I am looking on how to handle portfolio over a range of date.
A portfolio is defined by the positions it points to and doesn’t points to the actual data they position store.
Following is the state of portfolio on day X
And on day Y (Y>X)
Here on date Y , all i have to do is change the values in the position.
But then on portfolio side , its not marked that a change happened on that date.
So the only way to see when all a portfolio changed over a date would be checking all the position 's history versions.
Which looks like a bit hectic to me.What is the recommended way of operation here ?
On a related issue , if we look at an older version of portfolio (in web UI), though the older version of portfolio is shown , the version (and data) of positions shown is the latest. Which i feel is a bug.
