It's a controversial call to say energy prices are going to drop dramatically into next year but this is what the XLE chart is showing.
We're at a double top with monthly bearish RSI divergence, and the same structural trendline where it fell last time. My guess is it could get back down to 50. If it's a C leg it could happen faster than most would expect. 50 area would be a confluence of support - channel trendline and horizontal trendline, also IF a C leg comes, 50 is about 1.618 fib extension from the A leg.
This idea is invalid if XLE can hold above 102 on a monthly close. Good luck!
