Renko charts are used in technical analysis to simplify price action and help identify trending and non-trending markets. When compared to traditional candlestick charts, Renko charts are unique in that they are built solely on price movement without taking time into account.
Created in Japan, Renko bars are thought to have gotten their name from the Japanese word for bricks, renga. Each new Renko bar, or “brick,” is formed only after price has moved a specified amount, known as the brick size. This differs from traditional candles which are formed after a specified period of time has elapsed.
Additionally, Renko bricks are always positioned at a 45-degree angle either up or down from the previous brick and never side-by side, as seen in the chart below.
Renko Based Solely on Price
In the chart below, a traditional 15-second candlestick chart is shown with alternating gold and black sections to denote when each minute of time passed. Since traditional candles are a time-based interval, each minute is represented with the same distance on the x-axis (even intervals).
In the next example, a 2-tick Renko chart is shown over the same period of time. Since Renko bars are formed based on price information alone with no regard to time, each minute of time contains a varying amount of bricks. Although Renko charts are not time-based, the passage of time is still represented on the x-axis.
Track Trending vs Choppy Markets
Renko bars can be especially useful for identifying when a market is in a trend vs trading sideways. The chart below, created 100% for free using NinjaTrader, shows price action in Crude Oil futures based on a 20-tick brick size. A potentially trending market can be identified by areas with several consecutive green or red bricks, and choppy, whipsaw trading can be detected by alternating red and green bricks.
