Technical analysis is a method of evaluating securities using statistical analysis of past market data like price and volume. It is used to identify patterns that can predict future price movements. Technical analysis uses tools like charts, indicators, and computer programs to analyze trends and identify trading opportunities. While technical analysis is widely used by traders, academics are divided on its effectiveness, with some studies supporting it and others finding the evidence inconclusive or inconsistent with market efficiency. Technical analysis is commonly used over shorter time frames by day traders, short-term investors, and hedgers seeking to manage risk.
