt intervals, which indicates this is being powered by stops rather than genuine buyers. Once it's all done (connect the previous 2 peaks this week and the chart indicates we are very close to a key resistance, which, believe it or not is at around 83.75 again!), we might start going down just fast as we've come up. Internals are still a bit shaky so this isn't the time to go long for a small trader like me. If big institutions want to push it up from now on to make this a trend day, so be it.
