A TRADE transaction takes place when you trade an amount of a cryptocurrency with a different amount of another cryptocurrency, for example trading ETH for BTC.
If the transaction didn't take place on one of the sources you automatically connected to CryptoBooks, you can manually add it in order to have your accountability correct.
These are the few necessary steps to perform (written description below the video!):
Click on the Transazioni tab
Click on the icon Manual Transactions +
Select Trade
Choose the category of the transaction from the drop-down menu
Insert date and time of the transaction
Select the currency you sent and its amount
Select the currency you received and its amount
Insert currency and amount of the fee
Click on Add Transaction
