Bug ID: 380187
Summary: Shares always use the current rate/value
Product: skrooge
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: guillaume.deb...@gmail.com
Reporter: bernhard+...@scheirle.de
CC: steph...@mankowski.fr
Target Milestone: ---
Skrooge Version: 2.8.1
The 'Amount' column of operations in an investment account (using not the
default unit as unit) gets computed with the current (exchange) rate.
But the amount should be computed with the exchange rate of the date of the
operation.
This wrong amount also has a huge impact on reports.
It is not possible to track the development/value of an investment.
Compare the two attached screen-shots of the same investement (Every year a
small amount of shares get sold).
In KMyMoney you can see the value of the investement for each year [No
operations entered for 2009-2012].
Skrooge displays values which have nothing to do with reality.
It reflects the sold shares but does not take into account that a single share
changes its value.

I don't understand why you compute the total from the EUR values.
Why not simply sum up the shares and than multiply with the exchange rate?:
INITIAL TOTAL = 100 ZARCHF (= 100 EUR)
-10 ZARCHF (= -20 EUR)
NEW TOTAL = 90 ZARCHF = 180 EUR (computed via 90 * 2 and NOT 100 - 20)
Other programs (like KMyMoney) also manage to calculate a correct total and
display per operation the corresponding EUR value (at that time).
