Can anyone suggest the best way to convert my traditional IRA (held at IB) to a Roth ira (I already have a Roth IRA held at IB I'd like to merge the rollover into). I know IB won't do it although I keep hoping they'll support this. I'm assuming I need to do an ACAT to another broker such as Scottrade, Etrade, etc which will handle it, then do another ACAT back. IB why oh why won't you support this? 2010 is a big year for this since you can defer paying taxes until 2011 and 2012 (although tax rates will likely go up).
