Completion of the Pillow Investment Method: AI Stock Fully Automated Trading for Exciting Mornings - Claude Vibe Coding

"Why does my automated trading collapse in a bear market?" I have also deeply pondered this same question. Most automated trading logics on the market seem to generate profits during a bull market, but they lose their ability to respond the moment the market sentiment changes. To solve this problem, I have combined the know-how I researched myself over the past two years with the latest AI technology. In this course, you will learn how to directly design a 'Transformer-based deep learning model' that simultaneously reads macroeconomic trends and individual stock flows, and how to automatically train and deploy it in a free GPU environment. In particular, we will introduce sophisticated data normalization techniques at the hedge fund level to build an 'Intelligent Comprehensive Scoring System' that goes beyond simple indicators to incorporate news sentiment. To this, we add an 'AI Safety Gate' that implants the insight of a trader with 20 years of experience on Wall Street, adding a final layer of confidence from a human trader's perspective right before a purchase. Beyond simple buying and selling functions, you will directly implement the entire process of an institutional-grade algorithmic system by adding dynamic take-profit and stop-loss logic, eight self-recovery mechanisms, and real-time Slack reports.

🔥 Update (2026.06.28): Now 365 X 24 Auto-Trading even with your PC off 🔥


24/7 uninterrupted operation without a PC (AWS Cloud Deployment)

By uploading the automated trading system to an AWS server, it operates 24/7 without interruption even when your PC is turned off. Even if the server unexpectedly shuts down or reboots, the program will automatically restart. The entire process—from server creation and environment setup to persistent execution settings and deployment—is covered in the video.

Automatic detection of stocks with imminent earnings releases and AI buy decision-making (Earnings calendar integration)

Just before purchasing, the stock's next earnings release date and expected EPS are sent to the AI (Claude). The AI directly checks stocks with upcoming earnings announcements and makes the decision to buy.

Implementation of Enterprise-Level Practical Security (Security Hardening)

RLS has been enabled for all tables in the Supabase database, and server-only keys have been separated. With server firewall settings and environment variable file permission locks, we have achieved enterprise-level operational security.

Relaxed buying criteria to include bullish stocks (Logic improvement)

Fixed the weekend time determination error and relaxed the RSI buy criteria from 65 to 85 to include strong stocks in the buy candidates.

Your automated trading runs 24/7 on an AWS cloud server without the need to keep your PC on.
Even if the server stops, it will automatically restart.

🤝 Close personal care directly from the instructor "until it's resolved"

"We take full responsibility and provide support until your system is up and running."

  • Detailed answers provided directly by the instructor as quickly as possible (within 24 business hours) when you ask a question

  • Detailed guide and close support for troubleshooting


🚨Even if you are new to coding or a beginner in stocks, you can complete a professional-level system through the provided full source code and step-by-step guide.

💲Cloud API around 3,000 KRW/month, etc. $5/month when using AWS server

"Are you repeatedly making regrettable trades because you are swayed by emotions whenever the market fluctuates?" In the midst of rapid trend changes, an individual's emotional judgment can become a cause for increased risk. If you have felt that you need objective risk management based on data and a systemic response infrastructure, this lecture will be the turning point for completing a stable automated stock trading system.

This course is a process of building a '100% fully automated trading system' exclusively for you, something that commercial stock apps never provide. Anyone can make money in a bull market, but true skill is revealed in a bear market.

Based on the know-how of designing large-scale financial systems, I have completed a robust system that recovers itself from unexpected errors and runs 24/7 without stopping. Furthermore, I have built a 'multi-layered defense logic' that filters and verifies stocks through multiple stages to safely protect my account from market risks such as sudden crashes and volatility.

It is not a simple conditional search formula. You will directly implement everything from the 'Transformer-based deep learning model' that reads macroeconomic and individual stock trends, to a data pipeline that analyzes news sentiment, and an 'AI Safety Gate' embedded with the insights of a trader with 20 years of experience on Wall Street.

Now, even if you don't know how to code, you can own professional-level algorithms through Vibe Coding and our step-by-step guide.

Even while you sleep, the system monitors the market every minute and executes dynamic take-profit and stop-loss orders. When you wake up in the morning, instead of the fear of a market crash overnight, a friendly profit report from your AI assistant via Slack will get you excited.

