Episode notes
Use Maker Quotes To Drive Price Discovery
- If you model a sport, actively post VIG-free or improved lines to drive price discovery and attract flow.
- Make one-sided quotes when you know the opposite side is wrong to influence the market without two-sided liquidity.
Point Models Break Across Many Markets
- Point-estimate models work for single outputs, but become fragmented when pricing multiple correlated markets.
- Sims naturally produce correlations and many validation touchpoints, reducing model fragility across derivatives.
Prefer Play-By-Play Sims For Coherent Pricing
- Use play-by-play simulations when you need coherent prices across many markets because sims produce correlated outputs by design.
- Prefer sims for league-wide pricing and derivative consistency despite higher engineering cost.
