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.
