     * Signed returns with color coding
     * Ensemble summary (threshold + active models)

================================================================================
COLOR CODING RULES
================================================================================

Confidence Levels:
- High (≥80%):   Green   - High confidence predictions
- Medium (60-79%): Yellow - Moderate confidence
- Low (<60%):    Red     - Low confidence (caution)

Trading Actions:
- BUY:           Green   - Bullish signal
- SELL:          Red     - Bearish signal
- HOLD:          Yellow  - Neutral signal

Performance Metrics:
- Accuracy:      Green (≥70%), Yellow (≥60%), Red (<60%)
- Sharpe Ratio:  Green (≥1.5), Yellow (≥1.0), Red (<1.0)
- Returns:       Sign-prefixed (+/-) with color coding
- Drawdown:      Percentage format (negative values)

Model Types:
- Ensemble:      Yellow  - Multi-model voting
- Single Model:  Blue    - Individual (DQN/PPO/MAMBA2/TFT)

================================================================================
UNIT TESTS (3 tests)
================================================================================

1. test_format_ml_order_submission() - Lines 927-942
   - Tests order submission formatting
   - Verifies no panics on valid input

2. test_format_ml_predictions() - Lines 944-970
   - Tests prediction history with 2 sample predictions
   - Verifies table rendering with positive/negative returns

3. test_format_ml_performance() - Lines 972-1001
   - Tests performance metrics with 2 models
   - Verifies accuracy, Sharpe ratio, ensemble summary

TECHNICAL NOTES
================================================================================

Import Patterns:
use comfy_table::{Table, Cell, Color, Attribute};
use owo_colors::OwoColorize as _;

Color Method Usage (owo-colors):
"text".green()         // Green text
"text".bold()          // Bold text
"text".cyan().bold()   // Cyan + bold

Cell Color Usage (comfy-table):
Cell::new("text").fg(Color::Green)  // Green cell
Cell::new("text").fg(Color::Cyan)   // Cyan cell

Table Creation:
let mut table = Table::new();
table.set_header(vec![Cell::new("Header").fg(Color::Cyan)]);
table.add_row(vec![Cell::new("Data")]);
println!("{table}");
