Normally we only need to update "NFV" once maybe twice a day. Well today it is ballistic. At ~1189 now.
nitro, you seem to have a very useful model. NFV seemed to be an attractant today even though it seems unusual to have NFV>SPX. do you spend a lot of your time trading it yourself? you should spend more time on automation/programming. i am willing to trade your model (for a nominal fee) so that you could concentrate on automation.
