Renko Charts

Renko charts represent a fundamentally different approach to price visualization. Named after the Japanese word "renga" (brick), these charts ignore time completely and only create a new brick when price moves by a predetermined amount. The result is a chart that strips away all noise and reveals trend structure with remarkable clarity.

Each brick has a fixed size, measured in pips or points. If you set a brick size of 10 pips on EUR/USD, a new green (up) brick only forms when price rises 10 pips from the previous brick's top. A new red (down) brick forms when price falls 10 pips from the previous brick's bottom. Because a reversal requires the full brick size from the opposite end, it takes twice the brick size to reverse direction — a built-in noise filter.

This time-independent construction creates charts where every brick represents the same magnitude of price movement. During active markets, bricks form rapidly. During quiet periods, no bricks appear at all. This automatically highlights when the market is moving and hides the choppy, sideways periods that plague standard chart analysis.

Trend identification becomes trivially easy. A sequence of green bricks is an uptrend. A sequence of red bricks is a downtrend. A color change signals a reversal. You can apply any standard indicator — moving averages, RSI, support/resistance — to Renko charts, and they'll produce cleaner signals because the underlying data is already filtered.

Setting the brick size is the most important decision. Too small, and you'll get noisy charts similar to standard candles. Too large, and you'll miss meaningful moves. The best practice is to use ATR as a guide: set the brick size equal to the current daily ATR, or a fraction of it for shorter-term trading. This auto-calibrates the sensitivity to the instrument's current volatility.

On MT4, Renko charts aren't available natively. You'll need a custom indicator or offline chart script to generate them. The most common approach uses an Expert Advisor that creates an offline chart file with Renko bricks. MT5's custom symbol feature makes the process somewhat easier, though it still requires a script. Despite the setup effort, many traders consider Renko charts essential for swing trading and position management due to the unparalleled clarity they provide.

The Renko moving average strategy applies a simple moving average (10-period is common) to the Renko chart. Buy when a green brick closes above the MA. Sell when a red brick closes below it. Because Renko bricks are already noise-filtered, the MA signals are significantly cleaner than on standard charts. This double-filtered approach catches only the strongest trend changes.

For support and resistance trading, horizontal lines on Renko charts are remarkably clean. Identify levels where price has reversed multiple times and trade the bounces. Because Renko removes time-based noise, the support/resistance levels tend to be more precise and reliable. Set your stop one brick beyond the level and target the next level for a structured risk-reward setup.

The Renko reversal strategy is simple but effective: enter long when a green brick appears after three or more consecutive red bricks. Enter short when a red brick appears after three or more green bricks. The longer the preceding sequence, the stronger the reversal signal. This is because longer brick sequences represent established trends, and the first reversal brick after such a sequence carries more weight than a reversal after just one or two bricks.
