Have been devoted to this firm. Just do a search and you will find them. They have IB like commissions and blazing fast order execution capabilites. I trade on their Platinum software currently.
This was from a pop up ad on the link from the post above. Apparently you can watch them do live trades/executions as a live demonstration of their software programs. Looks pretty interesting think I will try it and see what is involved. http://www.pointdirex.com/live/en/ns/html/livedemo.htm
I've been with them for less than a week on the Direct Level one. This is an easy and cheap way to test them. Very intuitive & fast. Only gripe is that the charts are useless due to scale and the candle sticks frequently get corrupted. Being new I'd think improvements will be forthcoming. Phone service and email response has been nothing less than excellent, both in terms of response time and quality of help--hope that stays the same as they grow.
