I attended Raschke's one day seminar at the Trader's Expo in NYC this year, after using a free trial some time last year in the stock room, and reading START SMARTS
Chat room gave me a feel for her thought process, and studying STREET SMARTS took me further into it, so when I attended her seminar i was not blown away by lots of unfamiliar, well thought out stuff
i went to the chat room for the educational part of it, and greatly enjoyed her intra-day discussions of market activity, etc
and, yes, her seminar was worthwhile and, although I don't trade her setups, i would do the Chicago seminar in a heartbeat, as the opportunity to study with a sharp trader, whose ego doesn't come in front of her analysis/discussion is priceless..IMO
