Prices tend to consolidate periodically during
an uptrending move prior to continuing the
trend or changing direction. The indicators
highlight a price consolidation when the ADX
falls, while the MACD remains near or above its zero line. This pattern often occurs following a
confirming pattern, as the chart of Bank of
America Corp. (BAC) in Figure 4 illustrates.
Both indicators rose during the price uptrend
in December 2000 and January 2001. Both
indicators fell as price declined in February
2001. But the ADX continued to decline, while
MACD remained at or above its zero line as price
entered a trading range consolidation in March
and April. Once prices resumed their upmove in
May, both indicators once again began to rise.
SOME
OBSERVATIONS
• ADX: The ADX can be
confusing because it is
interpreted differently
from other indicators.
Most indicators move up
when prices rise, and
they fall when prices
decline. As seen in the
chart of Toys “R” Us (TOY) (Figure 5), that was
not necessarily the case with the ADX.
At point A the ADX was rising while price
moved down. The ADX pulled back slightly at
point B as prices rose. However, at point C the
ADX rose in conjunction with prices. The ADX
declined between points C and D, while price
moved sideways before resuming the uptrend
indicated by point D. The ADX dip into point E
paralleled a price decline during June. But instead
of a continuation of the preceding uptrend, the
next ADX rise at point F was met with a further
decline in price. The moral? Don’t try to secondguess
price direction with the ADX.
• MACD: Even the venerable MACD misleads
us at times. Often, we forget the MACD is
basically a momentum indicator, so it does not
always accurately reflect price movement either.
Figure 6 displays an example with AT&T (T).
In addition to the ADX and MACD in the upper
panels, I plotted a 13-unit simple moving average
of price on the chart. The 13-unit moving average
tends to correspond with the MACD solid line
crossing above and below its dotted trigger line
when the MACD is accurately tracking price.
The combination can help
traders stay on the right
side of the market and
increase the probability of
successful trading results.
At point 1, the MACD solid line rose above its trigger line,
which reflected the upmove in price. At point 2 the MACD
crossed below its dotted line, following price to the downside.
However, the MACD rise above its trigger line at point 3 was
not joined by rising prices or an upsloping moving average.
The MACD rose because downward momentum pressure had
diminished as prices slowed their downward descent.
• Indicator combo: As the charts show, both the MACD and
the ADX register their signals after the start of a price move,
with the ADX slower to respond than the MACD. That means
the indicator combination will not pinpoint tops and bottoms.
However, traders can expect the ADX–MACD combination to
identify and capture part of a trending move. More important,
it can help traders stay on the right side of the market and
increase the probability of successful trading results.
