The performance fee in copy trading can be calculated using one of the following methods:

1. Percentage of Net Profit: This can be based on:

- The sum of Realized PnL and Floating PnL.

- Only Realized PnL.

- The sum of Realized PnL and negative Floating PnL.

Additionally, when calculating net profit under any of these methods, the trade fees paid can be considered as a loss on the subscribed investment account.

2. High-Water Mark Principle: The performance fee is only charged on the net profit increment, meaning it is payable only if the current performance exceeds the previous highest net profit.

Example 1: Performance Fee without Trade Fee Consideration

If the fee is based on the sum of Realized PnL and Floating PnL, and trade fees are excluded:

Performance fee = (Current Total PnL - Previous Total PnL) * Fee%/100

- Current Total PnL: The total of Realized PnL and Floating PnL at the fee payment moment for positions copied from a specific master account.

- Previous Total PnL: The sum of Realized PnL and Floating PnL at the last successful fee payment.

- Fee%: The agreed performance fee percentage.

The performance fee applies only if Current Total PnL exceeds Previous Total PnL.

Example 2: Performance Fee Considering Trade Fees as Loss

If the fee is based on the sum of Realized PnL and Floating PnL, with trade fees deducted:

Performance fee = ((Current Total PnL - Paid trade fee) - Previous Total PnL) * Fee%/100

- Current Total PnL: Same as above.

- Paid Trade Fee: The total of the trade fees incurred.

- Previous Total PnL: As defined above.

The performance fee is charged only if ( Current Total PnL - Paid Trade Fee ) is greater than Previous Total PnL.
