An Introduction to Technical Analysis

Michael J. Schill

Technical stock analysis uses past prices and trading volume or both to predict future prices. A broad range of techniques such as chart analysis, moving averages, and other filters and oscillators can be used to identify predictable patterns in stock prices. The conventional wisdom is that stock-price patterns emerge from systematic psychological behavior of market participants. This note . [Show full abstract] provides an overview of some common analytical tools for identifying trading opportunities.

A study on technical analysis of s&p cnx nifty index

Technical analysts do not attempt to measure a security's intrinsic value; instead they look at stock charts for patterns and indicators that will determine a stock's future performance. The use of past performance should come as no surprise. People using fundamental analysis have always looked at the past performance of companies by comparing fiscal data from previous quarters and years to . [Show full abstract] determine future growth. The difference lies in the technical analyst's belief thatsecurities move according to very predictable trends and patterns. These trends continue until something happens to change the trend, and until this change occurs, price levels are predictable. There are many instances of investors successfully trading a security using only their knowledge of the security's chart, without even understanding what the company does. However, although technical analysis is a terrific tool, most agree it is much more effective when used in combination with fundamental analysis. The technical analysis reveals the peaks, bottoms, trends, patterns and other factors affecting a stock‘s price movement and then makes buy/sell decisions based on those factors. The tools namely RSI and EMA have been used to predict the index price movement of S&P CNX Nifty.

One of the major duties of financial analysts is technical analysis. It is necessary to locate the technical patterns in the stock price movement charts to analyze the market behavior. Indeed, there are two main problems: how to define those preferred patterns (technical patterns) for query and how to match the defined pattern templates in different resolutions. As we can see, defining the . [Show full abstract] similarity between time series (or time series subsequences) is of fundamental importance. By identifying the perceptually important points (PIPs) directly from the time domain, time series and templates of different lengths can be compared. Three ways of distance measure, including Euclidean distance (PIP-ED), perpendicular distance (PIP-PD) and vertical distance (PIP-VD), for PIP identification are compared in this paper. After the PIP identification process, both template- and rule-based pattern-matching approaches are introduced. The proposed methods are distinctive in their intuitiveness, making them particularly user friendly to ordinary data analysts like stock market investors. As demonstrated by the experiments, the template- and the rule-based time series matching and subsequence searching approaches provide different directions to achieve the goal of pattern identification.
