There are several common types of trading practices that businesses may engage in: 1. Spot Trading: This involves the immediate exchange of goods or financial instruments for cash. 2. Futures Trading: In this practice, parties agree to buy or sell an asset at a future date at a predetermined price. 3. Options Trading: This involves contracts that give the buyer the right, but not the obligation, to buy or sell an asset at a set price before a certain date. 4. Algorithmic Trading: This uses computer algorithms to execute trades based on pre-defined criteria, often used in stock markets. 5. Day Trading: This practice involves buying and selling financial instruments within the same trading day to capitalize on short-term market movements.
