I am working on a small widget for my projects which basically looks like this. Futures for Yahoo Finance
How can I get the data for Natural Gas, Gasoline, Crude Oil, Heating Oil and their Change?. I want to retrieve those data via json maybe and create a box widget or a ticker. The Image attached is what I am trying to make. Thank you.
PS: I tried CLJ15.NYM Symbol for Crude Oil using yahoo.finance.quotes table in the YQL Console, but it did not work.
