Lesson 4: 16.4: Smart Order Routing Architecture & Exchange Fee Schedules
Examine multi-venue Smart Order Router (SOR) logic, maker-taker rebate schedules, inverted fee venues, and routing latency.
1. Smart Order Router (SOR) Architecture
Equity markets are highly fragmented across dozens of lit exchanges (NYSE, NASDAQ, Cboe, IEX). A Smart Order Router (SOR) scans real-time consolidated depth (NBBO) across all venues.
SOR algorithms dynamically split and route child orders to venues offering the best price, deepest liquidity, and lowest execution latency.
★ Fee Schedule Arbitrage: Exchanges operate Maker-Taker or Taker-Maker (inverted) fee models. Providing liquidity yields rebates (~$0.0020/share), whereas taking liquidity incurs fees.
2. Sweep and Router Latency
When sweeping liquidity across multiple venues simultaneously, SORs calculate optical travel times to ensure child orders arrive at different exchanges at the exact same microsecond, preventing HFT front-running.

Options are contracts cleared in the bid-ask auction market. Interact with the Order Book below to understand how buy offers (bids) and sell offers (asks) intersect, and inspect the structural breakdown between Call and Put contracts.

- Profit: Scales as stock surges
Right to Sell
- Outlook: Bearish (Goes down)
- Risk: Capped to premium paid
