In the world of technical trading, few concepts are as powerful—and often misunderstood—as divergences. At their core, bullish divergences and bearish reversal signals offer traders a window into shifting market momentum, revealing when trends may be losing steam or preparing for a dramatic turnaround. These signals, derived from oscillator indicators, help investors anticipate changes in price direction before they become evident in the charts.
While trend-following tools excel in identifying long-term movements, oscillators shine in detecting short-term shifts—especially when their behavior diverges from price action. Understanding these dynamics can significantly enhance trading decisions, from timing entries and exits to managing risk more effectively.

Understanding Divergence in Technical Analysis
Divergence occurs when the price of an asset moves in the opposite direction of a technical indicator—typically an oscillator like the Relative Strength Index (RSI), MACD, or Stochastic Oscillator. This mismatch suggests that underlying momentum is weakening, even if price continues moving in the same direction.
There are two primary types of divergence:
- Bullish divergence: Price makes a new low, but the oscillator fails to confirm it with a corresponding low. This indicates diminishing selling pressure and hints at a potential upward reversal.
- Bearish divergence: Price reaches a new high, yet the oscillator records a lower peak. This reflects weakening buying momentum and may signal an impending downturn.
These signals are not standalone guarantees of reversal but serve as early warnings—clues that the market’s internal strength is shifting beneath the surface.
Types of Divergences: Class A, B, and C
Not all divergences carry equal weight. Traders classify them into three categories based on strength and reliability: Class A, Class B, and Class C.
Class A Divergences – The Strongest Signals
Class A bearish divergence forms when price hits a fresh high, but the oscillator peaks at a lower level than during the previous rally. This shows that despite higher prices, momentum is fading—often preceding a sharp decline.
Conversely, a Class A bullish divergence appears when price drops to a new low, but the oscillator forms a higher low. This suggests sellers are losing control, and buyers may soon push prices upward aggressively.
These are considered the most reliable signals and often coincide with significant trend reversals.
Class B Divergences – Warning Signs of Exhaustion
A Class B bearish divergence occurs in a double-top pattern: price forms two similar highs, but the oscillator shows a lower second peak. This indicates weakening bullish momentum.
Similarly, a Class B bullish divergence emerges in a double-bottom setup where price records two comparable lows, but the oscillator traces a higher second bottom—suggesting growing buyer interest.
While less powerful than Class A, these patterns still warrant attention, especially when confirmed by other technical factors like volume or support/resistance levels.
Class C Divergences – Signs of Market Stagnation
Class C bearish divergence happens when price reaches a new high, but the oscillator matches its prior peak exactly. Likewise, Class C bullish divergence occurs when price hits a new low while the oscillator forms an identical bottom.
These patterns suggest equilibrium between buyers and sellers—neither side gaining ground. Rather than signaling a strong reversal, they often reflect market stagnation or consolidation.

The Role of Momentum and Rate of Change
To fully grasp divergence, one must understand the concepts of momentum and rate of change (RoC)—two closely related indicators that measure the speed of price movement.
Measuring Market Speed with Rate of Change (RoC)
The Rate of Change indicator compares the current closing price to a previous close from X days ago:
RoC = Today’s Closing Price / Closing Price X Days Ago
- If RoC > 1 → upward momentum
- If RoC < 1 → downward momentum
- If RoC = 1 → no change
By plotting RoC values over time, traders can visualize whether momentum is accelerating or decelerating—critical for anticipating reversals.
Calculating Momentum
Momentum is calculated slightly differently:
Momentum = Today’s Closing Price – Closing Price X Days Ago
A rising momentum line indicates increasing bullish sentiment; a falling line reflects growing bearishness. When price climbs but momentum declines, it creates a bearish divergence—a red flag for overextended rallies.
Conversely, when price falls but momentum rises, it generates a bullish divergence, suggesting sellers are exhausted and buyers may soon take charge.
These subtle shifts often precede visible price reversals by several candles—giving alert traders a strategic edge.
Practical Applications for Traders
Using divergences effectively requires more than just recognition—it demands context.
- Timeframe selection: Shorter timeframes (e.g., 4-hour or daily charts) tend to yield clearer divergence signals. While longer timeframes provide stronger confirmation, intraday noise can obscure patterns on lower intervals.
- Indicator choice: RSI and MACD are among the most popular oscillators for spotting divergence due to their sensitivity and clarity.
Confirmation tools: Always pair divergence signals with other technical elements:
- Support and resistance levels
- Candlestick reversal patterns (e.g., doji, engulfing)
- Volume spikes
For example, a bullish divergence near a key support zone with rising volume increases the probability of a successful long trade.
Frequently Asked Questions (FAQ)
Q: Can divergences predict exact reversal points?
A: No single indicator can pinpoint exact turning points. Divergences highlight potential reversals by showing weakening momentum. They work best when combined with other confirmation tools.
Q: Are bullish and bearish divergences equally reliable?
A: Statistically, bullish divergences tend to have higher success rates in strong uptrending markets, while bearish ones perform better in downtrends. However, Class A divergences remain the most dependable regardless of market bias.
Q: How many periods should I use for momentum or RoC calculations?
A: Common settings range from 10 to 14 periods. Shorter windows increase sensitivity but may generate false signals; longer periods smooth data but lag behind real-time action.
Q: Can I automate divergence detection?
A: Yes—many trading platforms offer scripts or alerts for automatic divergence detection. However, manual verification is recommended to avoid false positives caused by minor wicks or erratic price spikes.
Q: Do divergences work in sideways markets?
A: In ranging markets, divergences may occur frequently but lack directional follow-through. They are most effective at the extremes of consolidation zones—near clear support or resistance.
Final Thoughts: Mastering Divergence for Smarter Trading
Divergence analysis bridges the gap between price action and underlying market psychology. By monitoring how momentum shifts relative to price, traders gain insight into the balance between fear and greed—an advantage few retail investors fully exploit.
Whether identifying a Class A bullish divergence at a critical support level or spotting a bearish reversal signal after an extended rally, these tools empower traders to act ahead of the crowd.
