Number of units of asset owned
Amount of asset owned x Current Price
For cryptocurrencies, the price and thus the market value are determined by the source of the price selected which can be changed. The price is taken directly from the exchange selected and converted to your local fiat currency using the following steps:
Price is taken directly from the exchange. Let's take an example here of Ethereum (ETH) with Binance as the exchange and ETH/BTC as the source pair.
This price in ETH is converted to USD using the BTC/USD global average rate in Delta.
USD is converted to your local fiat currency using the appropriate Forex rates or to BTC and ETH using their respective global average prices in Delta.
You can tap the Market Value to toggle the currency between your local fiat currency and the quote currency of the pair selected. In the above example you can toggle the Basic Metrics between your local fiat currency and BTC.
Total Profit/Loss is the sum of all unrealized gains and realized gains. Simply put it is equal to:
Market Value + Sum of all proceeds (from sells) - Sum of all costs (from purchases)
Avg. Buy Price / Sell Price:
This is the weighted average of all the buy prices or sell prices. For example if you have two Buy transactions, one for $1000 and the other for $2000 with amounts of 5 and 10 respectively, the average buy price would be $1666:
(5 x 1000 + 2000 x 10) / 15
This is simply the total number of transactions for this asset in this particular portfolio.
METRICS OF EACH TRANSACTION
Buy Price / Sell Price
Price is taken directly as entered by you when adding the transaction or as imported from an exchange API. If the price is in BTC or ETH, it is converted to USD (or your local fiat) using the global average rate of BTC or ETH.
This is simply the net amount bought (after fees). For example if an order to buy 1 ETH is executed and has 0.01 ETH as fee then the amount bought shows 0.99.
Cost (incl. fee) / Proceeds (after fees):
This is the total cost of the transaction including fees in case of a buy transaction and the total proceeds (value of the sold amount) after deducting fees.
Worth and Delta:
Worth = Amount bought in that transaction x Current Price
Delta = (Worth - Cost) x 100 / Cost
