Im not sure if that is the correct term for what I do, I just call it “harmonic”.
The main Idea is you chose a few currencies but you make sure they are all traded against the other currencies in a portfolio.
In my example I chose AUD, USD, CAD, EUR so I trade the following pairs:
EURUSD
EURAUD
EURCAD
USDCAD
AUDUSD
AUDCAD
As you can see, each currency is equally represented in 3 pairs. Any thoughts or opinions?
