Introduction to Renko charts
Renko charts, originating in Japan, are a distinctive form of financial charting that stands apart from traditional candlestick or bar charts. They derive their name from the Japanese word “renga,” which translates to “bricks,” reflecting the chart’s appearance as a series of bricks. unlike conventional charts that rely on both price and fixed time intervals, Renko charts are built solely on price movement.
Key Characteristics of Renko charts
Renko charts exhibit several unique features:
Brick Formation
A Renko chart is composed of bricks, each of which represents a specified price movement. typically, an up brick is colored white or green, while a down brick is black or red. These bricks are positioned at a 45-degree angle to the right of the prior one, and they do not appear consecutively.
Box Size
The size of a brick, known as the box size, can vary and is determined by the trader. It can represent a fixed price increment, such as $0.10, $0.50, or any amount chosen. Alternatively, traders can opt for a box size based on the Average True Range (ATR), a measure of volatility.
Time Axis
While Renko charts do include a time axis, the time scale is not fixed. Bricks may take different durations to form, depending on the time it takes for the price to move the chosen box size.
Filtering Noise
Renko charts are exceptional at filtering out noise in price movements, making it easier for traders to identify and focus on significant trends. Movements smaller than the box size are ignored, providing a clearer picture of the market’s direction.
Use of Closing Prices
Typically, Renko charts rely on closing prices based on the selected chart time frame. For example, when using a weekly time frame, the bricks are constructed using weekly closing prices.
What can you learn from a Renko chart?
Renko charts are designed to simplify the process of identifying trends by filtering out minor price fluctuations. However, this simplicity comes at the cost of losing some detailed price information. Here’s how to interpret Renko charts:
Choosing the box size
The first step in constructing a Renko chart is selecting an appropriate box size that reflects the desired price movement magnitude. For instance, a stock trader might choose a $0.25 box size, while a currency trader might opt for a 50 pip box size. A new brick is formed in the next column when the price surpasses the top or bottom of the previous brick by the box size amount.
Consider a stock trading at $10 with a $0.25 box size. A new brick is drawn only when the price closes at $10.25 or higher. If the price reaches $10.24, no new brick appears. Importantly, once a brick is drawn, it is not deleted.
Brick Arrangement
Renko bricks are not drawn consecutively. For instance, if the stock price drops back to $10.25, a down brick will not immediately follow the prior up brick. Instead, the price must drop to $10 for a down brick to appear beneath the prior up brick.
Using ATR for Box Size
While a fixed box size is common, traders can opt to use the Average True Range (ATR) as a dynamic box size. ATR fluctuates over time, reflecting changes in market volatility.
Time Intervals
Renko charts include a time axis, but the intervals are variable. A single brick may take months to form, while several bricks may emerge within a single day. This contrasts with candlestick or bar charts, where new candles/bars form at fixed time intervals.
Box Size and Trend Smoothness
Adjusting the box size affects the smoothness of the chart. Smaller box sizes create more swings and highlight potential price reversals earlier. In contrast, larger box sizes reduce noise but may be slower to signal reversals.
Identifying Support and Resistance
Renko charts excel at pinpointing support and resistance levels due to their reduced noise compared to candlestick charts. During strong trends, Renko traders can capitalize on these trends for extended periods before a reversal signal appears.
Trading Signals
Trading signals are typically generated when the trend direction changes, and the bricks alternate colors. For example, a trader might sell an asset when a red brick appears after a series of ascending white bricks. Conversely, in an uptrend (characterized by white/green bricks), a trader might enter a long position after one or two red bricks (a pullback).
Example of how to use Renko charts
Let’s illustrate the practical application of Renko charts with an example:
Consider a stock with a $2 box size, where bricks are drawn based on closing prices. Highs, lows, and price movements smaller than $2 are disregarded. In the chart, a strong uptrend is evident, marked by green boxes. A brief pullback is represented by a red box, followed by a resurgence of green boxes. Traders could interpret this as an opportunity to enter a long position, considering an exit when another red box appears.
Subsequently, a notable downtrend emerges. A similar approach could be taken for a short entry, waiting for a pullback marked by a green box and entering a short position when a red box forms. Exiting the short position could be considered when an up box occurs.
It’s worth noting that these are sample guidelines, and some traders may prefer to see multiple bricks in a specific direction before making entry or exit decisions.
