What Is Renko chart and how does it work?

Renko chart

A Renko chart is a type of chart used in financial trading that represents price changes in a different way compared to more traditional charts like candlestick or bar charts. Here's how it works in simple terms:

Bricks: Renko charts are made up of "bricks" that represent price movement. Each brick is the same size and shows a fixed amount of price change. The size of each brick is called the "box size" and can be adjusted according to your preference or trading strategy.
Price Movement: A new brick is added to the chart when the price moves a certain amount (equal to the box size) from the previous brick's closing price. For example, if the box size is set to 10 points and the price goes up or down by 10 points, a new brick will be added.
Direction: Bricks are added in columns, either up or down. If the price increases by the box size, a new brick is added above the previous one. If the price decreases by the box size, a new brick is added below the previous one.
No Time Factor: Unlike other charts that consider time intervals (such as minutes, hours, or days), Renko charts focus only on price movement. This means a Renko chart can appear to move slowly during times of low volatility or rapidly during high volatility.
Smoothing Out Noise: Renko charts are great for filtering out market noise and focusing on significant price movements. They provide a clear visual of the market's trends and can help identify support and resistance levels.
Visual Trends: Because of the way Renko charts represent data, they make it easy to see trends and changes in market direction. This can be helpful for traders who want to identify strong trends without being distracted by short-term fluctuations.

Nifty 50 index chart ( Traditional chart)

This traditional Nifty chart makes it harder to detect support and resistance levels compared to Renko charts. Price movements appear choppy and unclear, which can make identifying trends and reversals challenging. This can lead to difficulties in making trading decisions based on visual cues.

On the other hand this Nifty index chart shows clear trends and support/resistance levels when compared to above traditional charts for the same period, Renko charts help identify price reversals and make it easier to spot trends and changes in direction.

Renko chart settings

Renko charts help traders identify trends, support, and resistance levels more clearly than traditional price charts. Key settings for Renko charts include:

Brick Size: This is the fixed price movement needed to create a new brick (or block) on the chart. Choose a brick size based on a fixed value (e.g., 10 points) or a percentage of the current price (e.g., 1%). Larger brick sizes smooth out noise and focus on longer trends, while smaller sizes capture more details.
Calculation Method: Typically, closing prices are used to determine when a new brick is added, but other methods like high/low prices are options.
Time Frame: Renko charts can be used with any time frame (e.g., daily, weekly), but the chosen time frame can influence perceived trends.
Reversal Setting: This controls how many bricks must reverse direction to confirm a trend reversal, often set to one brick.

How to install a Renko chart

Renko charts can offer traders a clear view of trends, helping to identify support and resistance levels. Most modern trading platforms provide built-in functionality to create Renko charts. In some cases, though, additional actions may be required, such as downloading specific charting plugins or indicators. To install a Renko chart, you should first check your trading platform's charting tools to see if Renko is an available option. If it is, you can simply choose it and adjust the settings according to your preferences. If not, you might need to download an external Renko chart plugin or indicator and follow the installation instructions provided by the developer.

Strategies for trading with Renko charts

Renko charts are a valuable tool for traders seeking a clear visual representation of price movements. Unlike traditional charts, Renko charts focus on significant price changes rather than time-based fluctuations. This makes them useful for identifying trends and potential trading opportunities. Experts have discussed below some strategies for trading with Renko charts.

Follow the trend

Renko charts excel at highlighting trends. One effective strategy is to enter trades in the direction of the prevailing trend.
For long trades, wait for Renko bricks to turn from red to green (indicating an upward trend). Enter a trade once the trend is confirmed, typically after a few green bricks.
For short trades, wait for Renko bricks to turn from green to red (indicating a downward trend). Enter a trade once the trend is confirmed, typically after a few red bricks.

Support and resistance breakouts

Look for Renko bricks to break through established support or resistance levels.
When this happens, it can signal a potential trade opportunity in the direction of the breakout.

Determining stop loss on Renko chart

Below/Above the Previous Brick:

For long trades, set a stop loss below the previous red brick.
For short trades, set a stop loss above the previous green brick.

