What Is Renko Chart? Complete Guide for Forex & CFD Traders 2026

Risk Warning: CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. Between 74–89% of retail investor accounts lose money when trading CFDs. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.

A Renko chart is a type of price chart that filters out time and minor price fluctuations, plotting only price moves that exceed a defined threshold called the brick size. Each “brick” (a rectangular block) is drawn only when price moves by the brick size amount in one direction. Upward bricks are typically drawn in white or green; downward bricks in black or red. A new brick can only be drawn in the opposite direction once price has moved at least two brick sizes in reverse. This reversal requirement eliminates minor counter-moves and creates a chart that shows only meaningful directional price action — making trends, support/resistance levels, and reversals visually clearer than on standard time-based charts.

What Is a Renko Chart? 

Most traders spend their careers looking at charts where time flows across the horizontal axis — every candle, bar, or data point representing a fixed interval of clock time. This convention is so ingrained in retail trading culture that it can be hard to imagine a price chart without a time dimension.

Renko charts discard time entirely. They have no time axis. There is no fixed period per brick. A brick can take five minutes to form or five hours — the chart doesn’t care. What matters is only one thing: has price moved by the brick size amount?

The name “Renko” derives from the Japanese word renga, meaning “brick” — a reference to the chart’s distinctive visual appearance of stacked rectangular blocks. This Japanese origin places Renko alongside candlestick charts and Kagi charts as part of a rich tradition of Asian price charting methodologies that prioritise price direction over time.

The practical result of Renko’s construction is a chart that:

• Stays static when markets are drifting or ranging without meaningful moves
• Adds new bricks only when price makes a decisive directional move
• Shows trends as clean, uninterrupted diagonal staircases of same-coloured bricks
• Shows reversals as sudden colour changes requiring significant price movement to trigger

For traders who struggle to distinguish genuine trends from market noise on time-based charts, Renko charts offer a fundamentally cleaner picture of what the market is actually doing. Brokers with TradingView integration — including Pepperstone, Eightcap, and ThinkMarkets — provide Renko chart access directly within their trading platforms.

The Origins of Renko Charts  

Renko charting has deep roots in Japanese technical analysis, with origins typically traced to the late 19th century — the same period that saw the systematic development of candlestick charting, Point and Figure analysis, and Kagi charting.

The technique was likely developed by Japanese rice traders who needed a way to track price momentum without the distraction of time-based fluctuations. A chart that only recorded “real” price moves — those large enough to represent genuine shifts in supply and demand — served this purpose far better than charts that plotted every tick in real time.

Renko charting remained largely a Japanese specialty until Steve Nison — the Western trader best known for introducing Japanese candlestick charting to Western markets — included Renko analysis in his 1994 book Beyond Candlesticks. This brought Renko methodology to the attention of Western technical analysts and began its gradual adoption on modern charting platforms.

Today, Renko charts are available on TradingView, some MetaTrader add-ons, cTrader, and other advanced charting platforms used by retail and professional traders worldwide.

How Renko Charts Are Constructed: Brick by Brick  

Understanding Renko chart construction from first principles eliminates most of the confusion beginners experience when first encountering them.

The Core Rule

A new brick is added to a Renko chart only when price moves by at least the brick size amount in one direction from the closing price of the most recently completed brick.

• If price moves up by the brick size → a new bullish brick (white/green) is added above the previous brick.
• If price moves down by the brick size → a new bearish brick (black/red) is added below the previous brick.
• If price moves by less than the brick size in either direction → no new brick is added. The chart remains unchanged.

The Reversal Rule

This is the critical element that distinguishes Renko from simple filtered bar charts:

To reverse direction and start a new column of bricks in the opposite direction, price must move by at least TWO brick sizes from the high or low of the current brick.

This means:

• If the chart is in a series of upward (bullish) bricks, a single brick-size move downward is not enough to trigger a reversal. Price must drop by two brick sizes from the top of the last bullish brick.
• This double-brick reversal requirement is the noise filter — it prevents every minor pullback within a trend from creating an apparent reversal.

Worked Example

Assume EUR/USD is being charted with a 10-pip brick size.

1. Price is at 1.1000. The last completed brick closed at 1.1000.
2. Price rises to 1.1010 → a new bullish brick is drawn from 1.1000 to 1.1010. ✅
3. Price rises to 1.1020 → another bullish brick added from 1.1010 to 1.1020. ✅
4. Price pulls back to 1.1015 → only a 5-pip drop from 1.1020. No reversal (needs 2 × 10 = 20 pips). ❌
5. Price rises to 1.1030 → another bullish brick. ✅
6. Price drops sharply to 1.1010 → a drop of 20 pips from 1.1030. Reversal triggered! ✅ Two new bearish bricks are drawn: 1.1030→1.1020 and 1.1020→1.1010.

