This is already done. There is an per-order fee and a per-trade fee. All your proposal would do is shift the balance slightly between these fees.

- throwaway283719 12y agoWhat markets is this done on? On most markets that I'm aware of, there is a fee for passive trades and a fee for aggressive trades. Sometimes the fee for a passive trade is negative (a rebate) which encourages liquidity provision, but I don't know of any market that actually charges per order, and then rebates that proportionally to the liquidity providers. One proviso is that I've never worked on US equity markets, so if this rule is in place there then I wouldn't know about it.
- yummyfajitas 12y agoIn US markets there is a (very small) per-order fee. There are also rolling windows and disconnections for people who go crazy with quote spam or have low fill rates.
