Hi,
I need some changes made to Chartsy and I am willing to pay.

I need the following changes:
1) Read favorites from database
2) Store/read chartFrame to database on close of chart (currently
serializes on program exit)

If interested, can you please contact me regard costs?

Thanks,
Steve

Hi everyone!

I've made Chartsy repository mirror on GitHub and reserved "chartsy"
organization name for possible future use while working on my derived
project.

Take a look please to:
http://github.com/chartsy/

At now I'm only admin member of this organization and its project and I want
to transfer admin rights and organization ownership to real developers.

Regards, coinfreak!

No documentation unfortunately. There are some very basic tutorials on the 
website. This is about all you can do in Chartsy right now unless you've got 
some decent development skills. Other things will come along in time where 
developers will provide "frameworks" for creating or altering or adding to the 
program. I'm not sure what's up next though.

Apologies for the late response to this. I've been VERY busy with my current 
job.

The fix actually is easy... use Netbeans 6.9.1. We haven't converted over to 7.0 
yet that Iknow of. Plus, the error says it's looking for hte 6.9.x build 
harness. Stick with 6.9.1 for now. I have both 6.9.1 and v7.0 on my machine at 
the moment. I haven't contributed to Chartsy since last October but I just 
haven't had a chance. I'll be finishing up the TA-Lib technical indicators 
integration when I can get back to it. I have the Japanese Candlestick 
recognition code to integrate.

Good luck. 6.9.1 should work for you.

Hi,

I am a new subscriber to this list.  Pulled down the source along with the new 
NetBeans 7.0.  When I try to build, I got the following error:

C:\projects\chartsy\trunk\Chartsy\build.xml:7: The following error occurred 
while executing this line:
C:\projects\chartsy\trunk\Chartsy\nbproject\build-impl.xml:41: Cannot find 
NetBeans build harness. 

Check that nbplatform.NetBeans_IDE_6.9_(Build_201006101454).netbeans.dest.dir 
and nbplatform.NetBeans_IDE_6.9_(Build_201006101454).harness.dir are defined. 

On a developer machine these are normally defined in 
C:\Users\johndoe\.netbeans\7.0\build.properties=C:\Users\johndoe\.netbeans\7.0/build.properties

but for automated builds you should pass these properties to Ant explicitly.

Any easy fix that exists?  thanks

Is there a forum where you discuss development changes or is this it?  I've
used forums in the past but never mailing lists.  I remember hearing about
mailing lists 20 years ago but I've actually never been on one or used one.
Before I submit any questions or write any code I want to make sure I'm in
the right place.

Thanks Vio. I will download 6.9.1 and continue the development. I worked my way 
through the JUnit issue with 7.0. It's a nasty issue with the JUnit integration 
into that baseline delivery for Netbeans. Not an easily solvable problem and not 
solvable in the GUI. If the issue persists in release 7.0. I can tell you guys 
how to overcome it. It's not a natural progression of logic. I had to find a way 
to fix it without changing our project file.

respectfully,
josh

Hi Josh,

We are still developing Chartsy in NetBeans 6.9.1.
The next version of Chartsy 1.5.0 will be developed on NetBeans 7.0, but 
there will be major changes.
For now you should continue to develop the TALib on NetBeans 6.9.1.

guys,

I just downloaded Netbeans 7.0 rc2 and when I go to do a clean and build on 
Chartsy I get:

C:\Program Files\NetBeans 7.0 RC2\harness\suite.xml:182: The following error 
occurred while executing this line:
C:\Program Files\NetBeans 7.0 RC2\harness\build.xml:171: No dependent module 
org.netbeans.libs.junit4

I tried downloading and installing (NBv6.9) org.netbeans.libs.junit4 and 
re-running the clean and build to no effect. I'm looking all over in my IDE for 
some way to set JUnit to "Global" but it's not coming up anywhere. I can't even 
find the dang thing except in my installed plugins but you can't do anything 
with it there. This is clearly an IDE thing and not a Chartsy thing. Is there 
something I need to manually edit that I don't know about? I shouldn't have to 
go and manually edit something knowing full well the edit might mess up Chartsy 
on your systems. What is the resolution to this problem? have you encountered 
this? I'm assuming you have already overcome this issue.

