Quote from optioncoach:
If you do enough volume they can give you $1.00 a contract on options. WIth their charting and option analyzer and other tools, as well as top notch customer service I do not mind paying the extra dimes. I also do futures and forex there as well so like IB I can do one stop shopping.
ToS still is behind on futures offering and does not offer options on futures so IB still beats them there. When they add options on futures at the end of this month as promised (I should say IF) it will certainly close that gap.
If you just want straight option trading and care not for some of the advanced tools or extras then you simply go with IB as they have more than enough to satisfy any option trader at a lower cost.
