The document discusses moving averages, which are technical indicators used to analyze financial data trends. A moving average calculates the average price of a security over a specified period of time to smooth out price fluctuations and make trends easier to identify. There are two main types: simple moving averages, which give equal weight to all data points; and exponential moving averages, which give more weight to recent data points. Moving averages are used to determine the direction of the current trend and generate buy/sell signals when short-term averages cross above or below long-term averages. Popular periods used include 10, 20, 50, 100 and 200 days.