Hi all,

There is a small improvement I've been meaning to find the time to
implement. But I'm not  Java programmer, so I just thought I'd mention
it in case somebody else was up for it.

With the fibonnaci indicator, I want to be able to set my own fib
lines, and to set the colours for each line.

So, for instance, I'd want to be able to set a 85% retrace line, and
give it my own colour, say yellow. I'd like to make the 61.8% retrace
red and the 38.2% retrace green.

With the projection tool, I'd like to have the same ability. I'd like
to be able to set my own projection levels and colour them.

This ability should be application wide. So that every time I draw a
retrace it uses my preset colours. Then I can click on the individual
retracements and recolour them if I wish.

I did take a look at the code a few months back and it seemed
relatively clean. I'm willing to have a crack at it if nobody else is
interested.

Cheers,
Alex

All,

I'm back to coding chartsy starting this week. I will finish where I left off 
with the TA-Lib integration and I will do the candle indicators next. I will 
download the latest code tomorrow night.

I was thinking about how to efficiently use indicators in chartsy. It will be 
important most especially for the candle indicator calculations. I think we have 
a requirement that should read something like: "The chart shall update 
indicators only once at each new time bar." The goal is to allow candlesticks to 
update as needed but the indicators should only be calculated at the moment 
of each new candle being created. The logical flow is something like:

if (Not New Time Bar){
   update Timebar Data 
}
else //it's a new time bar so....
{
   update Timebar Data
   update indicator data
}

It's not meant to be beautiful code but it's meant to show the idea. This should 
be done because the indicator associated with any timebar is representative of 
the complete calculation up to that bar. This means that whatever activity that 
happens in that timebar is not calculated until that timebar ends and the new 
timebar opens. Then the resulting indicator calculation is performed and the 
result of all activity including the most recent timebar closure is represented 
above the current active timebar. the complete calculation of an indicator above 
any timebar is based on all the timebars before it only and does not include any 
activity from the timebar with which it is associated.

Knowing this, we can insure that indicator calculations only happen once at the 
beginning of the active timebar. I'm not sure Chartsy does this but I'm going to 
investigate it to see if this has been considered already. This will greatly 
enhance the ability of the AI framework (next on my list) to perform it's 
functions and calculations without worrying about chart performance, CPU usage, 
memory management, etc, etc. Some of the indicator calculations can be 
monstrous.

I look forward to contributing again!

respectfully,
Josh
Hello Chartsy crew,

Sorry I haven't been in contact. I've had some issues with my previous company 
not being able to stay in business so I was looking for another company to keep 
me employed. I have been picked up by Accenture now and am leading the 
engineering of a key piece of a cool new project (www.paywithisis.com). It has 
been keeping me quite busy and I haven't had a lot of time to put toward 
Chartsy. I'm hoping as I get into a "rhythm" on this project that I'll be able 
to spend some time on Chartsy at night or on the weekends. I still want to 
complete the TA-Lib integration. Apologies for leaving that half-way 
implemented. Also I will still be interested in building out the A.I. Framework 
that can be leveraged by developers. I'm thinking if my current work schedule 
becomes predictable and consistent that I can be back to building out Chartsy by 
late next month or May. I travel a lot for this job and it's early in 
development for this contract so my schedule and work duties are crazy right 
now.

I will stay in touch and hopefully before the summer I will be back to 
contributing to Chartsy.

Josh

Hi Laurentiu

I will try to use the new chart for awhile, to verify that there are no
other problems in it and that I got it right. When I'm done, I'll send you
my details.

Thanks for the help guys.

  Hi Alex,

We would appreciate if you can make the plugin available for everyone, 
of course.

Also, if you're interested in becoming a constant code contributor 
please give me your sf.net username and I will give you svn access (you 
also need to sign the CLA at the bottom of this page: 
http://www.chartsy.org/community).

If not, you can just send the code and we'll add it.

