The MACD is a trend following
momentum indicator that shows the relationship between three moving averages
of prices.
This method can be used for any time frame. It could be 5 minute bars, 15
minutes bars or daily bars. Many traders will also trade in multiple time
frames using a longer time frame for trend, and the shorter period for entry
and exit.
The MACD is the difference between a 26-day and 12-day exponential moving
average. A 9 period exponential moving average, called the signal (or
trigger) line is plotted on top of the MACD to show buy/sell
opportunities. On the charts below, the MACD line is the green colored
line, and the trailing, slower moving line is the signal line. Some
technical analysis programs will show the MACD as a histogram bar.
There are three popular ways to use the MACD: crossovers,
overbought/oversold conditions, and divergences.
The most common use is as a crossover method. Using this interpretation,
the trading rule is to sell when the MACD falls below its signal line.
Similarly, a buy signal occurs when the MACD rises above its signal line. It
is also popular to buy/sell when the MACD goes above/below zero.
Some traders will use MACD as an overbought and oversold indicator. When
using the indicator in this manner, when the shorter moving average pulls
away dramatically from the longer moving average (i.e., the MACD rises), it
is likely that the security price is overextending and will soon return to
more realistic levels. MACD overbought and oversold conditions vary from
security to security.
The other way some traders use MACD is to spot divergences from an
anticipated movement. Since there are no indicators or patterns that work
all the time, reactions against the anticipated move can signal a major
move. A bearish divergence occurs when the MACD is making new lows while
prices fail to reach new lows. A bullish divergence occurs when the MACD is
making new highs while prices fail to reach new highs. Both of these
divergences are most significant when they occur at relatively
overbought/oversold levels.
I like to combine this indicator with some kind of breakout pattern.
Lets look at Microsoft Corp. (NASDAQ:
MSFT).
Stocks dont go straight up or straight down.
There are thrusts up and then they lose momentum and drop down. Many times
it is like taking 3 steps forward, then 2 steps back.
The MACD indicator can signal a loss of strength and help a trader plan an
exit.
MSFT has moved up nicely over the past few days from a base.
The question for a trader is now, when do I exit and take my profit?
The MACD is turning and about to give a sell signal.
If MSFT opens down in the morning, I would exit the trade.
If MSFT opens up, let your profits run and move up your stop to the 73 �
area.
