My chart "6 years of US$ gold price NY weekly close saved from ***** (red) with weekly change(Blue) in $ right axis to 11 Nov 22"posted to show HotCopper people the curiosity of how the weekly price change (blue trace) resembles an earthquake signal -
a seismogram from a seismometer.
The years up to "the ides of March 2020" are clearly characterized by smaller weekly gold price movements compared to after March2020.
