Using pies to replicate ETFs?

Hi topher, thank you for the links to the ETF-replicating pies! I wonder how many others are doing this, as needing to avoid ETFs is a bit of a niche situation to be in.

Looks like some effort to set up, and then if the ETF weightings change you’d have to go in and type in the new weights.

Looks like there’s no public API really (Does Trading212 have an API?), let alone an API for setting the percentages in pies.

I think at a minimum I’d want to be able to upload a CSV with the desired tickers and percentages, may be even run a script to scrape my fav ETFs holdings and set the percentages.

And of course export the holdings for analysis in other tools.
