Fixed Multiplier: The Slave trade size is simply a multiplier applied to the Master trade size no matter the Equity, Balance or Free Margin of both Slave and Master accounts.
When using the “Fixed Multiplier” method, the system will multiply the master trade size by the defined value and place the corresponding order on the Slave account.
Below the formula used to compute the slave order size:
The “Fixed Multiplier” 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.
If the minimum order size allowed by your broker for a specific symbol is bigger than the lot size computed, the Trade Copier copies the min trade size. In this particular case, the system always tries to copy the trade with the minimum allowed value.
