Reach for this when you're building or evaluating execution infrastructure that needs to satisfy best execution obligations under FINRA Rule 5310 or RIA fiduciary duty. It covers the mechanics of smart order routing across exchanges and dark pools, algorithm selection (VWAP, TWAP, implementation shortfall), and transaction cost analysis for both pre-trade estimation and post-trade measurement. The material goes deep on regulatory compliance mechanics like interpreting Rule 605/606 reports and running best execution committee reviews, plus market microstructure concepts like bid-ask spread decomposition and market impact. Also handles fixed income and ETF execution via RFQ protocols, which is less commonly documented elsewhere.