Alex,
First, "org.charty.macd" and "org.charty.ema" are mispelled. They are missing the "s" in chartsy. That's why they aren't valid packages.
Next, if you have created a module in Chartsy to build your chart, do the following:-Right click the Chartsy Project Module in the "Project" Panel.-Select "sources" in the left pane.-Your module should appear in the right pane in the long list of Chartsy modules. If not, select "add" and find your module. This should not be your problem though but covering all bases here.
for whatever reason, I've found on two occasions that a module (random) stops showing up in that list on my system. Not sure if it's something I'm doing when building/compiling/submitting or what but it seems rare and sporadic for now so I'm not worried. 
Now, if the above doesn't fix your problem, go into the Project panel again, got to Chartsy project, open the "modules" folder, and find your module. If you did the above, it's visible in the list in this folder.- double click your module and then scroll down/up in the project pane to where it is opened.- Right click your opened module and select "properties"- Select Libraries in the left pane- Select "Module Dependencies" tab in the right pane- you should see "Moving Average Convergence/Divergence" and "Exponential Moving Average" listed in the module dependencies. If not, add them via "Add Dependency."
Inside the Chartsy project, all modules are accessible only in so far as you identify them as dependencies. This is the Netbeans approach as well and it's a very solid approach to creating, protecting, and managing code. If none of this works, let us know.

Hi Viorel

How do I:
1. Make sure that EMA and MACD packages are included in project libraries (I've added them as non-api module dependencies in NetBeans. Is it enough?).

2. Make EMA and MACD public packages - How do I do that?

In addition, I've added your example code but NetBeans doesn't "see" org.charty.macd and org.charty.ema as valid packages.

Thank you for your help.

Hi Viorel!
Thank you so much for the help. I've tried to do this on my own and came up with something similar.

I now only have 2 questions:

1. I think that the more correct code would be:
if (emaDataset.getDataItem(i) != null && emaDataset.getDataItem(i-1) != null
                    && macdDataset.getDataItem(i) != null && macdDataset.getDataItem(i-1) != null)

                {
                    if (emaDataset.getCloseAt(i) > emaDataset.getCloseAt(i-1)                               && macdDataset.getCloseAt(i) > macdDataset.getCloseAt(i-1)  )

                        g.setColor(Color.GREEN);
                    else if (emaDataset.getCloseAt(i) < emaDataset.getCloseAt(i-1)                               && macdDataset.getCloseAt(i) < macdDataset.getCloseAt(i-1))

                        g.setColor(Color.RED);
                    else
                        g.setColor(Color.BLUE);
                }
2.  Should it just compile? I had a problem at home with compiling this module for some reason...

    You ca see that I copied the OHLC code.

    Note:

     - Make sure that EMA and MACD packages are included in your project
    libraries.

     - Make EMA and MACD public packages.

Hi Alex,

I'll send some screenshots on your email.

Best regards,

Hi Viorel

How do I:

1. Make sure that EMA and MACD packages are included in project libraries
(I've added them as non-api module dependencies in NetBeans. Is it enough?).
2. Make EMA and MACD public packages - How do I do that?

In addition, I've added your example code but NetBeans doesn't "see"
org.charty.macd and org.charty.ema as valid packages.

Thank you for your help.

Hi Alex,

1. My code was an example :). Make the changes that you need to 
implement the new chart.
2. Can you please send me the error text?

Best regards,
Viorel

Hi Viorel!

Thank you so much for the help. I've tried to do this on my own and came up
with something similar.

I now only have 2 questions:

1. I think that the more correct code would be:

if (emaDataset.getDataItem(i) != null && emaDataset.getDataItem(i-1) != null
                    && macdDataset.getDataItem(i) != null &&
macdDataset.getDataItem(i-1) != null)
                {
                    if (emaDataset.getCloseAt(i)
> emaDataset.getCloseAt(i-1)
                              && macdDataset.getCloseAt(i)
> macdDataset.getCloseAt(i-1)  )
                        g.setColor(Color.GREEN);
                    else if (emaDataset.getCloseAt(i)
< emaDataset.getCloseAt(i-1)
                              && macdDataset.getCloseAt(i)
< macdDataset.getCloseAt(i-1))
                        g.setColor(Color.RED);
                    else
                        g.setColor(Color.BLUE);
                }

2.  Should it just compile? I had a problem at home with compiling this
module for some reason...
