I suggest you to register an account at
AltPocket.io; It's a portfolio that automatically pulls all your trades from some exchanges (including Bittrex) and shows your open investments.
E.g: If you buy 1 LTC for 0.0105 BTC, your profile at AltPocket will show an open LTC investment.
If the Litecoin price goes to 0.012 BTC, the portfolio will show that your investment made you a profit of 0.0015 BTC.
or if the price goes down to 0.009 BTC, the portfolio will show that your investment made you lose 0.0015 BTC.
When you close your investment by selling your 1 LTC, your profile will show your overall profit, net worth, and old investments.
