Hi Uenal,
first of all I want to say that your ABtool is an interesting
project. I took a brief look at it yesterday after purchasing
Amibroker RT. I have developed an experimental plug-in DLL
extension to Metastock, which calls via JNI the Java 2 virtual
machine. The intention was however a totally different one than
ABtool's objective: Rather than providing a set of external commands
to make programming in Metastock's formula language easier, the
idea was to create an external environment within which indicators
can be _entirely_ implemented in Java using all the nice stuff such
as the collection classes, object orientation etc.
But back to the topic before digressing too much: The fact that you
are able to implement the xxStudyGetNext() function in the next
ABtool version shows that it is somehow possible to obtain all study
IDs for the studies drawn by the user.
I have skimmed over the file adk.html included with the ADK and
understand that AFL plug-ins have the ability to call internal
Amibroker functions via the CallFunction() method of the site
interface. But I'd like to know through which functions one can
obtain things like the study and chart IDs for all the studies drawn
by the user for a specific stock.
Further, it would be very useful and open up interesting
possibilities if it was possible for plug-in developers to get
information on every study the user has drawn in the charts for a
specific stock, without being required to know in advance details
such as chartID and studyID.
With information on a study, I do not mean just the array of points
returned by study() function, but also information such as StartX,
StartY, EndX, EndY, StartBarNum, EndBarNum, LeftExtend, RightExtend.
Also, Amibroker's concept of multiple chart sheets is very useful,
but right now the chartID is a mess. It is well possible that I
have not yet really understood the chartID concept. It would be
very useful if for any given chart pane one can obtain the
information like the number of the chart sheet the chart pane is
assigned to. Is this already possible? If so, it would be able
for an external plug-in to issue an alert to the user as follows:
"Ticker uvwx: Check chart sheet #3 for a trendline violation.".
In short, what I propose (and I hope TJ listens if this is not yet
possible with AB) is the introduction of methods through which for
any given stock a plug-in can inquire about all studies the user has
drawn and then get information on these studies (without being
required to have any knowledge of chartIDs and studyIDs in advance).
It wouldn't be any problem if this information got only provided at
a lower level like the site interface, this could even be an
advantage. With tools like ABtool, this functionality could be
made available at AFL level in a user-friendly form, but I'm
personally interested in getting the information directly from
Amibroker without having to use rely on other plugins.
best regards,
Wolfgang
