Bullish divergence is a technical analysis term that indicates a potential bullish reversal in a financial market. It occurs when the price of a security forms lower lows, while a technical indicator, such as the Relative Strength Index (RSI), forms higher lows. This divergence between the price and the indicator often precedes a reversal from a downtrend to an uptrend.
Key Elements of Bullish Divergence
Price Action
In a bullish divergence, the price of a security continues to decline, creating a series of lower lows. This downward trend in price represents bearish market sentiment.
Technical Indicators
Simultaneously, an oscillator or momentum indicator, like the RSI, Moving Average Convergence Divergence (MACD), or stochastic oscillator, forms higher lows. The discrepancy between the indicator and the price hints at a weakening bearish momentum and a potential bullish reversal.
Example of Bullish Divergence
For instance, consider a stock with the following observed price and RSI patterns over a period:
1- Date 1: Price = $50, RSI = 30 (Low)
2- Date 2: Price = $45, RSI = 35 (Higher Low)
3- Date 3: Price = $40, RSI = 40 (Higher Low)
Although the stock price falls from $50 to $40, the RSI increases from 30 to 40, signaling bullish divergence.
Historical Context and Applicability
Historical Context
Bullish divergence has long been used by traders and analysts to predict potential market reversals. The concept stems from the broader field of momentum analysis in technical trading, which has roots in early 20th-century financial market studies. Analysts like Charles Dow and Ralph Nelson Elliott contributed significantly to the development of these ideas.
Applicability in Trading
Traders use bullish divergence as a signal to identify buying opportunities. By spotting divergence early, traders can potentially capitalize on major market reversals or trend changes.
Types of Bullish Divergence
Regular Bullish Divergence
Occurs as described, with price forming lower lows and the indicator forming higher lows.
Hidden Bullish Divergence
Occurs when the price forms higher lows while the indicator forms lower lows. This type typically indicates a potential continuation of an uptrend rather than a reversal.
Special Considerations
False Signals
Like all technical indicators, bullish divergence is not foolproof and may generate false signals, especially in highly volatile markets. Traders often combine it with other technical tools, such as trend lines, volume indicators, and moving averages, to confirm signals.
Timeframes
The effectiveness of bullish divergence can vary across different timeframes. It’s generally more reliable on longer-term charts (e.g., daily or weekly) compared to shorter-term intraday charts.
Comparisons and Related Terms
Bullish vs. Bearish Divergence
- Bullish Divergence: Indicates potential upward reversal.
- Bearish Divergence: Indicates potential downward reversal, occurring when the price forms higher highs while the indicator forms lower highs.
Convergence
Convergence, the opposite of divergence, occurs when the price and the indicator move in the same direction, confirming the current trend.

Summary
Bullish divergence is a pivotal concept in technical analysis, acting as a precursor to potential bullish reversals in markets.
