Renko charting

1. Renko Charting: A Beginner’s Guide

Renko charts are a unique type of financial chart that filters out minor price fluctuations and focuses on significant price movements. Unlike traditional candlestick or line charts which plot price based on time, Renko charts plot price based on a specified price change. This results in a chart that can be easier to interpret and can help traders identify trends more clearly. This article will provide a detailed beginner's guide to Renko charting, covering its history, construction, advantages, disadvantages, settings, and how to use it in your trading strategy.

History and Origins

The origins of Renko charts can be traced back to Japan, where they were traditionally used for trading commodities, particularly rice. The name "Renko" itself comes from a Japanese word meaning "brick." This is because the charts visually resemble stacks of bricks. While their precise historical development is somewhat murky, they were used for decades by Japanese traders before becoming popular in Western markets in the 1990s. They were initially favored by floor traders who needed a quick visual method to assess trends amidst the noise of rapid price changes. The initial use case focused on identifying key support and resistance levels.

How Renko Charts are Constructed

The fundamental difference between Renko charts and traditional charts lies in their construction. Traditional charts plot price changes over *time*. Renko charts plot price changes over a specified *price movement*. Here's a step-by-step explanation:

1. **Brick Size:** The first and most crucial element is determining the "brick size." This represents the minimum price movement required to form a new brick. For example, if you set the brick size to $1, a new brick will only be formed when the price moves up or down by $1. This is a critical parameter, discussed in more detail later.

2. **Initial Brick:** The first brick is formed at the starting price of the asset.

3. **Price Movement and Brick Formation:** As the price moves, no new brick is formed until the price has moved by at least the brick size.

4. **Directional Bricks:**

  * **White/Green Bricks (or Up Bricks):**  These are formed when the price moves *up* by an amount equal to or greater than the brick size. The new brick is placed directly above the previous brick.
  * **Red/Black Bricks (or Down Bricks):** These are formed when the price moves *down* by an amount equal to or greater than the brick size. The new brick is placed directly below the previous brick.

5. **Ignoring Time:** Critically, Renko charts completely ignore the time dimension. Bricks are formed *only* when the price moves by the specified amount, regardless of how long it takes. This is what differentiates them from time-based charts.

6. **Brick Completion:** A brick is considered "complete" when a new brick of the opposite color is formed.

Advantages of Renko Charting

Renko charts offer several advantages over traditional charting methods:

• **Noise Reduction:** The most significant advantage is their ability to filter out minor price fluctuations (market noise). This makes it easier to identify the underlying trend. This is particularly useful in volatile markets. Related to this is the concept of Volatility, which Renko charts actively minimize in their visual representation.
• **Clearer Trend Identification:** By focusing on significant price movements, Renko charts provide a clearer visual representation of trends. Uptrends are easily identifiable as a series of consecutive white/green bricks, and downtrends as a series of consecutive red/black bricks. Understanding Trend Following strategies is crucial when using Renko charts.
• **Simplified Chart Analysis:** The simplified nature of Renko charts makes them easier to interpret, especially for beginner traders. The focus on price movement rather than time reduces complexity.
• **Automatic Support and Resistance:** The high points of uptrends and the low points of downtrends on a Renko chart often act as automatic support and resistance levels. Identifying Support and Resistance is a fundamental aspect of technical analysis.
• **Reduced False Signals:** The filtering of noise can help reduce the number of false signals generated by other technical indicators.
• **Focus on Price Action:** Renko charts emphasize pure price action, stripping away the complexities of time and volume. This allows traders to focus solely on price movements. This concept is strongly linked to Price Action Trading.

