I'm originally a Florida resident I toke mid office job with an investment bank in PA 2 years ago and I'm am relocating back to Florida in June. and I will be trading with a prop firm, there are some good options out there now in S. Fla. here's a few:
Trillium Trading
Echo
Bright
Assent (several offices)
Broad Street Trading
First New York Securities **(Maybe the best on the street right now)
Pro Trade Securities
...I'm personally leaning towards going with Pro Trade or Broad Street
