Definition of Bar Charts
A bar chart is a graphical representation that illustrates the price movements of an asset or security over a specified time period. Each bar consists of four key components:
- Opening Price - The price at the start of the period.
- High Price - The maximum price reached during the period.
- Low Price - The minimum price during that time.
- Closing Price - The ending price at the close of the period.
