I use tradingview.com a lot for my own charts. Eg. XAUJPY - XAUAUD etc.. If a currency is stronger/weaker then Gold etc.. Works well.
Another example is that the currency index of every currency.
Now, by error I just came across the '. Of all the weeks on tradingview I have never come across this chart and did not even know a World Currency unit existed.
If any knows about it, I would love to know. Not positive if its a index of the currencies. I have included a pic.
Contained is the AUD/ daily chart.
