Building a Strong Foundation: How to Choose the Right Brick Size in Renko Charts

In the dynamic world of financial markets, traders seek tools that offer clarity and precision in deciphering price movements. Renko charts, known for their simplicity and effectiveness, provide a unique perspective on market trends. One crucial aspect that significantly influences the interpretative power of Renko charts is the choice of brick size. In this comprehensive guide, we will explore the importance of selecting the right brick size in Renko charts and provide practical examples to enhance your understanding.

I. Understanding Renko Charts

A. Brief Overview

Renko charts, originating from Japan, use bricks or blocks to represent price movements. Unlike traditional time-based charts, Renko charts focus on significant price changes, filtering out market noise. Each brick has a predetermined size, and the chart construction is solely based on price movements.

B. The Significance of Brick Size

The brick size in Renko charts determines the minimum price movement required to form a new brick. This pivotal factor influences the granularity of the chart and, subsequently, the signals it generates. Choosing the right brick size is akin to selecting the lens through which you view market trends.

II. Factors Influencing Brick Size Selection

A. Market Volatility

Highly volatile markets may necessitate smaller brick sizes to capture minor price fluctuations. Conversely, in less volatile markets, larger brick sizes can provide a clearer view of overall trends by filtering out noise.

B. Trading Style

Traders with a preference for shorter-term trades might opt for smaller brick sizes, enabling them to capitalize on more frequent, albeit smaller, price movements. Long-term traders may favor larger brick sizes to focus on broader trends.

C. Asset Class

Different assets exhibit varying levels of volatility. Currency pairs, for instance, can be more volatile than certain stocks. Traders should consider the unique characteristics of the asset they are trading when selecting an appropriate brick size.

III. Practical Examples

A. Small Brick Size Example: Intraday Forex Trading

Suppose a trader is engaged in intraday Forex trading and selects a small brick size of 10 pips. In this scenario, each brick represents a 10-pip price movement. This allows the trader to capture quick, short-term trends in the highly dynamic Forex market.


  • Brick Size: 10 pips
  • Buy Trade: Three consecutive bullish bricks indicating an uptrend.
  • Sell Trade: Two consecutive bearish bricks signaling a potential reversal.

B. Medium Brick Size Example: Swing Trading Stocks

For a swing trader focusing on stocks, a medium brick size of 0.5% of the stock price may be suitable. This size strikes a balance between capturing meaningful price movements and avoiding excessive noise.


  • Brick Size: 0.5% of stock price
  • Buy Trade: Four consecutive bullish bricks during an upward trend.
  • Sell Trade: Three consecutive bearish bricks, prompting consideration of an exit.

C. Large Brick Size Example: Long-Term Cryptocurrency Investing

In the realm of cryptocurrency, a long-term investor might opt for a larger brick size, such as a $100 price movement. This provides a broader perspective, helping the investor stay focused on the overarching trend.


  • Brick Size: $100
  • Buy Signal: Five consecutive bullish bricks over an extended period.
  • No Sell Signal: Absence of bearish bricks indicates the trend remains intact.

IV. Strategies for Experimentation

A. Backtesting

Before applying a specific brick size in live trading, backtesting is essential. Historical data can reveal how well a chosen brick size would have performed under various market conditions, helping traders refine their strategies.

B. Periodic Review

Market conditions change, and what works well with a certain brick size today may need adjustment tomorrow. Regularly reviewing and adjusting the brick size ensures alignment with current market dynamics.

V. Conclusion

In conclusion, building a strong foundation in Renko chart analysis involves a nuanced understanding of selecting the right brick size. Traders must consider market volatility, trading style, and the specific characteristics of the asset class they are trading. Practical examples illustrate how different brick sizes can be applied in various trading scenarios, empowering traders to make informed decisions.

Remember, the art of choosing the right brick size is a dynamic process. It requires ongoing experimentation, backtesting, and a keen awareness of market conditions. By mastering the art of selecting the optimal brick size, traders can unlock the full potential of Renko charts as a powerful tool for trend analysis and decision-making.
