I posted this in r/learnmath but I'm not sure if no one is there, no cares or no one knows...

Anyway, I hope this is easy for someone, but basically the title says it all. I would like to express the following as a mathematical expression: "The Sum of Time does not change" I have come up with: ΣtΔ = 0 or: Σt ≠ Δ But really, I have no idea what I'm doing. Is there a proper way to represent that mathematically? Thanks!

I have been investing for some time now with a style that follows Buffet / Munger. It has served me well.

However, it disappoints me to no end that there are no tools (that I can find) that serve fundamental inclined investors. Everything I discovered seems to be focused on 'trading' with every 'technical' tool in the book.

So I have decided to write my own analysis software (I'm a retired developer) for my own use, however not necessarily exclusively.

The problem I am having is that I would like to see listed companies financials (quarterly preferably; also dividends, dates etc would be nice as well) but am having trouble locating a suitable data source. Surely this must exist somewhere
