Murrey's stuff is based on some Gann basics and is interesting. Murrey himself definitely comes across as a raving lunatic though. And his writings are practically incomprehensible. He's about the worst ad for the method possible because it's tough to take anything he says seriously because he's always so raving, condescending, and hostile. Although there are definitiely people who drank the Kool Aid to whom he's the Second Coming and who are themselves about as raving as he.
However, there are groups using the basic ideas to trade that are neither "disciples" nor raving. Don't know if it's still going, but there was a trading room operated by traderbambu that used it profitably and was very rational.
As far as Murrey's software goes - a friend bought his end of day program and it was a pretty cheesy product (especially for $750). Have seen a lot of posts on another board about his realtime program apparently being a POS too - not to mention WAY too expensive. If you're interested, try one of the broader based realtime programs that includes similar functionality among its feature set (beware the esignal script though - when I tried it, it often produced intermittent incorrect results, especially on intraday charts).
Do a search on ET for "Murrey Math" and you should find prior threads that discussed it in more detail. Be aware though that there are as many raving detractors as there supporters, so some of the prior threads had some irrational mudslinging.
