Summary
- The Stochastic Momentum Index (SMI) Ergodic is a leading momentum oscillator that predicts price reversals by generating buy/sell signals. It excels in trending markets, where directional predictability allows traders to capitalize on sustained movements.
- Functionally similar to the True Strength Index (TSI), the SMI Ergodic enhances accuracy through a signal line and double smoothing. Its TSI foundation makes it one of the most reliable standalone oscillators.
- Unique among indicators, it combines EMA-derived price data with smoothing techniques for high signal precision, reducing the need for additional confirmation tools.
Understanding the SMI Ergodic Indicator
The SMI Ergodic is a momentum oscillator blending the TSI’s formula with a signal line, designed for trend trading and reversal prediction. Its complexity belies its utility—ranked among the top 10 most accurate trend indicators.
Key Features:
- EMA-Based Calculations: Prioritizes recent price data for responsiveness.
- Signal Line Integration: Improves TSI’s accuracy by filtering false signals.
- Leading Indicator: Predicts trends early due to EMA weighting.
💡 Pro Tip: The "Ergodic" term reflects its mathematical approach, using historical price averages to forecast future movements—akin to predicting coin flip outcomes based on past results.
SMI Ergodic Indicator Formulas
The indicator uses three core formulas:
SMI Line (Blue) = [PCDS / APCDS] × 100
- Derived from double-smoothed EMA price closes.
Histogram Oscillator (Red) = TSI – (EMA × TSI)
- Visualizes momentum strength relative to the signal line.
Signal Line (Orange) = EMA × TSI
- Smoothed TSI values generating crossover signals.
Default Settings:
- Long Length (SMI): 20-period
- Short Length (Signal/EMA): 5-period

Interpreting the SMI Ergodic
Key Components:
- SMI/TSI Line (Blue): Primary momentum line.
- Signal Line (Orange): Triggers crossovers for entries/exits.
- Histogram (Red): Indicates trend strength (above/below zero line).
Trading Signals:
- BUY: Blue line crosses above orange line + histogram above zero.
- SELL: Orange line crosses above blue line + histogram below zero.
![Example: Crossover signals align with trend shifts, as seen in ETH/USDT charts.]
Trading Strategies with the SMI Ergodic
1. Crossover Strategy
- Enter long when the SMI line crosses above the signal line and the histogram is bullish.
- Exit or short on the opposite crossover.
2. Histogram Divergence
- Trade reversals when the histogram deviates beyond ±0.1 on daily charts.
3. Trend Confirmation
- Use prolonged histogram expansions to validate trend persistence.
⚠️ Risk Note: Always confirm crossovers with histogram alignment to avoid choppy-market false signals.
FAQs
Q1: Can the SMI Ergodic be used alone?
Yes—its EMA smoothing and signal line reduce reliance on secondary indicators.
Q2: How does it compare to the MACD?
Both use signal lines, but the SMI Ergodic’s double smoothing offers earlier reversals signals.
Q3: Best timeframes for the SMI Ergodic?
Works on all timeframes, but 5:20:5 settings suit trend traders; longer periods (50+) fit swing trading.

Conclusion
The SMI Ergodic stands out for its accuracy and versatility, combining TSI momentum tracking with EMA responsiveness. Whether for crossovers or trend confirmation, it’s a powerhouse for traders prioritizing precision.
Final Tip: Pair it with volume indicators (e.g., OBV) to filter false breakouts.
