How to Prevent Signal Changing Lots

 
I subscribed to a Signal Provider, and the opened orders are on my MT4 which is the same as that of the Signal Provider but with the corresponding ratio.  But during the course of the trade, the Signal Provider doubled his equity, all of a sudden my opened orders lot sizes are all halved.   Is it part of the design of the Signal subscription program?  Is there anyway for me to maintain the orginal lot sizes?  As they are still waiting for their TPs and being cut half way means a loss to me.
