Renko Charts

In essence, Renko charts are plotted as a series of bricks representing price movement and completely ignoring the time factor. A brick will only be printed when the price has made a specified amount of movement, no matter the time required to achieve that. 

Naturally, the bigger the brick size, the lesser movement a Renko chart will display. But on the flip side, a very small brick size will erode the meaning of a Renko chart.

Construction of Renko Charts

Renko bars or bricks are constructed using only closing prices and are placed at 45-degree angles next to each other. While they have a time axis, it is only meant to be considered if the set movement (closing prices) has been realized and not to show elapsed time. Bullish bricks form above the previous bricks, whereas bearish bricks form below the last bricks. 

Renko bricks are never drawn next to each other. For an opposite brick to be printed next to the other, the asset price must move at least twice the set movement. For instance, if a brick size is 50 pips, for a Renko chart to show a transition from a bullish brick to a bearish brick, the price must close lower by at least 100 pips. 

Brick Sizing Techniques

Choosing the right brick size is one of the most important decisions when using Renko charts.

Brick size directly impacts how much price noise is filtered out, how often new bricks form, and how reliable the trading signals appear. There are three main approaches:

1. Fixed Brick Size

In this method, each brick represents a set price movement (e.g., $5, £10, or 50 pips). A new brick forms only when the price moves by at least that amount from the last brick’s closing price.

• Advantages: Simple to understand and consistent across different market conditions.
• Drawbacks: May be too rigid in volatile markets, leading to delayed signals.

Example: On EUR/USD, a fixed size of 50 pips may capture major swings while ignoring smaller fluctuations.

2. ATR-Based Brick Size

Here, the brick size is set according to the Average True Range (ATR), which measures market volatility over a specified period.

• Advantages: Automatically adjusts to changing volatility, making charts more responsive during fast-moving markets and less noisy during quiet periods.
• Drawbacks: May require recalculating periodically to stay aligned with market behaviour.

Example: If the ATR over the last 14 periods is 0.0080 (80 pips), this value becomes the brick size, dynamically adapting to volatility.

3. Percentage-Based Brick Size

This method uses a fixed percentage of the asset’s price to determine brick size.

• Advantages: Keeps brick size proportional to the price level, useful for long-term charts across multiple instruments.
• Drawbacks: Less common in day trading, as percentage changes can be too large or too small for short-term moves.

Example: A 1% brick size on a stock priced at £200 means each brick equals £2.

Market Suitability for Renko Charts

Renko charts are highly effective at filtering out market noise and highlighting trends, but their value can vary depending on the instrument and trading style.

Understanding where Renko works best helps traders focus their efforts for better results.

1. Trending Forex Pairs

Renko charts are particularly popular in forex trading, where identifying and following trends is key.

• Best suited pairs: EUR/USD, GBP/USD, USD/JPY — known for sustained moves.
• Why it works: By ignoring time and focusing only on price movement, Renko removes much of the “whipsaw” effect found in choppy intraday charts.

Tip: Use smaller brick sizes for short-term forex trades and larger sizes for position trading.

2. Commodities and Indices

Instruments like gold, oil, and indices such as the S&P 500 or FTSE 100 often develop strong, sustained moves that Renko charts capture clearly.

• Strength: Renko can highlight long-term directional bias without distraction from intraday volatility.
• Caution: Commodity prices can react sharply to news, so pairing Renko with fundamental awareness is crucial.

3. Stock Trading

For equities, Renko charts can help spot breakouts and reversals in trending stocks.

• Strength: Reduces the noise caused by short-term market fluctuations, especially during earnings season.
• Caution: Stocks with low liquidity or irregular price movements may produce unreliable Renko patterns.

4. Cryptocurrency

Given their extreme volatility, cryptocurrencies can produce Renko charts with very clear trend signals.

• Strength: Smooths out noise while retaining visibility of large price swings.
• Caution: Brick size choice is critical — too small and the chart becomes overly reactive; too large and key reversals may be missed.

Timeframe vs. Brick Size

While Renko charts are not time-based, the timeframe you select for your data feed still influences the outcome.

Combined with your chosen brick size, it determines how quickly new bricks form and how reactive the chart is to price changes.

1. Shorter Timeframes – Faster Signals

When using data from lower timeframes (e.g., 1-minute or 5-minute charts), bricks can form quickly, especially with smaller brick sizes.

• Best for: Scalping or short-term day trading.
• Advantage: Early entries into fast-moving trends.
• Drawback: Higher risk of false signals, especially in sideways markets.

Tip: If scalping, consider combining small brick sizes with a momentum indicator like RSI to avoid overtrading.

2. Medium Timeframes – Balanced Approach

Using data from 15-minute to 1-hour charts provides a balance between responsiveness and noise reduction.

• Best for: Swing traders looking to hold positions for several hours or days.
• Advantage: Clearer trend identification with fewer false signals compared to short timeframes.

3. Higher Timeframes – Strong Trend Focus

Daily or weekly data feeds with larger brick sizes create Renko charts that move slowly but filter out almost all short-term volatility.

