If IB makes you nervous, there are many alternatives to choose. Most of us here like them because of ALL the products that we can trade thru one broker and let the little problems that arise from time to time not cloudgood luck the big picture. No broker is perfect, so if that is what you seek, it is a Quixotic endeavor.
That being said, it appears you want to trade equities and not futures or forex, so look into Lightspeed, Genesis, or maybe MB Trading. Both Lightspeed and Genesis have retail account divisions, but both these platforms are used by various prop shops throughout the country so you can be assured that the platforms are good for daytrading equities. Can't speak for MB Trading, but there are some people here who are content with them.
