Ask HN: What is a good tool for portfolio mgmt, investing, finance?

Hello HN,

I would like to know if you have any recommendations for different tools (open source or otherwise) that you use for personal portfolio management, finances, investing etc.

I would like a tool that protects your data but also gives you option to integrate with external tools if needed. Something that can be scripted to a certain extent would be most helpful. Having said that i would like to learn the capabilities and limitations of the best tools in the market and it can help me sway my thinking in different ways.
