Pair trades order

[BRBroadgate]

How does one create a pair trade? When using the platform, it is defined as a Complex order. However, when using the API, I can't find the correct way to formulate it. Can someone help me?

Thanks in advance

Check out the documentation there. OCO doesn't seem to work for Debit orders though.

Try placing a pairs trade on the platform, then fetching your complex order history and copy the structure you see there.

Pair trades use a single NewOrder with multiple legs:

from decimal import Decimal
from tastytrade import Session, Account
from tastytrade.instruments import Equity
from tastytrade.order import NewOrder, OrderAction, OrderTimeInForce, OrderType

session = Session('client_secret', 'refresh_token')
account = Account.get(session)[0]

# Get both symbols
symbol1 = Equity.get(session, 'SPY')
symbol2 = Equity.get(session, 'QQQ')

# Build legs for the pair
leg1 = symbol1.build_leg(Decimal('100'), OrderAction.BUY_TO_OPEN)
leg2 = symbol2.build_leg(Decimal('100'), OrderAction.SELL_TO_OPEN)

# Create pair order
order = NewOrder(
    time_in_force=OrderTimeInForce.DAY,
    order_type=OrderType.LIMIT,
    legs=[leg1, leg2],  # Both legs execute together
    price=Decimal('-50.00')  # Net debit (negative) or credit (positive)
)

# Place order
response = account.place_order(session, order, dry_run=True)
