Ryan Sellers is a former open outcry market maker from Chicago who traded on the floor for years in the early 2000's. He's also the originator of the @OpenOutcrier Twitter handle, an invaluable resource for traders that started many of the day-to-day nuances we see on FinTwit nowadays. His team of traders and news junkies have turned their once casual Twitter appearances into a full fledged news feed service - we talk about the evolution of OOC, how his team got started, how they trade, what life was like on the open outcry floor, whether or not he remembers being at a club with me in Las Vegas this past summer and more.
