Routing fees, do-not-ship flags, and maker-taker limit orders

A limit sent to one exchange can be shipped to a better-priced venue, held with a do-not-ship flag, or executed as an immediate take. Each path carries a different implementation cost.

  • When a limit is sent to one exchange at a price inferior to the national best bid and offer on another market center, national-market-system rules can require that venue to route the order onward, and that shipping often carries a per-share routing fee of about three-tenths of a penny.
  • A do-not-ship designation can block that extra outbound routing, but it also forgoes automatic access to a better displayed away price.
  • Providing liquidity with a resting limit typically earns a rebate, while taking liquidity typically incurs a take fee, with a common maker-taker rule of thumb around the period near $0.002 to provide and $0.003 to take.
  • Flash orders and subpennying can leave a displayed limit unfilled while trades occur a fraction of a cent ahead of it, which weakens the incentive to post and leave resting limits.

An editorial reading of the charges

Editorial: treat routing, shipping, and maker-taker charges as order-design choices rather than invoice noise. A resting limit, a do-not-ship flag, and an immediate take each buy a different fill path and a different implementation cost.

Outbound shipping and the routing fee

When a limit order is sent to one exchange at a price inferior to the national best bid and offer on another market center, national-market-system rules can require that exchange to route the order to the better-priced venue.

That outbound shipping or rerouting often carries a per-share routing fee of about three-tenths of a penny, which compounds across active order flow.

The do-not-ship choice

A do-not-ship designation can block that extra outbound routing, but it also forgoes automatic access to a better displayed away price.

Shipping is economically justified only when the price improvement is a full penny relative to a much smaller routing charge.

Maker-taker fees on provide and take

Resting a limit that is later executed is providing liquidity and typically earns a liquidity rebate. Immediately hitting a bid or lifting an offer is taking liquidity and typically incurs a take fee.

A common maker-taker rule of thumb around the period paid about $0.002 per share for providing liquidity and charged about $0.003 for taking it.

Flash orders and subpennying

Flash orders give a brief, non-displayed look at an incoming order before it is routed or posted. Subpennying can print or display a fraction of a cent ahead of a resting limit. Either can leave that displayed limit unfilled while trades occur a fraction of a cent ahead of it, weakening the incentive to post and leave resting limits.

Arguments that flash mechanisms save money by avoiding venues with taker fees omit the market-quality costs of less transparent, less competitive quoting.
