A
bar chart shows the closing prices, opening prices, and highs and
lows prices within the trading time period. The vertical line indicates
the currency pair's trading range as a whole. The lowest portion
of the vertical line indicates the lowest traded price, while the
top portion of the vertical line indicates the highest traded price.
The horizontal tinny line on the left is the opening price, and
the right tinny line is the closing price. In some cases, the Bar
chart also known as "OHLC" chart, because they indicate
the Open, High, Low, and Close for that particular currency.
Candlestick
chart shows the same information as a bar chart, the body in the
middle indicates the range between the opening and closing prices.
The tinny vertical line on top is the highest traded price in the
trading period, likewise the lowest portion of the tinny vertical
line is the lowest traded price. 
A
line chart draws a line from one closing price to the next closing
price. From the line chart, we can see the price movement of a currency
pair over a period of time.
