Hi Michael,

you might wanna try this little tool I have written, see /g/twsapi/topic/little_tool_for_option_chain/81408600?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,81408600
It basically frees you from doing all of this and provides a fast caching mechanism if? you reload your application.

Cheers,
Juergen
