All leveraged trades are imported as PnL data (profit and loss as a result of a closed position) provided by the exchange. Those PnL data are e.g. imported as transaction types "margin loss" and "margin profit". See this FAQ as well: How is Margin Loss Δ (delta) calculated ? (https://cointracking.freshdesk.com/a/solutions/articles/29000037668?lang=en)
And the exchanges have to provide those PnL data as we cannot calculate them on our own. So you can make them aware of those PnL data which are needed.
