As I've written in the title, this resistance is very old, I had it drawn for a long time, I didn't think it was still valid but it's currently working as resistance. Moreover there's a bearish DIV on 4h RSI and, always at the same timeframe, VLPR shows control line is 20% lower than current price. I think a retracement is most likely than another leg up here.
As you can see XPR went +114% after the breakout of that descending channel, a price drop would be acceptable but in the long run this will go over his previous ATH.
Stay focused.
