Renko Chart Basics: A Beginner’s Guide to Reading & Trading

Renko Chart Basics: How Renko Charts Work

Renko chart basics become much easier once you understand one key idea: Renko charts focus primarily on price movement rather than time.

Instead of creating a new candle every minute, hour, or day, a Renko chart builds bricks when price moves far enough to satisfy the chart’s brick-size rules.

The result is a chart that can make trends, reversals, support, and resistance easier to see because many smaller price fluctuations are filtered from the visual structure.

In this beginner guide, I’ll explain how Renko bricks form, how Renko differs from candlestick charts, how to choose a starting brick size, how to set up Renko in TradingView, and some common mistakes to avoid.

If you eventually want to move beyond the basics, my complete Renko charts guide organizes brick sizing, entries, exits, risk management, and backtesting into a larger learning path.

What Is a Renko Chart?

A Renko chart is a price chart built from a series of rectangular blocks called bricks. The name Renko is generally associated with the Japanese word renga, meaning brick.

Unlike a candlestick chart, Renko does not create a new chart element simply because another fixed period of time has passed.

Instead, price has to move far enough to satisfy the Renko chart’s brick-building requirement.

For example, imagine you’re using a hypothetical fixed brick size of $2.

• Price moves far enough upward to complete the next bullish brick.
• Another sufficient upward move creates another bullish brick.
• If price fluctuates without satisfying the next brick requirement, no new completed brick appears.
• A sufficiently large move in the opposite direction can eventually create a reversal brick.

The exact construction rules can vary by charting platform and Renko settings, particularly when reversals, wicks, ATR sizing, and underlying data are involved. That’s why I think it’s more useful for beginners to understand the concept before memorizing a single formula.

How Renko Bricks Form

Think of brick size as the Renko chart’s price filter.

If your brick size is small, the chart responds to smaller price movements. If your brick size is large, price has to travel farther before another brick can be completed.

Setting	Typical Effect
Smaller brick size	More bricks, more sensitivity, more potential reversals
Larger brick size	Fewer bricks, more filtering, broader trend structure

This is one reason Renko charts can look cleaner than candlestick charts. Price movement that isn’t large enough to complete another brick may disappear from the main visual structure.

But filtering price movement comes with a tradeoff. A smoother chart can also mean waiting longer for confirmation.

Renko vs Candlestick Charts

Renko and candlestick charts show the same market from different perspectives.

A candlestick chart organizes price activity into fixed periods of time. Renko reorganizes price movement into bricks based on a selected brick-building method.

Renko Charts	Candlestick Charts
Focus on price movement	Focus on price movement within fixed time periods
Filter smaller price fluctuations	Display each selected time interval
Can make trends easier to visualize	Preserve more time-specific price information
Brick size strongly affects chart appearance	Timeframe strongly affects chart appearance
Useful for studying trend structure	Useful for studying opens, closes, highs, lows, wicks, and time-specific behavior

I don’t think you have to choose one chart type permanently.

You might use candlesticks when time, wicks, or detailed intrabar structure matter to your analysis, while using Renko to study broader trend direction and filter smaller price movements.

For actual entry and exit examples, see my Renko chart buy and sell signals guide.

How to Read a Renko Chart

Once your brick size is established, reading the basic chart structure is relatively straightforward.

Bullish Renko Trend

A sequence of rising bullish bricks indicates that price is moving upward by enough to continue satisfying the Renko brick requirement.

Bearish Renko Trend

A sequence of falling bearish bricks indicates that price is moving downward by enough to continue producing bricks in that direction.

Renko Reversal

A change in brick direction tells you that price has moved far enough in the opposite direction to satisfy the chart’s reversal requirement.

A reversal brick by itself does not necessarily mean a major market trend has changed. Short reversals can occur inside larger trends, which is why many Renko strategies use additional confirmation.

Support and Resistance

Because Renko removes some smaller fluctuations, repeated brick highs and lows can make potential support and resistance areas visually easier to identify.

I still treat these as areas to analyze rather than guaranteed turning points.

Choosing a Renko Brick Size

Brick size is one of the most important Renko settings because it determines how much price movement the chart filters.

There isn’t one ideal brick size for every stock, ETF, forex pair, cryptocurrency, timeframe, or strategy.

