 **Learning:** Adding color-coded indicators (Green/Red) and emojis (💰, 📉) in CLI tools significantly reduces cognitive load when parsing financial data streams. It transforms a wall of text into a scannable narrative.
 **Action:** For data-heavy CLI applications, always implement a semantic color system and visual anchors (icons/emojis) for key events.
 
-## 2024-05-23 - CLI Accessibility and Control
-**Learning:** While color and emojis enhance UX, they can be inaccessible (color blindness) or intrusive (automation logs). Providing `--no-color` and `--quiet` flags is essential for a robust CLI tool that respects user context and accessibility needs.
-**Action:** Always include flags to disable visual enhancements and suppress verbose output in CLI tools.
+## 2024-10-24 - CLI Accessibility and Control
+**Learning:** While colors improve scannability, they can be inaccessible or noisy in certain contexts. Users also need control over simulation parameters without modifying code.
+**Action:** Implement `--no-color` for accessibility and `--quiet` for reduced verbosity. Use `argparse` to expose key parameters like simulation duration and initial capital.
