Places a market order for options (single or multi-leg) and returns the order details.
Supports up to 4 legs for multi-leg orders.
Single vs Multi-Leg Orders:
- Single-leg: One option contract (buy/sell call or put). Uses "simple" order class.
- Multi-leg: Multiple option contracts executed together as one strategy (spreads, straddles, etc.). Uses "mleg" order class.
API Processing:
- Single-leg orders: Sent as standard MarketOrderRequest with symbol and side
- Multi-leg orders: Sent as MarketOrderRequest with legs array for atomic execution
Args:
legs (List[Dict[str, Any]]): List of option legs, where each leg is a dictionary containing:
- symbol (str): Option contract symbol (e.g., 'AAPL230616C00150000')
- side (str): 'buy' or 'sell'
- ratio_qty (int): Quantity ratio for the leg (1-4)
order_class (Optional[Union[str, OrderClass]]): Order class ('simple', 'bracket', 'oco', 'oto', 'mleg' or OrderClass enum)
Defaults to 'simple' for single leg, 'mleg' for multi-leg
quantity (int): Base quantity for the order (default: 1)
time_in_force (Union[str, TimeInForce]): Time in force for the order. For options trading,
only 'day' is supported (default: 'day')
extended_hours (bool): Whether to allow execution during extended hours (default: False)
Returns:
str: Formatted string containing order details or error message
Examples:
# Single-leg: Buy 1 call option
legs = [{"symbol": "AAPL230616C00150000", "side": "buy", "ratio_qty": 1}]
# Multi-leg: Bull call spread (executed atomically)
legs = [
{"symbol": "AAPL230616C00150000", "side": "buy", "ratio_qty": 1},
{"symbol": "AAPL230616C00160000", "side": "sell", "ratio_qty": 1}
]
Note:
Some option strategies may require specific account permissions:
- Level 1: Covered calls, Covered puts, Cash-Secured put, etc.
- Level 2: Long calls, Long puts, cash-secured puts, etc.
- Level 3: Spreads and combinations: Butterfly Spreads, Straddles, Strangles, Calendar Spreads (except for short call calendar spread, short strangles, short straddles)
- Level 4: Uncovered options (naked calls/puts), Short Strangles, Short Straddles, Short Call Calendar Spread, etc.
