    Introduction to financial engineering

    The course has begunin the previous version of the Hexlet project, but in this author Dmitry Nesteruk decided to rework the course and start it again. The purpose of the course is to give students the skills to comfortably understand and participate in international financial markets. The course provides the basic knowledge required to understand the structure of markets and instruments traded on them, questions of pricing, as well as technical aspects of trade.

    At the moment, about five hundred students have enrolled in the course.

    - First lecture (Instruments and Markets. Introductory lecture on financial markets and instruments that are traded on them)
    - Second lecture (Derivatives. We talk about options, draw option payment charts. Finally, connect via Plaza II / C-Gate, look at interaction with the exchange, we write the structure of the "glass")
    - Third lecture (Binomial Model. We discuss a binomial model for calculating the value of an option, build glasses on FORTS)

    Lectures are published once every few weeks.
