Introduction to Renko and Range Bars

What is Renko?

Renko charts, originating from Japan, are a type of charting technique that focuses solely on price action. Unlike traditional time-based charts, Renko charts filter out minor price movements and represent price action using bricks. Each brick represents a fixed price movement, and a new brick is formed only when the price exceeds the brick’s range. Renko charts provide a simplified view of price action, making trends more apparent and reducing the impact of small fluctuations.

What are Range Bars?

Range Bars, on the other hand, are constructed based on price range rather than time intervals. With Range Bars, traders specify the desired range for each bar, and a new bar is formed when that price range is reached. The height of each bar remains constant, allowing traders to easily identify patterns and trends in price action. Range Bars are particularly useful for capturing volatility and eliminating time-based noise.

The common goal: Reducing noise, revealing trends

Both Renko and Range Bars share a common objective: to filter out market noise and provide traders with a clearer view of price trends. By eliminating minor price fluctuations, these charting techniques help traders focus on significant price movements, enhancing the accuracy of their analysis and decision-making.

Renko Charts

Construction and Features

Renko charts consist of bricks that represent price movements. The size of the bricks can be customized based on the trader’s preference and the underlying asset’s volatility. When the price exceeds the brick size, a new brick is formed in the respective direction. Renko charts are effective in smoothing out price action and making trends more apparent.

Advantages of Renko Charts

Renko charts offer several advantages to traders:

– Clear trend identification: Renko charts make it easier to identify trends as they filter out noise and focus solely on significant price movements. Traders can visually see the direction of the market more clearly.
– Simplicity: Renko charts provide a straightforward visual representation of price action, making them ideal for traders who prefer simplicity and ease of use. The absence of time-based intervals simplifies the analysis process.
– Reduced emotional trading: By removing minor price fluctuations, Renko charts can help traders stay focused on the bigger picture, reducing emotional reactions to short-term price swings.

Limitations of Renko Charts

While Renko charts have their advantages, they also have some limitations:

– Lack of time-based information: Renko charts do not take time into consideration, which may be a disadvantage for traders who rely on time-based analysis or who trade based on economic news releases. The absence of time-related data may lead to missed opportunities.
– False breakouts: Due to the fixed brick size, Renko charts may occasionally produce false breakouts, where the price briefly exceeds the brick’s range before retracing back within it. Traders need to be cautious and use additional indicators to confirm breakouts.
– Less detailed information: Renko charts provide a simplified view of price action, which means traders may miss out on some detailed information available in other charting methods. Traders relying on specific candlestick patterns or complex indicators may find Renko charts limiting.

Range Bars

Construction and Features

Range Bars are constructed based on price range, offering a different perspective on price action. Traders specify the desired price range for each bar, and a new bar is formed when that range is reached. The height of each bar remains constant, regardless of time, allowing traders to easily identify patterns and trends.

Advantages of Range Bars

Range Bars offer several advantages to traders:

– Enhanced volatility measurement: Range Bars adjust to market volatility, allowing traders to better gauge price action and identify changes in market dynamics. Traders can capture price movements more accurately.
– Accurate pattern identification: Range Bars provide a clearer representation of price patterns, making it easier to identify chart patterns, support and resistance levels, and breakouts. Traders can more effectively analyze price action and make informed trading decisions.
– Improved risk management: With Range Bars, traders can set precise stop-loss levels based on price ranges, enabling better risk management and trade execution. Range Bars help traders define risk more precisely.

Limitations of Range Bars

Range Bars also have certain limitations:

– Time intervals not represented: Range Bars do not consider time intervals explicitly, which can be a disadvantage for traders who rely on time-based analysis or use indicators that incorporate time. Time-based factors and news events may be overlooked.
– Limited availability: Some charting platforms may not offer Range Bars as a standard charting option, making it necessary for traders to find or develop custom solutions. Traders need to ensure their chosen platform supports Range Bars or explore alternative platforms.
– Less popular: Compared to traditional time-based charts, Range Bars are less commonly used, which may limit the availability of educational resources and community support. Traders may need to seek out specialized resources or connect with other traders who use Range Bars.

Comparing Renko and Range Bars

Chart Clarity

Both Renko and Range Bars excel in providing unambiguous chart patterns. By filtering out noise and minor fluctuations, both techniques make it easier for traders to identify trends and important price levels. Renko charts, with their simplified brick-based representation, are effective at highlighting overall trends, while Range Bars offer the advantage of adjusting to market volatility and capturing precise price movements.

Trend Identification

Renko charts excel in identifying trends due to their simplicity and focus on price action. They provide a clear visual representation of bullish and bearish trends, allowing traders to make more confident decisions. Range Bars also aid in trend identification by displaying price action in a more precise manner. The constant bar height and the ability to capture volatility make it easier for traders to spot support and resistance levels, trend reversals, and chart patterns.

Volatility Measurement

Range Bars have an edge when it comes to volatility measurement. The ability to adjust bar size based on price ranges allows traders to capture market volatility more accurately. Range Bars provide a dynamic representation of volatility and can be particularly useful for traders who incorporate volatility analysis into their strategies. Renko charts, on the other hand, do not directly represent volatility, focusing more on price movement patterns.

Time Considerations

Renko charts completely ignore time intervals, which can be advantageous for traders who want to focus solely on price action. However, time-based analysis and the consideration of economic news events are critical to some trading strategies. Renko charts may not be suitable for traders who rely heavily on time-specific analysis or trade based on news releases. Range Bars indirectly incorporate time through price movement, as bars are formed based on price ranges, but time itself is not explicitly displayed. Traders need to assess whether time-based factors are crucial to their trading approach.

Personal Preference

The choice between Renko and Range Bars ultimately boils down to personal preference and trading style. Traders should consider their goals, timeframes, trading strategies, and preferred indicators before deciding on a charting technique. Experimenting with both methods on historical data or through paper trading can help traders understand which approach aligns better with their objectives and provides them with the necessary insights to make good trades.


Renko and Range Bars are both valuable charting techniques that help traders filter out noise and focus on significant price movements. Renko charts provide a simplified view of price action, making trends more apparent, while Range Bars offer volatility-adjusted bars that aid in accurate pattern identification and risk management. Traders should carefully assess their trading style, objectives, and preferred indicators to determine which technique is better suited to their needs. Ultimately, understanding the strengths and limitations of Renko and Range Bars will enable traders to make informed decisions and enhance their trading strategies.
