What broker do you guys use for Options Trading? Many ppl seems to be using ThinkOrSwim, what about others like IB or Saxo etc? Which one offers lower or better commission rates?

If you are going in alone without a community discount comm structure, use IB. But you will need to eat the data feed fees unless your trading volume is sufficient to offset the fees.

I'm using TD with a community discount rate that is very comparable with IB
