I'm launching a small hedge fund and shopping around for a good executing firm. We are currently executing our derivatives with Refoc (PMB). We have an allocation in our portfolio to active trading on OTC's. What is the consensus on Interactive Brok.? How does it compare with other firms as far as execution is concern. Are 0.05 cents inclusive of pass through fees. Have they disable their direct ECN. How is there best ecn routing. Execution time? Customer Service? What's all this with the PRIMex controversey. any help would be great.
