Bitrue doesn't currently allow you to export trading history from their website, so you will need to open up a support ticket requesting your full trading history.
Open up a support ticket by choosing Submit a request

Need Trading History
Transaction History Report
I am currently trying to complete my taxes and need a spreadsheet detailing my full trading history on my account.
Submit your support request and wait for their team to give you the file.
Make sure that you have Bitrue selected as an exchange in Step 1, then navigate to the Bitrue tab in Step 2. Upload the trade history file that you received from their support team.
