I was away for a loooong time. It seems due to the API change all my tools are obselete now.
I was wondering if there is a tool that scans the transactions and calculates an average price for the commodities you purchase?
Purchase 1: 10000 ItemX at 5 isk per
Purchase2: 20000 ItemX at 4 isk per
Warehouse: ItemX amount 30000 @ 4.33 isk per
I was using evecost.eu for this which tracked the transactions and let me manually subtract any amount that i use.
