This fee is a percentage of the net profit you generate in your account by copying trades from a specific master account. For example, if you earn a net profit of $100 in your account, and the Performance Fee is 20%, then you would pay $20 as a Performance Fee.
This fee is charged at the end of a certain period, whether daily, weekly, or monthly. The charging period starts from the day you subscribe.
In summary, Performance Fees are a portion of your earnings that you pay as a fee for using an investment account and achieving good results.
