What are forms of trade?

Forms of trade primarily include barter, where goods and services are directly exchanged without using money; retail trade, which involves selling goods to consumers; wholesale trade, where goods are sold in bulk to retailers or other businesses; and e-commerce, which encompasses buying and selling goods or services online. Additionally, international trade involves the exchange of goods and services across borders, while fair trade focuses on equitable trading conditions for producers in developing countries. Each form plays a crucial role in the global economy.
