Take Europe, America, Australia, America and Japan as examples to talk about the essence of money:
Europe and the United States: Europe and the United States are the currency pairs we often make. The spread is very small and the trend is very stable, which is suitable for wave analysis. We can wait for the right trading signal to make short-term, band or trend orders.
Pound beauty: Pound beauty is not stable enough, the price difference is large and the range is large (now the range is smaller than that in Europe and America). Short-term operation is not cost-effective, which is most suitable for band operation.
Australia and the United States: As the Australian dollar is a commodity currency, it has a strong relationship with commodity prices. Like gold, it is suitable for making trend sheets.
USA and Japan: Surgery is not recommended. The intraday fluctuations in the United States and Japan are very small. Japanese yen, US dollar and Swiss franc are all safe-haven currencies. When the market is in a bad mood, the yen will rise, but the Japanese government does not want the appreciation of the yen to weaken export competition and will intervene in the foreign exchange market.
I won't elaborate on the rest. The cross is actually very good, depending on personal preference.
