First of all, good work! I like this software.
Second, some comments:
The indicator editor is very intuitive and interesting. However, it seems that not every indicator is easy to draw in the editor, e.g. KDJ …. So it will be very helpful to implement some common indicators in JStock.
I also notice that many users give similar suggestions. So maybe it should be given higher priority :)
Or maybe Jstock can try "plugin" way. If some one develop new functions or new indicators, they can develop a plugin for people to install. If some plugins are very popular, they can be included in the next version of JStock.
We hear you!
Please refer what are upcoming development plan for JStock.
