A basic introduction to the market involves understanding market time, lot size, economic data, and data sources. Market time refers to trading hours, like those of the New York Stock Exchange. Lot size is the standardized quantity of a financial instrument, such as one share in the stock market. Economic data includes statistics like GDP and inflation, which reflect economic health and influence markets. Reliable data sources include government agencies, financial news organizations, and stock exchanges. These elements help investors make informed decisions and assess market opportunities.
