Trading for a Living
When the slope of MACD-Histogram moves in the same direction as prices, the trend is safe. When the slope of MACD-Histogram moves in a direction opposite to that of prices, the health of the trend is questioned. It is best to trade in the direction of the slope of MACD-Histogram because it shows whether bulls or bears dominate the market.
The slope of MACD-Histogram is more important than its position above or below the centerline. The best sell signals are given when MACD-Histogram is above its centerline but its slope turns down, showing that bulls have become exhausted. The best buy signals occur when MACD-Histogram is below its centerline but its slope turns up, showing that bears have become exhausted.
