Track trades & Refine rules

Free · In-App Purchases · Designed for iPad

Stock Rulebook is an app designed to help you organize, record, and analyze your investment “rules” and “policies.” It’s built to help you stay true to your own investment philosophy—without being swayed by noise or complexity. ■ Key Features 1. Manage Your Investment Rules & Policies Record your principles systematically — such as “buy timing,” “sell timing,” “anomalies,” “chart patterns,” and “stop-loss criteria.” Includes around 300 preloaded investment rules as examples to start with. You can freely add your own original rules as well. Tags and notes make it easy to organize and customize your personal rulebook. 2. Link Rules to Your Trades When you buy or sell a stock, record which rule guided your decision. The app automatically aggregates the performance of each rule, letting you see which strategies truly worked. You can also leave qualitative notes for each trade—capturing your thoughts and emotions behind the decision. 3. Investment Journal & Review Use the built-in “Journal” tab to quickly log your daily investment actions and reflections. Easily review data such as purchase amount, sell amount, and profit/loss results at a glance. Browse your past entries to refine your investment approach and improve over time. 4. Rule & Policy Search The Home tab allows you to instantly search through all your rules and policies. Pin frequently used or important ones for quick access—so your investment decisions always stay grounded in your principles. 5. Investment Performance Summary Automatically categorizes effective and ineffective rules, and displays them in a clean, simple summary. Visually grasp which rules are driving results. By quantifying performance, you can move away from emotional trading and toward data-driven consistency. ■ The Philosophy Behind This App Stock Rulebook is not just a note-taking tool. It’s a thinking companion—built to help you reflect objectively on your past decisions and refine your future ones. Hold on to your unique investment principles. Build unshakable consistency. This is the most elegant, minimal, and effective way to do so. ■ Ideal For Investors who want to define and organize their investment rules Those who want to review past trades systematically Anyone seeking to analyze the causes of success and failure Traders who want to avoid emotional decisions People who want to shape their own investment philosophy ■ Recommended For Beginners just starting out in stock investing Investors who feel their decision-making has been inconsistent Those experimenting with different trading styles Anyone who wants to systematize their personal rules ■ Summary Stock Rulebook is an app that helps you uphold the most essential principle in investing: consistency.