• Best for: Position traders and long-term investors.
• Advantage: Focuses entirely on major price shifts, ignoring intraday fluctuations.
• Drawback: Signals are fewer and slower to form, which may miss shorter-term opportunities.

4. Matching Brick Size to Timeframe

• Small brick sizes + short timeframe: High sensitivity, ideal for fast trades but prone to noise.
• Large brick sizes + long timeframe: Strong trend focus, best for patient traders.
• Medium brick sizes: Versatile for multiple trading styles.

Trading with Renko Charts – Renko Trading Strategy

A Renko forex strategy may help traders identify quality trading opportunities. Here are some of the signals delivered by a Renko chart:

Renko Support and Resistance Levels

Renko charts show strong support and resistance levels when the bricks alternate at a certain price area for some time. At these levels, traders can trade range-bound strategies and watch out for potential price breakouts. A range-bound play will involve buying near support areas and selling near resistance. Because Renko charts highlight strong support and resistance areas, traders can watch out for price breakouts and ride the new trend. 

Renko Chart Patterns

As Renko bricks are drawn over time, they also form chart patterns that can be found in typical candlestick charts, such as double tops and double bottoms, head and shoulders, and triangles. When such chart patterns form on a Renko chart, they are easy to spot and are more reliable and have high probability opportunities.

Trailing Stops

Renko charts make it easy for traders to identify the long-term dominant trend. This could be an opportunity for traders to ride the trend for long-term profits. While this is great, it is also essential to book partial profits as the trend runs along. Renko charts are ideal for identifying the optimal price areas where trailing stops can be placed to maximize the profits of following an existing trend. 

Renko charts deliver quality and reliable signals to traders. However, the formation of boxes can sometimes be prolonged; and this can deny traders the chance of exploiting a good opportunity early on. While long-term traders will not mind this, it could be very limiting for short-term trading strategies such as scalping. 

Trading Setups & Signal Confirmation

Renko charts excel at filtering out noise and making trends easier to spot, but the real power comes from combining them with structured setups and confirmation tools.

Below are practical ways traders use Renko charts to generate and validate trading opportunities.

1. Breakout Trades

Renko charts can make breakouts more obvious by removing false wicks and intraday noise.

• Setup: Identify a horizontal resistance or support level. When a new Renko brick closes beyond this level, it may signal a breakout.
• Confirmation: Combine with an increase in volume or a momentum indicator such as the RSI breaking above 50 for bullish moves.

Tip: Wait for one or two bricks to form beyond the breakout level to avoid “false breaks.”

2. Trend-Following Entries

Renko charts simplify the identification of sustained trends.

• Setup: Use a moving average (e.g., 50-period SMA) on your Renko chart to define the trend direction.
• Entry rule: Go long when bricks are above the moving average and aligned in the trend direction; short when below.
• Exit rule: Close when bricks reverse colour and cross back through the moving average.

3. Reversal Spotting

The colour change in Renko bricks can signal potential reversals earlier than some time-based charts.

• Setup: Watch for divergence between Renko price action and an oscillator like MACD or RSI.
• Confirmation: Look for a brick colour change accompanied by the oscillator crossing a key threshold (e.g., RSI moving above 30 from oversold).

4. Multi-Timeframe Confirmation

Using multiple Renko charts with different brick sizes helps avoid premature entries.

• Setup: Identify the main trend on a chart with a larger brick size. Use a smaller brick size chart to fine-tune entry and exit points.

Limitations & Pitfalls of Renko Charts

While Renko charts can be powerful for trend identification and noise reduction, they are not without drawbacks.

Being aware of these limitations — and knowing how to manage them — is essential for long-term trading success.

1. Delayed Signal Formation

Renko charts only update when the price moves enough to form a new brick. This means you may enter later than you would with a time-based chart.

Mitigation: Combine Renko with faster-reacting indicators like short-term moving averages to catch early momentum shifts.

2. Inappropriate Brick Sizing

Using brick sizes that are too small can create excessive noise, while brick sizes that are too large can hide important reversals.

Mitigation: Backtest different sizes on your chosen asset to find a balance between responsiveness and clarity. ATR-based brick sizing can also help adapt to changing volatility.

3. Lack of Volume Context

Renko charts don’t display volume by default, which can make it harder to confirm the strength behind a price move.

Mitigation: Add a volume indicator or On-Balance Volume (OBV) to your chart for extra confirmation.

4. Vulnerability in Low-Volatility Markets

When price moves slowly or in narrow ranges, Renko charts can remain unchanged for long periods, providing little actionable information.

Mitigation: Be prepared to switch to time-based charts during low-volatility phases to identify potential breakouts.

5. Over-Reliance Without Context

Renko charts are a tool, not a complete trading system. Relying on them alone without considering news events, fundamental analysis, or broader market sentiment can lead to poor decisions.

Mitigation: Integrate Renko analysis into a broader strategy that includes multiple forms of confirmation.
