The past month I have been talking with many firms. I am interested on the general concensus on the fees that need to be paid along with commission for trading that relate to trading. I will start with some that I know. ECN Fees/Rebates : Pretty self-explanatory. SEC Salex tax: Currently $39.00 Per 1 Million sold (?) NASD Transaction fee: how much is it? Is it only for NASDAQ or for all exchanges such as NYSE and LISTED ACT Fee: I understand these are reporting fees. What are they? Exchange fees: Does someone have like a table or something of those fees? And not the ones that brokerages charge, but the official fees? Data feed fee: Do you guys pay it? How much? any concensus here? Any other trading related fees (i don';t mean like a Desk fee or Software fee) Am I correct with the above?
