Conversion document?

[wayne47git]

Installed this package in 2024 and developed a lot of code on top of it. Working great so far.

Tasty converted to Oauth2 and, apparently. the version of code I had installed does not support 2FA.
Today, Tasty stopped supporting the old login/password system.
So I spun up a new virtual environment and installed the current version.

Is there a document somewhere that describes what needs to be converted? So far I have:
get_market_metrics can no longer be imported from tastytrade I'm just removing it for now, not sure if that will work?
EventType can not longer be imported from tastytrade.dxfeed Again, I just removed it

The session appears to be created correctly but, apparently, streamer creation has changed as this no longer works:

streamer = await DXLinkStreamer.create(session)
                     ^^^^^^^^^^^^^^^^^^^^^
AttributeError: type object 'DXLinkStreamer' has no attribute 'create'

Not sure how to proceed from here or what other issues I will encounter.

Is there some documentation on doing the conversion?

Not exactly a conversion document but you can go through the release descriptions: https://github.com/tastyware/tastytrade/releases

get_market_metrics is now in tastytrade.metrics. EventType was internal so not sure what you need it for. Streamers need to be used with the async context manager now:

async with DXLinkStreamer(session) as streamer:
    ...

The docs here: https://tastyworks-api.readthedocs.io/en/latest/ should always be up to date

Thanks, I'll go read that
Looking at Watchlist docs, Something is off:
from tastytrade import PrivateWatchlist, PublicWatchlist
Returns
ImportError: cannot import name 'PrivateWatchlist' from 'tastytrade'

PublicWatchlist fails too

Good catch, I will update that. You should be able to import them from tastytrade.watchlist.

BTW the tt example program fails too:
./tt option strangle SPY -1 --delta 16

Thanks for the pointers. the changes from BidPrice to bid_price (and similar) took as while but I have it running.

Really appreciate your efforts.. Now, just need the market to keep recovering a bit

The CLI is definitely out of date, I haven't gotten around to updating it yet
