What firm is best(Leverage, commissions and platform) for a pairs trader who trades between 3 and 5 Million shares per month? Any advice would be appreciated.
For pairs you need overnight leverage and they are def the most lenient. As long as you have some discipline they will give you a long leash. I traded there for about a year. Solid firm, no worries about your money.
Assent is another good firm, but your money is tied up for a year. No opinion on Hold.
Hold Brothers and Assent give the best rates (sub $2/1000 for 2+ mil/month). Dunno much about Bright, but I had heard that they are not competitive on rates. I think Assent and Bright give better leverage than Hold (20-1 overnight vs 6-1 overnight, intraday is even).
