MACD
Divergence Forex Signal: How Reliable?
Some
traders regard MACD divergence as a Forex signal to enter a high probability
trade. They almost suggest you get straight in to a trade as soon as
you see MACD divergence.
Is this
Forex signal that reliable? To be fair, it certainly has a place in
a successful trader's kit of strategies, but as with any Forex signal,
there are certain precautions that have to be observed to make any
trade high probability.
At this
time there doesn't appear to be any Forex signal that offers anywhere
near a 100% success rate.
So if you
are tempted to trade on the basis of MACD divergence, what other factors
should you keep in mind?
MACD
Divergence Defined
First let's
just spell out exactly what is meant by MACD divergence.
MACD (Moving
Average Convergence Divergence) comes as a standard Forex signal on
all the main charting packages. Some show MACD by itself with two lines,
one a combination of a 12 and 26 Exponential Moving Average, and the
other line based on a 9 Exponential Moving Average.
Some charting
packages also include what is called a Histogram in the same charting
area as MACD. The histogram merely represents in a different way what
is happening between the two MACD lines as to market momentum. The
wider the gap between the MACD lines, the higher or lower the height
of the histogram bars.
To identify
MACD divergence, simply draw a line across the highs if MACD is above
the zero line, or draw a line across the lows if MACD is below the
zero line.
Now go to
the price action section of the chart, the candlesticks, and draw a
line across the highs directly above where the line is drawn on the
MACD highs, or draw a line across price lows directly above where the
line is drawn on MACD lows.
If they
are going in opposite directions you have MACD divergence. In other
words, when MACD is making lower highs and lower lows but price is
making higher highs and higher lows, this negative MACD divergence
forms a Forex signal indicating price could well start to drop.
If MACD
is making higher highs and higher lows but price is making lower highs
and lower lows, this positive MACD divergence forms a Forex signal
indicating price could well start to rise.

Divergence Precautions
Be aware
that MACD divergence on a smaller time frame is not so significant.
When it is seen on a 15 minute chart it may or may not be very important.
If seen
on a 60 minute, 4 hour, or daily chart, start doing more analysis.
If you see
MACD divergence on two or more of the higher time frames, then definitely
sit up and take notice and start looking for other factors to indicate
when price may react to the divergence.
This brings
us to a key point when trading MACD divergence as a Forex signal to
enter a trade. On a higher time frame, MACD divergence can be a fairly
reliable indicator of a change in price direction. However, the big
question is: WHEN?
Many traders
get caught out by entering a trade too soon when they see MACD divergence.
In many cases, price has still got some muscle to continue in the current
direction. The trader who has jumped in too soon can only stare at
the screen in dismay as price shoots through his stop taking him out.
How Can
This Scenario Be Avoided
Before pulling
the trigger when you see MACD divergence on the higher time frames,
be sure to look for other key Forex signals to confirm that the divergence
has really kicked in.
For example,
if you see a distinctive candle pattern such as a tweezer top or a
hanging man on the higher time frame it may appear price has topped
out and is now ready to move in the other direction.
If at the
same time the distinctive candle pattern is at a key level of previous
support or resistance, or at a pivot level, or a Fibonacci retracement
or extension level, you have added reason to believe this could well
be a turning point and put an entry order in at this level to get taken
in.
At the same
time, you will want to consult your trading calendar to make sure you
are not entering a trade near a significant Fundamental Announcement.
Even though the MACD divergence may kick in soon, the Fundamental Announcement
could cause a major spike in price and take out your stop.
So in
summary, is MACD divergence a high probability Forex signal?
Answer: By
itself NO!
How can
MACD divergence be used safely?
Answer: Check
to see if MACD divergence is seen on one or more higher time frame
charts such as the 60 minute, 4 hour, or daily.
Then look
for other Forex signals such as candle patterns, support or resistance
levels, or Fibonacci retracement extension levels.
In other
words, use MACD divergence as a confirmation Forex signal that you
are going in the right direction rather than a stand-alone Forex signal.
