MACD

The function returns the difference between a fast and slow moving average based on the same PRICE.

When the fast period moving average crosses above or crosses below the slow period moving average, a signal is generated. Once the lines cross, it becomes important to look at the distance between them. The MACD function returns that difference.

When the fast period moving average is above the slow period moving average, the MACD is positive and when it is below the slow period moving average the MACD is negative.
