What is a Renko Chart?
A Renko chart is a visually distinct chart type used in financial trading that displays price movements with bricks, eschewing standard time intervals common to most chart types. Originated in Japan, Renko means ‘brick’ in Japanese, reflecting the chart’s brick-like structure. Each brick on a Renko chart is placed at a 45-degree angle from the previous one, indicating a specified and consistent price move, either upward or downward. By focusing solely on significant price moves, these charts aim to eliminate the ’noise’ that minor fluctuations create, offering traders a cleaner and easier view of trends.
How Renko Charts Operate
Renko charts are based on price change and not on time. Here’s what this means in practice:
- Brick Construction: Each brick represents a fixed price movement, known as the box size, which could be set to any value—like $1 or $10, or dynamically using the Average True Range (ATR) to adjust to market volatility.
- Directional Bricks: If the price increases by the box size, a new brick is added in the upward direction; if it decreases by the same, a brick is drawn downward.
- Color Coding: Typically, upward bricks are colored white or green, while downward bricks appear red or black, making it straightforward to discern market trends at a glance.
Analytical Insights from Renko Charts
Renko charts abstract away the finer details of temporal price movements to focus on substantial trends. This can be both a boon and a bane:
- Enhanced Trend Visualization: By filtering out less significant price variations, Renko charts help traders identify and follow market trends without the distraction of short-term fluctuations.
- Omission of Minor Movements: While this can help maintain focus on the bigger picture, some relevant price actions that might affect decision-making can be omitted.
Using Renko Charts in Trading
Integration of Renko charts into a trading strategy allows traders to potentially enhance their market analysis:
- Trend Confirmation: A series of bricks in the same color can confirm the strength and stability of a trend.
- Signal Generation: Changes in brick color can indicate trend reversals, providing actionable trading signals.
- Support and Resistance Levels: Renko charts can help identify key price levels, which are not distorted by insignificant price movements.
Potential Limitations
Despite their simplicity and effectiveness in trend analysis, Renko charts may not be universally suitable:
- Delayed Reactions: Because these charts only reflect price movement, responses to actual market events might be delayed.
- Fixed Box Size Issue: Inflexibility in the box size setting might result in missing out on important market nuances or over-emphasizing insignificant trends.
