Bug ID: 440745
Summary: Update EUR/BTC price online does not work
Product: kmymoney
Version: 5.1.2
Platform: Other
OS: Other
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kmymoney-devel@kde.org
Reporter: t...@marshall.name
Target Milestone: ---
SUMMARY
KMyMoney does not retrieve the correct value of EUR/BTC when updating for a
single date (which uses fx-rate.net).
STEPS TO REPRODUCE
1. Select the menu Tools => Update Stock and Currency Prices
2. Select the currency pair EUR > BTC
3. Click the button "Update Selected"
OBSERVED RESULT
Fetching URL https://fx-rate.net/EUR/BTC...
Identifier found: 'EUR/BTC'
Price found: '2.664' (2.664)
Date found: 'Sun Aug 8 2021'
Price for EUR > BTC updated (ID EUR BTC)
EXPECTED RESULT
Fetching URL https://fx-rate.net/EUR/BTC...
Identifier found: 'EUR/BTC'
Price found: '2.664e-5' (0.00002664)
Date found: 'Sun Aug 8 2021'
Price for EUR > BTC updated (ID EUR BTC)
SOFTWARE/OS VERSIONS
Windows: Windows 10 Home 20H2
ADDITIONAL INFORMATION
I am using KMyMoney version 5.1.2-772e77894.
For EUR/BTC, fx-rate.net returns a number in scientific notation. The regex
configuration that extracts this number is ([,\d+\.]+). I made a simple change
to ([,\d+\.e-]+), then re-ran the STEPS TO REPRODUCE and KMyMoney displayed
"Price found: '2.664e-5' (2.664e-05)" in the output. However, KMyMoney did not
use this value to update the price history of the currency.
Updating a range of prices also does not work (which uses stooq.com). I will
submit a formal bug report if you want; however, it's easy to reproduce it.
Fixing these bugs will allow the tracking of cryptocurrencies in KMyMoney and
would be a very useful capability.
