Alright, I see. Thank you.
If it’s not already obvious, I’m quite naïve about trading. Given that most (if
not all?) historical price records seem to have been retroactively updated for
all cumulative splits (ie https://finance.yahoo.com/quote/NVDA/ shows the
2024-02-14 closing price as 73.90 USD), is there any reason not to just update
the original transaction in my ledger?
