In a quick search I found the following discussion related to Barchart. I have no Idea if this is useful in the current situation but I thought I would share this. Excuse me if this is irrelevant to the current issue.
(barchart) ms@mm:~/dev/barchart$ python quotes.py
python quotes.py
Barchart OnDemand Client: https://ondemand.websol.barchart.com/
Traceback (most recent call last):
File "quotes.py", line 9, in <module>
quotes = od.quote('AAPL,MSFT')['results']
File "/Users/ms/dev/barchart/lib/python2.7/site-packages/ondemand/ondemand_client.py", line 69, in quote
return self._do_call(self.endpoint + 'getQuote.json', params)
File "/Users/ms/dev/barchart/lib/python2.7/site-packages/ondemand/ondemand_client.py", line 55, in _do_call
raise OnDemandError('Request Failed: %s. Text: %s' % (resp.status_code, resp.text))
ondemand.ondemand_client.OnDemandError: Request Failed: 401. Text: API key is missing or not valid. If you are using a free API key, please make your requests to <a href="https://marketdata.websol.barchart.com">https://marketdata.websol.barchart.com</a>

@Schwarzschild https://github.com/Schwarzschild are you using a free API or do you have a paid subscription?
If so, you have to change the end_point as stated in the error message
If you are using a free API key, please make your requests to https://marketdata.websol.barchart.com https://marketdata.websol.barchart.com/
So your constructor would look like:
od = ondemand.OnDemandClient(api_key=key, end_point=https://marketdata.websol.barchart.com)

The following use to work for me to get the Delta of an Option:
=smfGetOptionQuotes("RS 9/21 2018 $100 call","5",,"B")
However, it no longer works. Is there currently a way to get the delta of an option?


Thanks,
Bob

I'm not aware of a source of delta now that Barchart is no longer available.

Hmm. Looks like NASDAQ has them, but it would be one web page per option
symbol. And the value is very different from what Barchart shows:

=smfGetTagContent("
https://www.nasdaq.com/symbol/rs/option-chain/180921C00100000-rs-call
","span",1,">Delta",,,,1)

Randy,

Thanks for the response. I tired this command:
=smfGetTagContent("https://www.nasdaq.com/symbol/rs/option-chain/180921C00100000-rs-call","span",1,">Delta",,,,1)


and it returned FALSE. What do you recommend?

I suspect it didn't copy correctly, and ended up with some comparison of
something to something. That is, "...=...". I've don't that before.

It looks like a hidden character is inserted within your message between
the "=" and the function name, so maybe that is causing some kind of issue.

Try copying just everything after the "=" as text and see what you get.
Mine gets pasted with an "?" sign in front. When I change that to "=", it
works fine.

Looks like https://www.nasdaq.com/symbol/rs/option-chain/greeks?dateindex=-1
has
the greeks for the entire chain.

Yes, but extremely awkward to use because it's in multiple pages...
