A bar chart 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 total trading range as a whole, for the bars time period.
The horizontal hash on the left side of the bar is the opening price, and the right-side horizontal hash is the closing price.
As with candlesticks a bar is simply one segment of time, whether it is one day, one week, or one hour. When you see the word ‘bar” going forward, make sure you understand what time frame it is referencing.
Bar charts are also known as “OHLC” charts, because they indicate the Open, the High, the Low, and the Close for that particular currency/commodity within that particular timeframe.
