Technical analysis plays a vital role in the options trading world, equipping investors with tools to identify potential entry and exit points for their positions. While traditional chart patterns like moving averages and Bollinger Bands are widely used, some lesser-known indicators can offer valuable insights. This blog delves into the world of Renko charts, exploring their unique characteristics, options trading strategies, and potential benefits for active traders.

What is a Renko chart?

Unlike traditional time-based charts, which plot price movements over time intervals (minutes, hours, days), Renko charts focus on price action itself. Developed by Japanese rice trader Hidenmu Yamamura in the early 1700s, Renko charts use "bricks" to represent price movements. A new brick is added to the chart only when the price moves by a predetermined amount, called a "box size." The direction of the brick (up or down) is determined solely by the direction of the price movement within that box size.

Key characteristics of Renko charts

  • Focus on Price Action: Renko charts prioritise price movements over time, potentially offering a clearer view of significant price trends and reversals.
  • Reduced Noise: Since new data points are added only when the price moves by a specific amount, Renko charts filter out minor price fluctuations, potentially leading to a less cluttered and smoother visual representation.
  • Simplicity: Renko charts are visually simple, potentially making them easier to interpret for some traders compared to traditional time-based charts with numerous data points.

Types of Renko charts

There are two primary variations of Renko charts:

  • Classic Renko: In classic Renko charts, each brick represents a fixed price movement. For example, a Renko chart with a 5-point box size will only add a new brick when the price moves up or down by 5 points.
  • Heiken Ashi Renko: This variation combines elements of Renko charts with the Heiken Ashi candlestick charting technique. The opening, closing, high, and low points of each Renko brick are calculated based on a formula similar to Heikin Ashi candlesticks, potentially offering additional insights into price trends.

Trading strategies with Renko charts

Traders can utilise Renko charts in conjunction with other technical indicators to develop trading strategies. Here are a few common approaches:

  • Trend Following: Since Renko charts can highlight strong price trends by filtering out minor fluctuations, they can be useful for identifying potential breakout opportunities or trend continuation plays. Traders can look for patterns like consecutive bricks moving in the same direction to confirm a trend.
  • Support and Resistance: Renko charts can help visualise potential support and resistance levels. Areas where the price struggles to break through a series of bricks in one direction might indicate zones of support or resistance.
  • Price Reversals: Changes in brick colour (upward to downward or vice versa) can signal potential trend reversals. This can be especially helpful when combined with other technical indicators that confirm a potential reversal.

Advantages and disadvantages of Renko charts


  • Focus on Price Movements: Renko charts prioritise price action, potentially offering a clearer view of significant trends and reversals.
  • Reduced Noise: By filtering out minor price fluctuations, Renko charts can be easier to interpret for some traders.
  • Potential for Early Signals: Due to their focus on price moves rather than time, Renko charts may sometimes provide earlier indications of trend changes.


  • Loss of Information: Filtering out minor price movements can also remove valuable information, potentially making it difficult to identify short-term trading opportunities.
  • Subjectivity in Box Size: The selection of the box size is subjective and can significantly impact the appearance and signals generated by the Renko chart. There's no "one size fits all" approach, and experimentation is needed to find the optimal box size for a particular trading strategy.
  • Limited Availability: Renko charting functionality might not be readily available on all trading platforms.


Renko charts offer a unique perspective on price movements, potentially aiding traders in identifying trends and making informed trading decisions. However, it's crucial to understand their limitations and use them in conjunction with other technical analysis tools for a more comprehensive market view. By incorporating Renko charts into their trading arsenal, active traders can potentially gain a valuable edge in navigating the ever-changing market dynamics.

Renko chart: advanced techniques

While the basic principles of Renko charts are straightforward, some advanced techniques can further enhance their utility for experienced traders:

  • Renko Chart Overlays: Renko charts can be overlaid on top of traditional time-based charts, allowing traders to compare price action using both perspectives. This can provide valuable insights into how price movements unfold over time in relation to the significant price swings captured by the Renko chart.
  • Volume Analysis with Renko Charts: While Renko charts themselves don't inherently depict trading volume, volume data can be incorporated into the analysis. For instance, traders can look for periods of high volume coinciding with significant Renko bar formations to confirm the strength of a trend or potential reversal.
  • Combining Renko with Other Indicators: Renko charts can be effectively combined with various technical indicators like moving averages, MACD, or RSI to generate more comprehensive trading signals. For example, a breakout above a resistance level on a Renko chart, combined with a bullish crossover on the MACD indicator, can strengthen the confirmation of a potential uptrend.

Who should use Renko charts for options trading?

Renko charts might be particularly suitable for traders who:

  • Prioritise Price Action: If a trader focuses primarily on identifying significant price movements and trends, Renko charts can potentially offer a clearer view by filtering out minor fluctuations.
  • Employ Trend-Following Strategies: Renko charts can excel at highlighting strong trends, making them a potentially valuable tool for trend-following traders.
  • Seek to Simplify Chart Analysis: For some traders, the visual simplicity of Renko charts can be easier to interpret compared to time-based charts with numerous data points.

Final note

The world of technical analysis offers a vast array of tools and indicators. While Renko charts might not be for everyone, understanding their unique characteristics and potential benefits can empower traders to make informed decisions about incorporating them into their trading strategies. Remember, successful trading involves a combination of technical analysis, sound risk management, and a deep understanding of market psychology.
