We recommend you add all transactions exactly as they actually took place 

This means you would not delete the Wallet deposits and withdrawals and only enter the trades, but you would ADD transactions to complete the existing transactions with an imaginary exchange.


You could name it "Private Exchange" (PE) for example. 


Now you enter the 

- OUT from the Wallet (included in Wallet imports), 

- the IN on the "PE", 

- the trade on the "PE", 

- the OUT from the "PE" and the 

- IN on the Wallet again (included in Wallet imports). 


This is the most detailed way of handling those transactions and you avoid reimport of deleted transactions
