I was trading Profunds with Schwab back in late 2003/early 2004 when I first started trading off models. After getting whacked with their commissions a few times I moved directly to Profunds. Since my account was decently into 6 figures, I got lots of calls asking me why I'm moving. I told them that they cannot hold Profunds and Rydex trading to the same commission structure as "normal" mutual funds as they are set up for daily trading.