Notice in step 6 that a two-brick reversal creates two bricks simultaneously, not one. This is normal Renko behaviour — when price moves decisively in the reverse direction, the chart “catches up” by plotting all the required bricks.

Brick Size: The Core Setting  

The brick size is the single most important configuration decision when setting up a Renko chart. It determines:

• How much price must move before any chart activity is recorded
• How much of the daily price range is filtered as noise
• How smooth or sensitive the resulting chart appears

Fixed Brick Size

A fixed brick size uses the same pip/point value for every brick regardless of market conditions or current price level.

Example settings for major forex pairs:

Limitation: A fixed brick size that works well during normal volatility becomes too sensitive during high-volatility periods and too slow during low-volatility periods.

ATR-Based Brick Size

The Average True Range (ATR) method dynamically adjusts the brick size based on recent market volatility. The brick size is set equal to the ATR over a defined lookback period (typically 14 periods on a daily chart).

This produces a brick size that:

• Automatically expands during high-volatility markets (larger bricks → fewer, more significant reversals)
• Automatically contracts during low-volatility markets (smaller bricks → more bricks, more responsive)
• Eliminates the need to manually re-tune the brick size as market conditions change

ATR-based Renko is widely considered the most robust and professional approach and is the default recommendation for serious traders. For traders who want to test ATR Renko settings across different instruments, a demo account at a broker with TradingView integration is the ideal environment — see Compare Forex Demo Accounts on CompareBroker.io.

How to Read a Renko Chart  

Reading a Renko chart is more intuitive than most traders expect, once the construction logic is understood:

Trend identification: A continuous series of same-coloured bricks moving in one direction indicates a clear trend. A staircase of bullish (white/green) bricks = uptrend. A staircase of bearish (black/red) bricks = downtrend.

Trend strength: The number of consecutive same-coloured bricks without a reversal indicates trend strength. Ten consecutive bullish bricks with no reversal signals a very strong uptrend. Three bullish bricks followed by two bearish bricks indicates a choppy, weak trend.

Reversal signal: The first brick of the opposite colour is the basic reversal signal. A colour change from bullish to bearish signals a potential shift to downside momentum; from bearish to bullish signals potential upside momentum.

Support and resistance: Price levels where Renko reversals have previously occurred — where bullish bricks changed to bearish or vice versa — represent significant support and resistance levels. The more reversals that have occurred at a specific price level, the stronger that level.

Consolidation/ranging: When the chart produces alternating bullish and bearish bricks without making sustained progress in either direction, the market is consolidating. In consolidating conditions, each brick is barely completed before a reversal occurs, creating a compressed, sideways appearance on the chart.

Renko Chart Trading Signals and Patterns  

Renko charts support both their own specific signals and adaptations of standard technical analysis patterns.

Basic Colour-Change Signal

The simplest and most widely used Renko signal is the colour change:

• Bullish signal: First white/green brick after a series of black/red bricks. Indicates a potential reversal from downtrend to uptrend.
• Bearish signal: First black/red brick after a series of white/green bricks. Indicates a potential reversal from uptrend to downtrend.

This signal is best used in combination with the broader context — a colour change at a major support level during an established uptrend is significantly more meaningful than a colour change during a choppy sideways market.

Double Bottom / Double Top on Renko

The double bottom pattern — two bullish reversals occurring at approximately the same price level — is highly readable on Renko charts because the chart’s noise-filtered construction makes the two reaction lows clearly visible without the surrounding price clutter of time-based charts. The same applies to double tops.

Support and Resistance Breakout

When Renko price action breaks decisively above a level where multiple previous bearish reversals have occurred, it signals a breakout above resistance. When it breaks below a level where multiple bullish reversals have historically occurred, it signals a breakdown below support.

Moving Average Crossovers on Renko

Adding two moving averages (e.g., a 10-brick and 20-brick simple moving average) to a Renko chart produces cleaner, more reliable crossover signals than the same MAs on a candlestick chart — because Renko’s noise-filtered bricks produce smoother MA lines with fewer false crossovers.

