## 🚀 Quick Start

```python
from openstoxlify import fetch, plot, draw
from openstoxlify.models import Period, Provider

# 1. Get market data
data = fetch("AAPL", Provider.YFinance, Period.DAILY)

# 2. Plot closing prices
for quote in data.quotes:
    plot(PlotType.LINE, "Close", quote.timestamp, quote.close)

# 3. Visualize
draw()
```

## 🎨 Visualization with `draw()`

The `draw()` function generates professional financial charts combining:

- Price data (OHLC candles)
- Technical indicators
- Trading signals
- Custom annotations

### Basic Usage

```python
from openstoxlify import draw

# After plotting data and strategy signals:
draw()  # Displays interactive matplotlib chart
```

### Full Customization Example

```python
draw(
    show_legend=True,             # Toggle legend visibility
    figsize=(16, 9),              # Larger figure size
    offset_multiplier=0.03,       # Adjust trade marker positions
    rotation=45,                  # X-axis label rotation
    title="Custom Strategy Backtest",
    xlabel="Trading Days",
    ylabel="Price (USD)",
    candle_linewidth=0.8,         # Wick thickness
    candle_body_width=3,          # Body thickness
    marker_size=10,               # Trade signal markers
    annotation_fontsize=8,        # Trade annotation text
    histogram_alpha=0.7,          # Histogram transparency
    area_alpha=0.4,               # Area plot transparency
    line_width=2.5                # Trend line thickness
)

### Chart Features

| Element          | Description                         | Example Visual    |
| ---------------- | ----------------------------------- | ----------------- |
| **Candlesticks** | Green/red based on price direction  | 🟩🟥                |
| **Signals**      | Annotated markers for trades        | ▲ LONG<br>▼ SHORT |
| **Indicators**   | Lines, histograms, and filled areas | ─────             |

### Customization Options

```python
# Configure before calling draw()
plt.rcParams.update({
    'figure.figsize': (14, 7),       # Larger canvas
    'lines.linewidth': 2,            # Thicker trend lines
    'font.size': 10                  # Larger annotations
})

draw()  # Now with custom styling
```

### Example Output

![Sample Chart](public/images/ma_chart.png)
*(Actual chart would show:)*

- Price candles with volume
- SMA lines in different colors
- Triangle markers for entry/exit points
- Strategy annotations with position sizes

### Advanced Features

1. **Multi-panel Layouts**:

```python
# Create subplots
fig, (ax1, ax2) = plt.subplots(2, 1, height_ratios=[3,1])

# Price chart
draw(ax=ax1)  

# Volume histogram 
plot_volume(ax=ax2)  # Your custom function
plt.show()
```

2. **Save to File**:

```python
draw()
plt.savefig('strategy_backtest.png', dpi=300)
```

## 📚 Example Strategies

### Moving Average Crossover

```python
def ma_crossover(symbol: str, fast: int, slow: int):
    data = fetch(symbol, Period.DAILY)
    closes = [q.close for q in data.quotes]
    
    for i in range(slow, len(closes)):
        fast_ma = sum(closes[i-fast:i])/fast
        slow_ma = sum(closes[i-slow:i])/slow
        
        if fast_ma > slow_ma:
            act(ActionType.LONG, data.quotes[i].timestamp)
        else:
            act(ActionType.SHORT, data.quotes[i].timestamp)
```

## 💡 Tips

1. Use `output()` to export results for backtesting
2. Combine multiple plot types for rich analysis
3. All timestamps are timezone-aware UTC