Not just a simple tool, but a true 'Pillow Investment Method' that will protect and grow your account. Start right now!

"Now

Instead of the fear of a falling market overnight,

Today, my automated trading Agent

wondering how much profit it has brought again

Every morning before the alarm goes off,

You will wake up with a heart full of excitement."

Fully automated trading that implants the institutional-grade quant strategies of a large-scale securities system developer and the cool-headed judgment of AI


Of this lecture's algorithm

This is the actual return on investment.


I didn't do anything.

These are the results of the AI system making its own decisions and executing trades.

  • Investment Amount: 10,000,000 KRW

  • Period: May 6, 2026 – May 27, 2026 (21 days)

* Captured immediately after waking up at 5:50 AM on May 27, 2026


* These results are actual records operated in my Korea Investment & Securities real account.


🚨 March 2026, Global Stock Market Crash

In March 2026, when everyone was recording losses

  • Market Situation: Global stock markets crash indiscriminately due to the aftermath of the U.S.-Iran war and the oil shock (green box in the chart above)

  • The reality for average investors: Mental breakdown leading to panic selling and leaving losses unmanaged and helpless


🛡️During the same period, the defensive power of the 'Pillow Investment Method: Complete Edition'

During the same period, successfully defended a +1.48% return

  • Actual Results: Even while the market was plummeting, the logic worked to achieve a +1.48% profit defense!

  • The secret to success: It's not just a simple hunch. Transformer-based deep learning and risk management algorithms detected downward signals in real-time to protect assets.




"We designed risk defense as the top priority even amidst market volatility."

This is the difference that only 'institutional-grade quant strategy AI' can provide, rather than a simple rule-based bot.


🛑 Have you ever felt this kind of 'frustration' after taking other automated trading courses?

There are 3 real reasons why many people try automated trading but eventually give up.


1. "They said it was automated, but it requires too much manual work"

  • Do you have to manually collect data every morning and enter various commands by hand? That isn't automated trading; it's just a 'manual assistance tool.'

2. "A system without exception handling is unstable to run at all times"

  • If the program stops due to an unexpected error or hits API limits while you are at your main job, real-time response is impossible. A system without a self-healing mechanism can hardly be considered true automation.

3. "One-dimensional strategies focused primarily on bull markets are vulnerable to market changes."

  • Simple technical indicator breakouts or fixed conditional search formulas find it difficult to respond flexibly when market trends change. Only when dynamic risk management and defensive filters are combined does it become a sustainable trading engine.


💡 The Final Edition of the Pillow Investment Method is the 'final destination' for individual automated trading.

We provide a complete automated trading system created by an expert who led the system design and development at a major securities firm.


1. True 100% automation where you "don't even have to lift a finger"

  • Integrated from data collection and analysis to buying and selling:

    • With built-in FRED macro indicators, news sentiment analysis, technical indicator analysis, machine learning Transformer model training, and a real-time price pipeline, no manual intervention is required at all.

  • Real-time reporting by Slack assistant:

    • The AI compiles the logical reasoning behind "why it purchased this stock" and reports it via Slack.


2. "Staying operational is the real skill" Professional-grade self-healing logic

  • Self-healing mechanism:

    • The system automatically retries and recovers on its own even in the face of unexpected issues such as network errors or API limits. Designed with operational stability as the top priority, it ensures you never miss your precious trading opportunities.


 3. A Multi-Layered Defense System that "Protects Profits Even in a Bear Market"

  • Machine Learning Transformer + Technical Indicator Scoring Model + Claude 4.7 AI Gate:


    • 37 types of macroeconomic indicators are used to read market trends, and deep learning predicts stock prices.

    • 7 core technical indicators are converted into a comprehensive score to select the most promising stocks.

    • An AI with the perspective of a veteran trader with 20 years of experience makes the final decision on whether to buy.

🧭 Overall System Architecture


💎 Differentiation points of this lecture


🧠 AI review of purchase selection targets:

Bots that buy simply when indicators align are dangerous. We will build a multi-layered defense system where an AI agent performs a final review of market conditions immediately before purchasing.


🛡️ Automated trading pipeline combined with risk safety mechanisms:

The entire process—buying based on data predictions and AI reviews, and selling based on four situational rationales—is protected by a robust risk-shielding system.

