With Fixed Leverage the Slave trade size is fixed and is a defined function of a wished leverage that the trade has to have on the Slave account. The Slave lot size does not depend on the Master trade size in that case.
Below is the formula used to compute the slave order size:
Slave order size = Slave "Account Size" x "Fixed Leverage" Value
When using the “Fixed Leverage” method, the system will compute the order size to place on the Slave account defining the leverage that the new position has to have regarding the account size of the Slave account.
