The deeper pieces. Pricing models, vol surface calibration, hedging in thin markets, and the engineering decisions behind the systems that quote into East African capital markets every day.
Why the model has to know which thing is martingale, and what changes in the smile when you get it right. A working paper on the practical price differences when an options book is priced under the wrong measure.
Fitting a no-arbitrage volatility surface against sparse strikes, what works, what fails, and how the system handles missing observations under continuous online updates.
The slicing logic when the hedge instrument trades at a fraction of the options-leg notional. Basis risk between the hedge and the underlying, and the residual carry we accept by choice.
Reading of the NSE Clear IM methodology, how it affects sizing decisions on an OSF book, and what it implies for capital efficiency on the venue.
The pieces here are written at the quant-and-engineer level. Real model derivations. Real calibration code. Real architectural trade-offs. The infrastructure we run is the same infrastructure these pieces describe, so the technical content reflects what we actually do.
Specific over general. Reproducible over impressionistic. The work is the argument.
