I've heard of a few groups in the area but have never met anyone from them. Check out: http://daytraders.meetup.com/115/ Also, whenever there is an options seminar by Thinkorswim in town or in Cincy alot of Indy traders are there. Check this link out, there is one coming up in early October: http://www.optionplanet.com/assembled/map.html
Thank you ryank! It'll be nice to actually find some people in person that share a common profession.