ATR-based Stop Loss:

Some traders use the Average True Range (ATR) to determine their stop loss levels.
Multiply the ATR value by a factor (such as 1 or 1.5) and use that to set your stop loss above/below the most recent Renko brick.
This can help account for volatility and provide a more dynamic stop loss level.

Renko charts are unique in their simplicity and ability to filter out market noise, making them ideal for identifying clear price trends and reversal patterns. There are several patterns to watch for when using Renko charts:

Trend Continuation

In an uptrend, a series of consecutive green bricks indicates a strong upward movement.
In a downtrend, a series of consecutive red bricks signifies a strong downward movement.

Downtrend ( Trend continuation)

Reversal patterns

A reversal pattern occurs when the color of the bricks changes from green to red (or vice versa).
This pattern suggests a potential change in trend direction and can be an entry or exit point.

Reversal pattern (Renko charts)

Double brick reversal

A strong reversal is confirmed when there are two bricks in the opposite direction from the current trend.
For example, in an uptrend, if two consecutive red bricks form, it indicates a potential downward reversal.

Breakouts

When the price breaks through a key support or resistance level on the Renko chart, it can indicate a breakout.
This can be a signal to enter a trade in the direction of the breakout.

What is the best indicator to use with Renko chart for trading?

The best indicator to use with Renko charts for trading is subjective and depends on your trading style and objectives. However, a few popular indicators work well with Renko charts:

Moving Averages

Moving averages help smooth out price data and provide insight into the market's trend direction.
With Renko charts, using short-term and long-term moving averages can help identify entry and exit points when crossovers occur.

Relative Strength Index (RSI)

RSI is a momentum oscillator that measures the speed and change of price movements.
It changes with Renko charts because Renko charts filter out small price fluctuations, so RSI reflects clearer signals based on the underlying price action.

MACD (Moving Average Convergence Divergence)

MACD combines moving averages and measures the relationship between two exponential moving averages (EMA).
It can confirm trends identified on Renko charts and provide trade signals.

Parabolic SAR

Parabolic SAR helps identify potential reversals and can be effective with Renko charts to spot changes in market direction.
It works differently with Renko and Heikin Ashi charts due to the smoothing effects of these charts. Renko and Heikin Ashi charts filter price data differently, so the Parabolic SAR signals may vary depending on the chart type.

Can you backtest Renko?

Backtesting trading strategies on Renko charts can be tricky because the way Renko charts are constructed differs significantly from traditional candlestick charts. Here are the main problems that history testing on Renko charts can produce skewed results:

Time Insensitivity

Renko charts are based on price movements, not time intervals.
This can lead to misinterpretations, as the same historical price data may present different patterns on Renko and candlestick charts.

Data Availability

Reliable and detailed historical data for Renko charts can be hard to find, particularly from free sources.
Inaccurate or incomplete data can lead to skewed backtesting results.

Overfitting

Strategies that perform well on Renko charts may not perform as well on traditional candlestick charts due to the charts' different constructions.
Overfitting occurs when a strategy is too finely tuned to a particular dataset, resulting in poor performance in real-time trading.

SuperTrend Strategy Example

Supertrend strategy example

As shown in the example images, a simple SuperTrend strategy that appears profitable on Renko charts (above), may result in losses when applied to traditional candlestick charts (below).

Supertrend strategy example

This disparity can lead traders to believe they have a profitable strategy when, in reality, it may not work in other trading contexts.

Do professional traders use Renko charts?

Professional traders may use Renko charts as one of their tools in their trading strategy, but they're not a replacement for other methods of technical analysis. Renko charts offer a simplified view of price movement, which can help traders focus on the trend and reduce noise. Traders use Renko patterns like double tops and double bottoms to spot possible trend reversals, and consolidation zones to identify periods of sideways movement. Breakouts, where price pushes through support or resistance levels, are also key for traders. However, many professionals also rely on traditional candlestick charts or combine Renko charts with other chart types for a more comprehensive view of market conditions.

What are the advantages and disadvantages of the Renko chart?

Simplified chart view: Easier to understand price action and trends without noise.
Clear trend identification: Easy to spot long-term trends due to the chart's design.
Better support and resistance levels: Helps identify key levels where price may reverse.
Filters out market noise: Removes small, insignificant price fluctuations.
Provides clearer entry and exit points: Helps traders make decisions based on visual trends.
Works well with other indicators: Can be combined with traditional indicators like RSI and moving averages for a more comprehensive analysis.

