In the YQL console I'm typing this:
SELECT * FROM yahoo.finance.options WHERE symbol='IBM' AND expiration='2011-10-07'
but it does not return this week's options - it seems to be stuck on the monthly options.
here is a snippet from the reply below - does anyone know the trick to making it return weekly options?
