This section of our book is very specific. If you are familiar with programming and have a penchant for it, then you will like the section. If you are not familiar with programming, but you think that you really need it, we will try to literally chew everything so that the general principles are clear. It should be understood that programming is primarily reading volumes of documentation on the programming language and studying examples, and practice is also inevitably needed. In general, it takes years of training, perseverance. On Youtube you can find a lot of contributing materials on this topic. In my opinion, the main thing here is to remember that you are doing this to earn money, and not to create masterpieces of programming ideas. Often, an algotrader cares only about the constant improvement of the algorithm, and he no longer sees the essence of why he does not earn.
