Going through it right now ...... With Tradier, you need to have at level 5 or 6, you need to have 25 k or more, and you need to have a margin account in order to trade straddles and strangles ... Oh and don't try to ACH the money to them as they will not accept more than 10k in ACH... it has to be wired into your account.
Unfortunately they do not tell you all of that up front they bring you along one bit at a a time... (if you are using a SO Deal, you would think they might let you know all of this)
