Need some help making decision: I am thinking about transferring my Roth IRA to MBTrader. When I look at their commission (Plan A "per-share") it looks that I ll be saving a lot. And when that happens I get very paranoid and start looking if I am missing any fine print. Here's my calculation: At present I have on avg around 4 order executions per week in that account. Avg size of each order is 100 shares. With Ameritrade I end up paying $44/week just in commissions. Same will cost me less than $5/week at MBTrader. Am I missing something? On MBTrader I ll have no monthly fees, $35/yr IRA fee. Dont want to go thru the hassle and know that grass is not green on the other side. I am also considering switching to iZone as an alternative, which may be less of a hassle to switch to but not the same savings. Can I switch without affecting my trading activity? (e.g. Having to hold on to losing stock because account s being switched) MBTrader guy said it could take 7 days for IRA transfer. Thanks for help !