The difference between Renko charts and Heikin Ashi charts
Renko charts share some similarities with Heikin Ashi charts, both of which highlight sustained trends. However, there are differences:
Renko Charts:
– Use a fixed box size.
– Base their bricks solely on price movement.
– Ignore highs and lows.
– Provide a clear trend representation.
– Use a fixed box size.
– Base their bricks solely on price movement.
– Ignore highs and lows.
– Provide a clear trend representation.
Heikin Ashi Charts:
– Use an average of open, high, low, and close prices.
– Reflect different box or candle sizes.
– Include more price data.
– Highlight trends similarly to Renko charts.
– Use an average of open, high, low, and close prices.
– Reflect different box or candle sizes.
– Include more price data.
– Highlight trends similarly to Renko charts.
Limitations of using Renko charts
While Renko charts offer distinct advantages, they also have limitations:
Lack of detail
Renko charts may not provide as much detail as candlestick or bar charts, especially for assets that have traded within a narrow range for an extended period. A single brick represents this entire period, potentially missing important price movements.
Ignoring highs and lows
Renko charts only consider closing prices, omitting high and low prices. This can lead to significant price breaks occurring before a new brick forms, potentially causing losses.
False signals
Renko charts can produce false signals when brick colors change prematurely, resulting in whipsaw effects. To mitigate this, traders often combine Renko charts with other technical analysis tools.
Setting up Renko charts on popular platforms
Thinkorswim
Thinkorswim, a widely-used trading platform from TD Ameritrade, allows users to display Renko charts. To do this, access the “Chart Styles” menu and change the “Range Type” to Renko Bars. Adjust the price range to match your desired box size.
TradingView
TradingView, a popular charting platform, offers Renko charts with a paid subscription. Navigate to the chart menu, select “Renko,” and customize your box size in the settings menu.
Choosing the right box size
Selecting the appropriate box size depends on factors such as your trading time horizon, risk tolerance, and goals. Larger box sizes suit longer-term trading but carry higher risks, as they may overlook smaller price fluctuations.
In conclusion, Renko charts provide traders with a unique perspective on price movements, emphasizing trends while reducing noise. By understanding their characteristics, interpretation, and limitations, traders can use Renko charts as a valuable tool in their technical analysis toolkit.
Utilizing Renko charts for swing trading
Swing trading is a popular strategy among traders who aim to capture short to medium-term price swings within a larger trend. Renko charts can be a valuable tool for swing traders due to their ability to filter out noise and highlight significant price movements. In this example, we’ll explore how swing traders can effectively use Renko charts to identify entry and exit points.
Entry points
When swing trading with Renko charts, traders often look for entry points when a new brick forms in the direction of the prevailing trend. For instance, in an uptrend marked by a series of ascending white bricks, a swing trader might enter a long position when a new white brick appears after a pullback represented by red bricks. This entry strategy aligns with the overall trend, increasing the likelihood of a profitable trade.
Exit points
Determining exit points is crucial in swing trading. Renko charts can assist in this aspect as well. Swing traders may consider exiting their positions when a brick of the opposite color to their trade direction appears. For instance, if a trader is in a long position and a red brick forms after a series of white bricks, it could signal a potential trend reversal, prompting the trader to exit the trade to lock in profits or limit losses.
Combining Renko and moving averages for enhanced analysis
To further enhance your technical analysis using Renko charts, consider combining them with moving averages, a widely used trend-following indicator. This combination can provide additional confirmation of trends and help traders make more informed decisions.
Identifying trend continuation
When using Renko charts in conjunction with moving averages, traders can identify trend continuation opportunities. For instance, if the Renko chart displays a strong uptrend with a series of ascending white bricks, the inclusion of a moving average, such as the 50-day or 200-day, can validate the trend’s strength. When the Renko bricks remain consistently above the moving average, it suggests a robust uptrend, providing traders with confidence to stay in their positions.
Spotting potential reversals
Combining Renko charts and moving averages can also help traders identify potential trend reversals. For instance, if the Renko chart shows a series of descending red bricks, and the price approaches a key moving average, it could signal a reversal point. Traders may consider this a potential exit point for existing positions or even an opportunity to enter a new trade in the opposite direction if supported by other technical indicators.
