Carrying on from Tim's recent discussion, which is also relevant to
your chart example.
In your example they recommend drawing a line under the 'pivots'.
Theoretically this plots a classic trend but in practice iti s not so
easy because the pivots don't play the game by lining up nicely along
the line. Typically the slope (monentum) of the 'pivot to pivot' line
changes througout the wave (note that I use my own system for wave
analysis ... sorry I won't publish my core methods that I still use ..
especially if they are original work).
There are also other problems with plotting a trendline from low to low
or high to high e.g. once some retracement starts to occur then some
lows or highs have to be 'missed' to retain the integrity of the
sraight line but using ValueWhen(higher low OR lower high,N) can give
you something precise to work with, including ROC.
IMO the term 'Pivot' is interchangeable with Peak/Trough etc ..
sometimes, in my code, I use both terms to mean the same thing.
As per my comments to Tim, I have some old code laying around ... not
complete and perhaps not the best but it gives you another avenue of
thought (while I am not using it at the moment I found it a worthwhile
subject of study and the fact I am not using it is not a negative
assessment of its value).
Note - all of my examples were written to use as visual tools only -
they contain a look forward component so they aren't suitable for
backtesting (they can be recoded for BT) ... a few incomplete examples
(AFAIK all that I have left) ..... it is basically my own stuff,
especially the idea of MajorPeaks which are the macro patterns (they
correspond to a higher timeframe).
Written for AB 4.9 in my early AB days (pretty basic stuff).
Incomplete examples ... use variations to achieve other results
including similar to the TS example.
Haven't used them for a long time OR checked them recently so no
guarantees as to their accuracy.
I probably haven't even backtested many or any of them.... I am not
really an algorithmic trader ... I just use AB for reasearching and
thinking about strategies etc.
My idea of a peak/trough is based on three bars with the central bar
either higher or lower.
I did write other versions and consider variations but I think that
code is gone.
One of the issues in writing code for a peak/trough is identifying when
two bars have equal highs ... what to do about that is personal
choice ... I did have some solutions ... it looks like some of the code
may include some of that stuff ... not sure if it is good or not.
The examples are biased to the long side because I tend to work the
code out in one direction first and only code the short side later.
