TradingView and Arithmos are often grouped together as "investing tools". They aren't really competitors. They sit on either side of a workflow.

FAQ
Do I need a TradingView subscription to use Arithmos?
No. Arithmos uses TradingView's free embed widgets for charts on individual holding pages. A paid TradingView account isn't required.
Can Arithmos export my index to TradingView as a watchlist?
We export to broker-friendly formats (CSV, Trading 212 Pie, Fidelity Basket). A direct TradingView watchlist export is on the roadmap. For now, the CSV holdings file imports cleanly into a TradingView watchlist.
