The Chande Momentum Oscillator (CMO) is a powerful yet often overlooked technical indicator that delivers a balanced view of market momentum. While many traders gravitate toward more popular oscillators like the Relative Strength Index (RSI) or Stochastic, the CMO stands out for its unique calculation method and reliability in identifying momentum shifts. This guide explores how the CMO works, its practical applications, and how to integrate it into a high-probability trading strategy.
What Is the Chande Momentum Oscillator?
Developed by Tushar Chande in 1994, the Chande Momentum Oscillator measures an asset’s momentum by calculating the difference between total recent gains and total recent losses over a defined period. The result is normalized to oscillate between +100 and -100, offering a symmetrical range that reflects both bullish and bearish momentum with equal weighting.

Unlike the RSI, which ranges from 0 to 100 and inherently favors upward momentum, the CMO treats gains and losses equally. This balanced approach reduces bias and provides a clearer picture of true price momentum, making it especially useful in trending and volatile markets.
Traders use the CMO to identify:
- Overbought and oversold conditions
- Divergence signals
- Trend direction via zero-line crossovers
Its versatility allows application across various financial instruments, including forex pairs like USDJPY and EURCHF, cryptocurrencies, and equities.
How to Calculate the Chande Momentum Oscillator
The formula for the CMO is straightforward:
CMO = [(Sum of Gains – Sum of Losses) / (Sum of Gains + Sum of Losses)] × 100
Where:
- “Gains” are positive price changes over the selected period
- “Losses” are negative price changes (expressed as absolute values)
- The default period is typically 9, but can be adjusted
For example, if over nine periods, gains total $60 and losses total $40:
CMO = [(60 – 40) / (60 + 40)] × 100 = (20 / 100) × 100 = +20
This value would appear on the oscillator as +20, indicating moderate bullish momentum.
While most trading platforms automatically compute the CMO, understanding the math behind it helps traders interpret signals more accurately—especially during rapid price swings or consolidation phases.
How to Use the Chande Momentum Oscillator
The CMO is a multi-functional tool. Here are three primary ways traders apply it:
1. Overbought and Oversold Levels
The CMO’s range from +100 to -100 makes it ideal for spotting extremes:
- Above +50: Asset is overbought — price may correct downward
- Below -50: Asset is oversold — rebound likely
However, in strong trends, overbought or oversold readings can persist. Therefore, always align these signals with the broader trend. For instance:
- In an uptrend, only consider oversold bounces as buying opportunities
- In a downtrend, treat overbought levels as potential short entries
2. Divergence Detection
Divergence occurs when price and momentum move in opposite directions:
- Bullish Divergence: Price makes lower lows, but CMO forms higher lows → suggests weakening bearish momentum
- Bearish Divergence: Price makes higher highs, but CMO shows lower highs → signals fading bullish strength
These setups often precede reversals and are among the most reliable CMO signals when confirmed with price action.
3. Zero-Line Crossover
Crossing the zero line indicates a shift in momentum:
- CMO > 0: Bullish momentum dominates
- CMO < 0: Bearish momentum takes control
Traders often use zero-line crossovers as entry triggers when aligned with trend-following indicators.
Chande Momentum Oscillator Trading Strategy
To maximize accuracy, combine the CMO with trend confirmation tools. One effective setup pairs the CMO with 9- and 21-period Exponential Moving Averages (EMAs).
Trade Setup
- Apply the 9 EMA (fast) and 21 EMA (slow) on your chart
- Add the CMO (default 9-period) below the price chart
Trend Filter:
- Bullish Trend: 9 EMA > 21 EMA
- Bearish Trend: 9 EMA < 21 EMA
Entry Rules:
- Buy Signal: CMO crosses above zero and 9 EMA is above 21 EMA
- Sell Signal: CMO crosses below zero and 9 EMA is below 21 EMA

Trade Management
- Stop Loss: Place below the most recent swing low (for longs) or above swing high (for shorts)
- Take Profit: Aim for a 1:2 risk-to-reward ratio
- Exit Trigger: Close positions when the 9 EMA crosses the 21 EMA in the opposite direction
This strategy works best on 4-hour and daily timeframes, where trends are more stable. Instruments like USDJPY and EURCHF, known for sustained directional moves, yield optimal results.
Benefits and Limitations of the CMO
Advantages
- Balanced Momentum View: Equal weighting of gains and losses reduces bias
- Versatility: Works across markets and timeframes
- Clear Signal Generation: Simple zero-line and divergence signals
- Less Noise Than Stochastic: More stable due to full-price-cycle consideration
Drawbacks
- Lagging Nature: Relies on historical data, so signals may come late
- False Signals in Choppy Markets: Whipsaws can occur during consolidation
- Not Standalone: Should be combined with trend filters or price action
CMO vs. Stochastic Indicator: Key Differences
While both are momentum oscillators, their calculations differ significantly:
- CMO: Uses net momentum (gains minus losses) across full cycles → smoother, more balanced
- Stochastic: Compares closing price to recent range → more sensitive to short-term swings
As a result, the CMO is less prone to false signals in volatile conditions, while Stochastic reacts faster but generates more noise.
Optimal Time Frame and Settings
The default 9-period setting works well for most traders. For longer-term strategies:
- Use on 4-hour or daily charts
- Pair with trending assets (e.g., major forex pairs or strong crypto trends)
Shorter settings (e.g., 5–7) increase sensitivity for scalping; longer settings (14–20) smooth out noise for swing trading.

Frequently Asked Questions (FAQ)
Q: Can the Chande Momentum Oscillator be used for cryptocurrency trading?
A: Yes. The CMO is effective in crypto markets due to their high volatility. Use it with higher timeframes to filter out noise.
Q: What does a CMO reading of +100 mean?
A: It indicates that all recent price changes were gains—extremely strong bullish momentum, often unsustainable.
Q: Is the CMO better than RSI?
A: Not necessarily "better," but more balanced. RSI emphasizes gains; CMO treats gains and losses equally, offering a neutral perspective.
Q: How do I avoid false signals with the CMO?
A: Combine it with trend filters like EMAs or MACD, and avoid trading against the dominant trend.
Q: Can I use the CMO for day trading?
A: Yes, especially on 1-hour and 4-hour charts. Adjust the period to 5–7 for increased sensitivity.
Q: Does the CMO work in ranging markets?
A: It can identify overbought/oversold levels in ranges, but divergence and zero-line crossovers are less reliable without a clear trend.
Final Thoughts
The Chande Momentum Oscillator offers a refined approach to measuring price momentum with mathematical balance and clarity. When used alongside trend-confirming tools like EMAs, it becomes a robust component of any technical trading system. While not immune to lag or false signals, its ability to detect divergence, gauge overbought/oversold conditions, and confirm trend direction makes it a valuable asset for traders seeking precision.
Remember: no indicator works in isolation. Integrate the CMO into a comprehensive strategy that includes risk management, confirmation signals, and market context for best results.
