Core API Methods

1. Place Order

Place a single order with full control over parameters:

response = client.placeorder(
    strategy="MyStrategy",
    symbol="RELIANCE",
    action="BUY",
    exchange="NSE",
    price_type="MARKET",
    product="MIS",
    quantity=1
)
# Response: {'orderid': '250408000989443', 'status': 'success'}

Limit Order Example:

response = client.placeorder(
    strategy="MyStrategy",
    symbol="YESBANK",
    action="BUY",
    exchange="NSE",
    price_type="LIMIT",
    product="MIS",
    quantity=1,
    price=16.50,
    trigger_price=0,
    disclosed_quantity=0
)

Stop Loss Order Example:

response = client.placeorder(
    strategy="MyStrategy",
    symbol="SBIN",
    action="SELL",
    exchange="NSE",
    price_type="SL",
    product="MIS",
    quantity=10,
    price=750,           # Limit price
    trigger_price=752    # Trigger price
)

2. Smart Order (Position-Aware)

Automatically adjusts order quantity based on current position:

response = client.placesmartorder(
    strategy="SmartBot",
    symbol="TATAMOTORS",
    action="SELL",
    exchange="NSE",
    price_type="MARKET",
    product="MIS",
    quantity=1,
    position_size=5  # Desired final position
)
# If current position is 0, sells 5 to reach -5
# If current position is 3, sells 8 to reach -5

Use Cases:

• Rebalancing: Set position_size to target position
• Reversal: Set action opposite to current direction
• Scale-in/out: Adjust quantity dynamically

3. Basket Order

Execute multiple orders simultaneously:

basket_orders = [
    {
        "symbol": "INFY",
        "exchange": "NSE",
        "action": "BUY",
        "quantity": 1,
        "pricetype": "MARKET",
        "product": "MIS"
    },
    {
        "symbol": "TCS",
        "exchange": "NSE",
        "action": "BUY",
        "quantity": 1,
        "pricetype": "MARKET",
        "product": "MIS"
    },
    {
        "symbol": "WIPRO",
        "exchange": "NSE",
        "action": "BUY",
        "quantity": 1,
        "pricetype": "MARKET",
        "product": "MIS"
    }
]

response = client.basketorder(orders=basket_orders)
# Response includes status for each order

4. Split Order

Break large orders into smaller chunks to avoid market impact:

response = client.splitorder(
    symbol="YESBANK",
    exchange="NSE",
    action="SELL",
    quantity=500,
    splitsize=100,  # Each order will be max 100
    price_type="MARKET",
    product="MIS"
)
# Creates 5 orders of 100 each

Response:

{
  "status": "success",
  "split_size": 100,
  "total_quantity": 500,
  "results": [
    {"order_num": 1, "orderid": "123", "quantity": 100, "status": "success"},
    {"order_num": 2, "orderid": "124", "quantity": 100, "status": "success"},
    ...
  ]
}

Common Patterns

Intraday Scalping

# Entry
entry = client.placeorder(
    strategy="Scalper",
    symbol="SBIN",
    action="BUY",
    exchange="NSE",
    price_type="MARKET",
    product="MIS",
    quantity=100
)

# Exit with profit target (use limit order)
exit_order = client.placeorder(
    strategy="Scalper",
    symbol="SBIN",
    action="SELL",
    exchange="NSE",
    price_type="LIMIT",
    product="MIS",
    quantity=100,
    price=current_price * 1.005  # 0.5% profit
)

Swing Trading Entry

response = client.placeorder(
    strategy="SwingTrader",
    symbol="TATASTEEL",
    action="BUY",
    exchange="NSE",
    price_type="LIMIT",
    product="CNC",  # Delivery
    quantity=10,
    price=150.00
)

Risk Management - Stop Loss

# Place stop loss immediately after entry
sl_order = client.placeorder(
    strategy="Scalper",
    symbol="SBIN",
    action="SELL",
    exchange="NSE",
    price_type="SL-M",
    product="MIS",
    quantity=100,
    trigger_price=entry_price * 0.995  # 0.5% stop loss
)

Error Handling

response = client.placeorder(...)

if response.get('status') == 'success':
    print(f"Order placed: {response['orderid']}")
else:
    print(f"Error: {response.get('message', 'Unknown error')}")

Notes

• Always verify OPENALGO_API_KEY is set before trading
• Use MIS for intraday, CNC/NRML for positional trades
• Test with small quantities first
• Use Analyzer mode for paper trading: client.analyzertoggle(mode=True)
