Haven't used it.
I was listed on their Users-List back in 1998, when the Instantaneous TL was first mailed.
In an attempt to write the ITL for the use in Metastock, I only stumbled (at that time) on
my inabillity to "get it right" (among other stuff it uses the FFT, eg and that's at least
how I interpreted that mail). The MetaStock problems with FFT and my ITL attempt were
explained "a few mails ago"(000224) and at that time of publishing of the ITL-mail, lag of
time etc. and de-listing from that group did not help either to continue with my ITL creation
attempts. MESA98 also came with dll's that could then be called upon by user in the program.
I have only seen a short demo of the program, and found its interface very poor(MESA98).
But the ITL sure is intreging. Moreover, the way John Ehlers described it in the mail,
was super interesting. The way some lister got cracking at it in Excel, was informative too.
One of the fellow User-List subscribers, Don Kraska (S&C i believe), at one stage had
John Ehlers to slightly revise the ITL setup on a minor issue. Can't remember if he'd agreed.
I believe there are 2 websites now : mesasoftware.com and mesa-software.com

To MESA Users Group:
Here is a set of new indicators that you can program yourselves. The
first of these indicators I call an INSTANTANEOUS TRENDLINE. It works
because it completely removes the dominant cycle from a smoothing average.
For the mathematically inclined, the Fourier Transform of a rectangular
window (formed by a simiple average) is a Sin(X)/X distribution. The
objective is to place the first null of this distribution exactly at the
dominant cycle. For the intuitively inclined, what we are doing is taking
a simple average over the full dominant cycle period. In such an average,
there are as many sample points above the midpoint as below the midpoint
with the result that the sum of all these sample points is zero.
OK, so all we have to do to get an Instantaneous Trendline is to take a
simple average whose length is exactly the period of the dominant cycle.
For those of you who have TradeStation and MESA96, you just insert the dc
variable for the length of the simple moving average. For those of you who
have MetaStock or other toolbox packages, you just have to estimate the
length of the dominant cycle and insert that estimate as your moving
average period. Of course, this estimate is fixed across your entire
screen, but the dominant cycle length can be varying. So watch out for
that problem.
The next indicator is created by taking a moving average over half the
period of a dominant cycle. In this case, the amplitude of the dominant
cycle is attenuated by exactly 2/PI. Our objective is to restore the full
amplitude of the cyclic portion. So we take this latest moving average,
subtract the "Instantaneous Trendline", multiple the difference by PI/2
(1.57 approximately), and then add the Instantaneous trendline back. Since
the lag of a moving average is about half the moving average window length,
this modified half dominant cycle moving average will still lag the realy
cyclic swing by a quarter cycle.
Now, when we look at these two moving averages, we can make two
assessments. First, we now solve the age-old problem of what is the
trendline. We have create an adaptive trendline. Secondly, we can see the
cyclic swing relative to this trendline so that we can assess the amplitude
of the cyclic movement. If this cyclic amplitude is not several times that
average daily bar range, then getting an entry and exit for a profitable
cyclic move becomes a crapshoot. In other words, the signal to noise ratio
is so low that even though we have identified a good cycle, it is not large
enough to trade profitably without relying on an intraday fill.
Good Trading!!!
John
