When entering a new transaction, the value of the asset can be set ("Edit Asset Value").

If the field is skipped, CoinTracking calculates the value of the asset using historical prices.

In the event that the buy and sell prices differ substantially, please edit the value of the asset on the 'Enter Coins' page.

Example (Screenshot is different):

The average price for 1 BTC [Sell] in FIAT is sometimes not the same price as 10 ETH [Buy] in average in FIAT value. The BTC has at this point of time for example an average value of 3200 USD and the ETH has an average value of 3100 USD only. This results in a spread. The spread should not be higher than 5% and can be viewed for all transactions on the Trade Prices page.
