I used to grab option chain data from yahoo web page, but today I found the page had been changed, in the new page, js is used, which means it's more difficult to retrieve option data from yahoo. Any good idea to solve this?
Yahoo's also recently ducked up their mobile web pages. I can't see charts anymore. Probably outsourced their development.
Actually, from what I saw it actually seems like they made it very easy to request data. For example: https://query2.finance.yahoo.com/v7...ted=true&lang=en-US®ion=US&date=1469145600 Gets IBM option chain for July 22, 2016. I didn't look too deeply but there are other parameters that let you filter or request different parts of the data. results are standard JSON Jerry Medved https://www.medvedtrader.com
if I told you, I would have to kill you Just opened the browser Development tools (CTRL+SHIFT+I), then loaded the page and looked for where the data was requested. The page loads a ton of stuff but usually the data requests are relatively easy to identify. Been doing it for 18 years, so it becomes second nature Jerry Medved https://www.medvedtrader.com
