yes!


I'm aware of the study() function.

The problem with the current study() function is that in order to use
this function, knowledge of specific chartIDs and studyIDs is 
required.

This works well for a handful of stocks, but it is not a practical 
approach to write a generalized exploration or alert manager 
application.

For example, in the chart for MSFT, the user might have drawn 7
up-trendlines (some for long-term, some for short-term trends),
whereas in the chart for IBM he might have have drawn only
2 up-trendlines.   In addition, the user might have drawn the
trendlines for MSFT in two separate chart panes, one chart
pane plotted with a linear y axis, the other chart pane plotted
with a semi-log y axis.

For a generalized exploration that checks for trendline violations, 
it would be necessary to obtain all pairs of <chartID,studyID> for
the studies drawn for a specific stock.  Moreover, it could be
necessary to obtain directly the attributes/properties of a specific 
line study such as StartX, StartY, EndX, EndY.

As mentioned in my previous post, such information would at best
be provided at the low-level plug-in interface. Plug-in developers 
could make use of this functionality and incorporate it in 
user-friendly functions available in AFL.
