Miles! Thank you for your thoughtful and detailed course review. Since you said it is worth reviewing, I think I should work harder to make a good course. Although my quant course is a course that pursues practical applications, if I were to seriously engage in practical investment, the code and logic would become more complex and sophisticated. However, this would make the students feel that the code is more difficult, so although it is intended for practical use, the code has been simplified a bit while considering the difficulty. So, what I recommend is that you implement Miles' own algorithm when reviewing. And I think that implementing your own algorithm like this will be a good portfolio when preparing for employment. Also, since the Interactive Brokers API, which will be covered in the second and third lectures, will use a virtual Paper Account, even if Miles' own algorithm incurs a loss, you can immediately readjust the virtual account amount of the Paper Account, so you can practice various algorithms. Thank you again for your review, and please let me know if there is anything else I can help with (e.g. reviewing your own algorithm portfolio, but there may be a fee for the algorithm review) and I will do my best to help. Thank you, Daniel Dream
