Definition of the "Multiplier"

When using the “Multiplier (Notional)” or "Mutliplier (Lot)" methods, the system will multiply the master trade size by the defined value and place the corresponding order on the Slave account.

Using the "Mutliplier (Notional)" the contract size of master and slave symbols are considered and trade size will be adjusted accordingly. The multiplier will be applied to the notional amount of the master trade size. Here's how we compute it: Master lot size x Master contract size x Multiplier(Lot) / Slave contract size = Slave lot size

Using the "Mutliplier (Lot)", the contract size is not considered, so if it is different between master and slave symbols, the notional amount of the trade will not be the same. Here is how we compute it: Master lot size x Multiplier(Lot) = Slave lot size

Below the formula used to compute the slave order size:

fixed multiplier formula

The “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.
