description: Honest Kaufman_Efficiency_Ratio review: measures trend efficiency vs noise. Covers settings, entry/exit logic, and real-world performance. Not a holy grail, but a solid filter.
I’ll cut to the chase: the Kaufman_Efficiency_Ratio isn’t going to make you a millionaire overnight. But if you’re tired of choppy, sideways markets that chew up your stop-losses, this indicator might be the filter you’ve been missing.
I’ve spent the last few weeks running this on ES, NQ, and a handful of FX pairs. Here’s what I found.
What This Indicator Actually Does
The Kaufman Efficiency Ratio (ER) isn’t a new invention—it’s a classic from Perry Kaufman’s Trading Systems and Methods. This TradingView version calculates the ratio of price direction (net change over a period) to price volatility (sum of absolute price movements over the same period).
- ER = 1 means price is moving perfectly in one direction (pure trend).
- ER = 0 means price is going nowhere fast (pure noise).
The indicator plots this as a single line, often with a moving average or threshold lines. The chart above shows it as a blue line oscillating between 0 and 1, with a dashed horizontal at 0.5 acting as a rough trend/noise divider.
Key Features That Set It Apart
- Simple, clean visual. No clutter. Just one line. You can add your own thresholds or moving averages.
- Adaptive by design. Unlike RSI or ADX, ER adapts to the market’s own volatility. It doesn’t use arbitrary overbought/oversold levels.
- Customizable period. The default is 10, but you can tweak it. Longer periods smooth out noise but lag more. I found 14 works well for daily charts, 8 for intraday.
Best Settings with Specific Recommendations
I tested these combinations across multiple timeframes:
| Timeframe | Period | Threshold (trend) | Threshold (noise) |
|---|---|---|---|
| 1H | 8 | > 0.6 | < 0.3 |
| 4H | 12 | > 0.65 | < 0.35 |
| Daily | 14 | > 0.7 | < 0.4 |
Pro tip: Don’t use fixed thresholds blindly. On ES (which trends well) you can push the trend threshold to 0.75. On GBP/JPY, you’ll want it around 0.6 because it’s choppier.
How to Use It for Entries and Exits
This is where most traders get it wrong. The ER alone is not a timing signal. It’s a filter. Here’s how I use it:
Trend entry (long):
- ER > 0.7 (daily) = strong trend.
- Wait for a pullback to a key moving average (e.g., 20 EMA).
- Enter on a bullish candlestick close.
Exit:
- If ER drops below 0.4, the trend is weakening. Take partial profits.
- If ER falls below 0.2, the trend is dead. Exit fully.
Avoiding chop:
- If ER is between 0.3 and 0.6, stay out. Period. This saved me from at least three false breakouts last week.
Honest Pros and Cons
Pros:
- Excellent at filtering out sideways markets.
- Works on any timeframe or asset.
- No repainting (as long as you use the standard version).
Cons:
- Laggy on low periods (below 8). You get whipsaws.
- Doesn’t tell you direction—only efficiency. You need another tool for that.
- Thresholds are asset-specific. No universal “best” setting.
Who It’s Actually For
- Swing traders who want to avoid choppy weeks.
- System traders looking for a trend filter to add to a strategy.
- Anyone using ATR or ADX who wants a simpler, more responsive alternative.
It’s not for scalpers. The ER is too slow for 1-minute charts.
Better Alternatives If They Exist
- ADX – Similar concept but uses DMI+ and DMI- for direction. ADX is slower but gives trend strength and direction.
- Choppiness Index – Plots in a 0–100 range. Better for identifying range-bound markets outright.
- KAMA (Kaufman Adaptive Moving Average) – Uses the ER internally to adjust its smoothing. More practical if you want a moving average that reacts to noise.
If I had to pick one, I’d take Choppiness Index over ER for pure chop detection. But for trend strength, ER wins.
FAQ: Real Trader Questions
Q: Does it repaint?
A: The standard version doesn’t. But some user-modified versions with smoothing might. Stick with the original.
Q: Can I trade solely on ER?
A: No. You’ll get killed. Use it as a filter, not a standalone signal.
Q: What’s the best period for crypto?
A: Crypto is noisy. I use 20 on daily charts. Threshold: 0.65 for trend, 0.3 for noise.
Q: How is this different from RSI?
A: RSI measures momentum (speed of price change). ER measures efficiency (directional consistency). They’re complementary.
Final Verdict
The Kaufman_Efficiency_Ratio is a solid workhorse for anyone who trades trends. It won’t replace your main entry system, but it will keep you out of the worst markets. For a free community indicator, the code is clean and the logic is transparent.
Rating: ⭐⭐⭐⭐ (4/5)
One star deducted because it’s not a complete system—you still need direction and entry logic. But for what it does, it’s excellent.
