Technical analysis focuses on the price movements, trends, and volume of securities rather than their intrinsic value, using historical data and patterns to identify entry and exit points. Common techniques include analyzing charts like candlestick patterns, identifying support and resistance levels, determining upward and downward trends, and using indicators like moving averages, MACD, and stochastic oscillators to identify overbought and oversold conditions. The goal is to predict future price movements based on the collective actions of investors driving supply and demand.
