Bar Charts

Bar charts also known as OHLC charts are used in charting and studying of chart patterns.

It is one of the most popular forms of stock charts and was the most widely used charts before the introduction of candlestick charts.

Each bar represents a symbol which is made up of OHLC data which are typically used to illustrate price movement of a financial instrument over a period of time.

The height of each OHLC bar indicates the price range for the given period with the high being the topmost point of the bar and the low to be the lowermost point of the bar.


However, the time period could be either  1 minute, 5 minutes, 15 minutes, 1 hour, 4 hour, 1 day, 1 week, 1 month etc and each has its own bar as per the desired time period and accordingly it can be 1 minute bar, 1 day bar or 1 week bar.

Moreover, some charting software use colors to indicate bullish or bearishness of a bar vis-a-vis to the close of the previous bar.

This makes the OHLC bar chart much similar to the candlestick chart, but it lacks clarity as compared to the candlestick chart

How are they constructed?


To construct bar chart, the OHLC data is used and hence the name OHLC chart.

In that vertical line, a small horizontal line (small tick) will be attached both on the left and the right-hand side.

The one on the left side indicates the opening price while one on the right-hand shows closing price.

The bars will provide different colors depending upon whether the prices increased or fell in that period.

For instance, the red color indicates a down bar as compared to the previous bar while green candle indicates up bar vis-a-vis the previous bar.
