This is Gold Normalized against the US dollar in arbitrary units, which solely highlights the empirical strength of gold and ignores the strength or weakness in the US dollar
I have also used Heikin Ashi to eliminate whipsaws for better trend identification,
and I've also added a regular GOLD/Dollar line in the background (purple) for comparison
The purpose of this chart is to point out that the recent bounce in (Gold/USD) has more to do with USD being weak than GOLD being strong.
This is an experimental method of objectively looking at the strength of GOLD, good luck trading :D