💵 Intelligent operation achieving ultimate cost-effectiveness


💰 Overwhelmingly cost-effective operation:

  • Operates 24 hours a day at a reasonable cost of approximately 3,000 KRW/month (Claude API) and $5/month (AWS Cloud Lightsail) (excluding electricity/internet costs, etc.)

🤖 100% Automated Operation:

  • Automatically trade and manage without repetitive commands

📢 Operation Report Notification: 

  • “What was bought/sold today and the reasoning behind it” is reported as a summary via Slack (enhancing operational visibility)


STEP 01. [Analysis]

Market Scanning& ML Stock Price Prediction & AI Final Approval

"An investment strategy that increases probability by predicting based on real data and verifying with AI"

  • Integrated Data Scanning: Reads the market context by combining FRED macro indicators, real-time quotes, and news sentiment into one.

  • ML Transformer Prediction: Deep learning models analyze vast amounts of time-series data to precisely extract stocks with the highest probability of rising.

  • AI Final Gate: Logically reviews target stocks for purchase and grants final buy approval.

STEP 02. [Execution]

Sophisticated entry based on institutional-grade quant strategies

"Removing emotion to capture the optimal buying point."


  • Automated Ordering: For stocks approved by AI, automated buying is executed without a 0.1-second hesitation through the KIS API.

  • Risk Management: It doesn't just buy; it calculates ATR volatility to set the optimal weight and entry price according to market conditions.

STEP 03. [Harvest]

Minute-by-minute close monitoring and dynamic take-profit/stop-loss

"While you sleep, the system works without a minute's rest to capture the optimal selling points."

  • Real-time Monitoring: Immediately after purchase, the system tracks price fluctuations every minute and activates a self-recovery mechanism.

  • Smart Selling: Instead of a fixed yield, it executes dynamic take-profit/stop-loss to maximize profits according to market movements, and immediately upon completion of the sale, it sends a notification with the final profit results and a message to cheer you on for the day.

🎨 Even stock beginners can "just follow along and be done"

  • PPT Supplemental Materials :

    • We have significantly reinforced the lecture materials by actively incorporating feedback from our students.


    • Designed with visual aids and infographics to make difficult stock concepts and financial indicators easy to understand

  • Step-by-Step Guide:

    • Complete a professional-level automated trading program just by clicking along as the instructor leads.

    • Since you only need to follow along, it is fully possible even if you have almost no coding experience.

    • I will show you exactly how to "vibe code" to meet your specific requirements.

This is how it differs from other auto-trading systems.

We recommend this to the following people.

I'm very interested in automated stock trading, but I'm worried about returns or stability. I recommend this to those who are disappointed with the common 'simple rule-based' automated trading on the market and now want to make institutional-grade sophisticated strategies their own.

I can't respond in real-time.
For those who want to stop worrying, "What if the system stops due to an error?" We have prepared this for those who want to achieve true 'pillow investment' through self-recovery logic and Slack reports.

Those who want to combine AI and finance.
Recommended for those who know the basics of Python but want to experience an advanced architecture that connects it to a practical profit-generating system.

Here is what you will learn.

Direct implementation of authentic technical indicators based on Wilder's Smoothing

Why should we use Wilder's smoothing instead of standard EMA? We will directly calculate RSI, ATR, and ADX using the same formulas as TradingView and Investing.com, and write authentic quant code that even removes ffill noise from weekends and public holidays.

ATR-based Dynamic Take-Profit/Stop-Loss + 4 Sell Triggers

Does it make sense to use the same % stop-loss for every stock when their volatility differs? We will implement a sophisticated liquidation algorithm that automatically calculates take-profit and stop-loss levels for each stock based on ATR (Average True Range) volatility, and combines four triggers—Dead Cross, RSI Overbought, MACD Sell, and Panic Sell—with ADX trend strength.

FastAPI Lifespan + APScheduler + Asyncio Multi-Scheduler

How can you run 5-minute buys, 1-minute sells, and daily ML training on Kaggle GPUs all simultaneously within a single process? We will build a 24/7 multi-scheduler infrastructure that operates without conflicts using FastAPI lifespan + APScheduler + asyncio + threading isolation.

