About the author and how we write
I. D. Galtsov — Author of the Extremum course, reference and glossary, and developer of the app.
What has been built
A 119-lesson course with exercises on real charts, a 96-article reference, a 221-term glossary, answers to beginner questions — in five languages: English, Russian, Kazakh, Ukrainian and Uzbek.
How the materials work
The correct answer to every exercise is calculated in advance from historical data and stored in a database. The AI mentor never decides correctness itself — it only explains the known answer, which rules out model errors where money is involved.
One set of markup rules
All materials use one terminology: BOS is a break of structure with the trend, CHoCH is the first break against it. Zone boundaries use the full candle range, a break counts only on a close beyond the level, and the entry zone is the 0.25–0.75 band of the quartile grid.
What you will not find here
No trading signals, no "buy" or "sell" recommendations and no promises of income. No real money inside the app — only learning and a virtual account. Every page states that trading carries a risk of loss.
