IB charge for overnight futures

I have noticed that IB charges for future position held overnight, Does anyone know if other brokers charge for this, if so what is the reason

 

R.J.O' Brien/ Tradestation charges .10/Contract, for overnight positions. This is really putting a damper on my budget for Russian hookers.

 

IB only charges the carrying fee if you are unbundled, right?

 

You are correct. No charge if paying bundled commission rate.

 

thanks for the info. Now that makes it even harder to calculate
