Bar Charts

bar chart is a little more complex. It shows the opening and closing prices, as well as the highs and lows. The bottom of the vertical bar indicates the lowest traded price for that time period, while the top of the bar indicates the highest price paid.
The vertical bar itself indicates the currency pair's trading range as a whole.
The horizontal hash on the left side of the bar is the opening price, and the right-side horizontal hash is the closing price.

Open: The little horizontal line on the left is the opening price
High: The top of the vertical line defines the highest price of the time period
Low: The bottom of the vertical line defines the lowest price of the time period
Close: The little horizontal line on the right is the closing price
