A specific type of bar chart that displays the open, high, low, and closing prices for each period. OHLC charts are very helpful to traders since they display the four main price data points, providing a complete picture of price action during a specific period of time (daily chart, hourly chart, 15-min chart...).
A less common type of bar chart is the HLC chart. The difference between the two is in the price values that are displayed. The HLC bar chart displays the high, low and closing prices. The OHLC bar chart displays all four price values, the opening, high, low and closing prices, making it a more complete bar chart.
