Renko charts - Clean out the noise
I recently attended a talk by Stephen Hoad on behalf of the STA for the CISI, where he discussed his use of Renko charts. Well, it piqued my interest and I decided to take a closer look myself.
Renko charts were invented in Japan, they ignore time and just use price changes that meet a minimum requirement, which to my mind sounds exactly like Point & Figure charts (I love these). Instead of X-Columns and O-Columns, Renko charts use price “bricks” that represent a fixed price move. These bricks are sometimes referred to as “blocks” or “boxes.” They move up or down in 45-degree lines with one brick per vertical column. Bricks for upward price movements are one colour while bricks for falling price movements are filled in another colour. In the example attached I have a chart of the US Dollar Index, where upward price moves are green and downwards are red. This example uses a 0.5 brick size.
Please note the irregular time span along the y-axis. Also note that it uses an average true range of 14 days. For an explanation of average true range (ATR) please follow this link school.stockcharts.com/doku.php?id=technical_indicators:average_true_range_atr.
N.B when adding indicators say a 20-period moving average, this will be based on the last 20 Renko values NOT the last 20 days.
I always think that these types of charts look optically ‘cleaner’ or clearer than the more typical bar chart. They completely ignore time, and a brick is only drawn if price moves by a set amount. If it moves less than the set amount, no brick is drawn.
In contrast to fixed price bricks, using ATR values results in fluctuating brick sizes. The default ATR is based on 14 periods and the Average True Range fluctuates over time. The brick size is based on the ATR value at the time the chart is created. Should the ATR value change the next day, then this new ATR value will be used to set the brick size. Also note that ATR values are based on standard charts, such as close-only, bar and candlestick.
