You can't aggregate the clearing fee away. It's applied to every trade. And clearing fees are small compared to exchange fees anyway. There are some fixed fees

You can't aggregate the clearing fee away. It's applied to every trade. And clearing fees are small compared to exchange fees anyway. There are some fixed fees to be designated as a market maker on some exchanges. Others just charge based on a free-for-all maker/taker model. Another "fee" that market makers incur that retail customer don't is direct market data, which is painfully expensive. But that's fixed, not a function of trades.
