What is the rate schedule one can expect these days for in-office trader, who doesn't do much volume but can regularly earn low/mid-5 figures monthly? I've averaged less than 2mm shares for a while now, but lately gotten into a groove and with some new strats and added size I'm expecting my volume to increase shortly. How much leverage is profitability if at all in negotiations, given my low volume? As it stands now, I know my rates are on the high end, but now I need to map out a fair deal for upwards of 5mm shares/month. Right now it's cheaper for me to trade through interactive brokers with their all-in rate, and I can easily funnel more volume through them as an alternative since I don't scalp much, but that's a bit apples to oranges.
