Renko Chart is a Japanese price-action charting method that removes time from the x-axis entirely, plotting a new brick only when price advances or declines by an exact pre-set amount. Named from the Japanese word renga (brick) — the same country that produced candlestick charts and Heikin-Ashi — Renko charts reduce multi-day consolidations to silence and compress fast trending moves into a clear sequence of colored blocks.
Key Takeaways
- A new Renko brick prints only when price moves exactly the brick size — a three-day sideways session and a five-minute candle are treated identically.
- ATR(14)-based brick sizing adapts to volatility and outperforms fixed sizing for most instruments; for ES futures, 8–15 points per brick is a practical starting range.
- Volume data is not usable on Renko charts — always confirm entries on a companion time-based chart before executing.
How Renko Charts Work
Each brick on a Renko chart represents a fixed price move. When the closing price (or last traded price, depending on platform settings) advances by the brick size above the top of the last green brick, a new green brick is added. When price drops by the brick size below the bottom of the last red brick, a new red brick is added. Nothing else generates a brick — not the passage of time, not a half-brick move, not a gap open that doesn’t clear the threshold.
Brick size configuration is the most consequential decision:
- Fixed brick size: Simple and consistent. A $1 brick on a $50 stock requires a 2% move per brick. Limitation: the same dollar amount is too granular at low volatility and too coarse at high volatility.
- ATR-based brick size: The brick size is set equal to the ATR over a lookback period, typically ATR(14). This is the default in TradingView and NinjaTrader. For ES futures trading near 5,000, ATR(14) on a daily chart typically runs 8–15 points. For EUR/USD forex, 10–20 pips is a standard ATR-derived starting point.
Reversal bricks require 2x the brick size to form. With a 10-point brick, price must fall 20 points from the most recent high before a red brick appears after a green sequence. This built-in threshold eliminates many whipsaw entries that would trigger on a standard candlestick chart.
Entry and exit signals on Renko are simpler than most candlestick patterns:
- Entry trigger: three consecutive same-color bricks
- Exit/stop trigger: one completed reversal brick (2x brick size in the opposite direction)
Practical Example
A swing trader monitors ES futures on a daily Renko chart with ATR(14) brick size set to 10 points. The market has printed a mixed sequence of alternating red and green bricks for several sessions — the Renko chart shows nothing actionable. Then, three consecutive green bricks form, signaling a confirmed uptrend.
- Entry: 5,210
- Brick size: 10 points = $500 per contract (ES multiplier: $50/point)
- Stop: One reversal brick below entry = 5,190 (20-point drop required), risking $1,000 per contract
- Target: 6 bricks = 60 points = $3,000 per contract, a 3:1 reward-to-risk ratio
During those same sessions, a candlestick chart showed three days of tight-range candles — enough to shake out traders using time-based stops. The Renko chart printed nothing and preserved the position.
Note: volume data on this chart is not usable. Before entry, confirming with a daily candlestick chart that volume was expanding on up-days strengthens the conviction in the setup.
A Renko chart replaces time-based candles with fixed-size price bricks. A new brick only appears when price moves a set amount. This filters out sideways noise and makes trends easy to see, but removes all time and volume context from the chart.
Common Mistakes
- Setting brick size too small. A 1-point brick on ES produces a chart as noisy as a 1-minute candlestick. The ATR(14) value is a reliable floor for brick size — going below it defeats the purpose of the chart type.
- Setting brick size too large. A 50-point brick on ES delays signals until after a significant move has already occurred. Test with ATR(14) as the baseline, then adjust ±20% based on historical signals.
- Ignoring volume entirely. Because each brick covers a different elapsed time, the volume number attached to a Renko brick means nothing. Skipping volume confirmation on a separate chart is one of the most common execution errors Renko traders make.
- Applying Renko to non-trending instruments. Renko’s edge is trend capture. In range-bound markets, reversal bricks generate a stream of entries and exits that produce chop. Check ADX on a standard chart first — Renko signals in a low-ADX environment have poor expected value.
How JournalPlus Tracks Renko Chart Signals
JournalPlus lets traders tag each trade with a chart type and brick size so win rate, average win, and average loss can be filtered by configuration. Over a sample of 50+ trades on the same instrument, this reveals whether an 8-point or 12-point ATR brick is producing better outcomes — the fastest empirical path to optimizing the parameter. The trade log also timestamps each entry, so Renko signals can be cross-referenced with the time-based volume data that the chart itself cannot provide.
