Its a difficult one. Ways to trade it could include buying at a test of the low with a stop underneath (betting on a failure), shorting a breakdown or shorting if it makes it back to the top of the pattern. That could be some way off, but something like that
maybe could play out.
Resource investor - is this the ending phase?
No there is no trigger on a top on the current upward move in the pattern, other than the pattern top itself. I would have thought for short term swing traders selling rallies seems the better risk reward option than buying dips for the time being. Taking out some resistance (e.g. 5250), regaining the 200 day MA would paint a more bullish picture I think.
