1. On the main menu in the upper left corner, press 
to access the side menu.
2. Click Exchange billing.
On the top of the page, you can see your balance total in your local currency. It tells you how much cash in hand is missing or extra due to your exchange transactions.
The upper segment of the screen is dedicated to the Buy part of the Exchange and the lower segment is dedicated to the Sell part of the Exchange. In each segment, you have listed all the cryptocurrencies which had activity today, along with the sum total in your local currency.
If you add the totals from both segments together, you get the Balance total on top of the page.
3. You can also print the billing slip by clicking the blue printer icon in the upper right corner.
