get_quotes does not work for options

[dougbrowning]

When using option symbols get_quotes returns {}. Using the symbol works in TOS so not sure why a quote will not come back?

TDSession.get_quotes(instruments=[".SPY210630C427"])
{}

Thanks

Well after building my own option parser I found the symbol tag in there. Turns out all you have to do is format it a little differently. Why TD has TOS and the API be slightly diff is beyond me.

Sample SPY_071221P435.

If you give this to TDSession.get_quotes it just works. It is way easier then to just create the correct text string vs having to parse the json.

I guess no one knew this. Anyways hope it helps someone.

If you do want to parse check out this article https://medium.com/analytics-vidhya/an-introduction-to-the-td-ameritrade-api-in-python-8c9d462e966c

base_url = 'https://api.tdameritrade.com/v1/marketdata/chains?&symbol={stock_ticker}\
&contractType={contract_type}&strike={strike}&fromDate={date}&toDate={date}'
endpoint = base_url.format(stock_ticker = stock,
contract_type = optionType,
strike = strikePrice,
date=optionDate)
page = requests.get(url=endpoint,
params={'apikey' : td_consumer_key})
content = json.loads(page.content)

print (content[dateMap][optionDate + ":" + dte][strikePrice][0]["last"])
