The biggest help in trading is provided by Technical analysis. It is very necessary to learn either fundamental analysis or Technical analysis to perform better in trading. Technical analysis is very easy to master and learn.
Technical Analysis is an art in which forecasting of price movements is done based on historical data i.e. price and volume. It is not an exact science where you can get result on an absolute basis but it is an art where everyone performs the analysis differently with the help of technical components like indicators, patterns, trendlines etc. on a chart.
Technical analysis is a very easy way to do chart analysis as compared to fundamental analysis. I found a great article which covers in-depth knowledge about Technical analysis. For a beginner or advanced trader, it will provide you with good exposure to Technical analysis.