Head and Shoulders on Renko

The head and shoulders pattern appears on Renko charts — typically cleaner and more symmetrical than on time-based charts due to the noise-filtering effect of brick construction. The neckline break (a bearish colour change below the neckline level) confirms the reversal.

Renko Chart Trading Strategies 

Strategy 1: Colour Change + Moving Average Confirmation

Rules:

• Add a 10-period simple moving average to the Renko chart.
• Enter long (buy) when a bullish colour change occurs AND the brick is above the 10-period MA.
• Enter short (sell) when a bearish colour change occurs AND the brick is below the 10-period MA.
• Exit when the opposite colour change occurs.

This simple strategy keeps trades aligned with the short-term trend direction and filters out colour changes that occur against the prevailing trend.

Strategy 2: Renko Support/Resistance Breakout

Rules:

• Identify price levels where at least two previous Renko reversals have occurred (at similar price levels).
• Mark these as support (bullish reversal cluster) or resistance (bearish reversal cluster).
• Enter long when price breaks above a resistance cluster with consecutive bullish bricks.
• Enter short when price breaks below a support cluster with consecutive bearish bricks.
• Stop-loss: placed at the brick size below the entry for longs; brick size above for shorts.

Strategy 3: Renko + RSI or Stochastic

Because Renko charts filter time and noise, standard momentum oscillators applied to them produce cleaner signals. Combining the Stochastic Oscillator or Williams %R with Renko colour change signals provides momentum confirmation:

• A bullish colour change in oversold Stochastic territory = strong buy signal.
• A bearish colour change in overbought Stochastic territory = strong sell signal.

ATR-Based Renko: The Most Robust Approach  

As noted in the brick size section, ATR-based Renko is the professional standard. Here’s how to implement it:

1. On TradingView, open the Renko chart type.
2. In the chart settings, select ATR as the brick size method.
3. Set the ATR period to 14 (standard) on a Daily chart as the data source.
4. The chart will automatically calculate the ATR of the underlying daily data and use this as the brick size.

Result: During high-volatility markets (e.g., major news events, trending conditions), the ATR will be higher, creating larger bricks that filter out more noise. During calm markets, smaller bricks provide more granular price tracking.

The key advantage is that ATR Renko self-adjusts — you never need to manually recalibrate brick sizes when market conditions change. This is a significant practical advantage for traders who want a set-and-forget charting framework.

Renko Charts vs Candlestick Charts  

Candlestick charts remain the primary tool for most traders because of their universality and the rich information they provide (open, high, low, close within each period). Renko charts are best used as a complementary analytical tool — for confirming trend direction, identifying major support/resistance levels, and getting a cleaner strategic picture alongside candlestick entry charts.

Renko Charts vs Point and Figure Charts 

Both Renko and Point and Figure charts filter time and focus on price moves. Traders often ask which is better.

Renko’s 2-brick reversal produces slightly more frequent direction changes than P&F’s 3-box reversal, making Renko somewhat more responsive. P&F charts offer more sophisticated built-in target calculation (horizontal and vertical count). Neither is inherently superior — they serve the same purpose with slightly different mechanics.

Renko Charts vs Heikin Ashi Charts  

Heikin Ashi is another “smoothed” chart type that many traders compare to Renko.

Heikin Ashi retains the time axis — each candle still represents a fixed period — but uses a modified averaging formula to produce smoother candles. It is more accessible and more widely available than Renko, but provides less noise filtering because it still plots data for every time period including low-activity sessions.

Advantages of Renko Charts  

Superior noise filtering. The combination of fixed brick size and 2-brick reversal requirement filters out a far greater proportion of random price fluctuations than any time-based chart at an equivalent granularity level.

Trend clarity. An uptrend on a Renko chart looks like a clean staircase of bullish bricks. There is no ambiguity about trend direction, no need to draw multiple trendlines, and no confusion about whether a dip is a reversal or just noise.

Cleaner support and resistance. Because Renko filters out minor intraday fluctuations, the support and resistance levels that emerge from Renko reversal clusters are those where the market has genuinely changed direction — not where it briefly spiked intraday before recovering.

Reduces overtrading impulses. The chart’s static behaviour during consolidation periods naturally discourages impulsive entries during low-quality market conditions. The chart simply doesn’t change until there’s something worth looking at.

Compatible with all standard indicators. Every indicator available on standard charting platforms — moving averages, RSI, MACD, CCI, Stochastic — can be applied to Renko charts. The smoothed nature of Renko bricks often produces cleaner indicator readings than the same indicators on candlestick charts.

