That is nothing but analyzing stock price trends based on historical performance of the specific stock and the market. Traders use the techniques to decide when to buy or sell stocks.
Technical analysis employs models and trading rules based on price and volume transformations, such as the relative strength index, moving averages, regressions, inter-market and intra-market price correlations, business cycles, stock market cycles or, classically, through recognition of chart patterns.
