If you do enough volume anything is negotiable. I have been able to get a reduced rate due to monthyl volume. But if you do 10 contracts a month I do not think you will get much of a break. as for what kind of volume woudl lead to a break in commissions, it all depends on ToS so just ask them but only do so if you are really trading more than 1 contract lots 4 or 5 times a week.
I'm doing 20-30 contracts per day minimum there was few days when it reached over 100 today already 52
i mean are TOS the best broker out there or what .i just got 2.50 per side .from 3.50 originally i was paying.i know its still higher then at some places but u know what that works for me perfectly .