For beginners, I would focus on understanding two basic methods.

Fixed-Size Renko Bricks

With a fixed-size approach, you choose a specific price amount for the brick parameter.

For example, you might experimentally test $1, $2, and $3 fixed brick values on a stock and compare how each setting changes the chart.

I like fixed sizing for controlled experiments because the parameter remains easy to understand and compare.

ATR-Based Renko Bricks

ATR uses Average True Range as a volatility measurement. Depending on the platform and method you’re using, ATR can either be used directly in the Renko calculation or help you estimate a reasonable fixed brick size to test.

This distinction matters. A native ATR-based Renko setting can behave differently from calculating ATR yourself and then entering the resulting number as a fixed brick size.

For the full explanation, see my ATR-based Renko brick size guide.

You can also use my free Renko Brick Size Calculator to generate starting values for your own experiments.

Once you understand brick size, the next settings to learn are timeframe, wicks, and reversal confirmation. I cover those together in my best Renko chart settings for TradingView.

How to Set Up a Renko Chart in TradingView

TradingView makes it relatively easy to experiment with Renko charts.

1. Open a chart. Choose the stock, ETF, forex pair, cryptocurrency, or other market you want to study.
2. Open the chart-type menu. Select Renko from the available chart types.
3. Open the Renko settings. Review the available brick calculation method.
4. Choose your brick method. Depending on your setup, this may include Traditional/fixed sizing or ATR.
5. Enter or select the brick-size setting. Start with a reasonable experimental value rather than trying to find a perfect setting immediately.
6. Decide whether to display wicks. Wicks can provide additional information about price movement beyond completed brick bodies.
7. Study the basic chart first. Before adding several indicators, make sure you can identify trends, reversals, and consolidation using the bricks themselves.

The exact options available can change with the charting platform, so I focus more on understanding what each setting does than memorizing where every button is located.

Should Beginners Add Indicators to Renko?

You can use indicators with Renko, but I wouldn’t begin by covering the chart with them.

Start by learning the brick structure. Once that makes sense, adding one confirmation tool can help you experiment with entries and reversals.

Common examples include:

• moving averages
• Supertrend
• RSI
• MACD
• trendlines
• support and resistance

The indicator should answer a specific question. Adding five indicators that all measure similar things usually doesn’t make the underlying Renko structure easier to understand.

A Simple Renko Workflow for Beginners

If you’re opening Renko for the first time, I would keep the process simple.

1. Choose one market. Don’t jump between ten different symbols while you’re learning.
2. Choose a starting brick size. Use either a fixed value or an ATR-based method you understand.
3. Study the brick structure. Identify bullish trends, bearish trends, reversals, and sideways periods.
4. Add one confirmation tool if needed. For example, test a moving average or Supertrend.
5. Define an entry rule. Decide exactly what has to happen before you would consider entering.
6. Define an exit rule. Decide what invalidates the trade or signals that the trend may be ending.
7. Backtest the rules. See how they behaved across different historical conditions.
8. Practice before risking money. Use historical testing or simulated trading to understand the setup first.

This approach helps separate learning Renko from trying to build a complicated trading system on day one.

Renko Example: Combining Trend and Confirmation

Once the basic chart makes sense, you can begin testing simple combinations.

One example is combining Renko bricks with Supertrend. The Renko structure filters smaller price movements while Supertrend provides another way to evaluate trend direction.

The important point isn’t that Supertrend is a required Renko indicator. It’s an example of how you can begin with the Renko trend and then test whether a second rule improves your decision process.

Do Renko Charts Have a Timeframe?

This is one of the most confusing Renko concepts for beginners.

Renko bricks are primarily driven by price movement, but that does not mean timeframe is completely irrelevant.

Charting platforms use underlying price data to construct the Renko chart. The resolution of that source data can influence the resulting historical bricks.

So I think about the two settings separately:

Setting	What It Controls
Brick size	How much price movement the Renko chart represents
Underlying timeframe	The resolution of the source price data used to construct the chart

For a complete explanation with starting ranges for day trading, swing trading, and longer-term analysis, see my best timeframe for Renko charts guide.

Common Renko Mistakes Beginners Make

1. Choosing Bricks That Are Too Small

Very small bricks can create a large number of reversals and signals. If your Renko chart looks excessively active, examine the brick size before adding more indicators.

