tastytrade 5.1

An unofficial SDK for Tastytrade!

Tastytrade Python SDK

A simple, reverse-engineered SDK for Tastytrade built on their (mostly) public API. This will allow you to create trading algorithms for whatever strategies you may have quickly and painlessly in Python.

Installation

$ pip install tastytrade

Creating a session

A session object is required to authenticate your requests to the Tastytrade API. You can create a real session using your normal login, or a certification (test) session using your certification login.

from tastytrade.session import Session
session = Session('username', 'password')

Using the streamer

The streamer is a websocket connection to the Tastytrade API that allows you to subscribe to real-time data for Quotes, Greeks, and more.

from tastytrade.streamer import DataStreamer, EventType

streamer = await DataStreamer.create(session)
subs_list = ['SPY', 'SPX']

# this function fetches quotes once, then closes the subscription
quotes = await streamer.oneshot(EventType.QUOTE, subs_list)
print(quotes)

>>> [Quote(eventSymbol='SPY', eventTime=0, sequence=0, timeNanoPart=0, bidTime=0, bidExchangeCode='Q', bidPrice=411.58, bidSize=400.0, askTime=0, askExchangeCode='Q', askPrice=411.6, askSize=1313.0), Quote(eventSymbol='SPX', eventTime=0, sequence=0, timeNanoPart=0, bidTime=0, bidExchangeCode='\x00', bidPrice=4122.49, bidSize='NaN', askTime=0, askExchangeCode='\x00', askPrice=4123.65, askSize='NaN')]

Getting current positions

from tastytrade.account import Account

account = Account.get_accounts(session)[0]
positions = account.get_positions(session)
print(positions[0])

>>> CurrentPosition(account_number='5WV69754', symbol='IAU', instrument_type=<InstrumentType.EQUITY: 'Equity'>, underlying_symbol='IAU', quantity=Decimal('20'), quantity_direction='Long', close_price=Decimal('37.09'), average_open_price=Decimal('37.51'), average_yearly_market_close_price=Decimal('37.51'), average_daily_market_close_price=Decimal('37.51'), multiplier=1, cost_effect='Credit', is_suppressed=False, is_frozen=False, realized_day_gain=Decimal('7.888'), realized_day_gain_effect='Credit', realized_day_gain_date=datetime.date(2023, 5, 19), realized_today=Decimal('0.512'), realized_today_effect='Debit', realized_today_date=datetime.date(2023, 5, 19), created_at=datetime.datetime(2023, 3, 31, 14, 38, 32, 58000, tzinfo=datetime.timezone.utc), updated_at=datetime.datetime(2023, 5, 19, 16, 56, 51, 920000, tzinfo=datetime.timezone.utc), mark=None, mark_price=None, restricted_quantity=Decimal('0'), expires_at=None, fixing_price=None, deliverable_type=None)

Symbol search

from tastytrade.search import symbol_search

results = symbol_search(session, 'AAP')
print(results)

>>> [SymbolData(symbol='AAP', description='Advance Auto Parts Inc.'), SymbolData(symbol='AAPD', description='Direxion Daily AAPL Bear 1X Shares'), SymbolData(symbol='AAPL', description='Apple Inc. - Common Stock'), SymbolData(symbol='AAPB', description='GraniteShares 1.75x Long AAPL Daily ETF'), SymbolData(symbol='AAPU', description='Direxion Daily AAPL Bull 1.5X Shares')]

Placing an order

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

account = Account.get_account(session, '5WV69754')
symbol = Equity.get_equity(session, 'USO')
leg = symbol.build_leg(Decimal('5'), OrderAction.BUY_TO_OPEN)  # buy to open 5 shares

order = NewOrder(
   time_in_force=OrderTimeInForce.DAY,
   order_type=OrderType.LIMIT,
   legs=[leg],  # you can have multiple legs in an order
   price=Decimal('50'),  # limit price, here $50 for 5 shares = $10/share
   price_effect=PriceEffect.DEBIT
)
