There’s no reason a broker has to have an API if they’re not serving HFT, which most retail brokers do not. However, you can automate most brokers using the private API that their mobile app uses or by screen scraping their website.

IV will likely be highest on the options expiring immediately following the singular volatility event. So Dec 18 on a monthly or on an earlier weekly option if available. Earlier expirations will not include the event so their IV will be lower and later expirations will spread the singular...

Cross-domain security is an issue if you are reading data from one website while your script is running on another website. If you're sending requests with a non-browser tool or language (e.g. cURL, Python, Node.js) then you can just send the requests. If you're using Chrome, open the developer...

I tried this, down to $0.05 and still wasn't filled. At that point, I figured there's got to be some way to get more value out of it.
