In fact, for shares, 3 dates can be interesting:
1- The date and time when the shares have been bought. To be able to compute
the price.
2- The date when the shares have been bought. To have an estimation of the
shares value at the beginning.
3- Today. To have the current estimation of the shares value.

Skrooge displays something true: the current value of your shared date after
date...
... but I can understand that is not what you want.
In the "Unit" page, you can have the value of the share date after date.
This is not what you want too.
If I well understand, you would like to have: The history values of your
shares.
This history can be modified due to the number of shares or its value.
Skrooge is not able to display that.

Hi, I can not sum up the shares because I don't have guarantee that all
operations of the report are in the same unit. I don't know how to sum apples
and bananas. That's why, all operations are computed in primary unit (€) and
then mathematical operations can be done.
My first feeling is that the "Report" page is too generic to be able to cover
your request. I will think about "how to give you the expected report" and come
back to you with a proposal.
Regards.
