Follow by Investment Ratio determines the number of lots to order based on the ratio of the follower's investment amount to the Master Trader's account balance.
For example, if you follow a master trader with $1000 in capital, and the master trader places an order for 1 lot, your follower will place an order for 0.1 lot. Note that orders for less than 0.01 lots will be ordered as 0.01 lots. Orders for 10 lots or more will not be copied.
