flatted3rd, I just called Fidelity this noon. The trading expert told me that they will charge a $75 fee for even switching between different funds within Rydex family for short term trading.
I am using etrade. It does not charge any fee for switching funds in Rydex. But it does not have AM trading available. Is there any broker that does not charge a short term trading fee and also offer AM trading for Rydex?
