Project mention: Does anyone know of a "zapper" like portfolio tracker that automatically calculates Profit/Loss? | /r/defi | 2023-12-11That already exists: https://rotki.com/
Project mention: EU suggests breaking up Google's ad business in preliminary antitrust ruling | news.ycombinator.com | 2023-06-14In a project I maintain on billing and payments[1], I had a link to Google Ads API. It was documenting how they had hard-limit budget, with notions like "capped actuals" and "monthly with rollover". The explanation was quite good so I keep it around to explain the concept, and why it was perfect for customers to avoid any surprises.
Then the URL[2] 404'd and the API disappeared. I couldn't find any references to a "BillingCap". I wondered why[3].
Now it makes sense: they got rid of budgets as you explained above. Everything's seems to be obfuscated behind a quite opaque Proposals/Deals[4] data structure now.

I recommend using RP2: it's a free, open-source, non-commercial, privacy-focused tax software that will track all your transactions and movements and generate the 8949 form. It's on Github: https://github.com/eprbell/rp2.
