Trading is the buying and selling of financial assets like stocks, bonds, currencies, or commodities to earn a profit. It works by leveraging market fluctuations, where traders aim to buy at a lower price and sell at a higher price. Trading can occur on exchanges or over-the-counter markets and is conducted by individuals or institutions using platforms and tools. Key strategies include day trading, swing trading, and long-term investing. Platforms like tv.youtube.com/start provide educational content, market analysis, and live updates to help traders make informed decisions, ensuring they stay ahead in the dynamic world of financial markets.
