I don't know if you are talking about a scan software or not. usually, a software deserve its merit. It is a higher price for one but not necessary high for others. Of course a lot programs indeed are craps. It all depends on how it relevant to your trading. I know of a lot programs with all kinds of different features. Keep in mind that if those who can make money, they don’t need to sell program for living. On the other hand, I wish some one can programme a scan software for me to scan some “particular patterns” that I’m interested in and willing to pay thousands of dollars.

If you are talking about a book. Then there is a book about patterns and (trading) opening range break out, which was written by a Russian engineer/immigrant. It is a good book in my view. I forgot the author’s name.

BTW, if you interested, there will be a convention in Feb 4-7, in Orlando, Fl, Gaylord Palms Resort Convention Center and an International Traders Expo in Feb 21-24 in New York, NY, Marriott Marquis Hotel, their phone number is: 1.800.970.4355 (US and Canada). Please note that I have no affiliation with them whatsoever.
