Technical Analysis/Type of Charts
Charts are the heart and soul of technical analysis. Many experienced traders wax poetically about how 'charts talk to them' and make bold statements about the future direction of a stock based on examination of price history. Yet to the untrained eye, these same graphs are but squiggles across a page with no discernible order. Beneath the surface, it is actually an accumulated history of human behavior, a voting mechanism of sorts. The technician is able to see how individuals reacted to earnings reports, economic conditions, and political ramifications over time. There is no need to re-examine those events, since informed market participants have cast their votes as prices over time reflect different expectations.
The basic data on which the chart is drawn are
- Price Band (Open, High, Low & Close)
Above data is published by the stock market on their websites and the data is also available on various other commercial portal like google and yahoo. To direct you to few of them following are the links to some of such websites:
A chart represents of the demand and supply of a stock or commodity. The horizontal axis represents time, with the price drawn as a line connecting consecutive closing values. More sophisticated charts will show more detail; bar charts also include the range from high to low, candlestick charts include the open price along with a color and fill which reflects change relative to the previous close. A chartist will examine clusters of these marks and categorize them into behavioral patterns. The nomenclature used depends on the chart style as well as the theory to describe price action. Candlestick charts have become very popular since Steve Nison published Profiting With Japanese Candlestick Charts in 1991. This approach was used to trade rice in late 1600s, and consists of such colorful descriptions such as 'spinning tops', 'evening doji star', '3 soldiers', 'dark cloud cover', or 'hammer'. There are also different ways of filtering out noise and reducing detail - Point and Figure, Renko and Kagi will combine several bars and ignore the time scale axis. What is key to any charting method and classification is the context in which the pattern appears. This is true for all sub-disciplines of technical analysis.
Types Of Charts edit
The basics of the technical analysis are chart itself, hence let us get to know some of the graphs involved in technical analysis.
1. Line Chart
A line chart is the simplest type of chart. The single line represents the security's closing price on each day.
Dates are displayed along the bottom of the chart and prices are displayed on the side(s).
A line chart's strength comes from its simplicity as it provides an uncluttered, easy to understand view of a security's price.
A bar chart displays a security's open (if available), high, low, and closing prices.
Bar charts are the most popular type of security chart.
The top of each vertical bar represents the highest price that the security traded during the period, and the bottom of the bar represents the lowest price that it traded. A closing tick (on right side bar) and an opening tick (on left side bar) designate the price that the security's trading.
3. Volume bar chart
Volume is usually displayed as a bar graph at the bottom of barchart.
