It is "ceteris paribus". It means "with all other things being equal". You use it by stating what you think the outcome or effect will be, then follow up with ", ceteris paribus". Good luck.
I dunno about ceteris paribus, but you'll see a lot of "mutatis mutandis" mentioned in philosophy books. I solely attribute my stunted growth to that damn word. I get anal just hearing that word.
So .... yesterday was roll day and I noticed the following. ES vs NQ June (current) compared to March (old) contract:- ES vol 1.042 oi 0.411 NQ vol 0.887 oi 0.241 Wonder why NQ is a little slower making the roll? Never looked closely previously so I don't know if this is business as usual?
