At the top of your Profit/Loss view, the graph line represents the variation of the combined balance you’ve had during the time period you’ve selected - the last day, week, month, six months, year, or for all time.
How is it calculated?
Your combined balance changes based on the variation of the crypto price and on your transactions (deposits, withdrawals).
For example, when you deposit in your local currency, your combined balance will increase by the exact value of your deposit. The same happens when you withdraw from your local currency wallet. If you own cryptocurrencies, the value of your combined balance is also influenced by the price of the cryptocurrencies you own.
When you select certain points in time on your graph line (on the web, hover your cursor over the graph line to see more detail; and on mobile, press and hold your finger over the graph to see the same) a tooltip displays your combined balance totals for a specific date, as well as the time the snapshot was captured.
