Actually, it's you who doesn't have a clue - http://www.federalreserve.gov/bankinforeg/reglisting.htm#T.
CashProfits, You need a margin account to sell spreads, period. Your b*tching about won't change anything, so get over it. Besides, it's not like you are required to use leverage when trading in a margin account! If you don't like Optionhouse go with another broker. Thinkorswim comes to mind, they don't have restrictions on the type of strategies customers can trade as long as you have...(you guessed it)...a margin account.
Now that's about as deep as your previous suggestion that the problem is due to trying to sell a call spread using options that are american style and that using euro style options is the answer. LOLOL. Go read what Reg T is about.
Hmmm... what was the name of the children's book where the tiger takes his own tail in his mouth and runs in circles around and around the tree? (scratching head)
Ok, I guess I meant what broker won't give me a hard time establishing a margin account? Is think or swim going to put me through a loop to establish margin? I'm not going to bother making accounts with 5 more brokers just to figure out who will cause an inconvenience and who will not. If people are perceiving my repeat post's as b*tching, sorry. It's because I have to keep repeating my post because people are responding with answers that show how little of my post they are actually reading. For those with good solid replies, thanks. I don't use those faces on posts so if you get emotional over internet postings, sorry about that.
i think i posted this earlier, but TOS [thinkorswim] will help you out. Easy to open an account, you don't have to fund with an insane amount and the customer support is great. you guys have it better in the US though, we don't have much choice, so this is gold.
