Three type of charts which are used in technical analysis. Candle sticks, Line, Bar. Line charts are good over 2 year period but not for tracking short term movements
Bar charts help to avoid the above cons but they are not appealing and fast.
Candlesticks can help identify immediately short term trends. Demand and supply drive the stock price with reference to the Stock’s earning ability. Fundamental analysis is a powerful tool but available only for bulwarks. Technical analysis can be used by common men.
