CMO (Chande Momentum Oscillator)

The Chande Momentum Oscillator (CMO) is a technical momentum indicator developed by Tushar Chande that measures the momentum of price movements by calculating the difference between the sum of recent gains and the sum of recent losses. It oscillates between -100 and +100, helping traders identify overbought and oversold conditions, as well as trend strength and potential reversals.

Formula

CMO = 100 × ((Su - Sd) / (Su + Sd))
Where:
Su = Sum of gains over n periods
Sd = Sum of losses over n periods
n = typically 14 periods

How CMO Works

The CMO calculates momentum by comparing upward price movements to downward price movements over a specified period. Values above +50 indicate overbought conditions, while values below -50 indicate oversold conditions. The zero line acts as a signal line, with crossovers potentially indicating trend changes. The indicator's extreme readings can help identify potential price reversals, while its slope can indicate trend strength.

Trading Strategies Using CMO

Strategy Examples

  • Enter long positions when CMO crosses above -50 (oversold)
  • Enter short positions when CMO crosses below +50 (overbought)
  • Use zero-line crossovers for trend direction confirmation
  • Look for divergence between CMO and price for reversal signals
  • Combine with trend indicators for stronger trade signals

Support and Resistance Strategy

  • Use CMO levels as dynamic support/resistance zones
  • Look for price reactions at extreme CMO values (+50/-50)
  • Monitor CMO convergence with key price levels
  • Use CMO crossovers near support/resistance for confirmation
  • Combine with volume analysis at key levels

Trend Identification

  • Consistently positive CMO indicates strong uptrend
  • Consistently negative CMO indicates strong downtrend
  • CMO crossing zero line suggests potential trend change
  • Higher CMO peaks show strengthening uptrend momentum
  • Lower CMO troughs show strengthening downtrend momentum

Advantages and Limitations

Advantages

  • Clear overbought/oversold levels
  • Effective at identifying trend strength
  • Provides reliable divergence signals
  • Less prone to whipsaws than other oscillators
  • Works well in trending markets

Limitations

  • Can remain in extreme zones during strong trends
  • May generate false signals in choppy markets
  • Lagging indicator due to period calculations
  • Requires confirmation from other indicators
  • Less effective in ranging markets

Best Practices When Using CMO

  • Combine CMO signals with other technical indicators for confirmation
  • Use multiple timeframes to validate momentum trends
  • Wait for clear overbought/oversold signals rather than minor fluctuations
  • Consider overall market context when interpreting CMO signals
  • Look for divergences between price and CMO for potential reversals
  • Use CMO zero-line crossovers to confirm trend changes
  • Be cautious of false signals during ranging or choppy markets
  • Set appropriate stop-loss levels based on CMO and price action
  • Monitor extreme CMO readings (+/-50) for potential reversal points
  • Regularly review and adjust CMO period settings based on market conditions
