There are quite a few prop firms in Chicago. I know alot of traders that went through many of them in Chicago. PM me if you want some advice etc..
KIngofshorts what do you know about Tibra and Optiver that makes you "recommend" them? you used to work as a trader with them?
i think it's been mentioned enough on here. in fact I know it has. but a prop firm that doesn't require a license... well you know. just don't be surprised is all.
