        },
        token="your-jwt-auth-token"
    )
    
    # Real-time quotes
    def on_quote(q):
        print(f"{q['symbol']}: {q['bid']}/{q['ask']}")
    
    platform.emitter.on('quote', on_quote)
    
    # Trade events
    def on_trade(e):
        d = e['data']
        cmd = 'BUY' if d['cmd'] == 0 else 'SELL'
        print(f"#{d['order']} {cmd} {d['volume']} {d['symbol']}")
    
    platform.emitter.on('trade:event', on_trade)
    
    # Subscribe to new symbol

    # Create user
    await platform.add_user(
        name='John Doe',
        group='VIP',
        leverage=500,

## Examples

### Subscribe & Unsubscribe

```python
# Single symbol
resp = await platform.subscribe('GBPUSD')
print(f"Subscribed: {resp}")

# Multiple symbols
await platform.subscribe(['GBPUSD', 'USDJPY'])

# Unsubscribe
await platform.unsubscribe('BTCUSD')
```

### Get All Users

```python
try:
    resp = await platform.call('GetUsers', {})
    print(f"Users: {resp}")
except Exception as e:
    print(f"Error: {e}")
```

### Listen to Balance Changes

```python
def on_balance(e):
    d = e['data']
    print(f"User {d['login']}: Equity = {d['equity']}")

platform.emitter.on('balance:event', on_balance)

# Listen to specific user
platform.emitter.on('balance:event:12345', lambda e: print("User 12345 balance updated"))
```

### Per-Symbol Quote Listener

```python
# Listen to specific symbol
def on_eurusd(q):
    print(f"EUR/USD: {q['bid']}")

platform.emitter.on('quote:EURUSD', on_eurusd)

# Listen to all quotes
def on_all_quotes(q):
    print(f"{q['symbol']}: {q['bid']}/{q['ask']}")

platform.emitter.on('quote', on_all_quotes)
```

### Handle Notifications

```python
def on_notify(n):
    level_map = {10: 'INFO', 20: 'WARN', 30: 'ERROR', 40: 'PROMO'}
    level = level_map.get(n['level'], str(n['level']))
    print(f"[{level}] {n['message']}")

platform.emitter.on('notify', on_notify)

# Listen to specific level
def on_error(n):
    print(f"ERROR: {n['message']}")

platform.emitter.on('notify:30', on_error)
```

### Symbol & Group Events

```python
# Symbol updates (spread, swap, etc.)
def on_symbol(e):
    d = e['data']
    print(f"Symbol {d['symbol']} updated: spread={d.get('spread', 'N/A')}")

platform.emitter.on('symbol:event', on_symbol)

# Group updates
def on_group(e):
    d = e['data']
    print(f"Group {d['group']}: leverage={d.get('default_leverage')}")

platform.emitter.on('group:event', on_group)
```

### Async Event Handlers

```python
# Event handlers can be async
async def on_trade(e):
    d = e['data']
    # Do async operations
    await some_async_function(d['order'])

platform.emitter.on('trade:event', on_trade)
```

### Full Example

## Configuration

### Options

```python
options = {
    'auto_subscribe': ['EURUSD', 'GBPUSD'],  # Auto-subscribe on connect
    'ignore_events': False,                   # Disable all event emission
    'prefix': 'nor',                          # Event prefix (reserved)
    'mode': 'live'                            # Environment: 'live' or 'demo'
}

platform = NTPlatform(
    "broker.nordentrader.com:8080",
    "my-bot",
    options=options,
    token="your-jwt-token"
)
```

---

## Error Handling

```python
try:
    resp = await platform.call('AddUser', {'name': 'John'})
    if 'error' in resp:
        print(f"Error: {resp['error']}")
    else:
        print(f"Success: {resp}")
except TimeoutError as e:
    print(f"Request timeout: {e}")
except ConnectionError as e:
    print(f"Not connected: {e}")
except Exception as e:
    print(f"Unexpected error: {e}")
```

## Asyncio Integration

### Running with Other Tasks

```python
async def main():
    platform = NTPlatform(...)
    
    # Run multiple tasks concurrently
    await asyncio.gather(
        platform.subscribe('EURUSD'),
        platform.get_users(),
        my_other_task()
    )
```

### Background Tasks

```python
async def price_monitor():
    while True:
        await asyncio.sleep(1)
        # Do something

async def main():
    platform = NTPlatform(...)
    
    # Start background task
    task = asyncio.create_task(price_monitor())
    
    # Keep running
    await asyncio.sleep(3600)
    
    # Cleanup
    task.cancel()
    platform.destroy()
```
