few will tell you there rates. truth i it depends on how much vol you're doing and if you go to a big prop house like echo or assent or the 100's of broker delears popping up who have ties to a clearing house and software vendor.to broker dealers i've een have terrible service and crummy quote. with them doing 100k a day you can get .0025 plus or minus easy.with the assents and echo's you can get .003 to .0035.. personally i'd go with the more etablished prop house and pay a little more a the aggravation at the little broker dealers is terrible
