instruments.Option.get_options no working

[hjnoble3]

I am looking for something similar like these for equity options:

`from tastytrade import instruments

cryptocurrency = instruments.Cryptocurrency.get_cryptocurrencies(session) future_options = instruments.FutureOptionProduct.get_future_option_products(session) `

It looks like the following was suppose to do the desired function but results in error. options = instruments.Option.get_options(session)

I have run the corresponding Postman provided by Tasty which also errors:

I have reached out to Tasty to see what is happening in Postman about 2 weeks ago and have not heard anything.

Does anyone know a work around?

I ultimately plan to use the information to filter down to underlying I am interested in trading based on things like finances (pulled from yahoo), number of expiration between two dates, and average slippage and open interest per options contract.

I see that in the documentation that passing a list of symbols is optional, though from this is looks like it's required. I think that makes sense though, I mean it's kinda ambiguous what should happen if you don't pass any symbols in... There's hundreds of thousands of options contracts out there! If you call Option.get_options make sure to pass in the symbols you want. Here's the relevant docs: https://tastyworks-api.readthedocs.io/en/latest/tastytrade.html#tastytrade.instruments.Option.get_options

If you're looking for a specific underlying, what you want is probably get_option_chain, which you can read about here: https://tastyworks-api.readthedocs.io/en/latest/tastytrade.html#tastytrade.instruments.get_option_chain

Thanks for the quick reply.

from tastytrade import instruments options = instruments.Option.get_options(session, ['SPY', 'TSLA', 'LULU']) results in an empty list. So does: options = instruments.Option.get_options(session, 'SPY')

Tasty also replayed today as well and said a symbol is needed or else the GET will timeout.

I tried adding a symbol in Postman and it returns an empty list as well, so it does not seem to be an issue with python.

Tasty recommended using GET /option-chains/:symbol/nested which is equivalent to instruments.NestedOptionChain.get_chain().

Since instruments.Option.get_options() is functioning as expected in Postman should I close this, or leave it open since I do not know why blank lists are returned in Postman?

Option.get_options is for options symbols, not stock symbols. So something like "AAPL 220617P00150000" instead of "SPY" would work. If you want the options symbols associated with an underlying, use get_option_chain. You can read about symbology here: https://developer.tastytrade.com/#tastytrade-symbology

That makes sense and works.

Thanks for the help!
