Comission cost calculation in a strategy?

[NinjaTrader_ChristopherJ]

Are you referring to changing the account used within your strategy from Sim101 to another account? If so this will require a Live NinjaTrader license key and will be changed within your Strategy window as referenced in my attached screen shot.

Ok, thanks then this is the expected behaviour allways use the simulator to set the comission unless using the live license key.
