Here's another example: 2020-06-02 * "Mining reward of 0.05 BTC" Assets:Ledger:BTC 0.05 BTC Income:Mining:USD
$ bean-price -vn price-fetch-test.beancount INFO : Using price cache at "/tmp/bean-price.cache" (with indefinite expiration) INFO : Processing at date: 2023-08-08 INFO : Loading "price-fetch-test.beancount" BTC /USD @ latest [ beanprice.sources.yahoo(BTC-USD) ] None of the transactions I enter seem to cause bean-price to fetch anything but @latest. Is there some annotation I need to be putting on my transactions to say "hey, price is needed here" ?
