Having introduced technical analysis conceptually in the previous unit, this unit explores the practical starting point for any technical analysis: the chart itself. Different chart types display the same underlying price data in different ways, each with distinct advantages.
This overview introduces five areas covered in this unit: line charts, bar charts, Japanese candlestick charts, Heikin-Ashi charts, and how to think about which chart type suits which purpose.
This is general educational content. It does not recommend any specific chart type as universally superior, since suitability depends on individual preference and analytical approach.
Why Chart Type Matters
All chart types are built from the same underlying price data, but they present that data differently, emphasizing different aspects of price behaviour. Choosing a chart type is one of the first practical decisions in applying technical analysis, directly affecting how price action, trend, and market structure (covered in the previous unit) are visually interpreted.
What's Covered in This Unit
- Line chart — the simplest chart type, connecting closing prices.
- Bar chart — a more detailed chart showing open, high, low and close.
- Japanese candlestick chart — the most widely used chart type in retail trading, explored in depth in the following lesson group.
- Heikin-Ashi overview — a modified candlestick chart designed to smooth price movement.
- Which chart type suits which purpose — practical guidance for choosing between them.
Building Toward Candlestick Analysis
This unit introduces Japanese candlestick charts at a general level, since they are the primary chart type used throughout the rest of this Technical Analysis module — including the dedicated candlestick lessons that follow later in this Chart Foundations group.
Summary
Different chart types — line, bar, Japanese candlestick, and Heikin-Ashi — display the same underlying price data in different ways, each emphasizing different aspects of price behaviour. This unit introduces each type individually before closing with practical guidance on which chart type suits which analytical purpose.
Frequently Asked Questions
No, each has different strengths, and suitability depends on individual preference and the specific type of analysis being performed, covered in the final lesson of this unit.
