Convergence is also a disparity between the chart and the MACD histogram, but in the opposite direction: the chart moves down and indicates that the price is falling, and the indicator is pointed up and indicates an increase in price.
In convergence, as in divergence, the trend may reverse and the price may start to rise after a fall.
Convergence, like divergence, is an inaccurate and weak signal. Use it as a way to help confirm other, stronger signals.
