GBR has seen a parabolic 3000% gain & more since 2018, very odd considering Gold is only up approximately 70% in a similar time frame. I guess gold miners & gold don't necessarily correlate 100%.
GBR appears to be trading in a descending channel, and on the RSI there's a noticeable double top / Head & Shoulders, where I have placed the blue human icon represents the head of the H&S. The red arrow on the RSI is possibly a double top.
On a long term chart it appears as though the RSI has topped multiple times but the price has continued to rise, thus creating a bearish divergence.
