Chart Types: Line, Bar, Candlestick, Heikin Ashi and Renko
A chart type is a choice about how to display price. Each type keeps some information and discards other information, and the ones that look cleanest are generally the ones discarding most.
How to read it
- A line chart plots closing prices only. It is the simplest and hides the range traded within each period entirely.
- Bar and candlestick charts both show open, high, low and close. They present identical data in different visual forms.
- Heikin Ashi and Renko apply transformations. What they display is derived from price rather than being price itself, which is the essential thing to understand about both.
What it does not tell you
- Smoother is not more accurate. Transformed charts look cleaner precisely because information has been removed.
- Prices shown on a Heikin Ashi or Renko chart are calculated values, not levels at which anything traded. Reading levels off them requires care.
- Chart type changes appearance, not the underlying market. A method that only works on one chart type is usually exploiting the transformation rather than anything about price.
Frequently asked questions
Which chart type is best for trading?
None is best in general. Candlestick and bar charts show the same complete information; line charts show less; Heikin Ashi and Renko show transformed values. The right choice depends on what you want to see and what you can afford to lose sight of.
What is the difference between a bar chart and a candlestick chart?
None in the data — both display open, high, low and close. The difference is purely visual: candlesticks fill the body between open and close, which many people find easier to read at a glance.
Are Heikin Ashi charts more accurate?
They are not more accurate; they are smoother because they average. The values plotted are not traded prices, which is a meaningful trade-off rather than a straightforward improvement.
Does the chart type affect my indicators?
Yes, substantially. An indicator calculated on Heikin Ashi values is being fed averaged data rather than actual closes, so its output differs from the same indicator on a standard chart.

Educational use only
This page is educational material about how a technical tool is calculated and read. It is not investment advice, not a recommendation to buy or sell anything, and not a signal service. No indicator predicts future prices. CernoQuant is a trading journal and analytics platform, not a SEBI-registered investment adviser. Trading decisions and their outcomes are yours alone.