2. Choosing Bricks That Are Too Large

Larger bricks filter more movement, but excessive filtering can make entries and reversals appear much later than your strategy needs.

3. Looking for a Perfect Brick Size

There isn’t a magic number that works for every market. I prefer testing a reasonable range and looking for settings that behave consistently rather than optimizing for one perfect historical result.

4. Adding Too Many Indicators

Renko is useful partly because it simplifies the visual structure. Covering the chart with indicators can quickly bring the complexity back.

5. Treating Every Reversal Brick as a Trade

A Renko reversal is information, not an automatic buy or sell signal. Your strategy still needs rules for confirmation, risk, and exits.

6. Assuming Renko Removes Risk

Renko can simplify how price movement is displayed. It cannot eliminate losing trades, false breakouts, gaps, execution differences, or changing market conditions.

7. Skipping Backtesting

A clean historical Renko chart can make a strategy look obvious after the fact. Backtesting forces you to define the rules and measure what actually happened under those assumptions.

My Renko backtesting guide walks through that process in TradingView.

Renko Chart Basics FAQ

What Is a Renko Chart?

A Renko chart is a price chart constructed from bricks rather than traditional time-based candles. New bricks are created when price satisfies the selected brick-size and construction rules, which can filter smaller price fluctuations from the chart.

Are Renko Charts Good for Beginners?

Renko can be useful for beginners because the chart can make basic trend structure easier to visualize. Beginners still need to understand brick size, reversals, risk management, and how their charting platform constructs Renko bricks.

What Is the Best Renko Brick Size?

There is no universal best brick size. The appropriate setting depends on the market, volatility, timeframe, and strategy. I prefer testing several reasonable values rather than assuming one setting will work everywhere.

What Timeframe Is Best for Renko Charts?

There is no single best Renko timeframe. Higher-resolution source data can make sense for short-term strategies, while slower source data may be suitable for swing or longer-term analysis. Brick size should be considered along with timeframe.

Can You Use Renko Charts for Day Trading?

Yes, Renko charts can be tested for day trading. Short-term traders often experiment with higher-resolution source data and smaller brick sizes, but the combination should be backtested because smaller bricks can also produce more reversals.

Can You Use Renko Charts for Swing Trading?

Yes. Renko can be useful for studying multi-session trends because larger brick sizes can filter some smaller price fluctuations. The appropriate settings depend on the market and holding period.

Do Renko Charts Show Time?

Renko does not use time to create evenly spaced candles the way traditional charts do. However, underlying timeframe and price-data resolution can still influence how a charting platform constructs the Renko bricks.

Are Renko Charts Better Than Candlesticks?

Neither chart type is universally better. Renko emphasizes filtered price movement and trend structure, while candlesticks preserve time-based opens, highs, lows, closes, and wicks. The better choice depends on what information your strategy needs.

Can I Backtest Renko Charts in TradingView?

Yes. TradingView can be used for Renko strategy experiments and backtesting, but Renko charts are synthetic. Historical brick construction and simulated order execution should therefore be interpreted carefully rather than treated as perfect reproductions of live trading.

Where to Go After Learning the Renko Basics

Once you’re comfortable reading basic Renko bricks, I would learn the next pieces in this order:

1. Learn brick sizing so you understand how volatility and brick size interact.
2. Understand Renko timeframes and the role of underlying source data.
3. Study Renko buy and sell signals and turn chart structure into objective rules.
4. Define your exit rules instead of concentrating only on entries.
5. Backtest the complete idea before deciding whether the strategy deserves further testing.

Final Thoughts on Renko Chart Basics

If you’re just starting with Renko charts, don’t worry about finding the perfect strategy immediately.

First, learn what the bricks are telling you.

Understand how brick size changes the chart. Learn to recognize bullish and bearish sequences, reversals, and periods when price isn’t moving cleanly in either direction. Then begin adding simple rules and testing them.

That’s where I think Renko is most useful: turning complicated price movement into a simpler structure that you can analyze with consistent rules.

Renko doesn’t predict the future and a cleaner chart doesn’t eliminate trading risk. But used carefully, it can provide a different and often clearer way to study trends and price structure.
