1. Line Chart
   In line charts price is displayed as a point in the map. The consequent price points connect through a line called price line. This type of chart is characteristic of the trend of the price of the currency but provides little supplemental information. This type of charts is rarely used by modern traders.
   A line chart is simply a graph of the value of a currency taken at regular time intervals based on current prices.
   
   
   
   
   
2. Bar Chart
   A Bar Chart is one of the most popular charts. It contains plenty of information about the price movement of the currency pair. On a daily bar chart each bar represents one day's activity. The vertical bar is drawn from the day's highest price to the day's lowest price. Closing price and opening price are represented by ticks on the bar.
   Bar chart is graphic representation of price action using a vertical bar to connect the highest price to the lowest price during a period. The opening price is displayed as a horizontal line on the left side of the bar. The closing price is displayed as a horizontal line on the right side of the bar. Bar Charts can be constructed for any time period in which prices are available. Traditionally, the most popular time interval for bar chart is hourly chart. However, since the wide availability of the real time prices, it is common to use smaller time interval such as 30 minutes, 15 minutes, 5 minutes, 1 minute.
   
   
   
   
   
3. Candlestick Charts
   Candlestick is close related to bar chart but it also contains price direction information. The candlestick bar consists of the body and the shadows. Candlestick charts are on record as being the oldest type of charts used for price prediction. They date back to the 1700's, when they were used for predicting rice prices. During this period in Japan, Munehisa Homma become a legendary rice trader and gained a huge fortune using candlestick analysis. He is said to have executed over 100 consecutive winning trades.
   You can spot trends more quickly with candles by looking for whether the candles are clear or colored. Within a trend, you can easily tell what a stock did in a specific period.
   

Opening and closing price makes up the body of the candlestick. When the opening price is lower from the closing price the body is left blank or white. When the opening price is higher from the closing price the body is filled with color (this color depends on the trading platform).
Upper shadows shows the high of the price and lower shadow shows the low of the price for the time span the trader selected in his chart. The most important thing is that candles are vital for spotting reversals.

These reversals are usually short term - precisely the kind the swing trader is looking for. When traditional technical analysis talks about reversals, usually it is referring to formations that occur over long periods of time. Typical reversal patterns are the "double top" and the "head and shoulders." In defining them, these involve smart money distributing their shares to novice traders and normally occur over weeks or even months.
