I just got done with my accounting. In 2010 I paid almost $50,000 in commissions to IB trading oil futures. Any one has any suggestions how i can reduce my cost of commissions? I do like the TWS, the way I am able to easily create and modify orders right on one line. Is there another broker out there that has lower commissions but uses a trading platform similar to TWS. I do not use and do not like the level II quote window. Thanks for ideas.
