When you set the Lot Ratio on the Follower’s trading account, this system will multiply the transaction lot which can be smaller or larger.

With Ratio, the size of the contract is not taken into account, so the formula is:

Follower Lot Size = Trader Lot SIze x Rasio

The value of this ratio can be a positive or negative value, the system will round up the lot size increase or decrease the lot size.

The thing to note is that the minimum order rules for each broker are different, in this case the system will automatically try to copy transactions with the minimum value allowed by the broker.
