As a developer of image recognition algorithms, I, go_stock, am utilizing my knowledge and statistics in system trade rule development. I started interest in stock trading by writing my own program in Ruby to develop rules and begin operation. In the first few months, I achieved nearly 10% monthly returns, but gradually things started to go poorly, leading to continued losses. When I began to feel the limits of my own program, I learned about Izanami and purchased it immediately. I am deeply grateful for its overwhelming development efficiency and ease of fund management! The guiding principle for rule creation is that it should be easy to continue even as a side job. After all, I can’t monitor prices during the day. And my goal is to travel to all the World Heritage sites around the world with passive income earned from trading, savoring local cuisine and drinks. If possible, in business class ^^; And from 2020, I started FX system development with MT4 as well!! I’m once again hooked on indicator development.

Series
An app that scores all TSE Prime stocks on a 100-point scale.
First, development guidelines. And I will post weekly analyses every week. This is the logic for selecting long- and short-term stock picks that I actually manage. Each week's analysis will start with market analysis and then introduce the selected individual stocks. For the time being, it will be公開 for free. It is time-consuming, so it may become paid content. Please refer to the article for details.
