#交易对 Trading Pair refers to a combination of two assets that can be exchanged for each other on a cryptocurrency exchange, such as BTC/USDT (Bitcoin to Tether). The trading pair is divided into base currency (BTC) and quote currency (USDT), indicating the price to purchase the base currency with the quote currency.

Types of trading pairs include:

- Major trading pairs (e.g., BTC/USDT) — high liquidity, small spreads;

- Altcoin trading pairs (e.g., SHIB/ETH) — lower liquidity, high volatility;

- Fiat currency trading pairs (e.g., BTC/USD) — directly exchanged with fiat currency.
