[GNC] Apparent Miscalculation

[John Ralls]

Eric,

Where you went astray in answering before was second-guessing my question: I asked you to report on specific entries in the price database. As I expected, you found the problem when you finally looked where I was trying to point you.

The reason that it was a problem is that GnuCash looks for a direct price before trying for indirect ones, so if it finds a direct price no matter how old that's what it will use.

Regards,
John Ralls

We need to find the sources of those inputs and they're most likely in the pricedb. The questions I asked are a start to that process; unfortunately your answers don't completely answer them. Please try again.

The "base currency" I use in my accounts is GBP (£) but I have some sub-accounts that are denominated in Euros (€). I attach a screen shot of part of my chart of accounts (the two columns of numbers are headed "Present(GBP)" and "Total"). The sub-sub-account "Eric ISA (ii) Shares-Euro" is a placeholder of currency Euro within a parent sub-account in currency GBP, itself under Assets also in GBP. The pertinent line is the first one of the screen shot; the Total is shown as €14805.44 (which is a correct calculation based on the numbers of shares and their values) but this number appears to be converted to £15824.56. This is obviously wrong as the exchange rate is €1 = £0.8966. Also the conversions of the individual shares to GBPs are also in error - but, interestingly, the implied Euro/GBP exchange rates are different (1.19 for Airbus, 0.76 for Deutsche Post and 0.95 for SAP). (The share prices and the exchange rate were all obtained through the "Get Quotes" feature and were confirmed by web searches.) If this were a general problem I'm sure it would have caused quite a flurry of messages so I can only assume that, somehow, I've screwed up somewhere (not unusual!) but I can't find where it is. If any one can point me to my error I'd appreciate it. For completeness I'm running GnuCash 3.8 with Finance::Quote 1.49 on Ubuntu 20.04 (Frankly, I can't see that having any bearing on this problem. But what do I know?) Take care, keep well

What are the latest prices, including currencies, dates, and amounts? What are the GBP->EUR and EUR->GBP exchange rates for each of the dates of those stock prices and what is the latest of each?
