Purpose
Make volatility-surface changes inspectable.
Derivasys is built and operated by Sean Gordon. Its reporting is designed to show what changed in the BTC options surface, how the measurements were produced, and which market stories may provide relevant context without presenting correlation as proven causation.
The site separates live product capabilities, educational material, engineering experience and evidence-backed research so readers can distinguish current observations from general explanation.
Coverage
Original data, recurring reports and technical depth.
Daily and weekly reports use stored Derivasys SVI surface snapshots. The wider publication covers implied volatility, smiles, skew, convexity, calibration, volatility models, market-data systems and production monitoring.
Browse BTC options market reports or read the surface methodology.
Accountability
Clear authorship, methods and contact routes.
Every recurring market report identifies its author, publication time, data window and commentary method. The editorial standards explain sourcing, automation, corrections and commercial disclosures.
Questions about coverage, ownership, commercial relationships or corrections can be sent to info@derivasys.com or through the contact page.
