MACD crossovers are the most-screened event in technical analysis. They are also lagging by construction — which is the whole point, and the whole limitation.
Moving Average Convergence Divergence is built from moving averages of price, and has three components:
A bullish crossover is the MACD line crossing above the signal line: short-term momentum has turned up relative to its own recent average. A bearish crossover is the reverse. Because both lines are built from moving averages, the cross always happens after the price move that caused it. MACD is a lagging indicator by design — it trades early warning for confirmation.
That trade-off is worth understanding rather than complaining about. A leading indicator gives you more signals, earlier, and more of them are wrong. A lagging one gives you fewer, later, and asks you to accept that you will never catch the exact turn.
Across 500+ pairs, MACD crossovers happen constantly — in choppy sideways markets they happen repeatedly on the same coin as the two lines tangle around each other. This is the classic failure mode, and it is why the raw crossover is best used as a starting filter rather than a complete one.
The usual refinements:
altscreenerai includes MACD Crossover, MACD Bullish Cross and MACD Bearish Cross as built-in conditions. A scan checks all 500+ pairs on your chosen candle size and returns those where the cross is present, which you can then stack with other conditions to narrow the list.
Crossovers are also one of the conditions you can attach an alert to, which suits them well: a cross is a discrete moment rather than a persistent state, so it is easy to miss by not looking at the right minute.
