it was a joke in poor taste, but you said educational not trying to sell anything. You didn't say on what subject matter. If you really want to see it check out Taj Mahal Guitar lesson one. Just something you'll find on Utube not commercially available anywhere else. I once saw a guy who recorded himself losing 15k on a Sunday night in ES when the mkt was closed for holiday on Monday and he only knew one word (the f*** word), then there was the one of the guy who claimed every 15 min bar on a bar chart was an entry on GBP.JPY.
otherwise, ET is the only place you'll find info from people who barely want to share but couldn't care less about selling. Sometimes traders enjoy talking about what they are doing or have done as long as they can stay anonymous and don't have to prove they are not lying.
What is it you want to do? What is it you want to learn?
