Normally you can't sell options if you don't use a margin account. But is it possible to sell a covered call? since there is no margin in it when the stocks sit right there.
I don't know. It should be. It is possible in etrade and was in Schwab and brownco. Call them and ask them.
Just half a decade off. But, I don't think exist anymore. Was nice being grandfathered for that flat $5. However, commissions have dropped since then. I think some optionshouse guys got $2.95, grandfathered like BrownCo. No direct connects to APEX though. Just webtrading.
By definition, a covered call means you already own the stocks so all brokerage account should allow whey you apply. If you try to sell naked, most cash account I know won't allow.
