This is a technical indicator that measures moving average convergence/divergence and provides a measurement of the intensity of the trading of a specific stock. It can provide early clues to trend continuation or reversal. The MACD indicator uses three exponential moving averages: a short or fast average, a long or slow average, and an average of the difference between the short and long averages. When the MACD line is rising, the implications are positive for prices: If the indicator is less than zero, the price is potentially bullish. If the indicator is greater than zero, the price is actually bullish. When the MACD line is falling, the implications are negative for prices: If the indicator is less than zero, the price is actually bearish. If the indicator is greater than zero, the price is potentially bearish.The signal line can be used to determine the entry or exit point. The signal line is a moving average of the MACD line. When signal line crosses MACD line and both lines are up, it is a buy signal. When signal line crosses MACD line and both lines are down, it is a sell signal.
