Forex trading can be done with partnership also and it is good to combine the Signals and if you are having a same kind of trading personality then it would affect your Forex trading career in a good way because you might find it helpful to make the market as complex as it is
Trading in group is not always easy. There are so many important task and analysis to do for further actions. But for beginners i guess it can be done. Group trading is mostly convenient for expert traders.
Good luck.
