I will show you how to utilize economic indicators, news analysis results, and technical indicators to build a business.

Once you complete this course, your system will be built, and you will be able to operate it yourself.

Here is what you will learn.

Stock Theory

Don't worry if you're new to stock investing! We will explain the basic concepts and terminology of stocks one by one, and you will learn practical investment strategies based on the top 25 Nasdaq stocks. We cover stock theory in a way that even beginners can easily understand.

Data Collection

Learn how to collect real-time stock data using Fred, Yahoo Finance, and Alpha Vantage APIs. You will learn the data preparation process for news sentiment analysis and technical indicator calculations, while storing the data cleanly in PostgreSQL.

AI Prediction Model

Design a model that predicts stock price rise probability and accuracy using AI. Select purchase targets based on Rise Probability and Accuracy, and create a system with even stronger predictive power by combining news sentiment analysis with technical indicators (RSI, MACD, etc.).

AI Code Generation

Using AI and "Vibe Coding," we will write the code for an automated stock trading system without writing a single line of code yourself. You will learn how to automate buy/sell orders by integrating the Korea Investment & Securities API and develop efficient code for real-time data processing. With the complete source code provided, there is no need to waste time taking notes or manually typing along with the lecture.

📢 Frequently Asked Questions (FAQ)

We have collected the most frequently asked questions before taking the course. Check your questions quickly!

If you have any questions that are not covered here, please feel free to leave them on the Q&A board at any time.

We will provide a kind and detailed answer as soon as we check it!

[Target Audience and Prior Knowledge]

Q. I don't know much about Python or computers; is it okay for me to take this course?

A. Yes, it is possible. We provide a detailed guide starting from the initial environment setup, and since we use the 'Vibe Coding' method—where you implement desired functions through verbal instructions—you will be fully capable of creating your own system if you follow along step-by-step.

Q. Can a beginner developer (e.g., 1st year) follow along?

A. Yes. This course is designed around the core processes of economic indicator collection, machine learning prediction, technical analysis, and news sentiment analysis. Even if you have little development experience, you can build practical skills by experiencing the entire process of system construction firsthand.

Q. Can I use a MacBook?

A. Yes, that is not a problem. All library installations and structural organization used in the lecture are applied regardless of the OS platform, so you can follow along with the practice in a MacBook environment in the same way.

[Course Composition and Recommended Path]

Q. Do I have to take the previous lectures?

A. It is not a mandatory requirement. This course is designed as a practical, condensed version, so you can proceed directly with the practice using the core AI model code from the previous course (Secrets of Algorithm Trading: How AI Predicts Stock Prices). However, if you wish to deeply understand the internal logic of the model, we recommend supplementing your learning with the previous course as needed.

Q. What is the difference between the Basic (Introductory) and Completion versions?

A. While the 'Basic Edition' focuses on building a fundamental framework using Python and FastAPI, the 'Complete Edition' provides advanced practical source code for a fully automated trading system by combining deep learning and LLM (Claude) to include features such as bear market protection, self-error recovery, and real-time alerts.

Q. There are several auto-trading courses; which one should I take?

A. We have organized three lectures into one connected roadmap so that you can systematically learn market analysis and automated trading with as little trial and error as possible until you build your own automated trading system. Please refer to the guide table below and select the stage that fits your current capabilities and goals. (If you are viewing on mobile, you can see it clearly by zooming in with your fingers.)

Cheat Key Man's Automated Trading Course Roadmap Comparison Chart

[Practical Automated Trading and Technical Support]

Q. Can I trade other stocks besides the top Nasdaq stocks?

A. Yes, it is possible. Since the Korea Investment & Securities API supports the entire US market, once you have mastered the course content, you can freely change and expand your operations to any stock code or exchange (NYSE, AMEX, etc.) you desire.

Q. Why use Cursor IDE instead of VS Code?

A. It is because of productivity and efficiency. Cursor possesses all the advantages of VS Code while being optimized for AI code suggestions, making it the most suitable environment for performing 'Vibe Coding.'

Q. Do I have to use TradingView?

A. No, it is not used. This course focuses on 'automation,' where the system analyzes data and executes trades automatically. It is designed to manage trading status through your account without the need for a separate chart UI.

Q. Are returns or win rates guaranteed?

A. This course is not an investment lecture that guarantees profits, but a technical lecture on designing and implementing your own automated trading system. Although actual test results showed good accuracy, it is necessary to understand that risks exist depending on market conditions and to personally research investment strategies.

Current Status and Lecture Goals

Currently, as a large corporation IT developer, I am achieving results in various fields such as service development, performance improvement, blockchain, AI, cloud, infrastructure, and information security. At the same time, I am continuing to take on new challenges by combining practical work with business through a platform that I personally plan and operate.

I believe the essence of IT lies in practical application.
Through this lecture, I want to convey the following to you:

  • How to effectively apply technology to real-world projects

  • How to solve practical problems in the field

  • Practical know-how that allows even non-majors to create their own businesses or portfolios.

IT Cheat Key Lecture: Learning Only the Essentials

My lectures do not simply convey theory. I will help you learn only the essential core without wasting time, incorporating practical experience and sincerity.

IT is vast and has a wide scope of study, but you don't need to know everything.
If you learn exactly what you need and master how to use it effectively, anyone can utilize IT like an expert.

I will become your IT Cheat Key so that we can find new paths, continue successful challenges, and create moments together where technology becomes a powerful tool that changes lives.
Thank you! 🎯
