The transaction type #交易类型入门 refers to the specific method of buying and selling activities in the financial market. Common types include spot trading, futures trading, options trading, and contract for difference (CFD) trading, among others. Spot trading is the most basic type, which involves buying or selling assets at current market prices. Futures trading is an agreement to trade at a specific price at a future date, commonly used for hedging risks.