AI Buy Agent (20-year Wall Street Persona)

Because leaving buy decisions entirely to AI is risky, the system includes a final verification step where the AI reviews buy candidates generated from quantitative data (Quant) from the perspective of a human trader. Safety is ensured through a Fail-Close approach that blocks trades if any issues arise.

🧐 Points to check for choosing a fail-proof automated trading course!


☝️ Does it have practical strategies and risk management logic?

Check whether you can systematically learn and apply institutional-grade quant strategies and 'multi-layered defense filters' for principal protection, going beyond simple buy and sell functions.


✌️ Does it become a complete system that runs 24/7, 365 days a year?

Check if you can build a complete program that doesn't stop at theory but can actually run 24/7 in practice—even with your PC turned off—regardless of your environment, whether it's Windows, Mac, or Linux.


👌 Can the system recover on its own when an error occurs?

Check if you can reliably implement 'self-recovery logic,' which allows the system to automatically retry and return to normal without stopping, even in unexpected situations like network or API errors.

📢 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 about topics not covered here, please feel free to leave them on the Q&A board at any time.

We will provide a kind and detailed response as soon as we check your inquiry!

💡 [Target Audience and Difficulty]

Q. I am a non-major who is new to programming and stock investing. Can I complete an automated trading system with this course?

A. Yes, it is absolutely possible! This course is a 'complete edition' designed to allow even coding beginners to build a system that can be put into practical operation immediately. To ensure that non-majors do not get exhausted by environment settings, we cover how to build a system without separate server costs or complex configurations. We have introduced the 'AI Vibe Coding' method, which uses AI to quickly solve problems and modify strategies even if you encounter unfamiliar code, so you don't have to worry about prior knowledge. You can run it immediately by using the full source code provided in the lecture, and we will support you through the Q&A board until the end if you get stuck.

Q. Can I take this course (Completion Edition) directly without taking the previous roadmap courses (Parts 1 and 2)?

A. Yes, you can take this course immediately and still successfully complete and operate the system. This course is designed as a practical, condensed version, boldly stripping away basic theories to focus on the outcome of "building a fully automated AI trading system and linking it to a real account." However, if you wish to gain a deep understanding of the foundational knowledge (such as FastAPI's operating principles or the mathematical principles of deep learning models) and build the expertise to customize the system freely according to market conditions, we recommend taking Parts 1 and 2 either concurrently or sequentially in the long term.

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

A. To help you learn market analysis and automated trading systematically with as little trial and error as possible until you build your own automated trading system, I have organized three lectures into one connected roadmap. Please refer to the guide below and choose 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

🛠️ [System Environment and Costs]

Q. Do I have to open a Korea Investment & Securities account? Can I use accounts from other brokerages (Mirae Asset, etc.)?

A. The practice sessions and automated trading integration logic of this course are designed based on the Korea Investment & Securities API. Therefore, a Korea Investment & Securities account is essential to fully utilize the course and run the program yourself. Since it is difficult to proceed with the practice using accounts from other securities firms, we recommend opening an account easily online (non-face-to-face) before participating.

Q. Do I have to use Claude for coding? I'm curious if I can use other AI tools and if there are any additional costs.

A. You are free to use any AI tools you are familiar with (Cursor, Codex, ChatGPT, etc.). Since the LLM itself does not account for an absolute portion of the automated trading system's structure, you can choose whichever tool you find most comfortable.

  • Additional program operating costs: There are no separate server maintenance costs, and the cost incurred when calling the API to analyze potential stocks for purchase is approximately 3,000 KRW per month on average. Since you are only charged for what you use, you can operate it lightly without much burden.

Q. In what format are the lecture materials provided?

A. Along with the PPT lecture materials, we provide all the completed source codes covered in the lectures. In particular, we have included detailed comments and conceptual explanations as Markdown files within the source code, allowing you to intuitively review, modify, and practice within the code window to suit your taste without having to search for other links.

