|
|
|
|
```bash
|
|
pricehist fetch ecb EUR/AUD -s 2021-01-01 -o gnucash-sql | sqlite3 Accounts.gnucash
|
|
pricehist fetch ecb EUR/AUD -s 2021-01-01 -o gnucash-sql | mysql -u username -p -D databasename
|
|
pricehist fetch ecb EUR/AUD -s 2021-01-01 -o gnucash-sql | psql -U username -d databasename -v ON_ERROR_STOP=1
|
|
```
|
|
|
|
## Design choices
|
|
|
|
To keep things simple, `pricehist` provides only univariate time series of
|
|
daily historical prices. It doesn't provide other types of market, financial or
|
|
economic data, real-time prices, or other temporal resolutions. Multiple or
|
|
multivariate series require multiple invocations.
|
|
|
|
## Alternatives
|
|
|
|
Beancount's [`bean-price`](https://beancount.github.io/docs/fetching_prices_in_beancount.html)
|
|
tool fetches historical prices and addresses other workflow concerns in a
|
|
Beancount-specific manner.
|
|
|
|
The GnuCash wiki documents [wrapper scripts](https://wiki.gnucash.org/wiki/Stocks/get_prices)
|
|
for the [Finance::QuoteHist](https://metacpan.org/pod/Finance::QuoteHist) Perl
|
|
module.
