Maybe this Python package open source pytqtgraph could be useful for high speed charting for trading system?
This is read only. I am having problems finding something decent for open source trading for high speed trading. I also am getting tired of maintaining a Windows system with antivirus (a necessity in itself) that hampers the performance of this system.
Here are some videos to showcase the speed of this library in real time . Maybe worth looking at?

NOTE: There seem to be other packages including VISPY and PyOpenGL
