During 1900s there existed methodologies of technical analysis in US as well, even though the methodologies are different, all underlying principles are same or similar. The basic principles include price is important than asking why it has come. The price will be a function of all the known information. The financial market always moves with the expectation and feelings of the buyers and sellers. All the movements in the markets including buying and selling are basically guided by the desire to make profit. The actual market price need not reflect the actual worth or underlying value.

Understanding the candlestick chart
Candlestick is generated from the data consisting of Open, High, Low and Close prices of the stocks for the period you want to do the analysis. Most of the investors like to get the candlestick charts depicting the most recent and current OHLC data. Candlestick charts contain filled regions and unfilled regions. The filled region is known as the body of the chart and the unfilled region or region with the thin lines above and below the body are regions of high and low fluctuations known as shadows. If you want to read the candlestick chart, you can see that the price movements in the body region are more consistent and mostly risk free for investment. When the market is either in high or low shadow region, you have to take risks much in investments.
In the candlestick charts candlesticks are drawn from the open price to close price. One should know the convention of candlestick drawing to analyze and interpret perfectly the charts. If the stock close at a higher price than that of its opening price a hollow candlestick is drawn with the body bottom showing the opening value and the top of the body showing the closing price. In the other case of the market, when the closing price is less than the opening price, a filled candlestick will be drawn with larger value of open at the top and the close at bottom of the body. Many times the green candlestick is used instead of a hollow bar (increase in stock price during the period) and the red bar substitutes the filled bar – showing loss of value.
