An OHLC bar chart shows a bar for each time period the trader is viewing. So, when looking at a daily chart, each vertical bar represents one day’s worth of trading. The bar chart is unique as it offers much more than the line chart such as the open, high, low and close (OHLC) values of the bar.
The dash on the left represents the opening price and the dash on the right represents the closing price. The high of the bar is the highest price the market traded during the time period selected. The low of the bar is the lowest price the market traded during the time period selected.
- The green bars are known as buyer bars as the closing price is above the opening price.
- The red bars are known as seller bars as the closing price is below the opening price.
In either case, the OHLC bar charts help traders identify who is in control of the market – buyers or sellers. These bars form the basis of the next chart type called candlestick charts which is the most popular type of Forex charting.
