American line charts are among the most widely used chart types in technical analysis, standing alongside candlestick and line charts as a core tool for traders. Known for their clean, minimalist design, they provide a clear visual representation of price movement over a given time period—specifically, the open, high, low, and close (OHLC) prices. Their simplicity makes them especially valuable for traders who want to reduce visual clutter while still accessing essential market data.
This guide will walk you through everything you need to know about American line charts, from their structure and benefits to practical setup tips and how they compare with other chart types like candlesticks. Whether you're a beginner or an experienced trader, understanding this chart type can enhance your market analysis and decision-making.
What Is an American Line Chart?
An American line chart—also known as an OHLC bar chart—displays price movements using vertical lines that represent the full price range of an asset during a specific period. Each line consists of:
- A vertical line indicating the high (top) and low (bottom) prices.
- Two small horizontal ticks: the left tick shows the opening price, and the right tick shows the closing price.

For example, if you're viewing a daily chart, each bar reflects the opening, highest, lowest, and closing prices for that trading day. This allows traders to quickly identify volatility (via the length of the bar) and momentum (by comparing open and close).
These bars are often color-coded: typically green when the closing price is higher than the opening price (bullish), and red when it’s lower (bearish). Some platforms allow customization of these colors based on personal preference or trading strategy.
The clarity of American line charts makes them particularly effective when analyzing multiple assets simultaneously or when combining them with technical indicators such as moving averages, RSI, or MACD.
American Line Chart vs Candlestick Chart: Key Differences
While both chart types convey the same core data—open, high, low, and close—they differ significantly in visual presentation and analytical utility.
Advantages of American Line Charts
- Minimalist Design: The thin vertical bars take up less space on the chart, allowing for cleaner integration with overlays and drawing tools.
- Focus on Price Extremes: Because the main body shows the full high-to-low range, these charts emphasize volatility and extreme price levels—ideal for strategies focused on breakouts or support/resistance zones.
- Customizable Data Display: You can choose to hide the open price and display only HLC (High-Low-Close), which some traders prefer when they believe opening prices are less significant than intraday extremes.
Advantages of Candlestick Charts
- Visual Intuition: Candlesticks use wide "bodies" to represent the open-to-close range, making it easy to see bullish or bearish pressure at a glance.
- Pattern Recognition: Candlestick patterns—such as doji, hammer, engulfing, and morning star—are widely studied and used in technical analysis. These formations can signal reversals or continuations.
- Emotional Insight: The size and shape of candle bodies and wicks offer insight into market psychology and trader sentiment.
However, candlesticks can sometimes create visual noise, especially on shorter timeframes or when many indicators are applied. In contrast, American line charts offer a more streamlined view that supports precise technical work without distraction.
How to Enable American Line Charts
Most modern trading platforms—including popular ones like TradingView—support American line charts. To switch to this chart type:

- Locate the chart type menu in the top toolbar.
- Select "Bar Chart" or "OHLC"—this is the standard name for American line charts on most platforms.
Once selected, all current price data will automatically convert into bar format. You can toggle back at any time to compare visualizations.

Customizing Your American Line Chart Settings
To get the most out of American line charts, consider adjusting the following settings based on your trading style:
1. Color Based on Previous Close
When enabled, this feature determines the bar color by comparing the current close to the previous close:
- Green (or up color) if today’s close is higher than yesterday’s.
- Red (or down color) if it’s lower.
This setting shifts focus from intra-period movement (open vs. close) to inter-period momentum, which can be useful for trend-following strategies.
2. HLC Mode (Hide Open Price)
This option removes the left horizontal tick (open price), displaying only high, low, and close. It's helpful when you want to de-emphasize opening gaps or when analyzing markets where opening auctions may distort initial pricing.
3. Up/Down Colors
You can customize the colors for rising and falling bars. While green/red is standard, some traders use neutral tones like blue/gray to avoid emotional bias.
4. Line Thickness
Adjusting bar thickness improves readability, especially on smaller screens or dense charts with many indicators.
These settings are typically found under the “Settings” or “Style” tab in your charting platform under the “Bars” or “OHLC” section.
Why Traders Choose American Line Charts
American line charts are favored by technical analysts for several reasons:
- Clarity: They eliminate visual distractions while preserving all critical price data.
- Compatibility: Work seamlessly with trendlines, Fibonacci retracements, channels, and automated indicators.
- Efficiency: Ideal for scanning multiple assets quickly due to compact design.
- Historical Use: Long-standing presence in financial markets gives them credibility among institutional traders.
