Accessing Commissions

Hello,

Does anybody know how to access the commission of a market without having to execute an order in the same way one can access the swap?

There are simple commands for acquiring the swaps:

double SwapLong = MarketInfo(Symbol(),MODE_SWAPLONG); 

double SwapShort = MarketInfo(Symbol(),MODE_SWAPSHORT);

However, the only command I can see available for acquiring the commission is to open an order, select it, and then use the command:

double Commission = OrderCommission();

There must be a better way to do this, without having to open an order?

Thanks.
