The top volume players pay less than the publicised membership exchange fees on some exchanges. I dont know about eurex. In some instances on challenger exchanges they are paid to trade.
That's what I think as well... I'm pretty sure fees were lower than that when I traded on Eurex. Although I traded more in options...
But with exchange fees being the biggest part.. you wouldn't be way of the 20 cents.
If I remember correctly our fees on options were about 10-14 cents per contract... and when an active MM it was about 5 cents since you would get a massive Eurex rebate.
