Glossary entry
In financial charting, an OHLC bar chart represents each interval's open, high, low, and close using a vertical bar and short horizontal marks. The vertical range shows the period's extremes, while the marks indicate opening and closing levels. It condenses price information without showing the chronological path of trades inside the interval.
Illustrative example
A bar reaching from 48 to 53 shows that period's low and high. Side marks at 50 and 52 indicate its opening and closing prices.
What to consider
Confirm the interval and plotting convention. The same bar can result from very different intraperiod paths and trading conditions.
