English to Italian Bus/Financial Law: Contract(s) Trading Authorization

Hi everyone! here is the context:

30 % of the amount generated from one period to the next, based upon the net equity positions at the end of each period minus the highest net equity position reached since the opening of the account (high watermark), excluding ***day to day administrative adjustments*** to the account, deposits, withdrawals, rollover premiums etc… Should this amount be negative, no amount is due to the owner of the Master Account.

Grazie in anticipo!
