-## 2024-05-22 - Visual Hierarchy in CLI Output
-**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.
+## 2024-05-22 - Signal vs Noise in CLI Logs
+**Learning:** Users running simulations care about *events*, not *progress*. A daily log of "nothing happened" drowns out critical Buy/Sell signals.
+**Action:** For event-driven CLIs, suppress "heartbeat" logs. Highlight state changes with colors/icons to improve scanability.

-# Bitcoin Trading Simulation
-
-A Python-based CLI tool that simulates Bitcoin trading using a 'Golden Cross' moving average strategy. It generates synthetic price data using Geometric Brownian Motion, executes trades based on technical indicators, and provides a daily ledger with a final performance summary.
-
-## Features
-
-- **Price Simulation:** Uses Geometric Brownian Motion to simulate Bitcoin prices.
-- **Trading Strategy:** Implements a Golden Cross strategy (Short MA > Long MA = Buy, Short MA < Long MA = Sell).
-- **Rich CLI Output:** Features color-coded logs (Green for Buy/Profit, Red for Sell/Loss) and emojis for better readability.
-- **Performance metrics:** Compares the strategy's performance against a "Buy and Hold" approach.
-- **Customizable:** Configure simulation parameters via command-line arguments.
-
-## Installation
-
-1. Clone the repository.
-2. Install the required dependencies:
-
-```bash
-pip install -r requirements.txt
-```
-
-## Usage
-
-Run the simulation script with default settings (60 days, $10k initial cash):
-
-```bash
-python bitcoin_trading_simulation.py
-```
-
-### Options
-
-Customize the simulation with the following arguments:
-
-```bash
-python bitcoin_trading_simulation.py --days 100 --initial-cash 5000 --initial-price 60000 --volatility 0.03
-```
-
-- `--days`: Number of days to simulate (default: 60)
-- `--initial-cash`: Initial cash amount (default: 10000)
-- `--initial-price`: Initial Bitcoin price (default: 50000)
-- `--volatility`: Price volatility (default: 0.02)
-- `--quiet`: Suppress daily portfolio log (only show final result)
-- `--no-color`: Disable colored output (for accessibility or logging)
-
-Example:
-```bash
-python bitcoin_trading_simulation.py --days 30 --quiet --no-color
-```
-
-## Tests
-
-Run the test suite using `pytest`:
-
-```bash
-pytest
-```
