An OHLC (Open-High-Low-Close) chart is a type of financial bar chart that represents the opening, highest, lowest, and closing prices of a financial instrument over a specific period. Each bar on the chart encapsulates this information for a single time interval, providing a clear visual of price movements.
Components of an OHLC Chart
- Open: The price at which the instrument opened trading for the period.
- High: The highest price achieved during the period.
- Low: The lowest price achieved during the period.
- Close: The final price at which the instrument was traded at the end of the period.
How to Read an OHLC Chart
Reading an OHLC chart involves analyzing the four main components represented by each bar:
- Opening Price: Indicated by a horizontal tick on the left side of the vertical bar.
- Closing Price: Indicated by a horizontal tick on the right side of the vertical bar.
- High Price: The topmost point of the vertical bar represents the highest price during the period.
- Low Price: The bottommost point of the vertical bar represents the lowest price during the period.
Example of an OHLC Chart
Imagine a bar representing data for a specific trading day:
In this context, the bar would start at $100, peak at $110, drop to $95, and close at $105.
