Renko charts are one of the best ways to analyze price movements of the financial assets and also filter out minor price movements.
When these small fluctuations in price movements are removed then the price trends can be easily spotted with a Renko chart.
This is the reason why traders prefer Renko charts as price charts when trading in the stock market.
Renko charts are also easier to read as the bricks, boxes, or blocks are more uniform as compared to candlestick charts.
In this blog, we will discuss the basics of Renko charts and how to trade with the same:
What are Renko Charts?
Many people think that the Renko chart has got its name from the Japanese word for bricks, “Renga” as it resembles a series of bricks.
In the Renko charts, a new brick is formed when the price of an asset moves a certain price amount.
Traders can also place each block at a 45-degree angle either up or down to the previous brick.
Usually, the up brick has a white or green colour whereas the down brick has a black or red colour. A Renko chart mainly shows price movements in financial markets.
Renko charts are made up of blocks that have the same size. The blocks can either be green or red just like in a candlestick chart.
Renko charts have individual blocks of the same size as the chart doesn’t consider time.
The Renko chart has a setting parameter for the size of the bricks specified by the traders for each brick.
How to construct Renko Charts?
As we have discussed above, Renko charts are constructed using bricks having a fixed value which filters out smaller price movements
This is the reason why thesecharts take only one piece of data per day or week. One should note that Renko charts ignore the time aspect and only focus on price changes.
For example, If the brick value is set at 50 points, then a move of 50 points is required to draw another brick as shown in the below chart of Reliance India Ltd.
Price movements less than 50 points would be ignored and another brick will not be formed in the Renko chart.
Types of Renko charts:
There are usually two types of Renko charts that depend on the calculation used. These are high/low charts and open/close charts.
1. High/Low Renko Chart
This type of Renko chart takes into consideration the behaviour of each price action. It consists of price action between the highest and the lowest price on the chart.
2. Open/Close Renko Charts
This Renko style takes only those price moves that are found within the Open/Close range of the price action.
How to determine the box value?
Traders can use the “box” settings for setting the brick size that can be set as a specific value or as the Average True Range (ATR).
A specific point value means the brick size will remain constant even when new data is added to the chart.
The above chart of Reliance India Ltd. as shown above has a fixed value and each brick represents fifty points.
On the other hand, ATR values result in the fluctuating of the brick sizes. The default ATR is of 14 periods and it fluctuates over time as shown below:
Trading using Renko Charts:
Traders can use troughs for marking support levels and peaks for marking resistance levels. They can also look for a two brick reversal that signals a trend change.
Green bricks are formed when prices rise a certain amount and red bricks form when prices decline a certain amount.
The chart below shows a daily Nifty 50 chart and a 10-period simple moving average.
One should remember that an indicator on a Renko chart depends on the Renko values and will differ from the same indicator on a bar chart.
Traders should use shorter moving averages on Renko charts as smaller price movements have already been filtered out.

Advantages of using the Renko chart:
Renko charts do not include the time aspect and thus filter out noises and small price movements on the charts.
Decreasing or increasing the size of the box will affect how smooth the chart will be. Lowering the size of the box will make more swings, but will also show possible price reversals quicker. Big box size will lower the number of swings and noise but will be slower to show a reversal price.
Limitations of Renko charts:
Renko charts do not show in detail the price movements as bar or candlestick charts because they do not track time
Thus, this fails to tell the traders what has occurred during that period.
Difference between Renko Charts and Candlestick Chart:
The main difference between the Renko chart and the candlestick chart is that Renko charts are smoother than the candlestick charts. The same also holds for an OHLC (open, high, low, close) bar chart.
This is the reason that when we compare a Renko chart and a candlestick chart, the price movements on the candlestick chart will change directions more often.
Another difference between the two types of charts is that a Renko chart doesn’t always give us the most current information. As the Renko chart updates only when a new brick is formed and the candlestick chart always shows the last price.
