Trading operations involves buying and selling company shares through a stock exchange to earn profits. Investors open a trading and demat account with a broker, analyze market trends, and place buy or sell orders. Trades are executed based on market price or set limits. Share prices fluctuate due to company performance, economic indicators, and global events. Traders can choose between short-term trading or long-term investing. Profits or losses are realized when shares are sold. Regulatory bodies like SEBI (in India) oversee market activities to ensure transparency and fairness. Effective share trading requires research, strategy, and risk management.
