Finance Track Reorder — Design

Date: 2026-04-19

Problem

The finance-main-path track (19 notes) has ordering issues:

  • Volatility (derivatives) wedged between microstructure notes
  • DeFi block (9 notes) makes the track too long and mixes TradFi/DeFi
  • IPO and trading-venues tacked on at the end with duplicate step numbers
  • Black-Scholes missing despite being referenced by Greeks and DeFi notes
  • Greeks placed before Black-Scholes (Greeks are B-S partial derivatives)
  • Glosten-Milgrom uses “martingale” without definition

Solution

Split into two tracks. Reorder the main path.

Additional fixes

  • Create black-scholes stub (step 10)
  • Add inline martingale definition in glosten-milgrom-model
  • Add concrete numerical example for margin math in settlement-and-clearing
