StockRulebook Invest Journal
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.
