Not sure how the free trial works, I signed on a while ago and like everyone else gave my cc and figured they would charge like they said.
Anyways, I use the program and it's a good program.
I use Scottrade and they have their quote system too. I like Real Time. For me it's more customizable and has the L2 quotes. As for how well it works, it's been fine. I run both, Scottrade's program and Real Time.
Eventually, you will be able to trade through Real Time.
