If/Then Statements with Keltner Channels
by OI Staff
HAVING TROUBLE PRINTING?
Even the best trade setups occasionally turn sour. A recent article described
how nested Keltner channels can be used to determine breakouts and set targets,
but they can also confirm when
Keltner-based trades turn sour. They allow the
construction of if/then statements that set specific goals for preserving or
invalidating a breakout signal.
An example occurred Thursday and Friday, April 21 and 22. A breakout signal was
invalidated. The OEX had been building a broadening formation at the bottom of
its drop off the April 12 high, alternating rallies with steep descents.
Thursday had been a rally day. The OEX had risen to test its 200-sma, the 38.2%
of its fall from the April 12 high and nested Keltner resistance.
Climbing above and maintaining the 200-sma into the close would have been a coup
for bulls, and so it might have been assumed that a drive into that average
would occur near the close. It did, creating a new Keltner channel breakout
signal in the process.
Note: Background and settings for the nested Keltner channels discussed in this
article can be found in the Sunday, March 20 Traders Corner article.
15-Minute Chart of the OEX for Thursday, April 21:
Experienced traders might have found the breakout suspicious. Reasons included
the already stated notion that the late-day push had been intended to close the
OEX back above its violated 200-sma. In addition, the drive stopped short of the
50% retracement of the plummet
off the April 12 high and had taken on the look
of a bearish rising wedge.
A suspicious trader might have wanted to know Thursday evening what would be
needed to invalidate that breakout signal the next morning. The breakout above
that black channel had suggested the OEX would move to the outer boundary of the
next wider channel, so a 15-minute close beneath the black channel line would be
needed to invalidate the signal. Thursday night, a trader would have been able

period candle below the Keltner line currently at 553.29, then it will have
invalidated the breakout signal. The upside target would be erased. At the open,
the Keltner line might move somewhat: hence, the "currently at" part of the

that blue channel turns up, the OEX is moving higher. When it turns down, the
OEX is moving lower. When it flattens, the movement is losing momentum. If OEX
closes had been above the red basis line, a close below it would tend to flatten
the blue channel. If closes had been below the basis line, a close back above it
would tend to flatten the blue channel. A trader looking at that chart Thursday
evening would know that a 15-minute close beneath that red line would tend to
flatten the blue channel. It would be a signal that the upward movement might be

first 15-minute candle corroborated the impression that Thursday's breakout
was not to be trusted. Friday, April 22, the OEX eventually dropped to a low of
546.88 before bouncing. Trading had been volatile for days, with breakouts
untrustworthy, but the ability to construct an if/then statement based on
Keltner evidence had given traders concrete levels to watch. They knew when a
breakout play was being invalidated and its target erased.
working trades see short-term retracements against the position. Knowing
when a trade still works despite those to-be-expected retracements proves just
as important as determining when trades turn sour. Keltner-based if/then
statements can be used for that purpose, too.
Annotated Daily Chart of the TRAN:
On the chart above, the red
central basis line of the small blue channel shows
up in bold to make it more visible. Continued daily closes beneath that basis
line kept the TRAN's smallest Keltner channel pointed down and the TRAN
traveling lower within that channel. The if/then statement that market watchers
might have constructed was as follows: As long as the TRAN produces daily closes
beneath the red line, then the TRAN remains vulnerable to declines toward the
lower black channel line.
statement could be constructed. If the TRAN began producing daily closes
above the red line, then the TRAN was trying to steady and the downside thrust
might be losing momentum. Bears in transportation stocks might have been alerted
to a deceleration in downside momentum. This did happen, but the TRAN was to
switch gears again the next day, April 22, and then resume its downward course.
A special situation exists when if/then statements do not work as well. This
when the Keltner channels flatten and line up, one within the other. This
equilibrium state occurs when prices consolidate in a tight range over a
prolonged period. The central basis lines of the various channels converge, and
appear to be strong support or resistance. Traders might be tempted to construct
if/then statements that sound like the following: If prices close above/below
the mid-channel level, then the upside/downside target is at the next outer
