Recommended for these people

I want to easily develop anything using AI.

I will show you everything from design to implementation and operation, demonstrating without filter how to build across the entire IT spectrum using AI.

I want to understand and build AI prediction models.

We will show you how to utilize actual raw data.

I will show you how to derive insights based on the collected data.

I want to create a business by applying IT to economics and stocks.

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 process of storing data cleanly in PostgreSQL and preparing data for news sentiment analysis and technical indicator calculations.

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

We will create a stock automated trading system using AI through "Vibe Coding," 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 how to write efficient code for real-time data processing. Since the complete source code is provided, there is no need to waste time taking notes or manually typing along with the lecture.

📢 Frequently Asked Questions (FAQ)

We have gathered 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!

[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 detailed guidance 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 building 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's no problem. Since the installation of all libraries and the structural organization used in the lecture apply regardless of the OS platform, you can follow along with the practice in a MacBook environment in the same way.

[Course Curriculum 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 defense, 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 better by zooming in with your fingers.)

CheatKeyMan's Automated Trading Lecture Roadmap Comparison Table

[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, and 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 developer at a major IT corporation, 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 experience with business through a platform I personally planned and operate.

I believe the essence of IT lies in practical application.
Through my lectures, 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.

  • Ways to approach and enjoy IT easily

 

An IT Cheat Key Lecture to Learn Only the Essentials

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

IT is vast and the scope of study is wide, 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! 🎯
