I would like to make a free open-source C++ application for both Linux and Windows which will create live stock market charts (i.e. they’re refreshed frequently).
Please could you give me some pointers on these issues:
- What should I use as the data source? Are there free services I can implement? I would like to use the same or similar information as companies like Google.
- I’m not sure what GUI toolkit would be best to use, is there one which has charting built in, or would I need to use a specialized library for this?
Some things to note:
- This is my first attempt at both cross-platform C++ development, and a GUI application for Linux.
- I’m based in the UK, so I’d like to use data sources that provide information for the London stock exchange (LON) as well as NASDAQ, etc.
