Because when i decide to sell for euro i would like to not show it in the total value anymore.
Sum Coins: 1.458,84 €
Sum Currencies: 500,00 €
Total Value: 1.958,84 €
Hey, the "Total Value" without currencies is exactly the "Sum Coins" value.
So you can just use this one if you're not interested in your currencies.
As an alternative you could add a withdrawal of 500 EUR to equal both values.
But the first solution is much easier.
Yes, the API import will always re-import all trades once they have been deleted.
I have this "time-period" feature already on my todo list.
But there is a workaround for now:
Go to the Enter Coins page, and select all your older trades you don't want (use the SHIFT key to select multiple entries at a time).
Click now on the "edit" button and set the "buy amount", "sell amount" and "fee amount" to 0.
This will overwrite all selected trades with 0 and because they are not deleted, they will not be re-imported or overwritten by the Polo API.
Best, Dario
