Writing on how markets actually work.
Long-form, figure-led, and free. The Foundations Series covers the mechanics every participant meets whether or not anyone explained them first; research notes follow as studies close.
Foundations Series
Interactive guides
Each guide is a self-contained interactive document with live calculators and generated figures. Nothing is gated and nothing asks for an email address.
Bid, Ask, Risk

Shorter writing
Notes appear here as they are written — on option mechanics, on how a session's structure is read, and on the studies that came back null.
Work in progress is not previewed, so there is nothing to list until there is.
Everything here is educational. No post on this site is investment advice or a recommendation, and no instrument, price or figure in the guides refers to anything real — the data is generated for illustration and labelled as such on each figure. Trading carries a real risk of loss. See the full disclaimer.
