The Subscription Strategy decides the final copied lots of your position, and whether the position from the provider can be copied or not.

Mode:

Autoscale: It allows a follower to copy a provider based on the funds ratio between them. The trading volume can be calculated based on the funds ratio and control the risk.   

Multiply: It allows a follower to directly copy a provider based on the Volume Multiplier amount. The follower will copy the trading lots which will be multiplied by the amount that is set up.

Fixed: It allows a follower to directly copy a provider based on the Copies' Volumes. No matter the lots of the provider's positions, the follower will directly open the lots that are set up under this mode.
