Hello, poster~ In the foreign exchange market, currency pairs are quoted in fixed ways such as Europe and the United States, pounds and US dollars, Australian and US dollars, or US and Japanese, US and US, etc., which means that there will be no US and US prices. European and American pounds, Japan and the United States have such reversed quotations, so it seems that the dollar in front becomes a straight market - the United States, Japan, the United States and Canada, etc., such as Europe, the United States, pound and the United States, becomes a cross market. I hope the poster can understand,
