Many do as Penson has a very low clearance rate. The one JBO I know best in VTraderPro and they clear ML and Goldman also. Why do you prefer Penson best?
Penson has the best locates, I can always find stuff there that I cant at Merril Pro and Goldman. But they have a funny way of doing margin at penson, so PM accounts get eaten up quick. If you know any other could you list or PM them. Thanks
I think they all are using tobacco's firm ...they are expensive though...couple pennies a share plus interest!
