Fixed Lot: The Slave trade size is fixed and is defined in advance for each trade no matter the Equity, Balance or Free Margin of both Slave and Master accounts.
When using the “Fixed Lot” method, whatever the Master trade size is, each trade placed on the Slave account will use the defined value as the trade size, no matter the Equity, Balance or Free Margin of both Slave and Master accounts.
Below the formula used to compute the slave order size:
The “Fixed Lot” value could be any positive or negative value, the system will round up to the closest volume incremental step for the traded instrument. A negative value will reverse the order side.
