Visualize Market Trends Like A Pro
Bar charts consist of multiple price bars, with each bar illustrating how the price of an asset or security moved over a specified time period. Each bar typically shows opening, high, low, and closing prices (OHLC), though it may also be adjusted to show only the high, low, and close (HLC). To help you make informed trading decisions, we’ll break down how to read and interpret bar charts.
Key Takeaways
- A bar chart visually depicts the opening, high, low, and closing prices of an asset or security over a specified period.
- The vertical line on a price bar represents the high and low prices for the period.
- The left and right horizontal lines on each price bar represent the opening and closing prices.
- Bar charts can be color-coded: if the close is above the open, it may be colored black or green; if the close is below the open, it may be colored red.
Understanding Bar Charts
Bar charts present a collection of price bars, with each bar showing price movements for a given period. Each bar displays a vertical line illustrating the highest and lowest prices during that period. The opening price is marked by a small horizontal line on the left of the vertical line, and the closing price is marked by a small horizontal line on the right.
If the closing price is above the opening price, the bar may be colored black or green. Conversely, if the close is below the open, the bar might be colored red. Color coding helps traders spot trends and price movements with ease. Customized color settings are available in most charting platforms.
Technical analysts use bar charts—alongside other chart types like candlestick or line charts—to monitor price action. This aids in making trading decisions by analyzing trends, spotting potential trend reversals, and tracking volatility and price movements.
Interpreting Bar Charts: Insights Await!
Bar charts convey a wealth of information, aiding traders and investors in making well-informed decisions.
- Long vertical bars: Indicate a significant price difference between the high and low, showing increased volatility.
- Small vertical bars: Show little volatility.
- Large distance between open and close: Indicates a significant price move. If the close is far above the open, it shows strong buyer activity which may continue into future periods.
- Close location: The position of the close relative to the high and low provides valuable insights. For example, if the close is near the high, it indicates strong buyer activity. If an asset rallies within a period but closes significantly lower, it reveals seller domination.
Color-coded bar charts offer a quick glance into overall market trends. Uptrends are typically represented by more green or black bars, while downtrends show more red bars.
Bar Charts vs. Candlestick Charts: Choose Wisely
While bar charts and Japanese candlestick charts offer the same data, they present it differently.
- Bar Chart: Composed of a vertical line with horizontal lines on the left and right showing the open and close.
- Candlestick Chart: The vertical line shows the high and low, and a thicker portion represents the open-close range, known as the body. Different colors indicate price movements: red if the close is below the open, and white or green if the close is above the open.
Elevate Your Trading with Bar Charts
An example bar chart for the SPDR S&P 500 ETF (SPY) can help visualize how bar length and color signify market movements. During declines, bars get longer—showing increased volatility—and have more down (red) bars compared to up (green) bars. As prices rise, more green bars appear, highlighting trends visually.
To visualize trends within an uptrend or downtrend, you’ll notice a predominant color. This visual differentiation helps traders identify direction and continuity in pricing. More importantly, if more red bars signify lower prices, it reveals pullbacks or trend reversals in progress.
