After installing software to the specified folder you can see "Files" folder there. This folder contains all Expert Adviser's files and dinamic libraries that you can install manually if you want. But I recommend to use "Software Installer" utility that you can call from the "Start" menu (it will make all the "dirty" job for you).
Anyway here it is the list of the files:
SignalProvider.ex4
Expert adviser that works with account to copy
SignalProvider.dll
Dinamic library needed for this expert
SignalProcessor.ex4
Expert adviser that works with your account
SignalProcessor.dll
Dinamic library needed for this expert
stdlib.ex4
Mql library required for these experts
Files location:
SignalProvider.ex4
<MT4 provider>\experts\
SignalProvider.dll
<MT4 provider>\experts\libraries\
stdlib.ex4
<MT4 provider>\experts\libraries\
SignalProcessor.ex4
<MT4 processor>\experts\
SignalProcessor.dll
<MT4 processor>\experts\libraries\
stdlib.ex4
<MT4 processor>\experts\libraries\
After copying files open Meta Trader 4 terminals and place SignalProvider expert to the terminal that works with account you want to copy, and place SignalProcessor expert to the terminal that works with your account.
Important! On each Meta Trader 4 terminal must be only one! expert adviser "Signal processor" or "Signal provider". Do not place these experts on every chart.
