The reversal of a long consolidation
In the
previous article we emphasized that our primary goal with the MIDAS method is
to provide a means of characterizing price
behavior which is based on underlying realities rather than ad hoc
empiricism or numerology. This is fundamentally a scientific question, quite apart from the tactical
matter of utilizing such knowledge for trading advantage. In a broad sense we
may thus distinguish between what might
be called the scientific and the engineering aspects of MIDAS, where the former
encompasses the quantitave
"laws" which give rise to the S/R hierarchies, and the latter refers
to practical trading rules and techniques based on this understanding.
We made a
start on the engineering side by showing how the "foothills" could be
recognized and used as a low risk/high reward
entry point for intermediate term long positions. Here the window of
opportunity is quite wide in time since the foothills have a typical time scale of the order of months
and it is merely a matter of scrutinizing a sufficiently large number of stock
charts to find some likely candidates.
Once one gets used to spotting foothill behavior in the gentle undulations of
conventional bar charts, a few hours
each month leafing through a book of daily basis stock charts will suffice to
identify at least 30 or 40 such candidates
justifying further analysis using quantitative MIDAS methods.
The
reversal of a long consolidation or bear leg within a primary bull move, via a
bounce from S1 or S2 provides an even better
trading opportunity since the gains come much more quickly and the price
objectives are well defined. (At a minimum one expects to reach the nearest resistance level,
usually an R1 or R2. If this is penetrated then the next objective is the
previous high.) The window of
opportunity is however much shorter, typically a few days to a few weeks. Furthermore,
for any given stock there may only be
one or two such opportunities per year.
Thus while
MIDAS methods could be used on single stocks to determine good entry points for
long positions suggested on fundamental
(as opposed to technical) grounds, the trader will monitor many stocks ( of the
order of hundreds ) in order that
sufficient opportunities will be found to keep capital off the
sidelines. To facilitate the application of MIDAS to a large universe of stocks in real time, we have developed some
interesting techniques for compressing a fairly complete MIDAS characterization
of a given stock into a few ascii
characters.
This is
illustrated in the first figure which contains a Midas chart of EMC Corp. By
now this should be so familiar that no commentary is required. (Although one cannot refrain from
marvelling at how well the trend reversals are anticipated!). Above the chart is a single line of ascii characters and
its associated legend.
Note the
line of dashes bounded by an "l" (for low) and an "h" (for
high). This represents a price range extending from 2.63 to 23.38 in this case. The capital
"S" denotes the relative position within this interval of the primary
support level S1. The corresponding
positions of the secondary and tertiary supports are indicated by lower case
"s"'s. The asterisk is the average price for that particular day. Thus this so-called MIDAS Profile shows
the number of S/R levels (resistance levels use "r" instead of
"s"), their relationship to
each other and to the latest price, as well as where they all stand in relation
to the high and low for the historical
period in question.
Two
further features may be simply added to convey even more information. If a
given S/R level is particularly well "validated" (i.e. it has successfully predicted several
trend reversals with little porosity), we can underline the symbol as we have
done for S2 (or it could be made
boldface if the software and printer permit). In addition, if the asterisk
should happen to coincide with an S or
an s, we can replace it with a >> or a > (or << or <)
respectively. This has the effect of immediately calling attention to the
fact that the price is at an S/R level
and perhaps ready to bounce.
In
addition to this pseudo-graphical technique, we generate the three ratios
defined in the graph. OBVR is an obv ratio measuring how far the obv has retreated from its peak value. The closer
OBVR is to unity, the more bullish the outlook. DIST (standing for "distension") is a normalized
measure of how close the latest price is to S1. SPRD (for "spread")
measures the volatility of the stock
over the historical period of study.
Trading
rules can be developed based on these three quantities. For example, one
can only enter long positions when OBVR
exceeds a certain threshold, DIST is less than another threshold (i.e. close to
S1 and ready to bounce) and SPRD is
greater than a third threshold (to weed out stocks that are not volatile enough
to have a sufficient potential reward).
Now a neural network trained on these inputs might have some hope of success!
For a
group of stocks, one would then generate each day a table such as that shown in
the second figure. With a little practise one
can thereby review a few hundred stocks in a matter of minutes to identify
interesting opportunities.
