TJ:
Through the years, AB's charting has
definitely improved but there is certainly room to grow. As you have
pointed out, the tools for doing just about anything in AFL have been
provided. However, I can assure you that much is beyond many either
because of coding ability and/or time availability.
You ask for comments so I'll throw out a number
that quickly come to mind. I'm sure this is not a complete list and
others undoubtedly have their own additions. In general, I view
AB's charting improvements in two categories - built-in functionality and
coding aids for custom charting.
In the built in area, I suggest the
following:
1. Increased available price styles,
particularly those requiring X-axis adjustment such as Point & Figure,
Renko, Equi-volume, etc. Metastock, Ensign and StockCharts are good
models.
2. Expand the functionality of
current charting tools to their full potential. Examples are warning and
Fibonacci lines for Pitchfork, internal and external Alternate Fibonacci Price
Projections (trend-counter trend), Fibonacci Time Retracements (internal,
external, and trend-counter trend). Dynamic Trader is a good
model.
3. Calendar day scaling (Gann
studies). Dynamic Trader is a good model.
4. Simple Fibonacci and standard
pattern (e.g., triangle and wedge) display (scanned or pivots chosen
by user). Market Warrior and Ensign are good models.
5. A variety of Gann studies,
including repeating price-time boxes with Gann angles (follow the price action)
and Pyrapoint. Gannalyst, Ensign and Dynamic Trader are good
models.
6. Independent font control for axis
and text.
In the coding area for custom charting I suggest
providing some "building blocks" that can be "included" in custom
charts.
A number of custom charts involve clicking on
specific bars in a manner similar to the way that the Pitchfork tool
works. This leads to some difficulties, including:
a. The built-in
charting tools provide a sharp cross pointer for choosing the desired
bar. However, the much coarser selection arrow is provided for the
same function with custom charts. This is a problem when many bars are on
the chart (i.e., longer times) that could be resolved by making the fine
pointer available for inclusion in codes.
b. Selecting
three points (e.g., DGL), as with the Pitchfork tool, involves
(at least that is how I do it) setting the range (to get BeginValue and
EndValue) and then clicking on the third point. The resulting chart has a
range marker at the first two points and the selector line at the third
point. Unlike the Pitchfork tool, if the selector line is moved
the chart changes. For this type of chart Pitchfork tool
functionality is desired. One way to go might be to provide an
AFL "building block(s)" that functions along the lines of the
Pitchfork tool (i.e., bars chosen by click, charted lines locked, and no visible
range marker or selector line on the plot). Another way is to provide this
type of plot as a built in. Dynamic Trader is a good
model.
c. Facilitate
locating the correct bar by providing a "building block" that
highlights the bar without clicking as the selector moves. This
feature could also be included as a built in. Dynamic Trader is a good
model.
2. Presently, plotted lines that
intersect the axis are bent instead of being terminated at the axis.
Mentioned software are good models.
3. Indicator pane size is unequal
when the number of panes exceeds 4. Mentioned software are good
models.

Subject: Re: [amibroker] 'Rule Based'
versus 'Discretionary' trading...
Hello,
Not wanting to hijack this thread but whenever I
ask
about some itemized list of what is exactly "weak" in AB charting,
I
don't receive any meaningful reply. I would really want to know
some
objective list instead of statements I heard on ET that
"charts are ugly"
which for me unfortunatelly means nothing,
considering the hunderds of ways
charts can be customized
according to user taste in AB.
Best
regards,
