When using the “Auto Risk” method, the system will keep the same ratio of the trade size versus the account size between the Master and the Slave accounts.
Below the formula used to compute the slave order size:
The “Account Size” can be defined using the equity, the balance or the free margin of both Slave and Master accounts.
The “Auto Risk” 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.
