Watchlists

In this example assume MyWatchlist is an exising watchlist we want to modify.

To use watchlists you’ll need a production session:

from tastytrade import Session
session = Session(user, password)

Now we can fetch the watchlist:

from tastytrade import Watchlist
watchlist = Watchlist.get_private_watchlist(session, 'MyWatchlist')
print(watchlist.watchlist_entries)

>>> [{'symbol': 'AAPL', 'instrument-type': 'Equity'}, {'symbol': 'MSFT', 'instrument-type': 'Equity'}]

To add a symbol to the watchlist:

from tastytrade.instruments import InstrumentType
Watchlist.add_symbol('SPY', InstrumentType.EQUITY)

In this case, the symbol is present locally, but not remotely, so we need to update the remote list:

watchlist.update_private_watchlist(session)

We can also create a new watchlist from scratch, then publish it to the Tastytrade server:

new_watchlist = Watchlist(name='NewWatchlist')
new_watchlist.add_symbol('USO', InstrumentType.EQUITY)
new_watchlist.upload_private_watchlist(session)
