IMO, the Firstrade Roth or regular IRA is not suitable with SteadyVol considering the following information:
STEADY OPTIONS
ITM debit and credit spreads on front and back month VIX futures hedged by a ratio of long calls
FIRSTRADE GENERAL
Which option trading/investing strategies do you provide?
Currently we support writing Covered Calls (including Roll Forward), writing Cash-Secured Equity Puts, purchasing Calls & Puts; as well as Spreads & Straddles, Butterfly & Condor (including Iron Condors); and writing Uncovered Puts.
Please note that at this time we do not support Calendar & Diagonal Spreads on Index Options.
FIRSTRADE IRA
What types of investments are eligible for my IRA account?
You can invest in stocks, bonds, mutual funds, CDs, and options (write Covered calls, write Cash-Secured Equity Puts and purchase Calls & Puts only) just like a regular cash account.
However, the use of margin is not allowed for IRA accounts.
