connection between mt4 terminals

I want to see the spreads of 5 different brokers on a single Mt4 chart.
I mean on the first brokers EURUSD chart I want to see the other 4 brokers EURUSD spread.
I have searched named pipes but it  did not work despite of many tries.
Does anyone know another way to do that. Or you can share a named pipe code if you have a working one.

Thanks in advance.