📈 [Investment Targets and Scalability]

Q. Is this program only for U.S. stocks? Can it not be applied to Korean stocks or cryptocurrencies?

A. In the lecture, we use the 'Nasdaq Top 30' stocks as examples because they have overwhelming trading volume and high data reliability, allowing the AI to perform the most precise analysis. This is also to minimize execution errors (slippage) that occur during buying and selling. However, the framework of automated trading (strategy establishment, backtesting, order execution logic) applies identically to all markets worldwide. You can expand it as much as you like by simply changing the data source from the US market-based pipeline and adjusting conditions to fit specific rules for the Korean market (trading hours, price limits, etc.) or crypto exchange APIs. By utilizing the 'Vibe Coding' learned in the lecture, you can easily perform these modifications. (※ Due to many requests for a Korean market version, I am currently working hard to prepare a separate course dedicated to the Korean market!)

Q. Besides the top Nasdaq stocks, can I customize the stocks to my liking, such as discovering new promising stocks?

A. Yes, of course! In the latter part of the lecture, we will cover how to customize stocks using Claude Vibe coding. Through this, you can freely adjust not only the target stocks but also analysis indicators or condition scores as you wish to create your own "personalized automated trading system."

Q. Are there any additional costs or taxes when trading U.S. stocks?

A. When viewing real-time quotes through the Korea Investment & Securities API, you may need to apply for real-time market data services according to the brokerage's policy. Additionally, due to the nature of overseas stocks, currency exchange costs (spreads) and capital gains taxes based on annual profits may occur in addition to trading commissions. Therefore, we recommend verifying the system's stability first with small amounts or through mock investment before deciding on the scale of your actual investment.

🛡️ [Live Operation and Post-Management]

Q. Can the program I create actually generate profits? I'm curious about any verified cases.

A. This system contains risk management logic that I have personally researched over the past two years and am currently using in real-world operations. I disclose all operational cases and know-how within the lecture, including how the algorithm controlled risk and safely defended the account with a +1.48% return even during market crises such as the oil price surge and crash in March 2026.

Q. How can I check the reasons for the program's buy/sell decisions and the real-time return rate?

A. Even while the system is running automatically, you can monitor it perfectly in two ways.

  1. Trade Rationale Notifications: The program sends real-time notifications via the Slack app on your smartphone, providing specific reasons for why it bought or sold a particular stock.

  2. Real-time Returns: You can check your real-time account status and accurate returns at any time through the Korea Investment & Securities app where actual trading takes place.

Q. How can I get help if I encounter something I don't understand during the lecture?

A. If you encounter any difficulties during the course, please feel free to leave a message on the Q&A board at any time. We provide detailed answers as quickly as possible, and for errors that are difficult to resolve through text, we offer direct troubleshooting via remote support. We will do our best to help you complete your own system until the very end without falling behind.

(※ When asking a question, please specify the lecture title and timeline in detail so that we can provide a faster and more accurate response.)

    I purchased the course and spent the last two days studying hard to complete it. I plan to start mock trading this Monday. I should definitely check out the instructor's other lectures as well. I've become very interested in automated trading. Thank you for the great course.

    • cheatkeylab
      Instructor

      Hello, @byunbros. I applaud your passion and execution for focusing intensely over the short span of two days to complete the course and build your system. It is very rewarding to see that you aren't stopping at just finishing the lectures, but are immediately starting real-world verification through paper trading this coming Monday. The automated trading system implemented in this course was designed with somewhat conservative rule-based logic, prioritizing the protection of students' assets and stable build-up. As you proceed with paper trading, I encourage you to experience various market environments, such as bull and bear markets, and boldly try changing different parameters or trading conditions. Based on the framework of this course, I hope you evolve it into your own sophisticated trading engine by sometimes incorporating aggressive profit-seeking logic and tuning the numbers. The numerous tests and feedback data from paper trading will become your most powerful weapon in future live trading. If you have any questions or new ideas that arise while paper trading, please feel free to leave a question at any time. I will always be rooting for you. Thank you!

    I am finally leaving a proper review now. I have completed everything up to uploading to AWS as you updated, and the automated trading has been running for about two days. You explained everything so kindly and clearly, but the theoretical aspects of the stock market are still a bit difficult for me. I wanted to create a trading log, so I built one using Codex and have already implemented it. Just as you intended, I now plan to analyze and modify the algorithm little by little. Thank you for the great lecture, and I will be in touch if I have any questions.

    I'm currently working on the early stages, and for those who want to use various models, using the OpenRouter API will allow you to try out not only Claude but also several open-source models, so you'll be able to test a wide variety of options.
