MACD Bullish Crossover Alerts
A MACD bullish crossover — when the MACD line rises above the signal line — signals a shift in momentum from bearish to bullish. It's most powerful when it occurs below zero (confirming a trend reversal) or after a pullback in an uptrend.

How MACD Bullish Crossover Alerts Work
The MACD (Moving Average Convergence Divergence) indicator measures the relationship between two exponential moving averages (typically 12-day and 26-day). The MACD line is the difference between them; the signal line is a 9-day EMA of the MACD line.
A bullish crossover happens when the MACD line crosses above the signal line, indicating that short-term momentum is accelerating relative to the medium term. Below-zero crossovers (where both lines are negative) are especially significant — they signal potential trend reversals from downtrends.
Stock Alarm Pro detects MACD crossovers in real time and sends push notifications as soon as the crossover condition is met during market hours. Use MACD crossover alerts alongside RSI and volume data to filter high-conviction setups from noise.

Frequently Asked Questions
- What is the difference between a MACD crossover above and below zero?
- A crossover above zero means both MACD and signal lines are positive — confirming an uptrend. A crossover below zero (where the crossover happens while both lines are negative) signals a potential reversal from a downtrend. Below-zero crossovers are considered stronger reversal signals.
- How does MACD differ from RSI?
- RSI measures price momentum on a fixed 0–100 scale with overbought/oversold zones. MACD measures the relationship between two moving averages and has no fixed range — it highlights trend changes and momentum shifts. They complement each other well.
- How often do MACD crossovers occur?
- On a daily chart, MACD crossovers occur on average every 2–6 weeks for most stocks. In trending markets they are less frequent; in choppy markets they can whipsaw more often. Weekly chart MACD crossovers are slower but more reliable.
- Can I alert on MACD histogram direction instead of crossovers?
- Stock Alarm Pro currently alerts on MACD line crossovers. The histogram (MACD minus signal) changes direction before a crossover — follow the histogram visually on the technicals page for earlier signals.
