I know this thread is a bit old, but I'm having the same issue. I just setup my IB Roth IRA Margin account and my permissions are enabled for "Complex or Leveraged Exchange Traded Products" but VIXY, which is a leveraged & inverse ETF is not available for trading? There may be others but this is the one I noticed so far because I love to trade this. There's many leveraged & inverse ETFs that ARE available for trading but not this one? I'm able to trade VIXY in my Vanguard Roth but not in my Roth IRA with IB? Why? I tried rebooting TWS- no joy. Maybe there's something more I need to set in my permissions? Thanks.
