## 🚀 Quick Start

### Basic Setup

```python
import asyncio
from alpacafarmer import AlpacaAuth, TraderClient, Environment

async def main():
    # Initialize authentication
    auth = AlpacaAuth(
        api_key="your-api-key",
        api_secret="your-api-secret",
        environment=Environment.PAPER  # Use LIVE for production
    )
    
    # Use the client with async context manager
    async with TraderClient(auth) as client:
        account = await client.get_account()
        print(f"Account ID: {account.id}")
        print(f"Buying Power: ${account.buying_power}")
        print(f"Portfolio Value: ${account.portfolio_value}")

asyncio.run(main())
```

### Using Environment Variables

```bash
export ALPACA_API_KEY="your-api-key"
export ALPACA_SECRET_KEY="your-api-secret"
```

```python
from alpacafarmer import AlpacaAuth, TraderClient

# Credentials loaded automatically from environment
auth = AlpacaAuth()
```

---

## 📈 TraderClient API

The `TraderClient` is for individual traders using Alpaca's Trading API.

### Getting Account Information

```python
from alpacafarmer import AlpacaAuth, TraderClient

async with TraderClient(AlpacaAuth()) as client:
    # Get account details
    account = await client.get_account()
    
    print(f"Cash: ${account.cash}")
    print(f"Buying Power: ${account.buying_power}")
    print(f"Day Trading BP: ${account.daytrading_buying_power}")
    print(f"Pattern Day Trader: {account.pattern_day_trader}")
```

### Creating Orders

```python
from alpacafarmer import (
    AlpacaAuth, TraderClient, OrderRequest,
    OrderSide, OrderType, TimeInForce
)

async with TraderClient(AlpacaAuth()) as client:
    # Market order
    market_order = await client.create_order(OrderRequest(
        symbol="AAPL",
        qty=10,
        side=OrderSide.BUY,
        type=OrderType.MARKET,
        time_in_force=TimeInForce.DAY
    ))
    print(f"Market Order ID: {market_order.id}")
    
    # Limit order
    limit_order = await client.create_order(OrderRequest(
        symbol="MSFT",
        qty=5,
        side=OrderSide.BUY,
        type=OrderType.LIMIT,
        time_in_force=TimeInForce.GTC,
        limit_price=350.00
    ))
    print(f"Limit Order ID: {limit_order.id}")
    
    # Stop-loss order
    stop_order = await client.create_order(OrderRequest(
        symbol="GOOGL",
        qty=2,
        side=OrderSide.SELL,
        type=OrderType.STOP,
        time_in_force=TimeInForce.GTC,
        stop_price=140.00
    ))
    print(f"Stop Order ID: {stop_order.id}")
    
    # Notional order (dollar amount instead of shares)
    notional_order = await client.create_order(OrderRequest(
        symbol="TSLA",
        notional=1000.00,  # Buy $1000 worth
        side=OrderSide.BUY,
        type=OrderType.MARKET,

    # Replace/modify an order
    updated_order = await client.replace_order(
        order_id="order-id",
        request=OrderUpdate(
            qty=15,
            limit_price=355.00
        )
    )
    
    # Cancel an order
    await client.cancel_order("order-id")
    
    # Cancel all orders

    # Get specific position
    aapl_position = await client.get_position("AAPL")
    
    # Close a position completely
    close_order = await client.close_position("AAPL")
    
    # Close partial position (by quantity)
    partial_close = await client.close_position("MSFT", qty=Decimal("5"))
    
    # Close partial position (by percentage)
    half_close = await client.close_position("GOOGL", percentage=Decimal("50"))

## 🏗️ Pydantic Models

AlpacaFarmer provides 35+ Pydantic models for complete type safety and validation.

### Key Models

| Category | Models |
|----------|--------|
| **Account** | `Account`, `AccountConfiguration` |
| **Orders** | `OrderRequest`, `Order`, `OrderUpdate`, `ListOrdersRequest` |
| **Positions** | `Position`, `ListPositionsRequest` |
| **Assets** | `Asset`, `ListAssetsRequest` |
| **Market Data** | `Bar`, `Quote`, `Trade`, `Snapshot`, `BarsRequest`, `QuotesRequest`, `TradesRequest` |

| **Transfers** | `Transfer`, `TransferRequest`, `ACHRelationship`, `ACHRelationshipRequest` |
| **Journals** | `Journal`, `JournalRequest` |

### Validation Example

```python
from pydantic import ValidationError
from alpacafarmer import OrderRequest, OrderSide, OrderType, TimeInForce

# Validation catches errors before API calls
try:
    order = OrderRequest(
        symbol="",  # Invalid: empty symbol
        qty=-10,    # Invalid: negative quantity
        side=OrderSide.BUY,
        type=OrderType.MARKET,
        time_in_force=TimeInForce.DAY
    )
except ValidationError as e:
    print("Validation errors:")
    for error in e.errors():
        print(f"  {error['loc']}: {error['msg']}")
```

### Type-Safe Enums

```python
from alpacafarmer import (
    OrderSide, OrderType, TimeInForce, OrderStatus,
    AssetClass, AssetStatus, PositionSide, AccountStatus,
    Timeframe, DataFeed,
    TransferDirection, TransferType, TransferStatus,
    BankAccountType, JournalEntryType, JournalStatus,
    FundingSource, TaxIdType

AlpacaFarmer provides typed exceptions for all error scenarios:

```python
from alpacafarmer import (
    AlpacaError,
    APIError,
    AuthenticationError,
    RateLimitError,
    ValidationError,
    TraderClient,
    AlpacaAuth
)

async with TraderClient(AlpacaAuth()) as client:
    try:
        account = await client.get_account()
        
    except AuthenticationError as e:
        # Invalid or missing API credentials
        print(f"Auth failed: {e.message}")
        
    except RateLimitError as e:
        # API rate limit exceeded
        print(f"Rate limited: {e.message}")
        if e.retry_after:
            print(f"Retry after {e.retry_after} seconds")
            
    except APIError as e:
        # HTTP API error with status code
        print(f"API Error [{e.status_code}]: {e.message}")
        print(f"Response: {e.response_body}")
        
    except ValidationError as e:
        # Request validation failed
        print(f"Validation failed: {e.message}")
        for error in e.errors:
            print(f"  - {error}")
