Technical analysis is a method of evaluating securities by analyzing statistics generated by market activity, such as past prices and volume. Technical analysts do not attempt to measure a security's intrinsic value, but instead use charts and other tools to identify patterns that can suggest future activity.
The idea behind technical analysis is that market trends, as shown by charts and other technical indicators, can predict future activity. Technical analysts believe that recognizing certain chart patterns or trends can provide insight into a security's future price movements, making it a popular tool for traders in the stock, forex, and commodity markets.
It is important to note that technical analysis is not a perfect science and its predictions are not always accurate. It should be used in conjunction with other forms of analysis, such as fundamental analysis, to make informed investment decisions.
