Close real time charting with Qt 5 Python and ChartDirector

This is minute timeframe which is pretty close to real time. I will be teaching and improving this script in my upcoming LIVE Python intake. Sign up here below on a super discount!!

Yes in Python with simplicity!

To me this a game changer don’t you think?? Do remember that I have found a way to run Qt 5 Designer with Python in the last posting on this blog.

Live intake: GUI with local Python Django on VS Code or Pycharm vs C++ Qt or WxWidgets

A couple of details for you technical geeks out there who want to build an automated trading system. My Python scripts are getting crazy to manage so Ithere are better ways to manage them through a graphical user interface. I have 2 paths to choose which will my future live intake :

GUI with local Python Django on Visual Studio Code or Pycharm vs C++ Qt or WxWidgets

https://quantlabs.net/blog/2018/12/gui-python-django-vs-c-qt-wxwidgets/

The other track is with Qt 5 Designer with Python which I got working:

Qt5 Designer builder does exist for GUI file to convert into Python

https://quantlabs.net/blog/2018/12/qt5-designer-builder-does-exist-for-gui-file-to-convert-into-python/

Which path would you be interested in doing?

There are ways to enhance my GUI with Python. I will be applying this to my current course:

Python 3 Infrastructure Blocks with Crypto

A live intake  will be starting in early Jan 2019. This may be my only one I will ever do.

Let me know if you got questions on that.

This will be extremely limited to a few people to keep the quality of delivering content high.

Thanks Bryan

GUI with local Python Django on Visual Studio Code or Pycharm vs C++ Qt or WxWidgets

This was a mess to get a real time chart using Chart Director. To get a graphical user interface, I must this was turning into a real hassle with C++. Qt version 5 is still too restrictive on the run time licensing end. Also, I find their IDE Qt Creator is just a beast where I really don’t want to use it. I even tried local Python with some moderate success.

I then tried using the open source edition of the CodeLite IDE with wxWidgets, I have had moderate success with this combo. It seem to get running on a Mac is not worth pursuing as it is way too old.

I then thought of trying the latest PyCharm Pro edition with ChartDirector and Django. Oh man, this is thing is a beast , They assume my package manager with my Python interpreter version 3 was using pip. I am actually using pip3 but to change that was not possible. You would think this was easy by justing adding the local Python interpreter. Pycharm did not recognize my local Python 3.6 but only found 3.1. When i navigated to the Python 3.6 to choose within the creator of the project, it would finally rconginze all the local Python packages. It took forever to load. Complete crap and not easy to play. Plus they want me to pay for this thing as it for the Pro edition.  Forget it!

I then had some moderate success with Visual Studio Code. It is these URL that make it much more possible:

https://code.visualstudio.com/docs/python/tutorial-django

OMG! Half the tutorial actually worked. I can also say I have much better understanding and appreciation for this IDE. I see why people like it since I got it to work.

Then we can talk about Django. No no no. Working with this framework made we want to stop. This thing is really old. There must be an easier way to build a real time charting with Chart Director. There has to be.

QT open sourced a lot of new sh*t

And now a special message from someone on Skype:

QT open sourced a lot of new sh*t.

QT Charts.
Ain’t going there. Stick with GNUPLOT. Must be desperate times over there at QT makers. Thanks to someone who will not move off that evil software.

Qt 5 for Python dropped? C++ is only real option?

 

My view of Python with QT5:

 

Under QT 4, there was the separate Qt Designer where you could convert QML to Python with this utility:

 

pyuic4

 

http://askubuntu.com/questions/264037/how-to-use-qt-creator-with-python

 

That was my original vision to use but Qt 5 seems the standard.

 

From my understanding, it looks like this utility has been dropped under Qt 5. Also the Qt Designer has been folded into Qt Creator. As a result, Python has been abandoned in Qt 5.

There are some Python packages you can use with Qt 5 like PyQt or PySide. Both involve hand coding which is yucky for me. I even confirmed this theory by using searching on Google for ‘Qt 5 Python’ which only listed the above Python packages.

 

I like Rapid Application Development utilities like Visual Studio, Qt Creator, IBM Rational Rose, etc.  it is 2016 for frigging sakes! There are some open source utilities for Qt RAD development but they are pretty buggy so no go there.

 

Options for deployment with Qt 5.

 

After reading this book, Application Development Qt-Creator, the only options are Qt Creator for C++ or Qt Quick for QML (proprietary Javascript like for mobile development in Qt).

This Qt Quick seem very limited so that is not an option for mobile. Qt Creator with C++ is really the only option for RAD.

 

After this other book listed below, it is sort of useless as it only contains various projects done with Qt. Really? I could download many examples from online for free.

Hunting for good software libraries can be really challenging. You can win some and you can lose some. I was fortunate enough to find this ChartDirector which is an affordable commercial charting package which fits my needs for C++. Although Python does have some shortcomings, this potential stack may meet my needs for rapid application development in C++. Yes, here we go again with Qt. Ugh but it may end well.

 

Check out my quick video on this combination

Check that out here

 

So where do we go from here? Well, if Qt behaves itself and stays stable unlike previous versions, I may stick with this path. It also means I can rapidly start developing my components of all my strategies I want to get underway. As said, I hope it works out, so let’s hear a woo hoo!

 

I sometimes really hate architecting software like this but these are the challenges that we all face. I’m really hoping we have a winner finally. If it is, I can start putting on some private demos of this new trading system I’m working on.