Disadvantages of Renko Charting

Despite their advantages, Renko charts also have some drawbacks:

• **Lagging Indicator:** Because Renko charts filter out noise, they inherently lag behind price movements. This means that signals generated by Renko charts may be delayed compared to signals generated by traditional charts.
• **Gaping:** Renko charts can exhibit gaps between bricks, which may not accurately reflect the actual price movement. This can be problematic for certain trading strategies. Understanding Candlestick Patterns can help contextualize these gaps.
• **Brick Size Sensitivity:** The choice of brick size is critical. A brick size that is too small will result in a chart that is still noisy, while a brick size that is too large will filter out too much information and potentially miss important price movements. Finding the optimal brick size requires experimentation and is dependent on the asset being traded and the trader's timeframe.
• **Loss of Time Information:** The complete disregard for time can be a disadvantage for traders who rely on time-based analysis, such as those using day trading strategies. Considering Time Series Analysis alongside Renko charts can be beneficial.
• **Difficulty in Backtesting:** Backtesting Renko chart strategies can be more challenging than backtesting strategies based on traditional charts due to the unique way Renko charts are constructed.
• **Limited Information:** Renko charts provide less information than traditional charts. They do not show the full range of price movements within a given period.

Choosing the Right Brick Size

Selecting the appropriate brick size is arguably the most important aspect of using Renko charts. There's no one-size-fits-all answer, as the optimal brick size depends on several factors:

• **Asset Volatility:** More volatile assets require larger brick sizes to filter out noise effectively. Less volatile assets can use smaller brick sizes. Consider the asset's Average True Range (ATR).
• **Timeframe:** Longer-term traders typically use larger brick sizes than shorter-term traders.
• **Trading Style:** Swing traders might prefer larger brick sizes to focus on major trends, while scalpers might prefer smaller brick sizes to capture smaller price movements.
• **Backtesting:** The best way to determine the optimal brick size is through backtesting different values on historical data. Focus on finding a brick size that generates profitable signals without excessive lag.
• **Percentage-Based Brick Size:** Some traders prefer to use a percentage-based brick size, such as 1% or 2% of the asset's current price. This allows the brick size to adjust automatically as the price changes.

• • General Guidelines:**

• **Stocks:** Start with a brick size of $0.50 to $2.00.
• **Forex:** Start with a brick size of 5 to 20 pips.
• **Commodities:** Start with a brick size of $0.10 to $1.00 per unit.
• **Cryptocurrencies:** Start with a brick size of $50 to $200 (depending on the cryptocurrency's price).

Using Renko Charts in Trading Strategies

Renko charts can be integrated into various trading strategies:

• **Trend Following:** Identify uptrends by looking for a series of consecutive white/green bricks and downtrends by looking for a series of consecutive red/black bricks. Enter long positions during uptrends and short positions during downtrends. Combine with moving averages like the Simple Moving Average or Exponential Moving Average for confirmation.
• **Breakout Trading:** Look for breakouts above resistance levels (identified by the highs of previous uptrends) or below support levels (identified by the lows of previous downtrends). Enter trades in the direction of the breakout.
• **Double Top/Bottom:** Identify double top formations (two consecutive highs) or double bottom formations (two consecutive lows) on the Renko chart. These patterns can signal potential trend reversals. Understanding Chart Patterns is essential for this strategy.
• **Renko with Indicators:** Combine Renko charts with other technical indicators, such as the Relative Strength Index (RSI), Moving Average Convergence Divergence (MACD), or Stochastic Oscillator, to confirm signals and improve accuracy.
• **Renko with Fibonacci Retracements:** Use Fibonacci retracement levels drawn on the Renko chart to identify potential support and resistance levels and entry/exit points.
• **Renko and Volume Analysis:** While Renko charts themselves don't display volume, incorporating volume analysis from the underlying chart can provide valuable confirmation of trends and breakouts. Analyzing Volume Spread Analysis can be particularly helpful.

Renko Chart Variations

While the standard Renko chart is the most common, several variations exist:

• **Variable Renko:** This type of Renko chart adjusts the brick size dynamically based on market volatility. For example, the brick size might increase during periods of high volatility and decrease during periods of low volatility.
• **Point and Figure (P&F):** While not strictly a Renko chart, P&F charts are similar in that they filter out noise and focus on significant price movements. Point and Figure Charting is a related technique worth exploring.
• **Equilibrium Renko:** This variation focuses on identifying equilibrium points in the market, where buying and selling pressure are balanced.
