MACD zero-line cross
The MACD line itself crossing above zero — the 12-day average overtaking the 26-day.
The signal-line cross fires early and often; the zero cross is the slower, sterner version, because MACD above zero means the fast average is now above the slow one outright. It confirms a trend change rather than anticipating one. Rare on any single day, and the names that fire it with price already above the 50-day are usually several weeks into a turn that has further to run.
