I have been hacking around with algorithmic trading as a hobby project to build my data analysis skills, coding skills, and learn more about financial markets. As part of this project I am interested in developing a web interface to monitor my portfolio. I have done some homework but would like to hear the community's thoughts, as there seems to be much more focus on backtesting and other analysis in the open-source community (for good reason).
I am hoping to build something (in python) that could be used to monitor a real-money portfolio, as well as be used as a project on my CV that would not be laughed out of a reasonably sophisticated trading shop. My general timeframe per trade will be 5 minutes or longer, so nothing most folks would refer to as HFT.
What features* should an investment-grade algo dashboard include? Are there any examples of note?
Clarification: I am not just looking for visualizations, but also standard/key metrics. For instance, I would expect to see some measures of value at risk, returns over key periods, etc.
