I've been offered to trade for a very reputable prop firm so that is not a concern. My contribution is $10k with 100% payout and standard fees. I need to take the Series 7 exam. I've just been told that to get started I need to send them $900 for processing my paperwork (the fee schedule will be in this paperwork). This $900 fee includes fees for "exchange, exam, and processing". Can someone tell me if this is normal or not?
