Hi Dario,
I hold an Unlimited Licence and I have some issues..
ALargeOrangeCat has a point ,I am running in the same issue...and i am mostly using the Relaized / Unrealized Gains TAB
When we (the users)  liquidate position and then start a new one , the software doesn't show correct info. It should know that we started over and not take into account the previous price to calculate an average . It is important to know the correct average price in case we want to short sell a coin for a buy-back at a lower price.

I use your service to keep track of more than 25 coins where I update (buy and sell) positions very often .
Other example I can give you:
I buyed STRAT at an average price of .0030 BTC and kept it  and after some time STRAT was .0020 BTC and buyed X ammount and after a few days , it went to .0024 and I sold the X amount taking profit ... Now I see REALIZED LOSS of 2 BTC on STRAT and the Gain from the X amount was 1 BTC.
1 more example:
I made 30 BTC profit on ETH and it was displayed as Realized Gain , then buyed some more and got stuck with it at 0.11...yesterday I made a quick trade and buyed and sold ETH for some profit ,now the balance shows lower Realized Gain and lower average purchase price, but the old ETH position stayed intact .

You should do something with the Algorithm to "recognize" these trades .
I always trade and import using Exchanger's API and refresh the (UN)Realized Gains page every 5-10 minutes so i can see how I am standing and when to take profit .
Also, ANS rebranded to NEO and it doesn't get updated anymore....You should Merge ANS with NEO

Thanks ,
Victor
