Momentum Position Trading With The MACD
When the market breaks out of a trading
channel, either rising above resistance or dropping below
support, use the momentum technique with the MACD.
This is generally a position trade, lasting several days or
even a month.
While you’ll pay a small overnight renewal fee (with most
brokers) to keep the trade active, these trades generally bring
in enough pips to make holding the position well worth your
while.
Moving Average Convergence/Divergence
(MACD) is a popular indicator that works well in momentum
markets. MACD (pronounced mac-d) plots three different
exponential moving averages, and displays them as two lines of
different colors that criss-cross atop the chart itself or
within the window below it. One line is the MACD itself; the
other is called the signal or trigger line.
The MACD also plots a histogram, which is a
sort of bar chart in the window below the currency pair’s price
chart. On the MACD histogram, there is a line that signals the
zero point, called the centerline, and the bars of its chart
rise and fall above and below that centerline like a wave. The
histogram illustrates the difference between the MACD line and
its signal line; when they cross each other, the histogram will
read zero.
If your software platform wants you to set the configuration
of the MACD, the most popular settings are 12 and 26 for the
indicator itself and 9 for the signal line. Experiment to find
what works best for you and your own trading style.
Like the RSI, MACD can indicate when a currency pair is
overbought or oversold. There’s no specific number to indicate
this, but when the lines of the histogram get really long,
that’s a good hint that a reversal could be near.
Again like the RSI, MACD can indicate divergence. When the
price reaches a new high or low but the MACD line doesn’t, that
could mean the momentum is weakening. Again, a reversal could
be near.
The technique
When the MACD crosses its signal line, that’s an entry signal
in the direction the MACD line is going. If it falls below its
signal line, look to see if a short trade is feasible; if it
rises above it, go long. This signal is considered especially
strong if, shortly after the crossover happens, the price of
the currency pair breaks above resistance or below support;
that could signal a big move.
Be aware that the MACD is a lagging indicator, so its
signals won’t call the absolute highs and lows for you. That’s
why it’s not helpful in a range-bound market: if you base your
entry points only on the MACD, by the time the indicator
catches up to the current price, the price may have risen or
fallen so far within the channel that there’s no longer enough
of a trade left to be profitable.
When using the MACD in a momentum market, where price has
broken through support or resistance and is reaching new highs
or lows, the MACD signals may start showing divergence,
indicating the trend is weakening when perhaps it really isn’t.
In that situation, watch the price chart itself, and compare
what it is telling you to what the indicators show.
For example, let’s say the GBP/USD has broken out above
resistance and is reaching new highs. The MACD signaled the
break by crossing over its trigger line, but as the price
continues to rise, the MACD doesn’t reach new highs, indicating
divergence, and you wonder if the trend is weakening.
Meanwhile, the price continues to rise.
Should you bail out? No. Watch the
chart.
As the GBP/USD continues to rise, it will fluctuate in
short- and intermediate term trends, going down a bit then
rising again. This is called market jitters, or swing lows (if
the currency pair was falling, they would be called swing
highs). Don’t let it bother you; it’s perfectly normal.
Notice that each new swing low is higher than the one
before. The market doesn’t swing down so much that the
long-term trend changes; it just retraces itself for a while,
then resumes its climb. It looks rather like someone dribbling
a basketball up a hill, each dribble higher than the one
before. (You do, of course, have your stop set far enough away
that the swings don’t trigger it and kick you out of a
profitable trade. Hopefully your broker offers a trailing stop,
so it rises to follow as the price goes up, locking in your
profits.)
Wait for that pattern to change. When a swing low goes lower
than the previous one, that’s the bail-out point. Close your
trade, then sit back and calculate your profits.