Adaptable to any market and any timeframe equivalent. By adjusting the brick size, Renko charts can be calibrated to function as a short-term scalping chart (small brick size) or a long-term position trading chart (large brick size) for any asset.

Limitations of Renko Charts  

No volume information. Standard Renko charts display no volume data. Since volume is one of the most important confirmation tools in technical analysis — particularly for validating breakouts and reversals — its absence is a significant limitation.

Gaps in historical data representation. Because Renko bricks are formed by price movement rather than time, the chart can create misleading representations of how long a move took. A brick that forms in 30 seconds during a fast-moving news event looks identical to a brick that forms over 3 hours during a quiet session.

Delayed reversal signals. The 2-brick reversal requirement means that by the time a colour change is confirmed, price has already moved two brick sizes from the high or low. In fast markets, this can represent a meaningful portion of the total move — producing entries that are later than ideal.

Brick size selection is subjective. Without ATR-based automation, choosing the right fixed brick size for current market conditions requires judgment and periodic recalibration. The wrong brick size produces either too many insignificant reversals (too small) or misses genuine trend changes (too large).

Limited platform support compared to time-based charts. Renko charts are not natively available on standard MT4 and MT5 installations. TradingView offers the best retail-accessible Renko implementation. For traders on MT4/MT5-only brokers, Renko access requires third-party custom scripts. Compare platform options at Best MT5 Brokers 2026 and Compare MT4 Brokers on CompareBroker.io.

Not beginner-appropriate as a standalone tool. Beginners should develop chart reading skills on standard time-based candlestick charts before exploring Renko. The lack of a time axis and the delayed reversal signals require contextual market knowledge that beginners haven’t yet developed. Start with the best beginner timeframe first.

Platform Availability: Where to Access Renko Charts  

Brokers offering TradingView integration provide the most accessible Renko experience for retail traders. The TradingView review on CompareBroker.io covers the platform’s capabilities in detail.

Frequently Asked Questions  

What is the best brick size for Renko charts in forex? For most forex traders, ATR-based brick sizing using a 14-period ATR on daily data is the best approach — it automatically adjusts to market volatility without manual recalibration. For fixed settings, 10–20 pips is a common starting point for EUR/USD medium-term swing trading. Always test settings on a demo account before applying them live. Compare demo accounts at Compare Forex Demo Accounts.

How is a Renko chart different from a candlestick chart? A candlestick chart forms a new candle after a fixed time period elapses, regardless of price movement. A Renko chart forms a new brick only when price moves by a fixed amount (the brick size). Renko charts have no time axis. They show only meaningful directional price moves and filter out small fluctuations, making trends and reversals cleaner and easier to identify.

Can I use technical indicators on Renko charts? Yes. All standard indicators — RSI, MACD, Stochastic, moving averages, Williams %R, CCI — can be applied to Renko charts on platforms that support them. The smoothed, noise-filtered nature of Renko bricks often produces cleaner indicator readings than the same indicators on time-based charts.

Is a Renko chart good for scalping? Renko charts can be used for scalping with small brick sizes, but they are more commonly associated with swing and position trading strategies that benefit from noise reduction. For scalpers specifically, the 2-brick reversal delay means entries are confirmed later than on real-time tick or M1 charts. See Best Scalping Brokers 2026 for the best execution environments if scalping is your focus.

What is the 2-brick reversal in Renko charts? The 2-brick reversal rule states that price must move at least two brick sizes in the opposite direction from the high or low of the current brick before a new reversal brick is plotted. This prevents every minor pullback within a trend from triggering an apparent reversal, keeping the chart focused on meaningful directional changes.

Are Renko charts available on MT4 and MT5? Not natively. MetaTrader 4 and 5 do not include Renko charts as a standard chart type. Access through MT4/MT5 requires third-party custom indicators or scripts. Renko is natively available on TradingView, cTrader, NinjaTrader, and ProRealTime. Traders specifically wanting Renko access should choose a broker offering TradingView or cTrader integration — compare options at Best MT5 Brokers 2026 and Compare All Brokers.

How does Renko compare to Point and Figure? Both chart types filter time and focus on price movement, but they differ in mechanics. Renko uses coloured bricks of fixed size with a 2-brick reversal. Point and Figure uses X’s and O’s in columns with a configurable multi-box reversal (usually 3). P&F offers built-in price target calculations (vertical/horizontal count); Renko uses standard measured move targets. Both are useful; neither is superior. See What Is a Point and Figure Chart? for the full comparison.
