Quote from WyckoffTrader:
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?
Quote from Rehoboth:
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
