If you're using a Standard account, it says in black and white per the characteristics of that account type that 1 pip (not 0.1 pips; each unit in the fifth decimal place per say EURUSD is equivalent to 0.1 of a pip) is added to the spread, in lieu of commission.
What is the problem exactly?
If you want naked spreads get an ECN account instead; you'll pay commissions but your spreads won't be incremented by 1 pip.
The bottom line is that ICM has to get some kind of compensation from executing and routing your transactions as your broker, whether it be in the form of commissions, or spread.