Delays in showing trends: There can be a lag in updating the chart as it needs a significant price movement to form a new brick.
Lacks detailed price data: Omits minor price movements, potentially missing important intraday swings.
Not suitable for precise entries: Lacks the exact timing provided by traditional charts.
Limited real-time data: Not as effective for short-term trading decisions.
May require manual box size adjustments: Traders may need to fine-tune settings for specific assets or markets.
Less common in trading platforms: Not all platforms offer Renko chart functionality, limiting accessibility.

A few practical remarks

Renko blocks can take quite a long time to form, for example, several hours or days, until the price passes the necessary distance. Because of this, it is extremely difficult to see the beginning of a sideways trend and fix an open position in time. The situation is similar with the trend reversal: while the reversal block is formed, you can be in a serious loss.
The Renko chart does not take into account volumes and does not show the volatility of the instrument. Renko charts give many false signals in volatile markets, especially during flat periods.
The block size should be periodically adapted to the current volatility. A particular block size may be optimal for past data, but that does not make it suitable for future prices. Blocks that are too large will show trend changes with a lag, blocks that are too small will draw attention to minor price changes.
As a rule of thumb, the size of a Renko block should not exceed 1.5-2 ATR. If there is a significant difference with traditional trend indicators, it is better to adjust the block size.
The Renko chart is a calculated visual representation of price information and should be used only as an indicator of trend direction and strength. A reversal on Renko requires mandatory confirmation by additional indicators, both trend and momentum. It is not possible to determine the entry point from this chart.

Expert opinion

Renko charts can be a valuable tool for experienced traders who want a simplified view of market trends and movements. They can offer clearer visualizations of trends and support/resistance levels, which can aid in making trading decisions. However, due to their focus on larger price movements and lack of time-based data, Renko charts may not be the best option for traders seeking precision in entry and exit points. Integrating Renko charts with other indicators and traditional chart types can help traders make more informed decisions and improve overall strategy effectiveness.

Conclusion

Renko charts offer traders a distinct advantage by filtering out market noise and highlighting the most critical price movements. Unlike traditional candlestick or bar charts, Renko charts focus solely on price changes, allowing for clearer trend identification and more confident trading decisions. For instance, traders frequently use Renko charts to pinpoint support and resistance levels or to confirm trend reversals with greater accuracy. Embracing Renko charts as part of a broader technical analysis toolkit can empower traders to navigate volatile markets with greater clarity and conviction. Ultimately, those who master Renko chart interpretation can transform uncertainty into actionable insight, making smarter, more decisive trades.

FAQs

How does the choice of brick size affect trading signals on Renko charts?

The chosen brick size on a Renko chart determines how much price movement is required to form a new brick. Larger brick sizes filter out more minor fluctuations and highlight longer-term trends, but may lag in signaling reversals. Smaller brick sizes capture more detailed price action and can make the chart more sensitive, but also introduce additional noise. Selecting an appropriate brick size is crucial and should be periodically adjusted to match current market volatility.

Can Renko charts be combined with other technical indicators for enhanced analysis?

Yes, Renko charts are often used alongside other technical indicators such as moving averages, RSI, MACD, and Parabolic SAR. These combinations help provide confirmation of signals detected by Renko patterns and address their limitations, such as time insensitivity and lack of volume data. Blending Renko with additional tools offers a more comprehensive approach to trading decisions.

What types of market conditions are Renko charts best and least suited for?

Renko charts are best suited for trending markets where significant price movements occur, as they clearly display trends and reversals by filtering out minor fluctuations. They are less effective during flat or highly volatile markets, as they may generate false signals, lag trend changes, or fail to capture sudden price moves promptly due to their reliance on price movement thresholds rather than time.

Are there any risks in relying solely on Renko charts for trading decisions?

Relying exclusively on Renko charts carries risks because they do not consider time, volume, or volatility, and there can be delays in recognizing trend changes. This can lead to late entries or exits, especially in fast-moving or choppy markets. Renko should be supplemented with additional indicators or chart types to confirm trends and avoid misinterpreting signals.
