MACD
There are three ways we will suggest you can use MACD for determining trends.
- MACD Zero Line
- MACD Crossover
- MACD Combination
MACD Zero Line
If the MACD line is above the zero line, you are bullish; if it is below the zero line you are bearish.

This is a weekly chart of the S&P 500 stock index. Apart from three periods (circled in green), the MACD stays above or below the zero
line for a very prolonged period.
The trend is bullish if the leading MACD line (red line) is above the zero line (black horizontal line)
The trend is bearish if the leading MACD line is below the zero line
MACD Crossover
If the MACD line (red leading line) is above the signal line (green line) you are bullish; if it is below the signal line you are bearish.
This method will suit shorter term trading as opposed to longer term trading because the fluctuations from uptrend to downtrend and uptrend
again will be far more frequent than using the MACD zero line.
MACD Combination
Using both methods just previously discussed, we can combine them to create the following rules.
If the MACD is above the zero line, and the MACD line is above the signal line we are bullish; if the MACD is below the zero line and the MACD
line is below the signal line we are bearish.
In the following chart and in the lower pane, the red circles indicate bullish points, where the MACD is above zero and above its signal line
(red line is above the green line). The black arrows indicate where the MACD line crossed back below the signal line, and although still being
above the zero line on all five occasions, it gives a neutral reading; neither bullish nor bearish. Once again this method will suit shorter term
trading as opposed to longer term trading.
