Recently, while engaging in foreign exchange trading, I suddenly realized that I am not very familiar with various currency symbols, especially when I need to quickly identify different currencies. Later, I understood that the existence of these symbols is mainly for convenience; instead of writing out "US dollar" or "USD" every time, using "$" is much faster and clearer to read.

Speaking of symbols, they can actually be quite complicated. For example, the Taiwan dollar symbol "NT$" or "￥" looks a bit like the US dollar "$", but they represent completely different currencies. I found that many people tend to confuse them, especially the "￥" symbol, which represents Japanese Yen in Japan and Renminbi in China. To distinguish clearly, it’s better to write "CNY￥" or "JPY￥". Similarly, the "$" symbol is used in over 30 countries worldwide; in the US, it's "US$", in Taiwan "NT$", in Canada "C$", in Australia "A$", and each one is different.

There are also tricks to typing these symbols on the keyboard. The Euro symbol "€" on Mac is Shift+Option+2, on Windows it's Alt+E; the British Pound "£" on Mac is Option+3; the US dollar "$" is Shift+4 on both systems. If you frequently use the Taiwan dollar symbol, typing "NT$" directly is the clearest and least error-prone.

In forex trading, you often see currency pairs like "EUR/USD," which indicates the exchange rate of the Euro against the US dollar. The first currency is called the base currency, and the second is the quote currency. It’s immediately clear that it’s asking how much the Euro is worth relative to the US dollar. Mastering these basic symbols and codes can significantly improve trading efficiency and reduce the chances of misreading the market.
