Its a suffix the broker uses, that makes copying difficults for potential subscribers using other brokers.

 

Broker's use a variety of naming patterns: EURUSD, EURUSDc, EURUSDct, EURUSDecn, EURUSDi, EURUSDm, EURUSDpro, EURUSDt, "EUR.USD", "EUR/USD", "EURUSD!", "EURUSD#", "EURUSD.", "EURUSD..", "EURUSD.c", "EURUSD.cfx", "EURUSD.G", "EURUSD.SBe", "EURUSD.stp", "EURUSD+", "EURUSD-5", "EURUSD-sb", etc.

I'd guess: Contract For Difference eXchange.
